Saturn because of its rings and you can see some detail with a small telescope and Jupiter because you can see the 4 large moons changing their position and you can view the GRS and other cloud tops.. Neptune and Uranus just show up of point of light like stars. But they can still look at Neptune and Uranus through the large telescope they have today and the Hubble ST view them both .When voyager first flyby both planets we got the first real photos of how the planet look,at this time there was no telescope on the ground could see them,they knew that the planet was blue and some detail about what they are made of. But the space probe show they a world they wasn't expecting Uranus had very little cloud top unlike Jupiter or Saturn. Uranus just look like a blue ball and it show they the planet wasn't emitting that must heat.When the probe got the Neptune they was expecting to see another Uranus but Neptune was active emitting a good amount of heat from its core and had some white cloud tops,
There is talk to send a orbiter to Neptune but so far only talk no cash let,Done a report about this look in past pages...

The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains, the statuesque pillars that remain might be imagined as mythical beasts. Featured here is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy. This fairy, however, is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars. This great pillar, which is about 7,000 light years away, will likely evaporate away in about 100,000 years. The featured image in scientifically re-assigned colors was released in 2005 as part of the fifteenth anniversary celebration of the launch of the Hubble Space Telescope.

Highlights of the North Winter Sky
Image Credit & Copyright: Universe2go.com
The featured graphic gives a few highlights for Earth's northern hemisphere. Viewed as a clock face centered at the bottom, early (northern) winter sky events fan out toward the left, while late winter events are projected toward the right. Objects relatively close to Earth are illustrated, in general, as nearer to the cartoon figure with the telescope at the bottom center -- although almost everything pictured can be seen without a telescope. As happens during any season, constellations appear the same year to year, and, as usual, the Geminids meteor shower will peak in mid-December. Also as usual, the International Space Station (ISS) can be seen, at times, as a bright spot drifting across the sky after sunset. Less usual, the Moon is expected to pass nearly in front of several planets in early January. A treat this winter is Comet 46P/Wirtanen, already bright, will pass only 36 lunar distances from the Earth in mid-December, potentially making it easily visible to the unaided eye.

With the exception of Earth itself, which planet is your favorite? Since my favorite color is blue, I really like Neptun the most.
Although it's a Gas Giant, I'm impressed by it's deep blue color. I know it's extremly cold out there, but Neptun looks beautiful.
Of course I like Saturn with it's rings, but Neptun is different. Too bad, that Neptun is so very far away...
Well if planets are to be picked, then I choose PSR B1620-26 b, also known as the "Methuselah" or "the Genesis planet". It is said to be one of the oldest known extrasolar planets, about 12.7 billion years old. It is named after the Biblical figure, Methuselah, who is said to be the longest lived human in the Bible. Plus, I think the name "Methuselah" has a cool ring to it. ;)

BepiColombo, the joint ESA/JAXA spacecraft on a mission to Mercury, is now firing its thrusters for the first time in flight.
On Sunday, BepiColombo carried out the first successful manoeuver using two of its four electric propulsion thrusters. After more than a week of testing which saw each thruster individually and meticulously put through its paces, the intrepid explorer is now one step closer to reaching the innermost planet of the solar system.
BepiColombo left Earth on 20 October 2018, and after the first few critical days in space and the initial weeks of in-orbit commissioning, its Mercury Transfer Module (MTM) is now revving up the high-tech ion thrusters.
The most powerful and high-performance electric propulsion system ever flown, these electric blue thrusters had not been tested in space until now.
It is these glowing power-packs that will propel the two science orbiters – the Mercury Planetary Orbiter and Mercury Magnetospheric Orbiter – on the seven-year cruise to the least explored planet of the inner solar system.
"Electric propulsion technology is very novel and extremely delicate," explains Elsa Montagnon, Spacecraft Operations Manager for BepiColombo.


Twin ion thrusters firing. Credit: QinetiQ"This means BepiColombo's four thrusters had to be thoroughly checked following the launch, by slowly turning each on, one by one, and closely monitoring their functioning and effect on the spacecraft."

Testing took place during a unique window, in which BepiColombo remained in continuous view of ground-based antennas and communications between the spacecraft and those controlling it could be constantly maintained.
This was the only chance to check in detail the functioning of this fundamental part of the spacecraft, as when routine firing begins in mid-December, the position of the spacecraft will mean its antennas will not be pointing at Earth, making it less visible to operators at mission control.
The first fire
On 20 November at 11:33 UTC (12:33 CET), the first of BepiColombo's thrusters entered Thrust Mode with a force of 75 mN (millinewtons). With this BepiColombo was firing in space for the very first time.
Three hours later, the newly awakened thruster was really put through its paces as commands from mission control directed it to go full throttle, ramping up to 125mN – equivalent to holding an AAA battery at sea level.

This may not sound like much, but this thruster was now working at the maximum thrust planned to be used during the life of the mission.

Thrust mode was maintained for five hours before BepiColombo transitioned back to Normal Mode. The entire time, ESA's Malargüe antenna in Argentina was in communication with the now glowing blue spacecraft – the colour of the plasma generated by the thruster as it burned through the xenon propellant.
These steps were then repeated for each of the other three thrusters over the next days, having only a tiny effect on BepiColombo's overall trajectory.
The small effects that were observed allowed the Flight Dynamics team to assess the thruster performance in precise detail: analysis of the first two firings reveals that the spacecraft was performing within 2% of its expected value. Analysis of the last two firings is ongoing.
Twenty-two arcs to go
"To see the thrusters working for the first time in space was an exciting moment and a big relief. BepiColombo's seven year trip to Mercury will include 22 ion thrust arcs – and we absolutely need healthy and well performing thrusters for this long trip," explains Paolo Ferri, ESA's Head of Operations.


Animation visualising BepiColombo’s journey to Mercury. Credit: European Space Agency"Each thruster burn arc will last for extended periods of up to two months, providing the same acceleration from less fuel compared to traditional, high-energy chemical burns that last for minutes or hours."

During each long-duration burn the engines do take eight hour pauses, once a week, to allow the ground to perform navigation measurements in quiet dynamic conditions.
The first routine electric propulsion thrust arc will begin in mid-December, steering BepiColombo on its interplanetary trajectory and optimising its orbit ahead of its swing-by of Earth in April 2020.
Travelling some nine billion kilometers in total, BepiColombo will take nine flybys at Earth, Venus and Mercury, looping around the Sun 18 times.
By late 2025 the transfer module's work will be done: it will separate, allowing the two science orbiters to be captured by Mercury's gravity, studying the planet and its environment, along with its interaction with the solar wind, from complementary orbits.
"We put our trust in the thrusters and they have not let us down. We are now on our way to Mercury with electro-mobility," concludes Günther Hasinger, ESA Director of Science.
"This brings us an important step closer to unlocking the secrets of the mysterious innermost planet and ultimately, the formation of our solar system."

The Ion engine would be a key engine for all space flight...Because unlike old rocket once the fuel is gone it dead weight.Ion engine can be turn on for a long time but they gain speed slowly but this is depended on the power source....If like on Star trek and other show if we had that power system you could just dump power into it and in little time you could get up to light speed and beyond...
A ion engine could get a a Orbiter to Pluto in less than 5 years,an orbiter to Neptune in about 4 years.Man space flight to Mars inless than 3 month,if Mars is close to the Earth which it does every few years.
Some people believe that Mercury was once a Jupiter(gas planet) size planet while the solar system was forming the gas planet got to close to ours Sun and through billion of year the sun blow the gas away.So we might be seeing a core of giant planet.Because Mercury has a very large metal core....

The Mars lander InSight done a first time thing on Mars .Its recorded the sound of the winds on Mars.
This is the first time on the surface of Mars that we've had instruments that can detect up to the frequency that humans can hear,
To get high-quality data from the incredibly sensitive seismometer onboard the lander, the team needs to be able to cancel out all the commotion coming from the Martian surface, looking only at signals coming from inside the planet. Because wind gusts can trick the seismometer, the lander is equipped with an air pressure sensor to isolate that background noise.
NASA try to design a noise-cancellation headphone system for our seismometer,

But scientists warned not to get too attached to these recordings, because they won't last long. The team is itching to deploy the seismometer and its protective cover, with the air pressure sensor nestled inside of that shield. When InSight is conducting its science mission, the seismometer won't be able to hear the wind, attuned only to the grumblings of the planet's interior.

I wonder if there are other planets with intelligent life, where homosexuality is also possible... :rolleyes:
One day it might happen on the Earth when everyone just except people for who they are and what they can do....
You know do what God wants us to do just love people for what they are and he would judge them,that is his job anyway not ours.
They was going to stone a women to death for having sex with another men(not her old men) ,They past a stone to Jesus and he said whom ever without sin can throw it .And people got it and let the women go.....
But he was saying that human aren't fit to judge another people....
On some syfy like Star Trek they just except you for who you are ...In one show it was alien race that was judging one of there people for being female(that race had no sexes-male/female)
But one day I hope we are able to grow up......One day we would be able to fix people like no one rapist and etc....They would be able to detect the seed of criminal behavior ..

One of NASA longest mission has reach interstellar space. Launch in 1977.Voyager 2 was the first to launch. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. Had Voyager 1 been unable to perform the Titan flyby, the trajectory of Voyager 2 could have been altered to explore Titan, forgoing any visit to Uranus and Neptune. Voyager 1 was not launched on a trajectory that would have allowed it to continue to Uranus and Neptune, but could have continued from Saturn to Pluto without exploring Titan.You see we could had saw Pluto ages ago.But Titan was a moon with some "air" plus they didn't know at the time that the space probe would last that long.I guess NASA guess wrong...
As NASA’s Voyager 2 spacecraft enters interstellar space, project officials have high hopes that it and its twin spacecraft will continue to operate for as long as a decade.
NASA announced Dec. 10 that Voyager 2 passed what is known as the heliopause, the boundary between where the solar wind from the sun dominates and where the interstellar medium is dominant. That crossing, around Nov. 5, was detected by Voyager 2 in the form of a sharp drop in solar wind particles and corresponding increase in galactic cosmic rays detected by the spacecraft’s instruments.
The discovery, announced at the Fall Meeting of the American Geophysical Union here, comes six years after Voyager 1 also crossed the heliopause into interstellar space.
“This is a very exciting time again in Voyager’s 41-year journey,” said Ed Stone, Voyager project scientist at Caltech and former director of the Jet Propulsion Laboratory, during a press conference announcing the discovery.
The signature of the heliopause crossing from Voyager 2 is not quite the same as Voyager 1, Stone noted. “That’s what makes it interesting,” he said. “We’re in a different place — one is in the northern hemisphere and the other is in the southern hemisphere — and it’s a different time in the solar cycle. We would have been amazed if it looked the same.”
With both Voyager 1 and Voyager 2 beyond the heliopause, scientists are eager to combine those measurements with those from spacecraft and instruments within the sun’s heliosphere. “I’ve been studying galactic cosmic rays for many years from within our heliosphere,” said Georgia Denolfo, a space scientist at NASA’s Goddard Space Flight Center, at the press conference. “So it’s especially exciting to be able to think that we will be having a mission in the very same space that I have been studying, and many others, from afar.”
“I often get asked, ‘Is this it for Voyager?’” said Nicky Fox, director of the heliophysics division at NASA Headquarters. “Absolutely not. This is really for me the beginning of a new era of heliophysics science.”
Project officials are hopeful that this new era can last for several years, despite the age of the two Voyager spacecraft. Both were launched within weeks of each other in 1977 on missions to fly by Jupiter and Saturn. Voyager 2 also made flybys of Uranus and Neptune.
“Both spacecraft are very healthy, if you consider them senior citizens,” said Suzanne Dodd, Voyager project manager at JPL. “They are operating just fine.”
The spacecraft, powered by radioisotope thermoelectric generators (RTGs), are gradually losing power as their plutonium power sources decay. Dodd said the power produced by each spacecraft’s RTG is declining by about four watts per year, and the heat they generate that keeps the spacecraft warm is also declining.
Dodd said they’re closely watching the temperatures on Voyager 2, which are approaching the freezing point for its hydrazine fuel. “So we have to make a lot of trades, particularly with Voyager 2, between power and thermal,” she said.
As the power levels continue to decline, project officials will have to turn off some of the instruments on each spacecraft. “The difficult decisions are going to be made by Dr. Stone and the science team on which instruments to turn off first,” she said. “Those decisions will be made with getting the most science value back.”
Dodd said it’s possible for each spacecraft to continue operating for up to 10 more years. “My own personal goal would be to get these spacecraft to last 50 years” from their 1977 launch, she said. “If we get out to 2027, that will be a 50-year mission. I think that would be fantastic.”

They turn off the cameras and spectrograph devices 1st long ago because after it flyby of Neptune there was nothing to look at. Termination of Digital Tape Recorder (DTR) operations (It was no longer needed due to a failure on the High Waveform Receiver on the Plasma Wave Subsystem (PWS) on June 30, 2002 ).Power off Planetary Radio Astronomy Experiment (PRA) .Termination of gyroscopic operations ...Initiate instrument power sharing around 2020 .
Remember the space probes had some problems being so old and its now working beyond it design lifetime and remember keeping the space probe heater on take alot of power...And its power source is going down 4 watt/year..You have to keep the fuel warm up because that is the only thing keep the space probe antenna aim at the earth.Both Voyager had done a good job.
Both Pioneer 10 and 11
1544625587550.png
Picture above also reach interstellar space but there power system doesn't make the power need to run the radio
There was talk about making a space probe to go out into interstellar space.Its would used atomic engine and take less than 9 years to reach Voyagers. but so far no funding...There was another one that would use RTG and ion engine..But they can make a atomic reactor that would make its own fuel and last a very long time unlike RTGs which work by heat produce by radioactive element..

This probe is to take Mars temperate and heart beat.
While the past one was design to look for signs of life...
Sound and Light Captured by Mars InSight
Your arm on Mars has unusual powers. For one thing it is nearly 2 meters long, has a scoop and grapple built into its hand, and has a camera built into its forearm. For another, it will soon deploy your ear -- a sensitive seismometer that will listen for distant rumblings -- onto the surface of Mars. Your SEISmomet-ear is the orange box in the foreground, while the gray dome behind it will be its protective cover. Your arm is attached to the InSight robotic lander that touched down on Mars two weeks ago. Somewhat unexpectedly, your ear has already heard something -- slight vibrations caused by the Martian wind flowing over the solar panels. Light from the Sun is being collected by the solar panels, part of one being visible on the far right. Actually, at the present time, you have two arms operating on Mars, but they are separated by about 600 kilometers. That's because your other active arm is connected to the Curiosity rover exploring a distant crater. Taken a week ago, rusty soil and rocks are visible in the featured image beyond Insight, as well as the orange sky of Mars.

Put on your red/blue glasses and float next to asteroid 101955 Bennu. Shaped like a spinning top toy with boulders littering its rough surface, the tiny Solar System world is about 1 Empire State Building (less than 500 meters) across. Frames used to construct this 3D anaglyph were taken by PolyCam on board the OSIRIS_REx spacecraft on December 3 from a distance of about 80 kilometers. Now settling in to explore Bennu from orbit, the OSIRIS-REx mission is expected to deliver samples of the asteroid to planet Earth in 2023. Samples of dust from another asteroid will streak through Earth's atmosphere much sooner though, when the Geminid meteor shower peaks in predawn skies on December 14. The parent body for the annual Geminids is asteroid 3200 Phaethon.

Cetus Galaxies and Supernova
Large spiral galaxy NGC 1055 at top left joins spiral Messier 77 (bottom right) in this cosmic view toward the aquatic constellation Cetus. The narrowed, dusty appearance of edge-on spiral NGC 1055 contrasts nicely with the face-on view of M77's bright nucleus and spiral arms. Both over 100,000 light-years across, the pair are dominant members of a small galaxy group about 60 million light-years away. At that estimated distance, M77 is one of the most remote objects in Charles Messier's catalog, and is separated from fellow island universe NGC 1055 by at least 500,000 light-years. The field of view is about the size of the full Moon on the sky and includes colorful foreground Milky Way stars along with more distant background galaxies. Taken on November 28, the sharp image also includes newly discovered supernova SN2018ivc, its location indicated in the arms of M77. The light from the explosion of one of M77's massive stars was discovered by telescopes on planet Earth only a few days earlier on November 24.

Phobos: Doomed Moon of Mars .
Mars have no natural satellite(A moon that form when the planet was form)Its has capture 3 object that got to close to Mars.
This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic. The origin of the Martian moons is unknown, though, with a leading hypothesis holding that they are captured asteroids. The larger moon, at 25-kilometers across, is Phobos, and is indeed seen to be a cratered, asteroid-like object in this false-colored image mosaic taken by the robotic Viking 1 mission in 1978. A recent analysis of the unusual long grooves seen on Phobos indicates that they may result from boulders rolling away from the giant impact that created the crater on the upper left: Stickney Crater. Phobos orbits so close to Mars - about 5,800 kilometers above the surface compared to 400,000 kilometers for our Moon - that gravitational tidal forces are dragging it down. The ultimate result will be for Phobos to break up in orbit and then crash down onto the Martian surface in about 50 million years.

Wednesday, December 12, 2018: A glowing nebula surrounds the binary star system R Aquarii in this view from the European Southern Observatory's Very Large Telescope. Located 700 light-years from Earth, R Aquarii consists of a red giant star that is losing material to its companion, a hot white dwarf. Bursts of stellar material coming from the red giant contribute to the surrounding nebula, known as Cederblad 211 ..

Wednesday, November 7, 2018:Jupiter's moon Io peeks out from behind the planet's horizon in this image from the JunoCam instrument on NASA's Juno spacecraft. Citizen scientists Gerald Eichstädt and Justin Cowart processed the image using raw data Juno acquired during its 16th close flyby of the giant gas planet on Oct. 28. At the time, Juno was about 9,300 miles (15,000 kilometers) above Jupiter's cloud tops. You see NASA make all the raw data from the JUno Camera for public to access and use ,some of the people made some interesting photo,Some of the ideas the pro are using now to show details in interesting ways...

Methane Bubbles Frozen in Lake Baikal -There is alot of methane Frozen if it all become free we have a problem.
What are these bubbles frozen into Lake Baikal? Methane. Lake Baikal, a UNESCO World Heritage Site in Russia, is the world's largest (by volume), oldest, and deepest lake, containing over 20% of the world's fresh water. The lake is also a vast storehouse of methane, a greenhouse gas that, if released, could potentially increase the amount of infrared light absorbed by Earth's atmosphere, and so increase the average temperature of the entire planet. Fortunately, the amount of methane currently bubbling out is not climatologically important. It is not clear what would happen, though, were temperatures to significantly increase in the region, or if the water level in Lake Baikal were to drop. Pictured, bubbles of rising methane froze during winter into the exceptionally clear ice covering the lake.

Jupiter in UV light---Photo by Hubble ST-Most of the UV is block by our air,but some get through which cause sun tan and burns and if you get too much it cause skin cancer .The O zone layer block it...
To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and (not pictured) infrared light. Featured from 2017, Jupiter appears different in near ultraviolet light, partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, are brightest in near ultraviolet, and so here appear (false-color) pink. Jupiter's largest moon Ganymede appears on the upper left. Juno continues on its looping 53-day orbits around Jupiter,
NASA was going to make the orbit 11 days but the rocket need to do this had some problem so NASA decide to leave it in its 53 day orbit.This long orbit was to take the space probe outside of a very strong radiation area close to Jupiter .The space probe is made out of stuff that is design to protect it from that radiation but even with this most space probes would burn out with a few years.
