Using powerful optics, astronomers have found a planet-like body, J1407b, with rings 200 times the size of Saturn's. This is an artist's depiction of the rings of planet J1407b, which are eclipsing a star.

A patch of stars appears to be missing in this image from the La Silla Observatory in Chile. But the stars are actually still there behind a cloud of gas and dust called Lynds Dark Nebula 483. The cloud is about 700 light years from Earth in the constellation Serpens (The Serpent).

NASA has captured a stunning new image of the so-called "Pillars of Creation," one of the space agency's most iconic discoveries. The giant columns of cold gas, in a small region of the Eagle Nebula, were popularized by a similar image taken by the Hubble Space Telescope in 1995.

TIME Science space Hubble Telescope Spots an Emoticon in Outer Space Hubble/ESA/NASA Galaxy cluster SDSS J1038+4849 It's actually a cluster of galaxies

In the center of this Hubble Telescope image is the galaxy cluster SDSS J1038+4849 and it appears to be smiling back at you.

The two orange eyes of the grinning face are actually two distant galaxies, and the peculiar smile was caused by an effect known as strong gravitational lensing.

Galaxy clusters are so large that they can create a strong gravitational pull that warps the time and space surrounding them. From afar this creates a distorted view of reality, known as a cosmic lens.

There are thousands of images within the Hubble database that have only been viewed by a few scientists. However, Hubble opens up its massive database to the public to search through. A version of this particular image was brought to attention by a contestant, Judy Smith, through the Hubbles Hidden Treasures image processing competition.

The Hubble space telescope captured three of Jupiter's largest moons in transit at the same time across the banded face of the planet.

The sharp photos released today by NASA were taken on January 24 with the Hubble telescope. They show three of Jupiter's biggest moons, Europa, Callisto and Io, moving together across the face of the gas-giant planet.

The three moons are known as Galilean moons since they were discovered by the scientist during the 17th century. With orbits ranging from two to 17 days, it's common for at least one of the moons to be seen orbiting the Jupiter. However, the convergence of the three is an occurrence so rare that NASA said it happens only once or twice per decade.

The fourth Galilean moon, Ganymede, was outside the Hubble's view and was not part of the celestial sight.

Of Jupiter's moons, the most interest has centered around Europa, which is thought to have elements that could make it hospitable to multi-cellular life.

Getting a closer look could soon be a reality. The $18.5 billion NASA budget recently proposed by the White House for next year includes money earmarked "for Planetary Science including formulation of a mission to Jupiters moon Europa."

Under its icy shell, Europa is believed to have an interior ocean that could perhaps be 10 times deeper than those on Earth, and include two to three times the volume of all liquid water on our planet.

Hubble Telescope Captures Images of Rare Jupiter Triple-Moon

NASA's Hubble Space Telescope has captured three of Jupiter's moons marching across the huge planet's disc, a stunning sight that happens only once or twice every 10 years.

The rare triple-moon conjunction on Jupiter, which Hubble witnessed on Jan. 24, involved Io, Callisto and Europa three of the gas giant's four Galilean moons (so named because they were discovered by astronomer Galileo Galilei in the early 17th century).

"The moons in these photos have distinctive colors. The ancient, cratered surface of Callisto is brownish; the smooth icy surface of Europa is yellow-white; and the volcanic, sulfur-dioxide surface of Io is orange," representatives of the Space Telescope Science Institute (STScI) in Baltimore, which operates Hubble, wrote in a statement today (Feb. 5).

"The apparent 'fuzziness' of some of the shadows depends on the moons' distances from Jupiter," they added. "The farther away a moon is from the planet, the softer the shadow, because the shadow is more spread out across the disk."

The conjunction lasted about 42 minutes. The fourth Galilean moon, Ganymede, was outside Hubble's field of view during the triple transit, STScI representatives said.

Volcanic Io is the innermost of the Galilean moons, completing one lap around Jupiter every 1.8 days. Europa, Ganymede and Callisto have orbital periods of 3.6, 7.2 and 16.7 days, respectively.

With a diameter of 3,270 miles (5,260 kilometers), Ganymede is the largest natural satellite in the solar system. Indeed, it's bigger than the planet Mercury.

Europa is the smallest Galilean moon, at 1,900 miles (3,100 km) wide, but it generates excitement and intrigue disproportionate to its size. The satellite harbors an ocean of liquid water beneath its icy shell, and this ocean is thought to be in contact with Europa's rocky mantle, making possible all kinds of interesting chemical reactions.

Indeed, many scientists regard Europa as the solar system's best bet to host alien life. NASA is mapping out a robotic mission to Europa, which agency officials say should be ready to launch by the mid-2020s.

Wow! Hubble Telescope Sees Rare 3-Moon Shadow Dance on Jupiter

Scientists working with the long-lived Hubble Space Telescope say that the intrepid eye on the sky could continue functioning through 2020, and even beyond.

Hubble is currently in good shape. The instruments repaired during the last Hubble servicing mission in 2009 have operated longer since the repairs than they did with the original hardware, Kenneth Sembach of the Space Telescope Science Institute said during a news conference in January at the 225th meeting of the American Astronomical Society.

Many of the other systems on Hubble are functioning well, even with the telescope reaching its 25th year in space in 2015. NASA did a study in 2013 evaluating Hubble's engineering and subsystems that ultimately showed a good likelihood that the telescope would continue functioning at least until 2020, Sembach said. [See amazing images taken by Hubble]

Operating the telescope through 2020 is an important goal for NASA. Hubble's successor NASA's James Webb Space Telescope (JWST) should launch in 2018, creating a one-two punch of space telescope observations for at least a couple years before Hubble's mission ends.

And officials are doing all they can to be sure that the spacecraft keeps working through at least that target date.

"We're conducting what we're calling the '2020 vision' for Hubble, and that is to make sure that the observatory is ready to run for at least five or six years to get at least a year of overlap with James Webb, if not more," Sembach said. "We're lucky in that we have very proactive engineering that's been going on over the last few years and continues to go on both at the [Space Telescope Science] Institute and at [NASA's] Goddard [Space Flight Center] to make sure that we're operating the observatory as safely and as effectively as we can. So, we're going to get to 2020."

JWST and Hubble are designed to observe somewhat different cosmic spectacles. JWST will extend Hubble's reach into the early universe, allowing scientists to potentially learn more about how the earliest galaxies formed.

If the two telescopes do function simultaneously, scientists might be able to observe one target using both observatories, giving researchers a more detailed spectrum of science from the cosmic target.

"The Hubble Space Telescope mission office and the James Webb Space Telescope mission office are discussing ways that we can allow people that have excellent science ideas that require both facilities to take data of the same targets to get those data sets on both missions," Jason Kalirai of the Space Telescope Science Institute said during the news conference. "We're in the process of putting together policies that are going to ensure that's possible."
