The Week's Coolest Space Images

This color-enhanced image of a massive, raging storm in Jupiter's northern hemisphere was captured by NASA's Juno spacecraft during its ninth close flyby of the gas giant planet.

Jupiter's Gorgeous Southern Hemisphere


See Jupiter's southern hemisphere in beautiful detail in this new image taken by NASA's Juno spacecraft. The color-enhanced view captures one of the white ovals in the "String of Pearls," one of eight massive rotating storms at 40 degrees south latitude on the gas giant planet.

Phobos Orbiting Mars



The sharp eye of the NASA/ESA Hubble Space Telescope captured the tiny moon Phobos during its orbital trek around Mars on 12 May 2016. The observations were intended to photograph Mars while it was on its closest approach to Earth along its orbit, so the moon's cameo appearance was a bonus.

When Black Holes Collide (Illustration)


Most large galaxies have a central supermassive black hole. When galaxies collide, their central black holes tend to spiral toward each other, releasing gravitational waves in their cosmic dance. 

A Giant Cosmic Bubble


Measuring more than 300 000 light-years across, three times the diameter of the Milky Way, this colourful bubble of ionised gas is the biggest to ever have been discovered.

The Planet Ross 128 b (Illustration)


This artist's impression shows the temperate planet Ross 128 b, with its red dwarf parent star in the background. This planet, which lies only 11 light-years from Earth, was found by a team using ESO's unique planet-hunting HARPS instrument.



The team found that the hot spots had very different characteristics. The X-ray emission at Jupiter's south pole consistently pulsed every 11 minutes, but the X-rays seen from the north pole were erratic, increasing and decreasing in brightness — seemingly independent of the emission from the south pole.

Pandora, The Would-Be Perturber


As Cassini hurtled toward its fatal encounter with Saturn, the spacecraft turned to catch this final look at Saturn's moon Pandora next to the thin line of the F ring.

Illustration Of The Dust Belts Around Proxima Centauri


This artist's impression shows how the newly discovered belts of dust around the closest star to the Solar System, Proxima Centauri, may look. 

Asteroids Photobombing Distant Galaxies


Intruding across the picture are asteroid trails that appear as curved or S-shaped streaks. Rather than leaving one long trail, the asteroids appear in multiple Hubble exposures that have been combined into one image.

Winds Blowing On A Dying Star


Stars like our Sun constantly eject large amounts of gas and dust into space, but over their lifetimes the levels of this activity change [...] One such stage of development is the asymptotic giant branch (AGB) near a star's end of life. Dust around these stars plays an important role in regulating stellar winds.



From Hot To Hottest (Header Image)
This sequence of images shows the sun from its surface to its upper atmosphere all taken at about the same time (Oct. 27, 2017). The first shows the surface of the sun in filtered white light; the other seven images were taken in different wavelengths of extreme ultraviolet light.

Hiding Under The Dust On Mars


On a part of "Vera Rubin Ridge" where rover-team researchers sought to determine whether dust coatings are hiding rocks' hematite content, the Mast Camera (Mastcam) on NASA's Curiosity Mars rover took this image of a rock surface that had been brushed with the rover's Dust Removal Tool.

Illustration Of Polluted White Dwarf


This artist's concept shows an exoplanet and debris disk orbiting a polluted white dwarf. White dwarfs are dim, dense remnants of stars similar to the Sun that have exhausted their nuclear fuel and blown off their outer layers.

Illustration Of Black Hole With Jet


Black holes are famous for being ravenous eaters, but they do not eat everything that falls toward them. A small portion of material gets shot back out in powerful jets of hot gas, called plasma, that can wreak havoc on their surroundings.

Clues To Ceres' Internal Structure


The colorful map overlaid at right shows variations in Ceres' gravity field measured by Dawn, and gives scientists hints about the dwarf planet's internal structure.
