The United Nations has declared 2015 the International Year of Light, and to recognise the start of the event, the Chandra X-ray Center is releasing a set of images that combine data from telescopes tuned to different wavelengths of light.
The high resolution camera aboard Rosetta has captured a stunning view of comet 67P/Churyumov–Gerasimenko showing multiple jets streaming away from the surface.
A large swathe of the Andromeda Galaxy, our galactic next-door neighbour, is mapped in unprecedented detail in the largest NASA Hubble Space Telescope image ever assembled.
In celebration of its 25th anniversary, the Hubble Space Telescope has revisited the famous “Pillars of Creation”, providing astronomers with a sharper and wider view.
A decade ago, the Cassini probe made a New Year’s Eve close approach to Saturn’s moon Iapetus and captured astonishing views of its remarkable surface.
Located in the Fornax Galaxy Cluster some 60 million light-years from Earth, IC 335 is an edge-on lenticular system — an intermediate state in galaxy morphological classification schemes between true spiral and elliptical galaxies.
Tethys appears to be peeking out from behind Rhea in this image from the Cassini probe. Scientists believe that Tethys’ surprisingly high albedo is due to the water ice jets emerging from its neighbour, Enceladus.
The European Space Agency’s Philae lander captured this blurred view during its first bounce after first contacting the surface of comet 67P/Churyumov-Gerasimenko in November.
