Astronomers have succeeded in measuring precisely the distance to a source on the other side of the galaxy, a region that has so far been…
Astronomers continue to study Cassini data on Saturn, providing us with images like this one showing the northern hemisphere from about 34 degrees above Saturn’s…
Using ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, astronomers reveal that Jupiter’s intense northern and southern lights pulse independently of each other. The study, published…
This Hubble image of the week shows Abell 665, which is located in the well-known northern constellation of Ursa Major. The Universe contains some truly…
Astronomers reveal that a small, recently discovered asteroid — or perhaps a comet — has entered our solar system from somewhere else in our galaxy….
Hubble has discovered a blistering hot planet outside our solar system where it “snows” titanium oxide on the planet’s permanent nighttime side. NASA’s Hubble Space…
Researchers, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star…
This newly released image from the Mars Reconnaissance Orbiter shows a small central portion of Hellas Planitia and shows a dune field with lots of…
Two new studies from NASA’s Dawn mission shed light on Ceres, revealing that the dwarf planet may have had a global ocean in the past….
The VLT Survey Telescope has captured the most detailed image yet of the lenticular galaxy NGC 1316 and its rich surroundings. Countless galaxies vie for…
NASA’s Mars Reconnaissance Orbiter (MRO) views layered sedimentary deposits on the surface of Mars. The layered sedimentary deposits inside the giant canyons of Mars have…
Astronomers recently discovered that spots on the surface of supergiant star Zeta Puppis are driving huge spiral structures in its stellar wind. Massive stars are…
New results from the Juno Spacecraft show that Jupiter’s gravitational field is askew, with different patterns in its northern and southern hemispheres. NASA’s Juno spacecraft…
This view from NASA’s Cassini Spacecraft shows Saturn’s graceful lanes of orbiting ice (rings) winding their way around the planet to pass beyond the horizon….
This newly released Hubble image of the weeks shows galaxy cluster WHL J24.3324-8.477 surrounded by many other galaxies. This NASA/ESA Hubble Space Telescope image is…
NASA’s Solar Dynamics Observatory captured a new image of a lunar transit when the Moon crossed the spacecraft’s view of the Sun. On October 19,…
NASA’s MAVEN Spacecraft reveals that Mars has an invisible magnetic “tail” that is twisted by interaction with the solar wind. NASA’s Mars Atmosphere and Volatile…
