ESA Science & Technology 25 Jul 2018, 14:00 UTC Evidence for the Red Planet's watery past is prevalent across its surface in the form of vast dried-out river valley networks and gigantic outflow channels clearly imaged by orbiting spacecraft. Orbiters, together with landers and rovers exploring the martian surface, also discovered minerals that can only form in the presence of liquid water.
NASA's Jet Propulsion Laboratory News and Features 24 Jul 2018, 22:11 UTC With its dark, heavily cratered surface interrupted by tantalizing bright spots, Ceres may not remind you of our home planet Earth at first glance. The dwarf planet, which orbits the Sun in the vast asteroid belt between Mars and Jupiter, is also far smaller than Earth (in both mass and diameter). With its frigid temperature and lack of atmosphere, we're pretty sure Ceres can't support life as we know it. But these two bodies, Ceres and Earth, formed from similar materials in our solar system. And, after combing through thousands of images from NASA's Dawn spacecraft, which has been orbiting Ceres since 2015, scientists have spotted many features on Ceres that look like formations they've seen on Earth.
ESA Top News 24 Jul 2018, 13:00 UTC The launch of Aeolus — ESA’s mission to map Earth’s wind in real-time — is getting tantalisingly close, with the satellite due for lift-off on 21 August from Europe’s Spaceport in Kourou, French Guiana. With the wind in their sails, mission teams are busily preparing this unique satellite for its upcoming journey.
NASA's Jet Propulsion Laboratory News and Features 23 Jul 2018, 15:45 UTC New comprehensive mapping of the radiation pummeling Jupiter's icy moon Europa reveals where scientists should look -- and how deep they'll have to go -- when searching for signs of habitability and biosignatures.
NASA's Goddard Space Flight Center 20 Jul 2018, 13:25 UTC At first glance, it may seem as though this image was taken through a faulty lens, but the mind-bending distortions visible in this impressive image taken with Hubble’s Wide Field Camera 3 are actually caused by a cosmic phenomenon.
MIT 18 Jul 2018, 14:59 UTC For nearly a century, astronomers have puzzled over the curious variability of young stars residing in the Taurus-Auriga constellation some 450 light years from Earth. One star in particular has drawn astronomers’ attention. Every few decades, the star’s light has faded briefly before brightening again. In recent years, astronomers have observed the star dimming more frequently, and for longer periods, raising the question: What is repeatedly obscuring the star? The answer, astronomers believe, could shed light on some of the chaotic processes that take place early in a star’s development. Now physicists from MIT and elsewhere have observed the star, named RW Aur A, using NASA’s Chandra X-Ray Observatory. They’ve found evidence for what may have caused its most recent dimming event: a collision of two infant planetary bodies, which produced in its aftermath a dense cloud of gas and dust. As this planetary debris fell into the star, it generated a thick veil, temporarily obscuring the star’s light.
ESA Top News 18 Jul 2018, 13:00 UTC New research using a decade of data from ESA’s Mars Express has found clear signs of the complex martian atmosphere acting as a single, interconnected system, with processes occurring at low and mid levels significantly affecting those seen higher up.
ESO Top News 18 Jul 2018, 10:00 UTC ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope.
