HubbleSite NewsCenter -- Latest News Releases 20 Jul 2017, 17:00 UTC While photographing Mars, NASA’s Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Discovered in 1877, the diminutive, potato-shaped moon is so small that it appears star-like in the Hubble pictures. Phobos orbits Mars in just 7 hours and 39 minutes, which is faster than Mars rotates. The moon’s orbit is very slowly shrinking, meaning it will eventually shatter under Mars’ gravitational pull, or crash into the planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moon’s orbital path.
Europlanet Research Infrastructure 20 Jul 2017, 09:57 UTC The first observing run of a collaboration between amateur and professional astronomers to monitor our planetary neighbours has resulted in some of the best planetary images ever taken from the ground.
Harvard-Smithsonian Center for Astrophysics 19 Jul 2017, 18:10 UTC Physicists are capitalizing on a direct connection between the largest cosmic structures and the smallest known objects to use the universe as a "cosmological collider" and investigate new physics.

NASA's Goddard Space Flight Center 18 Jul 2017, 17:00 UTC A combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, suggests the center of our Milky Way contains a "trap" that concentrates some of the highest-energy cosmic rays, among the fastest particles in the galaxy.
NASA's Goddard Space Flight Center 17 Jul 2017, 17:00 UTC One night three months ago, Rosa Castro finished her dinner, opened her laptop, and uncovered a novel object that was neither planet nor star. Therapist by day and amateur astronomer by night, Castro joined the NASA-funded Backyard Worlds: Planet 9 citizen science project when it began in February — not knowing she would become one of four volunteers to help identify the project's first brown dwarf, formally known as WISEA J110125.95+540052.8.
