Mars InSight lander seen in first images from space

Science Daily Astronomy - Thu, 2018-12-13 20:43
On Nov. 26, NASA's InSight mission knew the spacecraft touched down within an 81-mile-long (130-kilometer-long) landing ellipse on Mars. Now, the team has pinpointed InSight's exact location using images from HiRISE, a powerful camera onboard another NASA spacecraft, Mars Reconnaissance Orbiter (MRO).

Tangled magnetic fields power cosmic particle accelerators

Science Daily Astronomy - Thu, 2018-12-13 13:12
Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe. That's the result of a new computational study that simulated particle emissions from distant active galaxies.

Where did the hot Neptunes go? A shrinking planet holds the answer

Science Daily Astronomy - Thu, 2018-12-13 10:13
'Where did the hot Neptunes go?' This is the question astronomers have been asking for a long time, faced with the mysterious absence of planets the size of Neptune. Researchers have just discovered that one of these planets is losing its atmosphere at a frantic pace. This observation strengthens the theory that hot Neptunes have lost much of their atmosphere and turned into smaller planets called super-Earths.

Large population of potential young planets found in distant planetary systems

Science Daily Astronomy - Wed, 2018-12-12 14:46
Astronomers used the powerful ALMA telescope to discover that in other parts of the Milky Way Galaxy (seen here) there is potentially a large population of young planets -- similar in mass to Neptune or Jupiter -- at wide-orbit that are not detectable by other current planet searching techniques.

NASA's Juno mission halfway to Jupiter science

Science Daily Astronomy - Wed, 2018-12-12 14:42
On Dec. 21, NASA's Juno spacecraft will be 3,140 miles (5,053 kilometers) above Jupiter's cloud tops and hurtling by at a healthy clip of 128,802 mph (207,287 kilometers per hour). This will mark the solar-powered spacecraft's halfway point in data collection during its prime mission.

NASA's InSight takes its first selfie

Science Daily Astronomy - Wed, 2018-12-12 14:39
NASA's InSight lander used a camera on its robotic arm to take its first selfie -- a mosaic made up of 11 images. This is the same imaging process used by NASA's Curiosity rover mission, in which many overlapping pictures are taken and later stitched together.

Evidence for carbon-rich surface on Ceres

Science Daily Astronomy - Mon, 2018-12-10 11:58
Astronomers have concluded that the surface of dwarf planet Ceres is rich in organic matter. Data from NASA's Dawn spacecraft indicate that Ceres's surface may contain several times the concentration of carbon than is present in the most carbon-rich, primitive meteorites found on Earth.
