(Phys.org)—European astronomers report the detection of a new extrasolar world several times more massive than Earth. The newly found exoplanet, classified as a so-called “super-Earth,” is circling a nearby star designated GJ 625. The researchers detailed their finding in a paper published May 18 on arXiv.org.
A new NASA mission, the Neutron Star Interior Composition Explorer (NICER), is headed for the International Space Station next month to observe one of the strangest observable objects in the universe. Launching aboard SpaceX’s CRS-11 commercial resupply mission, NICER will be installed aboard the orbiting laboratory as the first mission dedicated to studying neutron stars, a type of collapsed star that is so dense scientists are unsure how matter behaves deep inside it.
Scientists are a step closer to understanding the inner-workings of the universe following the laying of the first stone, and construction starting on the world’s largest optical and infrared telescope.
On Oct. 13, 2014 something very strange happened to the camera aboard NASA’s Lunar Reconnaissance Orbiter (LRO). The Lunar Reconnaissance Orbiter Camera (LROC), which normally produces beautifully clear images of the lunar surface, produced an image that was wild and jittery. From the sudden and jagged pattern apparent in the image, the LROC team determined that the camera must have been hit by a tiny meteoroid, a small object in space.
Almost two billion years ago, a 10-kilometre-wide chunk of space slammed down into rock near what is now the city of Sudbury. Now, scientists from Western University and the University of Portsmouth are marrying details of that meteorite impact with technology that measures surrounding crystal fragments as a way to date other ancient meteorite strikes.
On May 25, 2017, NASA’s Solar Dynamics Observatory, or SDO, saw a partial solar eclipse in space when it caught the moon passing in front of the sun. The lunar transit lasted almost an hour, between 2:24 and 3:17 p.m. EDT, with the moon covering about 89 percent of the sun at the peak of its journey across the sun’s face. The moon’s crisp horizon can be seen from this view because the moon has no atmosphere to distort the sunlight.
This sequence of enhanced-color images shows how quickly the viewing geometry changes for NASA’s Juno spacecraft as it swoops by Jupiter. The images were obtained by JunoCam.
On New Year’s Day 2019, more than 4 billion miles from home, NASA’s New Horizons spacecraft will race past a small Kuiper Belt object known as 2014 MU69 – making this rocky remnant of planetary formation the farthest object ever encountered by any spacecraft.
New observations about the extreme conditions of Jupiter’s weather and magnetic fields by University of Leicester astronomers have contributed to the revelations and insights coming from the first close passes of Jupiter by NASA’s Juno mission, announced today (25 May).
