A study published Aug. 23 in AGU Advances by a team from MIT and the University of Arizona proposes that waves inside the buried ocean of Saturn's moon Enceladus carve the four parallel fissures that…

Draw every known rocky planet on one chart, how hard its star bakes it, against how firmly its gravity holds on, and a line appears. Below the line, worlds keep an atmosphere. Above it, they are…

Line up the rocky part of Earth against the Sun, element for element, and most of the list matches. Then you reach the elements that boil off easily, the ones that need somewhere cool and quiet to…

NASA astronaut Anil Menon and ESA astronaut Sophie Adenot installed a replacement high-speed antenna on the outside of the International Space Station on Aug. 25, finishing a repair the pair had…

Astronomers have measured the naked surface of comet 28P/Neujmin from more than 10 astronomical units out, and report that it reflects light differently from the asteroids whose color it otherwise…

NASA said on Aug. 25 that Pandora, a small satellite launched in January, has finished commissioning and started taking science observations of exoplanets and the stars they orbit. Pandora reached…

The Aerospace Corporation presented the first six months of on-orbit results for DiskSat, a satellite built as a disc 1 meter across and 2.5 centimeters deep, at the Small Satellite Conference in…

The spectra had been sitting in a public archive for years, taken for someone else's project, a planet hunt at the European Southern Observatory in Chile. On night after night in the spring of 2018…

Stand on the daylit side of TOI-561 b and there would be nothing underfoot but rock hot enough to run like water. It is a rocky planet a little larger than Earth, orbiting so close to its star that a…

Four researchers say they have extracted a planet-circling pressure wave directly from Mars weather data for the first time, using more than one Martian year of readings from the pressure sensor on…

An ISRO-led team has published the design, ground testing, and in-orbit performance of SHAPE, an instrument on the Propulsion Module of India's Chandrayaan-3 Moon mission that observes the whole…

In 1995, two Swiss astronomers watched a star named 51 Pegasi lurch toward and away from Earth on a four-day beat, and read in that tiny rhythm the presence of an unseen planet. The wobble was the…
