Astrophysics study suggests Venus may have swallowed its moon
21+ hour, 5+ min ago (555+ words) A California-based astrophysicist has presented a new theory to explain why Venus, the planet most like Earth in size, mass and structure, lacks its own moon. Call it a case of celestial cannibalism. The extremely slow speed at which Venus…...
MIT Research Could Lead to Refueling Depots on Mars
14+ hour, 58+ min ago (22+ words) MIT PhD candidate Lanie McKinney is developing technology to convert the chemicals in the Martian atmosphere into propellant to bring astronauts home....
Astronomy Picture of the Day - A Zodiacal Night
21+ hour, 1+ min ago (122+ words) Explanation: Also known as the false dawn, a luminous band of zodiacal light is captured in this dark night skyscape. The serene view was recorded just before the beginning of astronomical twilight during September's star party at the remote Hanle…...
NASA Struck Mars 5 Times, What the Craters Revealed Stunned Scientists
20+ hour, 55+ min ago (794+ words) NASA spacecraft debris created five fresh craters on Mars, allowing scientists to measure the strength of the planet’s surface in an unexpected way. NASA’s Perseverance rover mission unintentionally created five impact craters on Mars, giving scientists a rare opportunity to…...
On Deimos, orbital speed just above the surface is only about 14 km/h—around elite racewalking pace—while roughly 20 km/h would let you escape the tiny moon altogether.
1+ day, 2+ hour ago (1082+ words) JPL's measured gravity and radius put a surface-grazing Deimos orbit near 14.2 km/h and local escape near 20.1 km/h, although Mars and the moon's irregular shape complicate real flight....
A giant crater may reveal the origin of Mars’ doomed moon
1+ day, 5+ hour ago (923+ words) A massive crater on Mars’ moon Phobos may hide a dense region of compressed material that could reveal whether the moon is a captured asteroid or debris from an ancient impact on Mars. Japan’s upcoming MMX sample return mission could…...
Methone, a moon of Saturn only about three kilometres across, has no observed craters larger than 130 metres: its porous icy surface may slowly shift and erase impact scars, while Saturn’s tides and the moon’s rotation mould it into a smooth, egg-like shape.
1+ day, 9+ hour ago (1076+ words) Cassini's only close look at tiny Methone found no crater larger than about 130 metres. Its smooth shape points to an extraordinarily porous moon whose surface cannot preserve relief easily....
Today is International Astronomy Day: Learning through astronomy and space science
1+ day, 19+ hour ago (206+ words) The Hans India Astronomy offers students a way to understand the universe by combining observation, mathematics, physics and technology From studying planets and stars to examining distant galaxies, the field encourages learners to ask questions about how celestial objects form,…...
NASA’s Curiosity rover marks 5,000 days on Mars with special ‘postcard’
1+ day, 14+ hour ago (227+ words) A special "postcard" from Mars celebrates the Curiosity rover’s 5,000th day on the Red Planet. While parked at a sand ridge nicknamed “Chocolatal,” NASA’s exploratory robot used its black-and-white navigation cameras to capture panoramas at two times of day. The first…...
