Asteroid Ryugu samples continue to shed light on solar system history
Dec 13, 2022 (SPX)
The isotopic signatures show that Ryugu's composition is close to Ivuna-like carbonaceous chondrites, and that Ryugu-like material from the outer solar system a...
The 2022 Geminids meteor shower is approaching
Dec 05, 2022 (SPX)
During peak activity and perfect weather conditions, which are rare, the Geminids produce approximately 100-150 meteors per hour for viewing. However, this year...
Mars megatsunami may have been caused by Chicxulub-like asteroid impact
Dec 02, 2022 (SPX)
Previous research has proposed that an asteroid or comet impact within an ocean in the Martian northern lowlands may have caused a megatsunami approximately 3.4...
New minerals discovered in massive meteorite may reveal clues to asteroid formation
Dec 01, 2022 (SPX)
"Whenever you find a new mineral, it means that the actual geological conditions, the chemistry of the rock, was different than what's been found before," says ...
Small asteroids are probably young
Dec 01, 2022 (SPX)
Rules on the development of craters help with dating asteroids To explore the characteristics of asteroids, during the space mission Hayabusa2, a Small Carry-on...
Geologist studies asteroids and moondust to decode the history of the solar system
Dec 01, 2022 (SPX)
"I study space weathering: how space environments affect tiny mineral particles on planetary surfaces," said Thompson, an assistant professor in the Department ...
The sixth asteroid impact we saw coming
Nov 25, 2022 (ESA)
The new asteroid, now officially designated 2022 WJ1, was first imaged by the 1.5-metre Mt. Lemmon telescope at 04:53 UTC on 19 November, but the object was fir...
New research reveals space debris, invisible meteors and near-Earth asteroids
Nov 24, 2022 (SPX)
"My primary goal has been to carefully analyze radar measurements of meteors and space debris and evaluate the precision of the measurements. This is to improve...
NASA program predicted impact of small asteroid over Ontario, Canada
Nov 23, 2022 (JPL)

New observation method helps unlock secrets of UK meteorite
Nov 17, 2022 (SPX)
Denis Vida, a Western physics and astronomy postdoctoral associate, was a key contributor to the study. Combining data from five different meteor networks that ...
SwRI experiment helps predict effects of DART impact
Nov 02, 2022 (SPX)
NASA not only tracks near-Earth asteroids (NEAs) that could pose a possible impact threat to our home planet but is also exploring technology to deflect the pat...
Largest potentially hazardous asteroid detected in eight years
Nov 01, 2022 (SPX)

Spectral evolution of a dark asteroid surface after ten years of space weathering
Oct 28, 2022 (SPX)
This study is the first example that investigates spectral changes due to space weathering on the surface of an actual asteroid in the Solar System. Models base...
Arecibo Observatory scientists publish major study on near-earth asteroids
Oct 27, 2022 (SPX)
Using delay-Doppler radar observations collected from the observatory between December 2017 and December 2019, the study includes 191 asteroids' radar cross sec...
Scientists discover the source of one of the rarest groups of meteorites
Oct 25, 2022 (SPX)
Carbonaceous chondrites, such as the Winchcombe meteorite which fell to Earth and was retrieved in Gloucestershire in 2021, are an extremely rare group of meteo...
Shadow hunters capture Didymos asteroid eclipsing stars
Oct 21, 2022 (ESA)
