Using the powerful 570-megapixel Dark Energy Camera (DECam) in Chile, astronomers just ten days ago discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System. The orbit of the approximately ...
Researchers have developed a novel technique to investigate the dynamics of the early solar system by analyzing magnetites in meteorites utilizing the wave nature of electrons.
A close examination of the millimeter-wavelength emissions from the asteroid Psyche, which NASA intends to visit in 2026, has produced the first temperature map of the object, providing new insight into its surface properties. ...
NASA's first spacecraft to explore the Trojan asteroids arrived Friday, July 30, at the agency's Kennedy Space Center (KSC) in Florida. It is now in a cleanroom at nearby Astrotech, ready to begin final preparations for its ...
Two asteroids (203 Pompeja and 269 Justitia) have been discovered with a redder spectrum than any other object in the asteroid belt between Mars and Jupiter. The discovery was led by HASEGAWA Sunao, Associate Senior Researcher ...
The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 66 million years ago likely came from the outer half of the main asteroid belt, a region previously thought to produce few impactors. ...
