Nov. 25, 2024 — When Voyager 2 flew by Uranus and Neptune 40 years ago, astronomers were surprised that it detected no global dipole magnetic fields, like Earth's. The explanation: the ice giants are layered and unmixed, which prevents large scale convection to ...
Aug. 22, 2024 — Researchers studying meteor showers have found that not all comets crumble the same way when they approach the Sun. In a new study, they ascribe the differences to the conditions in the protoplanetary disk where comets formed 4.5 billion years ...
July 9, 2024 — A international team of astronomers has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising 'super-Earth' covered in ice or ...
May 23, 2024 — While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar ...
