Forskare har identifierat en uråldrig planetfabrik utanför Jupiter

Forskare har spårat ursprunget hos varierande tidiga rymdstenar till en dammfälla precis utanför Jupiters omloppsbana. Resultaten kommer från datorsimuleringar som matchar meteoritsammansättningar funna på jorden. De tyder på att denna region producerade flera generationer av planetesimaler under miljontals år.

En studie från Max Planck Institute for Solar System Research visar att en ring av högre gastryck bortom Jupiter fångade in damm och småstenar. Detta möjliggjorde bildandet av planetesimaler med varierande sammansättning mellan två och fyra miljoner år efter att solsystemet började formas för 4,6 miljarder år sedan.

Meteorite points to lost moon-sized protoplanet in early Solar System

A meteorite found in the Sahara Desert has provided the first direct evidence of a massive protoplanet that orbited the young Sun more than 4.5 billion years ago. The object, comparable in size to the Moon, was destroyed in a collision, leaving fragments that reached Earth. Researchers say the discovery reveals a previously unknown path in early planet formation.

Scientists discover unusual inside-out planetary system

Astronomers have found a planetary system around a red dwarf star where a rocky world orbits beyond two gas giants, challenging standard models of how planets form. The discovery around LHS 1903 suggests planets may arise sequentially rather than all at once.

NASA's Hubble Space Telescope has imaged the largest known protoplanetary disk, revealing a turbulent and asymmetric structure around a young star. The disk, nicknamed Dracula's Chivito, stretches nearly 400 billion miles across and lies about 1,000 light-years from Earth.

Japanese astronomers detect thin atmosphere on small trans-Neptunian object 2002 XV93

A team of astronomers in Japan has discovered evidence of a faint atmosphere surrounding the small trans-Neptunian object 2002 XV93. Previously, only Pluto was known to retain an atmosphere among bodies beyond Neptune due to its stronger gravity. The finding, made via a rare stellar occultation on January 10, 2024 and published in Nature Astronomy, indicates a short-lived atmosphere requiring continuous replenishment.
