Forskare upptäcker ovanligt planetsystem med omvänd ordning

Astronomer har hittat ett planetsystem kring en röd dvärgstjärna där en stenplanet kretsar utanför två gasjättar, vilket utmanar standardmodeller för hur planeter bildas. Upptäckten kring LHS 1903 tyder på att planeter kan uppstå sekventiellt snarare än samtidigt.

Forskare ledda av Thomas Wilson vid University of Warwick identifierade systemet med fyra planeter genom att använda data från flera teleskop, inklusive Europeiska rymdorganisationens satellit Cheops. Planeterna följer en oväntad ordning med sten, gas, gas och sten, där den yttersta planeten verkar ha bildats i en gasfattig miljö efter att de andra redan tagit form.

Unusual planet pair challenges traditional formation models

Astronomers have identified a rare planetary system 190 light-years from Earth featuring a hot Jupiter sharing its orbit with a mini-Neptune closer to the star. This configuration was once considered nearly impossible. New observations from the James Webb Space Telescope provide fresh insights into how the planets formed.

Dying stars devour nearby giant planets, astronomers find

4 april 2026 Rapporterad av AI

Astronomers have discovered that aging stars expanding into red giants are engulfing close-orbiting giant planets. A study of nearly half a million stars shows fewer such planets around more evolved red giants, suggesting many have been destroyed. The findings come from data collected by NASA's Transiting Exoplanet Survey Satellite.

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.

Simulation reveals how Kuiper Belt objects form snowman shapes

Researchers at Michigan State University have developed a computer simulation showing that gravitational collapse can naturally produce double-lobed, snowman-like structures in the outer solar system. These contact binaries make up about 10 percent of planetesimals in the Kuiper Belt beyond Neptune. The findings, published in the Monthly Notices of the Royal Astronomical Society, explain a long-standing puzzle in astronomy.
