Scientists discover CO2 and CO ices in outskirts of solar system

A research team led by UCF's Mário Nascimento De Prá and Noemí Pinilla-Alonso discovered carbon dioxide and carbon monoxide ices on 59 trans-Neptunian objects using the James Webb Space Telescope. The findings suggest that carbon dioxide was abundant in the protoplanetary disk, while the origin of carbon monoxide remains uncertain.

Webb cracks case of inflated exoplanet

The James Webb Space Telescope has provided new insights into the mysterious case of WASP-107 b, an exoplanet that defies explanation due to its inflated size. Data collected by Webb shows surprisingly little methane in the planet's atmosphere, indicating a significantly hotter interior and core mass than previously estimated.

Jumbo discovery: astronomers offer new model for formation of recently discovered “free-floating” planets

Researchers introduce a new model that suggests dense stellar clusters can eject pairs of giant planets, which remain gravitationally bound to each other as they float through space. This discovery fills a critical gap in our understanding of planetary evolution and challenges prevailing theories of planet formation.

Hubble goes hunting for small main belt asteroids

The study used a trove of archived Hubble images to identify the asteroids, working with citizen scientists and machine learning algorithms. The discovery provides insights into the formation and evolution of the asteroid belt, suggesting that smaller fragments may be remnants of larger asteroids that have collided.
