NASA’s Webb Redefines Dividing Line Between Planets, Stars

Where is the dividing line between stars and the most massive planets? Scientists think it may depend on how they formed. Was it from a bottom-up approach, gradually growing larger over time, or a top-down approach in which a large collection of gas and dust fragments into smaller, planet-sized bits? To answer these questions, astronomers used the James Webb Space Telescope to study an object weighing about 15 times as much as Jupiter, which put…

Webb Redefines The Dividing Line Between Planets And Stars - Astrobiology

Planets, like those in our Solar System, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way. Astronomers used the James Webb Space Telescope to examine 29 Cygni b, an object […] The post Webb Redefines The Dividing Line Between Planets And Stars appeared first on Astrobiology.

NASA's Webb Telescope Redefines Planet-Star Boundary in New Findings

Astronomers Uncover Formation Secrets of 29 Cygni b Using James Webb Space Telescope Astronomers have made significant strides in understanding the formation of massive exoplanets, specifically 29 Cygni b, which is about 15 times the mass of Jupiter. Utilizing NASA’s James Webb Space Telescope, researchers revealed that this gas giant likely formed through a bottom-up […]
