Uncovering the Secrets of Rocky Planets: NASA’s James Webb Telescope Strikes Again!
The NASA James Webb Space Telescope possesses unparalleled abilities to observe deep space beyond our galaxy, reaching back almost to the moment of the Big Bang. A recent study conducted by the eXtreme Ultraviolet Environments (XUE) program has made surprising discoveries regarding the presence of water and other molecules in the areas where rocky planets are formed, even under extreme environmental circumstances. These findings have astonished researchers and have called into question previous theories regarding the origins of rocky planets.

The eXtreme Ultraviolet Environments (XUE) James Webb Space Telescope program studied the protoplanetary disk, also known as massive star-forming regions, where environmental conditions are extreme, according to a NASA report. The study revealed that the region is responsible for the formation of various planetary systems, as well as how exoplanets are created.
The study examined 15 discs spread across three different regions in the Lobster Nebula, also known as NGC 6357, located 5,500 light-years from Earth in the constellation Scorpius. The Lobster Nebula is host to several massive stars in our galaxy that emit enormous amounts of ultraviolet (UV) radiation. Now, the James Webb Space Telescope will allow scientists to study “the effect of UV radiation on the rocky inner planets that form regions of protoplanetary disks around stars like our Sun,” NASA said.
The goal of the XUE program is to study the physical properties and chemical composition of a rocky planet in the Lobster Nebula using Webb’s Mid-Infrared Instrument (MIRI) Medium Resolution Spectrometer. Arjan Bik from Stockholm University in Sweden said: “Only the MIRI wavelength range and spectral resolution allow us to study the molecular reservoir of warm gas and dust and the physical conditions under which rocky planets form.”
The research focused on a protoplanetary disk called XUE 1, which is suspected to be exposed to large amounts of ultraviolet radiation. However, even after the extreme conditions, scientists have identified a diverse set of molecules that are crucial to the formation of rocky planets. This new discovery may change the various theories revolving around the formation of these rocky planets.
