There has been an unexpected discovery made by the James Web Space Telescope. In the main asteroid belt between Mars and Jupiter, it discovered water around a comet. This scientific achievement marks the first time that gas—in this case, water vapor—has been detected surrounding a comet. This could imply that water was frozen as ice in the main asteroid belt during the early solar system.
Michael Kelley documented
In the past, we’ve observed comet-like objects in the main belt, but only with this precise spectral data from the JWST can we say yes, it’s water ice that is producing that effect, according to Michael Kelley, an astronomer at the University of Maryland. He oversaw this study. According to Kelley, we can now show that water ice from the early solar system can be retained in the asteroid belt thanks to the JWST’s studies of Comet Read.
The discovery surrounding Come 238/Read may support beliefs that comets from outer space brought water to Earth. The most recent discovery is shrouded in mystery, though. Astronomers predicted that 238P/Read would not contain carbon dioxide.
Being in the asteroid belt for a long time may cause carbon dioxide to evaporate more readily than water ice and spread out across billions of years, according to Kelley. Another possibility might be that this comet formed in a region of the solar system without this chemical.
Stefanie Milam said
According to Stefanie Milam, “Our water-soaked world,” which is teaming with life and, as far as we know, unique in the universe, is somewhat of a mystery because we don’t know how all this water got there. She is a co-author of the study and the Webb Deputy Project Scientist for Planetary Science. She continued, Knowing the past of water distribution in the solar system will help us comprehend other planetary systems and determine whether they might eventually support an Earth-like planet.
The space telescope’s ability to observe the comet in amazing detail is a remarkable accomplishment. The team would search for comparable comets with similar compositions beyond Comet 238P/Read.
Statement by Heidi Hammel
These asteroid belt objects are small and faint, but thanks to the JWST, we can finally observe what’s going on with them and make some inferences, according to Heidi Hammel. She is a co-author of the study and an astronomer at the Universities for Research in Astronomy (AURA). Do other main belt comets also lack carbon dioxide, she added? It will be intriguing to find out in any case.
In-situ missions and additional observations with the James Web Space Telescope and other telescopes are being discussed. This might make it easier to get samples from comets in the main belt. It should be mentioned that the primary belt coming categorization is new. One of the three objects that helped construct this family of comets that are closer to Earth is Comet 238P/Read.
