The capture you see above shows WR 124, a star located in the constellation Sagittarius, approximately 15,000 light years away from Earth. When the JWST first sighted WR 124 in June 2022, it captured the star undergoing a Wolf-Rayet phase. According to NASA, only some massive stars go through such a transition before they eventually explode. Those that do are among the largest and most luminous celestial bodies in the night sky. In the case of WR 124, NASA estimates the star is 30 times the mass of the Sun and has so far shed about 10 Suns worth of material. Over time, the gas Wolf-Rayet stars expel will cool and form cosmic dust.<\/p>\n<div id=\"dd0ac156baf8449b9ebce85405e2bec5\">\n<blockquote class=\"twitter-tweet\">\n<p lang=\"en\" dir=\"ltr\">There is beauty in transience. \ud83c\udf38<\/p>\n<p>Webb\u2019s stunning image of a super bright, massive Wolf-Rayet star calls forth the ephemeral nature of cherry blossoms.

The material is an essential building block of the universe. As NASA notes, it shelters coalescing stars and can even come together to form planets. At the moment, however, there\u2019s no theory that explains the amount of cosmic dust there is in the universe. The JWST could help astronomers tackle that mystery. \u201cBefore Webb, dust-loving astronomers simply did not have enough detailed information to explore questions of dust production in environments like WR 124, and whether the dust grains were large and bountiful enough to survive the supernova and become a significant contribution to the overall dust budget,\u201d NASA said. \u201cNow those questions can be investigated with real data.\u201d<\/p>\n<p><span id=\"end-legacy-contents\"><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>NASA has shared an image from the James Webb Space Telescope that could help astronomers one day answer longstanding questions about our universe.
