CSI: Cosmic Scene Investigation—How a Star’s Death Is Still Shaping the Universe

March 29, 2025

The incredibly distant galaxy JADES-GS-z13-1, observed just 330 million years after the big bang, was initially discovered with deep imaging from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera). Now, an international team of astronomers definitively has identified powerful hydrogen emission from this galaxy at an unexpectedly early period in the universe’s history. JADES-GS-z-13 has a redshift (z) of 13, which is an indication of its age and distance.

This artist’s concept visualizes a super-Neptune world orbiting a low-mass star near the center of our Milky Way galaxy. Scientists recently discovered such a system that may break the current record for fastest exoplanet system, traveling at least 1.2 million miles per hour, or 540 kilometers per second.

This is an 80-million-pixel picture of the star cluster RCW 38, located 5500 light-years away in the constellation Vela. RCW 38 is a young cluster containing about 2000 stars, and is bursting with star-forming activity. The picture was taken with ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), operating in Chile's Atacama Desert. It shows a mixture of gas, dust and stars, creating an extravagant, yet spectacular landscape. As VISTA observes infrared light, it is able to peer through most of the dust in this region, which would block our view when observing in visible light. Behind the dust, VISTA is showing young stars within dusty cocoons and cold 'failed' stars known as brown dwarfs, thus revealing the secrets within these young stellar nurseries.
