The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has released a first look at the unprecedented data it will collect when science operations begin later this year. The satellite’s science team released a snapshot of a cluster of hundreds of galaxies and a spectrum of stellar wreckage in a neighboring galaxy, which gives scientists […]
Nearly two years ago in the early morning hours of Dec. 25, NASA’s James Webb Space Telescope successfully took flight from the jungle-encircled ELA-3 launch complex at Europe’s Spaceport near Kourou, French Guiana. Following a successful deployment in space, and the precise alignment of the telescope’s mirrors and instruments, Webb began science operations nearly six […]
This photo of Saturn was taken by NASA’s Hubble Space Telescope on October 22, 2023, when the ringed planet was approximately 850 million miles from Earth. Hubble’s ultra-sharp vision reveals a phenomenon called ring spokes. Saturn’s spokes are transient features that rotate along with the rings. Their ghostly appearance only persists for two or three […]
The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA’s Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. “The bright, steady gamma-ray glow of the Milky Way […]
On a vast ice sheet in Antarctica, scientists and engineers are preparing a NASA experiment called GUSTO to explore the universe on a balloon. GUSTO will launch from the Ross Ice Shelf, near the U.S. National Science Foundation’s McMurdo Station research base, no earlier than Dec. 21. GUSTO, which stands for Galactic/Extragalactic ULDB Spectroscopic Terahertz […]
