Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary

Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world.

Hubble Examines an Active Galaxy Near the Lion’s Heart

It might appear featureless and unexciting at first glance, but NASA/ESA Hubble Space Telescope observations of this elliptical galaxy — known as Messier 105 — show that the stars near the galaxy’s center are moving very rapidly. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of […]

NASA’s Roman Mission Gets Cosmic ‘Sneak Peek’ From Supercomputers

Researchers are diving into a synthetic universe to help us better understand the real one. Using supercomputers at the U.S. DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images depicting the cosmos as NASA’s Nancy Grace Roman Space Telescope and the Vera C.

NASA’s Webb Opens New Window on Supernova Science

Peering deeply into the cosmos, NASA’s James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few […]

‘Super’ Star Cluster Shines in New Look From NASA’s Chandra

Westerlund 1 is the biggest and closest “super” star cluster to Earth. New data from NASA’s Chandra X-ray Observatory, in combination with other NASA telescopes, is helping astronomers delve deeper into this galactic factory where stars are vigorously being produced.

Webb Spots a Starburst

The James Webb Space Telescope observed “starburst” galaxy NGC 4449, seen in this image released on May 29, 2024. Starbursts are intense periods of star formation usually concentrated at a galaxy’s core, but NGC 4449’s activity is much more widespread — likely due to past interactions with its galactic neighbors.

Galaxies Actively Forming in Early Universe Caught Feeding on Cold Gas

Researchers analyzing data from NASA’s James Webb Space Telescope have pinpointed three galaxies that may be actively forming when the universe was only 400 to 600 million years old. Webb’s data shows these galaxies are surrounded by gas that the researchers suspect to be almost purely hydrogen and helium, the earliest elements to exist in […]

Spotted: ‘Death Star’ Black Holes in Action

A team of astronomers have studied 16 supermassive black holes that are firing powerful beams into space, to track where these beams, or jets, are pointing now and where they were aimed in the past, as reported in our latest press release. Using NASA’s Chandra X-ray Observatory and the U.S.

NASA Images Help Explain Eating Habits of Massive Black Hole

Data from NASA’s retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others. In images from NASA’s retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy.

These images show evidence for an exhaust vent attached to a chimney releasing hot gas from a region around the supermassive black hole at the center of the Milky Way, as reported in our latest press release.
