Looking Beyond: NASA's Frontier Fields Possibly Finds One of the Youngest Galaxies in the Early Universe

This image of the galaxy cluster Abell 2744 was obtained with NASA’s Hubble Space Telescope, as part of the Frontier Fields program, designed to push the limits of how far we can see into the early universe. The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy candidates [...]

NuSTAR Sheds New Light on Supernova Explosions

This is the first map of radioactivity in a supernova remnant, the blown-out bits and pieces of a massive star that exploded. The blue color shows radioactive material mapped in high-energy X-rays using NuSTAR. Heated, non-radioactive elements previously imaged by Chandra using low-energy X-rays are shown in red, yellow, and green. Image Credit/Caption: NASA/JPL-Caltech/CXC/SAO

Chandra Telescope Observes Impressive Pulsar Racing Away From Ancient Supernova

An extraordinary jet trailing behind a runaway pulsar is seen in this composite image that contains data from Chandra (purple), radio data from the ACTA (green), and optical data from the 2MASS survey (red, green, and blue). The pulsar—a spinning neutron star—and its tail are found in the lower right of this image. The [...]

NASA's Chandra Observatory Catches Giant Black Hole Rejecting Material

Astronomers using NASA’s Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

Chandra X-Ray Observatory Reveals 'Black Hole Bonanza' in Andromeda Galaxy

Data from Chandra’s X-ray Observatory has led astronomers to unveil 26 black holes in the Milky Way’s neighbor, the Andromeda Galaxy. This is the largest number of black hole candidates found in a galaxy outside our own. Image Credit: X-ray: NASA/CXC/SAO/R. Barnard, Z. Lee et al.; Optical: NOAO/AURA/NSF/REU Program/B. Schoening, V. Harvey and Descubre [...]

NASA'S Chandra Suggests Rare Explosion Created Our Galaxy’s Youngest Black Hole

Image Credit: NASA/CXC/NGST

WASHINGTON — New data from NASA’s Chandra X-ray Observatory suggest a highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy. The remnant appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a [...]

New Chandra Movie Features Neutron Star Action

WASHINGTON — Unlike with some blockbuster films, the sequel to a movie from NASA’s Chandra X-ray Observatory is better than the first. This latest movie features a deeper look [...]

How to Save a ‘Great Observatory’ - Step Three: Enter the Saviours

Twenty-one years ago, this week, five astronauts exchanged anxious glances aboard Space Shuttle Atlantis. In the pilots’ seats at the front of the flight deck were veterans Steve Nagel [...]

How to Save a ‘Great Observatory’: Step Two - Launch into Space

The Gamma Ray Observatory (GRO) is positioned for deployment from Atlantis, 21 years ago this week. The observatory's heart-stopping first few hours would ultimately give way to one of the greatest missions ever undertaken in space science. Photo Credit: NASA

With the Gamma Ray Observatory (GRO), NASA hoped to dispel some of the pessimism [...]
