Strange ‘sonic boom’ accompanied unprecedented event. Mysterious X-rays observed 3.5 years after the merger of two neutron stars Astrophysicists believe a kilonova afterglow or materials…
Results narrow in on what powers new class of supernovae. Another member of the new “Cow” class of supernova explosions has been discovered—the brightest one…
A new gallery of images combining X-ray data from Chandra with those from other telescopes is being released. The objects range from a supernova remnant…
The discovery of a supermassive black hole in a relatively small galaxy could help astronomers unravel the mystery surrounding how the very biggest black holes…
Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA’s Chandra X-ray Observatory. This unusual set of features…
Astronomers have discovered a supermassive black hole in the dwarf galaxy Mrk 462 with NASA’s Chandra X-ray Observatory. The percentage of these galaxies that have…
About 400,000 years after the universe was created began a period called “The Epoch of Reionization.” During this time, the once hotter universe began to…
Four cavities in the hot gas of a single galaxy cluster have been found. Astronomers found this quartet of X-ray cavities in the cluster located…
An exhausted star still has some punches to deliver. Astronomers have found that a white dwarf is pummeling a companion object — either a lightweight…
A white dwarf is blasting a companion object, which is either a low-mass star or a planet. The companion is likely receiving a barrage of…
Using ESA’s XMM-Newton and NASA’s Chandra X-ray space telescopes, astronomers have made an important step in the quest to find a planet outside of the…
Until now, astronomers have found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all less than about 3,000 light-years from…
The supernova remnant G344.7-0.1 is across the Milky Way about 19,600 light-years from Earth. It belongs to a class of supernovas called “Type Ia” that…
Astronomers have announced evidence for a possible planet in another galaxy. This “exoplanet” would be much farther away than any of the thousands of others…
Since 2020, a “sonification” project has transformed astronomical data from some of the world’s most powerful telescopes into sound. Three new objects — a star-forming…
By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early…
Astronomers have used an “X-ray magnifying glass” to study a black hole system in the early Universe. The amplification and magnification of light by an…
