Chandra Spots a Cosmic Amethyst in a Dying Star
Chandra has found a bubble of ultra-hot gas at the center of a planetary nebula. Planetary nebulas are formed when Sun-like stars run out of…

What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common? The answer is…
Some supermassive black holes launch powerful beams of material, or jets, away from them, while others do not. Astronomers may now have identified why. Using…
Humanity has “eyes” that can detect all different types of light through telescopes around the globe and a fleet of observatories in space. From radio…
Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process,…
Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million…
A new study reveals what happens when a supermassive black hole in the center of a galaxy cluster stops being active. By combining data from…
Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA’s Chandra X-ray…
For decades, astronomers have known about irregular outbursts from the double star system V745 Sco, which is located about 25,000 light-years from Earth. V745 Sco…
Astronomers have reported the first detection of X-rays from the earliest phase of evolution of a star like our Sun. This discovery from NASA’s Chandra…
A new study, based on data from ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, sheds new light on a three million light-year long bridge of…
Astronomers may have discovered a new kind of survival story: a star that had a brush with a giant black hole and lived to tell…
Astronomers used Chandra to perform a test of string theory, a possible “theory of everything” that would tie all of known physics together. One of…
Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray space observatories, along with radio telescopes on ground, have spotted the aftermath of the most powerful explosion…
The biggest explosion seen in the universe has been found. This record-breaking, gargantuan eruption came from a black hole in a distant galaxy cluster hundreds…
Orange Dwarf Stars Most Likely to Host Planets To date astronomers have discovered over 4,000 planets orbiting other stars. Statistically, there should be over 100…
Movie Dissects the Nebula’s Intricate Nested Structure In the year 1054 AD, Chinese sky watchers witnessed the sudden appearance of a “new star” in the…
One black hole is influencing the rate of star formation in multiple galaxies and across vast distances. This is a rare example of “positive feedback”…
