Giant Cosmic Cotton Ball: A Dark Matter Deficient Galaxy
The galaxy NGC 1052-DF2 resides in a field of galaxies about sixty-five million light-years away. Its low mass, only about two hundred million solar-masses, makes…

Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner…
When a fast solar wind stream erupts from a coronal hole (a cooler region in the Sun’s atmosphere) and overtakes a slower moving solar wind…
Most stars including the Sun generate magnetic activity that drives a fast-moving, ionized wind and also produces X-ray and ultraviolet emission (often referred to as…
Gigantic cavity in space sheds new light on how stars form. Astronomers analyzing 3D maps of the shapes and sizes of nearby molecular clouds have…
Magnetic fields in space are sometimes called the last piece in the puzzle of star formation. They are much harder to measure than the masses…
New high-resolution observations clearly show a moon-forming region around exoplanet PDS 70c. The observations have allowed astronomers to determine the ring-shaped region’s size and mass…
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…
In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the icy snowball traveled 110,000 miles per…
Astronomers spotted an unusual set of rings in X-rays around a black hole with a companion star. These rings are created by light echoes, a…
Abell 1775 is a system where a smaller galaxy cluster has plowed into a larger one. Using X-rays from Chandra and data from other telescopes…
The ionization of the neutral gas in an interstellar molecular cloud plays a key role in the cloud’s evolution, helping to regulate the heating and…
The star Betelgeuse became visibly darker in 2019 and 2020, puzzling astronomers; new images show that the star was partially concealed by a cloud of…
The long relationships between stars and the planets around them — including the Sun and the Earth — may be even more complex than previously…
How do flares, or outbursts, from young stars affect planets that orbit around them? The largest study of star-forming regions in X-rays using NASA’s Chandra…
Nearly 40 years after creating the first, iconic map of the universe, researchers aim for the largest map ever. In 1983, astrophysicists at the Center…
A new panorama provides an unprecedented X-ray view above and below the center of the Milky Way. This new survey builds on previous Chandra observations,…
How hospitable are red dwarf stars, the most common and long-lasting stars in our Galaxy? Researchers used Chandra and Hubble data to look at the…
