Data recorded by NASA’s Chandra X-ray Observatory of a neutron star as it passed through a dense patch of stellar wind emanating from its massive…
Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA’s Chandra X-ray Observatory they have…
Most galaxies host supermassive black holes at their nuclei, each with millions or billions of solar-masses of material. There is thought to be a torus…
This is the season of celebrating, and the Chandra X-ray Center has prepared a platter of cosmic treats from NASA’s Chandra X-ray Observatory to enjoy. This selection…
Before electrical power became available, water fountains worked by relying on gravity to channel water from a higher elevation to a lower one. This water…
3C196.1 is a massive elliptical galaxy, the brightest member of a cluster of galaxies about three billion light-years away that is notable for its strong…
Astronomers have detected a bright X-ray outburst from a star in the Small Magellanic Cloud, a nearby galaxy almost 200,000 light years from Earth. A…
Scientists have confirmed the identity of the youngest known pulsar in the Milky Way galaxy using data from NASA’s Chandra X-ray Observatory. This result could…
The cause of Chandra’s safe mode on October 10 has now been understood and the Operations team has successfully returned the spacecraft to its normal…
NASA has awarded a contract extension to the Smithsonian Astrophysical Observatory (SAO) in Cambridge, Massachusetts, to continue operations and science support for the agency’s Chandra…
Stars frequently form in crowded environments. By combining the resources of multi-wavelength missions like Chandra in the X-ray and Spitzer in the infrared, astronomers are…
Astronomers have used NASA’s Chandra X-ray Observatory to discover a ring of black holes or neutron stars in a galaxy 300 million light years from…
Scientists have taken major steps in their hunt to find black holes that are neither very small nor extremely large. Finding these elusive intermediate-mass black…
Chandra data indicates that a young star, known as RW Aur A, has likely destroyed and consumed an infant planet. If confirmed, this would be…
A binary star system is one that contains a pair of stars orbiting each other. A black hole X-ray binary is a binary system in…
The central black holes may be the driving force in how much star formation occurs in a certain type of rare galaxy. ‘Red nuggets’ are…
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of…
