Kilonova gravitational-wave captured

For the first time, NASA scientists have detected light tied to a gravitational-wave event as two neutron stars merged in the galaxy NGC 4993, located about 130-million light-years from Earth in the constellation Hydra. On 27 August 2017, the space agency’s Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from a powerful […]

Scientists are another step closer to figuring out dark matter

  “Dark matter is an enigma we have long sought to unravel,” said John Grunsfeld, assistant administrator of NASA’s Science Mission Directorate in Washington. “With the combined capabilities of these great observatories, both in extended mission, we are ever closer to understanding this cosmic phenomenon.” Using observations from NASA’s Hubble Space Telescope and Chandra X-ray […]

Turbulence may prevent the formation of a large numbers of stars

  The same phenomenon that causes a bumpy airplane ride, turbulence, may be the solution to a long-standing mystery about the birth of stars, or the absence of it. This is the finding of  a new study using data from NASA’s Chandra X-ray Observatory. Galaxy clusters are the largest objects in the universe, held together […]

Chandra X-ray observatory celebrates 15 years in space

  Fifteen years ago, NASA’s Chandra X-ray Observatory was launched into space aboard the space shuttle Columbia. Since its deployment on 23 July  1999 Chandra has helped revolutionise the understanding of the universe through its unrivalled X-ray vision. Chandra, along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray […]

Hardy star survives supernova blast

  Chandra’s X-ray data also show that the inside of the supernova remnant is rich in oxygen, neon and magnesium, and optical observations with the South African Astronomical Observatory’s 1,9 m telescope show that the velocity of the massive star is changing and that it orbits around the neutron star or black  black hole with a period of tens of days.
