A star called KIC 8462852 has been in the news recently for unexplained and bizarre behavior.
A new study publishing this week in the Astrophysical Journal by Gary Przeau of NASA's Jet Propulsion Laboratory proposes the existence of long filaments of dark matter, or "hairs."
A way of estimating more accurate distances to the thousands of so-called planetary nebulae dispersed across our galaxy has been announced.
Our Sun is a relatively quiet star that only occasionally releases solar flares or blasts of energetic particles that threaten satellites and power grids.
Just counting the number of galaxies in a patch of sky provides a way to test astronomers' theories of galaxy formation and evolution.
Astronomers at Yale and Harvard have found a galaxy with a heartbeat -- and they've taken its pulse.
Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.
The remains of a fatal interaction between a dead star and its asteroid supper have been studied in detail for the first time by an international team of astronomers using the Very Large Telescope at ESOs Paranal Observatory in Chile.
An enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists Jonathan Squire and Amitava Bhattacharjee at the U.S. Department of Energy's Princeton Plasma Physics Laborator have found a clue to the answer in the collective behavior of small magnetic disturbances.
A new space telescope will soon peer into the darkness of 'near space' (within a few thousand light years of Earth) to seek answers related to the field of high-energy astrophysics
A team of astronomers working at the National Centre for Radio Astrophysics have discovered, using the Giant Metrewave Radio Telescope, an extremely rare galaxy of gigantic size.
NASA's Swift spacecraft has detected its 1,000th gamma-ray burst (GRB). GRBs are the most powerful explosions in the universe, typically associated with the collapse of a massive star and the birth of a black hole.
Using NASA's Hubble Space Telescope to conduct a "cosmic archaeological dig" at the very heart of our Milky Way galaxy, astronomers have uncovered the blueprints of our galaxy's early construction phase.
Two stars shine through the center of a ring of cascading dust in this image taken by the NASA/ESA Hubble Space Telescope.
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory.
Using a sample of 4,700 blue horizontal-branch stars from the Sloan Digital Sky Survey, the research team showed that the oldest stars are concentrated in the central region of the galaxy, confirming predictions from numerical simulations of galaxy assembly.
The Vista Variables in the Va Lctea Survey (VVV) ESO public survey is using the VISTA telescope at the Paranal Observatory to take multiple images at different times of the central parts of the galaxy at infrared wavelengths.
