NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009.

The brightly glowing plumes seen in this image are reminiscent of an underwater scene, with turquoise-tinted currents and nebulous strands reaching out into the surroundings.
Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.
It was 45 years ago when astronomer Klim Churyumov and Svetlana Gerasimenko, one of his researchers, unwittingly began a new chapter in the history of space exploration.
Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away.
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame.
Space scientists at the University of Leicester have detected a curious signal in the X-ray sky -- one that provides a tantalizing insight into the nature of mysterious 'dark matter.'
A group of researchers led by Melina Bersten of Kavli IPMU recently presented a model that provides the first characterization of the progenitor for a hydrogen-deficient supernova.
Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.
This magnificent new image taken with the NASA/ESA Hubble Space Telescope shows the edge-on spiral galaxy NGC 4206, located about 70 million light-years away from Earth in the constellation of Virgo.
Astronomers have discovered a black hole that is consuming gas from a nearby star 10 times faster than previously thought possible.
Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded.
On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded.
Certain primordial stars--those between 55,000 and 56,000 times the mass of our Sun, or solar masses--may have died unusually. In death, these objects--among the Universe's first-generation of stars--would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
Astronomers usually have to peer very far into the distance to see back in time and view the universe as it was when it was young.
The Balloon Observation Platform for Planetary Science (BOPPS) is a high-altitude, stratospheric balloon mission that is planned for launch today to study a number of objects in our solar system, including an Oort cloud comet.
New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up.
Scientists of the Planck collaboration, and in particular the Trieste team, have conducted a series of in-depth checks on the discovery recently publicized by the BICEP2 project (the Antarctic observatory)
