Middleweight Black Hole: Swift, XMM-Newton Satellites Tune Into X-ray Source
Impact Lab —
Authority: 519
Swift X-ray observations of galaxy NGC 5408 indicate its ultraluminous X-ray source undergoes periodic changes every 115.5 days.While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers at ...10 hours ago -

WASHINGTON, D.C. — Astronomers have for the first time traced gamma rays, the most energetic form of light, to galaxies undergoing a frenzy of star birth. The finding, which has revealed a new class of galactic gamma-ray sources, is not unexpected. But it provides new hints about the origin of many cosmic rays , ...1 week ago -
What gives a blackhole its strong gravitational pull?

Authority: 165
Every gravitational pull has a "heart" in a sense. For instance, the heart of the gravitational pull of the sun is the sun. The sun generates its own gravitational pull. Well, it would take something UNBELIEVEABLY massive to generate a gravitational pull so massive that not even light could escape - exactly what a ...1 week ago -

The Swift Gamma Ray Observatory was designed to catch GRBs "on the fly." Power source of these immense explosions has been considered a mystery. Light from GRB 090423 reached Earth on April 23. This Gamma Ray burst is estimated to have exploded 13 billion years ago, making it a candidate for the oldest object ever ...1 week ago -

In September, 2008, the CERN Large Hadron Collider was slated to fully power up, but there were glitches that have stalled (until November of 2009) its search for the Higgs boson (the particle/field responsible for making mass, and thus matter, possible). But before the first attempt by CERN to go “full throttle ...2 weeks ago -
