The NASA/ESA Hubble Space
Telescope has taken a
picture of the barred spiral
galaxy NGC 1073, which is

Do Black Holes Help Stars Form?
The center of just about
every galaxy is thought to
host a black hole, some with
masses of thousands of
millions of Suns and
consequently strong
gravitational pulls that

How Star-Forming Galaxies Evolve Into 'Red and Dead' Elliptical Galaxies
January 11, 2012 — Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into 'red and dead' elliptical galaxies, catching a large group of ... > full story -
Hubble Zooms in on Double Nucleus in Andromeda Galaxy
January 11, 2012 — A new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy, the only galaxy outside the Milky Way ... > full story -
Astronomers Pinpoint Launch of 'Bullets' in a Black Hole's Jet
January 10, 2012 — Astronomers have identified the moment when a black hole in our galaxy launched super-fast knots of gas into space. Racing outward at about one-quarter the speed of light, these "bullets" of ionized ... > full storyMore: -
2012: Fear No Supernova
December 28, 2011 — Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in ... > full story -
2012: Shadow of the Dark Rift
December 28, 2011 — One of the most bizarre theories about 2012 has built up with very little attention to facts. This idea holds that a cosmic alignment of the sun, Earth, the center of our galaxy -- or perhaps the ... > full story -
Detecting the 'Heartbeat' of Smallest Black Hole Candidate
December 15, 2011 — Astronomers have identified a candidate for the smallest-known black hole using data from NASA's Rossi X-ray Timing Explorer (RXTE). The evidence comes from a specific type of X-ray pattern, ... > full story -
Disaster Looms for Gas Cloud Falling Into Milky Way's Central Black Hole
December 14, 2011 — Astronomers have observed a cloud of gas several times the mass of Earth approaching the 4.3 million solar-mass black hole at the center of the Milky Way, and calculate that it will not survive the ... > full storyMore: -
Early Black Holes Grew Big Eating Cold, Fast Food
December 12, 2011 — Researchers have discovered what caused the rapid growth of early supermassive black holes -- a steady diet of cold, fast food. Computer simulations show that thin streams of cold gas flow ... > full story -
Record Massive Black Holes Discovered Lurking in Monster Galaxies
December 5, 2011 — Astronomers using the Keck, Gemini and MacDonald observatories have discovered the largest black holes to date: Two monsters with masses equivalent to 10 billion suns that are threatening to consume ... > full storyMore: -
