Some 30,000 light-years from the center of the Milky Way, a cosmic message jolted Gwen Bell from bed: The Ulsa Minor and Sculptor galaxies are repelling each other. Realizing that she had drawn her vectors wrong, Bell flipped on her computer and began to finally make some headway on the problem that had stumped her for weeks.

Large balls of gas--failed stars that glow faintly like dying embers--are a newly discovered class of stellar objects and may be the most common bodies in the Milky Way, Caltech astronomers reported Tuesday at a San Diego meeting of the American Astronomical Society. They call the new objects "L" dwarfs and said their discovery will force revision of a century-old system of classifying stars based on chemistry and temperature. J.

From Earth, the Milky Way is a band of stars that lights up the night sky. From outside the galaxy looking in, astronomers say, it's an entirely different picture. Astronomers say a bar of stars cuts through the center of the galaxy that includes the sun and Earth. "We're pretty certain of the extent and orientation of this bar because we got more data than anybody else ... by a long shot," said Edward G.

UC San Diego scientists have discovered a second huge source of gamma rays in the Milky Way, a black hole or a neutron star that is generating enough radiation to power 50,000 suns. Reporting to the American Astronomical Society meeting in Seattle, research physicist Michael S. Briggs said the object is about 1,800 light-years away from Earth. This is much closer than the so-called "Great Annihilator," the gamma ray source that is believed to be a black hole near the center of the galaxy.

An astronomer has found "irrefutable evidence" of at least two planets orbiting a nearby star--the first confirmed observation of planets outside the solar system humanity calls home. What has scientists most excited, however, is that the finding suggests that planets can form around almost any star and that the galaxy may well be crowded with planets.

Dozens of massive stars, destined for short but brilliant lives, were born less than a light-year from the Milky Way's central black hole, one of the most hostile environments in our galaxy, astronomers reported Thursday. Researchers using the orbiting Chandra X-ray Observatory and other instruments believe there is a safe zone around black holes, a big dust ring where stars can form.

Astronomers studying photographs of the sky said Monday that the Milky Way apparently is shrouded by enough invisible "dark matter" to make Earth's home galaxy five to 10 times larger and heavier than once thought. UC Santa Cruz astronomer Douglas N.C. Lin said the Milky Way is so massive that it is swallowing up the smaller, neighboring galaxy known as the Large Magellanic Cloud.

Snapping the most detailed images yet of the center of the Milky Way, astronomers have captured their first glimpses of the day-to-day life of the monstrous black hole residing at our galaxy's core. They reveal a temperamental and somewhat wimpy beast that appears to be starving. Black holes -- space and time twisters that personify the extremes of physics -- are among the most mysterious objects in the universe. Our neighborhood black hole is no exception.

A new study of some of the Milky Way's oldest stars deepens the riddle of the age of the universe. The study suggests that the stars are at least 9.5 billion years old, meaning that our galaxy and indeed the universe cannot be any younger than that. Some estimates of how the cosmos has expanded since the "big bang" suggest that the universe was created as recently as 8 billion years ago.

After 16 years of research, teams of American and European scientists have compiled the most complete portrait of the gigantic black hole at the center of the Milky Way, plotting its gravity-bending mass as being equivalent to a staggering 4 million suns. The researchers from Germany and UCLA also pinpoint the distance to the center of the galaxy at 27,000 light-years.
