Milky Way bigger than thought
Our own Milky Way galaxy, long considered a “little sister” to the larger Andromeda Galaxy, is all grown-up, according to new research. The findings, presented at a Jan. 5 meeting of the American Astronomical Society in Long Beach, Calif., by Harvard-Smithsonian Center for Astrophysics (CfA) researchers, show that the galaxy has about 50 percent more…

Solar system’s twin has two asteroid belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three…

Black holes are the heart of galaxies
Astronomers think that many — perhaps all — galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form.…

Interdisciplinary conference takes micro, macro look at origins of life
How did we get here? That’s not the first line in a hangover joke. It’s a question that has been asked for centuries about the origins of life on Earth. At Harvard last week, an A-list of astronomers, physicists, Earth scientists, and chemists met in the Radcliffe Gymnasium to look at this and other fundamental…

White dwarf “sibling rivalry” explodes
The new find, supernova 2006gz, was classified as a Type Ia due to the lack of hydrogen and other characteristics. However, an analysis combining CfA data with measurements from The Ohio State University suggested that SN 2006gz was unusual and deserved a closer look.

The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are two of the Milky Way’s closest neighboring galaxies. A stunning sight in the southern hemisphere, they were named after the Portuguese explorer Ferdinand Magellan, who explored those waters in the 16th century. For hundreds of years, these galaxies were considered satellites of the Milky…

For the first time, astronomers have created a rough map of a planet orbiting a distant sun-like star, employing a technique that may one day enable mapping of Earth-like worlds. Because the planet just charted is a gas giant and lacks a solid surface, the map shows cloud-top features. Using the Spitzer infrared space telescope,…
