Latest Smithsonian Astrophysical Observatory Stories
Long predicted by theory, the Smithsonian's Submillimeter Array has found the first conclusive evidence of an hourglass-shaped magnetic field in a star formation region. Measurements indicate that material in the interstellar cloud is dense enough to allow it to gravitationally collapse, warping the magnetic field in the process.
Sibling rivalry is alive and well in outer space. The Milky Way galaxy has two sister spirals competing for attention from photographers. The Andromeda galaxy usually wins the contest, posing frequently for cosmic portraits.
Astronomers using the MMT Observatory in Arizona have discovered two stars exiled from the Milky Way galaxy. Those stars are racing out of the Galaxy at speeds of more than 1 million miles per hour - so fast that they will never return.
While examining a region where new stars are forming with NASA's Spitzer Space Telescope, astronomers found a surprise - an object that looks like a giant tornado in space.
In an exercise that demonstrates the power of a multiwavelength investigation using diverse facilities, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have deciphered the true nature of a mysterious object hiding inside a dark cosmic cloud.
The U.S. could be in for quite a show tonight! Astronomers are predicting that the Northern Lights will shine on and off, periodically coating the northern sky in brilliant greens and reds.
Astronomers find jets everywhere when they look into space. Small jets spout from newborn stars, while huge jets blast out of the centers of galaxies. Yet despite their commonness, the processes that drive them remain shrouded in mystery.
The Submillimeter Array (SMA) has opened a new window onto the cosmos by observing radiation from some of the coldest, dustiest, and most distant objects in the universe.
Using the MMT Observatory in Tucson, AZ, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) are the first to report the discovery of a star leaving our galaxy, speeding along at over 1.5 million miles per hour.
The Harvard-Smithsonian Center for Astrophysics (CfA) has taken a key step toward the goal of building and operating a large next-generation telescope through its participation in the joint Giant Magellan Telescope (GMT). The GMT will have a diameter of about 83 feet (25.4 meters), about as wide as the 2004 Christmas tree in Rockefeller Center, New York, is tall.
