Building a New Planet
Science Update
Astronomers over the past decade have made remarkable progress in the study of extrasolar planets; over 500 distant worlds are now confirmed.

Dissolving star systems creates a mess in Orion
News Release: www.phys.org
"For young stars, stellar outflows are the rule. T Tauri stars and other young stars eject matter in generally collimated jets. However, a region in Orion's giant molecular cloud known as the Becklin-Neugebauer/Kleinmann-Low (BN/KL) region, appears to have a clumpy, scattered set of outflows with "finger-like" projections in numerous directions. A new study, led by Luis Zapata at the National Autonomous University of Mexico, explores this odd region."

Lensed Galaxies
Science Update
Just as a glass lens can deform the appearance of objects seen through it, so can the mass of the intervening galaxy can act as a "gravitational lens," distorting the image we would otherwise see into a more complex shape.

Making Massive Stars
Science Update
Massive stars -- those with more than about eight times the mass of the sun -- are arguably the most important actors in the universe.

Submillimeter Galaxies
Science Update
Astronomers using new submillimeter wavelength telescopes discovered, about dozen years ago, the existence of a new class of very distant galaxies.

Volcanic Moon of Jupiter Is Smelly and Bizarre
News Release: www.space.com article by Clara Moskowitz
"Jupiter's moon Io is one of the strangest places in our solar system, with extremely tall mountains, foul-smelling gases in its tenuous atmosphere and incredible levels of volcanic activity beneath its surface."

Astronomers Witness a Star Being Born
News Release: Yale University
"The study's authors -- who include astronomers from Yale University, the Harvard-Smithsonian Center for Astrophysics and the Max Planck Institute for Astronomy in Germany -- found the object using the Submillimeter Array in Hawaii and the Spitzer Space Telescope. Known as L1448-IRS2E, it's located in the Perseus star-forming region, about 800 light years away within our Milky Way galaxy."

The Atmosphere of Io
Science Update
Io is one of the four moons of Jupiter that Galileo discovered after he turned his new telescope heavenward.
June 4, 2010
Bok Globules
Science Update
Bok globules are small interstellar clouds of very cold gas and dust that are so thick they are nearly totally opaque to visible light, although they can be studied with infrared and radio techniques.
May 20, 2010
The Far Infrared Galaxy
Science Update
Our Milky Way galaxy, like other spiral galaxies, has copious amounts of dust in its spiral arms.

Seeing the Invisible
Science Update
Astronomers, like physicians, use as much of the electromagnetic spectrum as they can, from X-ray to radio wavelengths, to examine their subjects the with the most suitable diagnostics.

Intense Star Formation in the Early Universe
Science Update
Distant galaxies are not only far away in space. Because it takes time for their light to reach us, they are also very far away in time -- snapshots from the distant past.

Astronomers Get Sharpest View Ever of Star Factories in Distant Universe
News Release
Astronomers have combined a natural gravitational lens and a sophisticated telescope array to get the sharpest view ever of "star factories" in a galaxy over 10 billion light-years from Earth. They found that the distant galaxy, known as SMM J2135-0102, is making new stars 250 times faster than our Galaxy, the Milky Way.

Martian Weather
Science Update
The Mars Global Surveyor (MGS) is a NASA mission that arrived at Mars in September, 1997, and for nine years circled the planet every two hours in a polar orbit (that is, traveling from the north pole to the south pole and back) at an altitude of 400 kilometers (249 miles) above the Martian surface.

Simulating the Birth of Massive Stars
Science Update
Astronomers have made great strides recently in understanding how modest stars -- those like the sun or smaller -- are formed.
