NASA'S Spitzer Finds Water Vapor on Hot, Alien Planet

Robert Tindol
The exoplanet HD 189733b has just been found to have water vapor in its atmosphere. The observation provides the best evidence to date that water exists on worlds outside our own solar system.

Astronomers Claim to Find the Most Distant Known Galaxies

Jill Perry
Using natural "gravitational lenses," an international team of astronomers claim to have found the first traces of a population of the most distant galaxies yet seen-the light we see from them today left more than 13 billion years ago, when the universe was just 500 million years old.

Caltech Scientists Create Breakthrough Sensor Capable of Detecting Individual Molecules

Robert Tindol
Applied physicists at the California Institute of Technology have figured out a way to detect single biological molecules with a microscopic optical device. The method has already proven effective for detecting the signaling proteins called cytokines that indicate the function of the immune system, and it could be used in numerous medical applications, such as the extremely early detection of cancer and other diseases, as well as in basic biological research.

Ooguri Appointed Fred Kavli Professor of Theoretical Physics

John Avery
Like many Japanese schoolchildren, Hirosi Ooguri read about the physicist Hideki Yukawa, who became Japan's first Nobel laureate in 1949 for predicting the existence of mesons, elementary particles that hold atomic nuclei together. Ooguri says, "I was very impressed by the power of mathematics in discovering how the universe works."

The Dwarf Planet Known as Eris is More Massive than Pluto, New Data Shows

Robert Tindol
Die-hard Pluto fans still seeking redemption for their demoted planet have cause for despair this week. New data shows that the dwarf planet Eris is 27 percent more massive than Pluto, thereby strengthening the decree last year that there are eight planets in the solar system and a growing list of dwarf planets.

On-Chip Optics Makes Continuous Visible Light from Low-Power Infrared

John Avery
If you shine a red laser pointer through a glass window you wouldn't expect it to come out blue on the other side, but with a much brighter beam it just might. At high intensities light energy tends to combine and redistribute, so that red light really can produce blue.

Astronomers Find Their Third Planet With Novel Telescope Network

Robert Tindol
Astronomers using the Trans-atlantic Exoplanet Survey (TrES) network of small telescopes are announcing today their discovery of a planet twice the mass of Jupiter that passes in front of its star every 31 hours. The planet is in the constellation Hercules and has been named TrES-3 as the third planet found with the TrES network.

Running Rings Around the Galaxy

Robert Tindol

An astronomer at the California Institute of Technology has discovered three giant stellar streams arcing high over the Milky Way. Remnants of cannibalized galaxies and star clusters, the streams are between 13,000 and 130,000 light-years distant from Earth and extend over much of the northern sky. The new results are being presented by Carl Grillmair at this week's meeting of the American Astronomical Society in Honolulu, Hawaii.

Newly Discovered Olympian Galaxy Will Provide Fresh Insights into Galactic Formation

Kathy Svitil
A newly discovered dwarf galaxy in our local group has been found to have formed in a region of space far from our own and is falling into our system for the first time in its history.
