Dwarf Star Gulps Giant to Form Supernova

A team of European and American astronomers has announced the discovery of the best evidence yet for the nature of the star systems that explode as type Ia supernovae. The team obtained a unique set of observations with the European Southern Observatory's Very Large Telescope and the Keck I 10-meter telescope in Hawaii.

Caltech, JPL, Northrop Grumman to Celebrate 50 Years of Space Exploration

Before October 1957, space flight was a thing of fantasy. Today we are experienced space explorers with unlimited voyages to undertake. Where is space flight's next horizon? What constitutes sensible space investment? How did the space pioneers accomplish their goals? These topics will be addressed at "50 Years in Space: An International Aerospace Conference Celebrating 50 Years of Space Technology," which will take place from September 19 to 21 at the California Institute of Technology.

Astronomers Claim to Find the Most Distant Known Galaxies

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.

Pioneer of 20th-Century Mathematics John Todd Dies

John Todd, one of the pioneers of numerical analysis, died Thursday, June 21, at his home in Pasadena, California. He was 96.

Ooguri Appointed Fred Kavli Professor of Theoretical Physics

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."

Newly Discovered Olympian Galaxy Will Provide Fresh Insights into Galactic Formation

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.

Caltech and Berkeley Astronomers Identify a New Class of Cosmic Explosions

Astronomers are announcing today the discovery of a new class of stellar explosions. The finding is based on observations of a flash seen in the Virgo cluster in a galaxy known as Messier 85.

Astronomers Obtain Highly Detailed Image of the "Red Square" By Using Adaptive Optics of Palomar and Keck Telescopes

Astronomers today announced the arrival of a new member in the pantheon of exotically beautiful celestial objects. Christened the "Red Square" by Peter Tuthill, leader of the team, the image was compiled with data from the 200-inch Hale Telescope at Palomar Observatory, owned and operated by the California Institute of Technology, and the Keck-2 Telescope atop Mauna Kea, Hawaii.

Segment of Quantum Repeater Demonstrated; May Lead to Long-Distance Quantum Communications

Physicists at the California Institute of Technology have succeeded for the first time in the distribution of "entanglement" in a way that could lead to long-distance quantum communications, scalable quantum networks, and even a quantum internet.

Caltech Observatory Receives Science Education Award

The Laser Interferometer Gravitational-Wave Observatory in Hanford, Washington, which was created by the California Institute of Technology and the Massachusetts Institute of Technology, and funded by the National Science Foundation, has received a science education award.
