- NRL instrument on NASA satellite sees solar hurricane detach comet tail
10-02-2007 · EurekAlert!
Scientists at the Naval Research Laboratory report they have captured the first images of a collision between a comet and a solar hurricane. It is the first time scientists have witnessed such an event on another cosmic body. One of NASA's pair of Solar Terrestrial Relations Observatory satellites, known as STEREO, recorded the event on April 20, 2007.

- Gamma-ray burst challenges theory
03-08-2007 · EurekAlert!
In a series of landmark observations gathered over a period of four months, NASA's Swift satellite has challenged some of astronomers' fundamental ideas about gamma-ray bursts (GRBs), which are among the most extreme events in our universe. GRBs are the explosive deaths of very massive stars, some of which eject jets that can release in a matter of seconds the same amount of energy that the sun will radiate over its 10-billion-year lifetime.

- Iowa State physicist leads team designing detector for international particle collider
04-13-2007 · EurekAlert!
John Hauptman, an Iowa State University professor of physics and astronomy, is leading an international team that's designing a detector for the proposed International Linear Collider. The collider would be about 19 miles long and accelerate electrons and positrons to nearly the speed of light. The particles would collide at the center of the machine at extremely high energies. Collider detectors would record those collisions. Physicists expect the collisions to create new particles and help them understand how the universe works.

- Birth, death and rebirth: AKARI sees life-cycle of stars in a new light
03-26-2007 · EurekAlert!
Scientists using the AKARI infrared satellite, launched in 2006, are releasing their initial results at a conference on March 28-30. AKARI has shed new light on both the birth and death of stars and galaxies, phenomena that take place in dusty areas of the universe and can best be studied in the infrared.
