Finding ashes of first stars
Recent observations with the Hubble Space Telescope suggest that the first stars formed as little as 200 million years after the Big Bang. This is much earlier than previously thought. Astronomers have observed large amounts of iron in the ultraluminous light from very distant, ancient quasars. This iron is the "ashes" left from supernova explosions in the very first generation of stars.

Freewheeling galaxies collide in blaze of star birth
A dusty spiral galaxy appears to be rotating on edge, like a pinwheel, as it slides through the larger, bright galaxy NGC 1275 in this NASA Hubble Space Telescope image. Taken with the Wide Field Planetary Camera 2, the image shows traces of spiral structure accompanied by dramatic dust lanes and bright blue regions that mark areas of active star formation.

Scientist sees evidence of 'onions' in space
Scientists may have peeled away another layer of mystery about materials floating in deep space. Tiny multilayered balls called "carbon onions," produced in laboratory studies, appear to have the same light-absorption characteristics as dust particles in the regions between the stars.

Columbia could not be saved, NASA study shows
As NASA and independent investigators close in on the root cause of the Columbia disaster, one question lingers in the minds of many armchair analysts: What, if anything, could have been done to save the crew if engineers had known early on that the orbiter had a non-survivable breach in the leading edge of its left wing?

Hubble gyroscope fails; no impact to science
The Hubble Space Telescope went into "zero gyro safemode," a form of electronic hibernation, early Tuesday when one of the three stabilizing gyroscopes then in operation failed. The telescope is programmed to stop science observations, spin down its remaining gyros and go into safe mode whenever fewer than three gyros are running.

Early Universe sheds light on how elements form
New information from a distant corner of the Universe may lead to a fuller understanding of how the elements of the periodic table -- which make up all the familiar matter in the Universe -- come to be.

Breach moves slightly inboard; key tests on tap
Ongoing analysis of recovered debris from the shuttle Columbia indicates the deadly breach in the ship's left wing may have been centered on a broken leading edge panel and not slightly outboard at a so-called "T-seal" as investigators were thinking last week, the Columbia Accident Investigation Board said Tuesday.

BeppoSAX takes the plunge
A defunct Italian research satellite fell from orbit Tuesday and spread debris across the Pacific Ocean, ending a potential scare to more than 30 nations along the equator that were under the craft's orbital flight path before re-entry.

The search for the missing mass of the Universe
The Universe around us is not what it appears. The stars make up less than 1 percent of its mass; all the gas clouds and other objects, less than 5 percent. This visible matter is mere flotsam on a sea of unknown material -- so called 'Dark Matter' -- a descriptor which mainly serves as an expression of our great ignorance of its nature.
