Large diamonds made from gas are the hardest yet
Source: CarnegieInstitution Posted: 2/25/04
Producing a material that is harder than natural diamond has been a goal of materials science for decades. Now a group* headed by scientists at the Carnegie Institution’s Geophysical Laboratory in Washington, D.C., has produced gem-sized diamonds that are harder than any other crystals.

Scientists at the Canadian Institute for Theoretical Astrophysics (CITA) and NASA have captured unprecedented details of the swirling flow of gas hovering just a few miles from the surface of a neutron star, itself a sphere only about ten miles (16 km) across.

Hubble and Keck find farthest known galaxy in the Universe
Source: ESA Posted: 2/16/04
An international team of astronomers may have set a new record in discovering what is the most distant known galaxy in the Universe. Located an estimated 13 billion light-years away, the object is being viewed at a time only 750 million years after the big bang, when the Universe was barely 5 percent of its current age.

Oxygen and carbon discovered in exoplanet atmosphere ‘blow-off’
Source: NASA/ESA Posted: 2/3/04
Oxygen and carbon have been found in an extrasolal planet's atmosphere, evaporating at such an immense rate that the existence of a new class of extrasolar planets – ‘the chthonian planets’ or ‘dead’ cores of completely evaporated gas giants - has been proposed.
