ANN ARBOR, Mich. - Why is the universe magnetized? It's a question scientists have been asking for decades.

Discovery could offer clues on the nature of dark matter. In a discovery announced Jan. 18, an international team of researchers has found a dark dwarf galaxy about 10 billion light years from Earth.

by Catherine Zandonella - A rare and exotic mineral, so unusual that it was thought impossible to exist, came to Earth on a meteorite, according to an international team of researchers led by Princeton University scientists.

Two teams of physicists at the U.S. Department of Energy's Fermilab and Lawrence Berkeley National Laboratory (Berkeley Lab) have independently made the largest direct measurements of the invisible scaffolding of the universe, building maps of dark matter using new methods that, in turn, will remove key hurdles for understanding dark energy with ground-based telescopes.

Researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft.

ANN ARBOR, Mich. - Astronomers have detected a mysterious ring of carbon monoxide gas around the young star V1052 Cen, which is about 700 light years away in the southern constellation Centaurus.

Cornell scientists are boldly going where no water molecule has gone before - that is, when it comes to pressures found nowhere on Earth.

A team of astronomers led by scientists at the California Institute of Technology (Caltech) has discovered the three smallest confirmed planets ever detected outside our solar system.

When fans tune in to watch the Super Bowl, they are also watching "a whole lot of physics" as well, notes Yale scientist Anissa Ramirez.
