Peering beneath the ice at the north pole of Mars has now revealed the red planet may be surprisingly colder than was thought.

The universe is twice as bright as it appears, astronomers now suggest.

I visited Richard Quinn's lab at NASA Ames Research Center to learn more about his work on Earth and on Mars. Richard Quinn and John Marshall are both scientists in the Carl Sagan Center at the SETI Institute; they are instrument scientists and team members on NASA's soon-to-land Mars Phoenix Lander.

Asteroid and comet impacts on Earth can cause catastrophic extinction events. They can also bring life back, new research shows.

Physicists have come up with a way to explain how information could escape from a black hole, an idea that's been debated since the 1970s.

An unmanned Russian cargo ship launched into orbit Wednesday crammed with fresh supplies for astronauts aboard the International Space Station (ISS).

About 140 years ago, our time, a stellar explosion lit up our galaxy with a blinding flash of light, sending out powerful shock waves to boot. Now, astronomers have spotted the youthful remains from the explosion.

NASA's Phoenix Mars Lander aims to not flame out when it descends to the arctic surface of the red planet in less than two weeks.

Exploring the universe can be as simple as turning on your home computer thanks to a new digital archive filled with views from some of the world's best land- and space-based telescopes.

When space shuttle Discovery touched down in December 2006 after spending 13 days in space traveling 5.3 million miles, it came to rest on four main landing gear and two nose gear tires. Although not much larger than a truck tire, just one of Discovery's main gear tires could carry three times the load of a Boeing 747 tire or the entire starting line-up of a NASCAR race — 40 race cars — all hitting the pavement at 250 miles per hour.

WASHINGTON — With just 12 days to go until its Mars arrival, NASA's Phoenix lander is functioning well and on course to be the first mission to land in the frigid, arctic regions of the red planet, NASA officials said today.

The sun bounces up and down as it roams the Milky Way, and such wavering might have hurled showers of comets Earth's way that caused mass extinctions, including the one that killed the dinosaurs, a new study claims.

Astronomers have found a piece of the universe's puzzle that's been missing for awhile: a type of extremely hot, dense matter that is all but invisible to us.

The crew of the space shuttle Discovery successfully completed a dress rehearsal today for their upcoming launch. They capped off their practice run at Cape Canaveral with a simulated countdown to liftoff at 11:00 a.m. EDT.

A prototype module for a private space station has passed an orbital milestone after completing its 10,000th trip around the Earth.

ALBUQUERQUE, N.M. — International planning is under way to reinvigorate plans for a Mars sample return mission, with researchers assessing science priorities and strategies to maximize the scientific output from such an undertaking.

As soon as darkness falls these evenings, step outside and look skyward. What is the most prominent and easiest star pattern to recognize? If you live in the Northern Hemisphere you only need to look overhead and toward the north where you will find the seven bright stars that comprise the famous Big Dipper.

NASA's shuttle Discovery is on track to ferry seven astronauts and a large Japanese laboratory to the International Space Station (ISS) later this month.

A student at the University of Mississippi will leap into the final frontier of the legal system Saturday when he receives the first-ever space law certificate in the United States.
