A boulder-sized meteor that struck the moon in March may have indeed caused the biggest lunar explosion ever observed by NASA.
A Russian capsule filled with 45 mice and 15 newts has returned to Earth from a month-long mission in orbit with data scientists hope will pave the way for a manned flight to Mars.
NASA scientists have recorded the biggest explosion yet on the moon from a meteorite impact. The findings come after eight years of monitoring the lunar surface for just these types of collisions.
A binary neutron star system known as Circinus X-1 spews energetic matter from its core into the surrounding system in the form of compact jets. Now, astronomers have observed this system in unprecedented detail for the first time.
NASA's Kepler telescope has been hunting for alien planets since 2009. Now, the instrument's mission may be over. NASA has announced that the telescope is broken, which potentially jeopardizes the search for other worlds where life could exist.
A rover has been making its way across the surface of Mars for nine years, steadily recording data during its lone trek. Now, Mars Exploration Rover (MER) Opportunity has broken a record. It's travelled the farthest of any extraterrestrial vehicle.
A major upgrade of the GPS satellite navigation system is underway, with aging GPS satellites being replaced with the latest generation, having more powerful capabilities. The U.S. Air Force launched the fourth of the new version GPS IIF satellite this week, which offers improved navigational accura...
The first scientific results using the new Karoo Array Telescope (KAT-7) in South Africa, the pathfinder radio telescope for the $3 billion global Square Kilometre Array (SKA) project, have been published by an international team of astronomers this week.
There are some scary things out there in space, and an asteroid the size of nine cruise ships is one of them. NASA officials have announced that the massive asteroid 1998 QE2 will sail past Earth on May 31.
Mars is making less of an impact--at least as far as its craters are concerned. Scientists have discovered that space rocks are smashing into the Red Planet far less frequently than once thought.
Uranus and Neptune are home to some of the most extreme winds that can be found in our solar system. Now, researchers have set an upper limit for the thickness of jet streams on the planets; they've learned a little bit more about the surface weather on these two worlds.
Far from Earth, a massive black hole resides in the center of a galaxy known as 4C+29.30. There, it spews two speeding jets of particles into space. Now, astronomers have captured this black hole and its jets in a spectacular image.
