When a meteor weighing some 11,000 metric tons exploded over Russia earlier this year, much of the remaining debris fell to the ground -- but not all. Ultimately, some 100 tons of dust from the meteor, or bolide, became locked in the atmosphere, offering NASA officials an unprecedented opportunity to observe as this material went on to create a thin but cohesive dust belt in the stratosphere.
Two Russian cosmonauts ventured outside the International Space Station (ISS) today in the latest spacewalk designed to prepare for the arrival of a Russian laboratory module later this year.
In an exciting first, a new series of images taken by NASA's Mars rover Curiosity tracks the slow, steady passage of Mars's larger moon, Phobos, passing in front of its pint-sized little brother Deimos.
It's official: NASA's Kepler telescope is no longer capable of carrying out its original planet-hunting mission.
A new study suggests the Voyager 1 spacecraft, which has been flying on an outward-bound trajectory through the solar system since 1977, left the realm of the Sun's influence a year ago and has been passing through interstellar space.
In a galaxy far, far away - about 60 million light years from Earth - a huge cloud of unfathomably hot gas spotted by NASA's Chandra X-Ray Observatory tipped astronomers towards an amazing cosmic spectacle -- the collision of a dwarf galaxy and one of its much larger brethren.
SpaceX's Grasshopper hit another milestone this week when it completed a "divert" test, the company announced Wednesday.
When it comes to putting man on Mars, there's a lot to consider -- including what astronauts will eat for dinner. To get a sense of what may be the best ingredients to pack for such an extended mission, six scientists have spent the last four months in a simulated mission to Mars, emerging from the experiment on Tuesday with pages of notes.
The elusive phenomenon known as sprites was recently caught on camera by scientist Jason Ahrns while aboard the National Center for Atmospheric Research's Gulfstream V research aircraft.
Besides offering insight into the formation, evolution and composition of the solar system, asteroids could one day prove a veritable source of much needed resources as humankind continues to grow in leaps and bounds. However, before this can happen, scientists have yet to determine a way to retrieve or otherwise access them. For this reason, researchers from the University of Strathclyde in the UK have run an analysis of all currently known Near-Earth Objects (NEOs) in order to determine a new category: Easily Retrievable Objects (ESOs).
In addition to the state-of-the-art equipment necessary for carrying out its mission, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission will carry with it over 1,100 haikus on its journey to Mars.
August is here and with it barbecues, trips to the pool and, of course, the Perseid meteor shower.
Scientists at the Lawrence Berkeley National Laboratory have used a new analysis of cosmic microwave background (CMB) radiation to take a look back in time to the beginnings of our universe. The scientists report observable data that originated anywhere from 100 to 300,000 years after the Big Bang, a breakthrough they are calling the furthest look back through time ever accomplished.
Evidence that Jupiter's ice-covered moon Europa may be able to support life has prompted a team of NASA scientists to consider science goals for a landed spacecraft mission to its surface.
The latest image to come out of the European Southern Observatory’s (ESO) Very Large Telescope (VLT) represents an intriguing star-forming region in one of the Milky Way’s satellite galaxies known as the Large Magellanic Cloud (LMC).
