Based on new data, NASA's Jet Propulsion Laboratory has lowered the odds that the comet Sliding Spring will hit Mars when it approaches the Red Planet in later in 2014, according to a NASA statement.
Commercial space travel is close - really close. Or, at least, that's how it felt for onlookers who watched another successful test flight by Virgin Galactic's SpaceShipTwo rocket plane on Friday.
Sending humans to Mars has long been a fascination for generations of space enthusiasts, but sheer distance is only one of myriad factors keeping the dream from becoming reality. But one Mars-bound organization has a novel, if not sobering, approach to getting man to the Red Planet: make it a one-way ride.
A blazing fireball - apparently a fragment from a comet - stunned skywatchers during weekend as it burned up in the night sky over Spain at 75,000 kilometers per hour (46,603 mph) before burning out over the Serranillos Valley.
NASA awarded the University of Central Florida a $55 million grant to build and launch an instrument that will provide "unprecedented imaging" of the Earth's upper atmosphere, according to the university.
The International Astronomical Union (IAU) has now warmed public about sham sites that are offering people the rights to nominate a planet.
Sunday, April 14, stargazers can use the Moon as a marker to spot Jupiter, even in the daylight sky.

The seasons are changing and not just on Earth - scientists at NASA are reporting signs that Titan, Saturn's largest moon, is currently in flux and it may have a lot to say about our own planet's changing climate.
A mildly powerful solar flare which erupted from the Sun early Thursday is associated with an coronal mass ejection (CME) that is speeding towards the planet at some 600 miles per second, likely to cause a geomagnetic storm when it arrives.
Using the W.M. Keck Observatory on Mauna Kea in Hawaii, astronomers witnessed the gas giant's rings "rain" charged water particles down onto Saturn's ionosphere in much larger volumes and across more area that ever seen before, revealing the rain influences the temperature structure of parts of Saturn's upper atmosphere.
Just three years after discovering people aboard commercial airplanes could be subjected to gamma-ray radiation, physicist Joseph Dwyer says the doses may not be very worrisome.
