‘Frozen reservoir,’ source of a third of California’s water, is far below historical average.
After several months of analysis of Comet 67P/Churyumov-Gerasimenko, the European Space Agency's Rosetta spacecraft has yielded some intriguing, and maybe, unexpected results. The data is refueling a long-running debate in the scientific community about a matter closer to home: the origin of Earth's oceans.
Yesterday morning, the European Space Agency's (ESA) Rosetta spacecraft successfully launched the landing probe, Philae, to a landing on the surface of comet 67P/Churyumov-Gerasimenko, a historic first.
After 10 years of travel and three months orbiting the comet 67p/Churyumov-Gerasimenko, the European Space Agency's (ESA) Rosetta spacecraft is poised to deliver its landing probe, Philae, to the comet's surface -- a first in history.
NASA's latest mission to Mars, MAVEN (Mars Atmospheric and Volatile Evolution), entered Martian orbit less than a month ago on September 21. It's already rewarded us with revealing insights into the disappearance of Mars' atmosphere.
The European Space Agency’s (ESA) Rosetta has reached its target -- the Comet 67p/Churyumov-Gerasimenko -- becoming the first spacecraft in history to rendezvous with a comet.
Europe's Rosetta mission is poised to add another extraterrestrial landfall to a very short list, and top a new list as it becomes the first mission to land a probe on a comet.
Upholding a long-standing tradition of showing us things in space that we have never seen before, the Hubble Space Telescope recently witnessed the break-up of an asteroid.
On Monday, far beyond the orbit of Mars, an alarm clock went off and a robot began the slow process of waking up after a long, cold sleep. The European Space Agency's Rosetta spacecraft is now approaching the comet 67P/Churyumov–Gerasimenko, which it will catch up with this May.
Comet ISON is gone, Comet Lovejoy remains and a sun-grazing asteroid, 3200 Phaeton, is showing comet-like behavior. An interesting December to say the least.
There's been a great deal of anticipation surrounding Comet ISON—and a great deal of debate about whether it will become a Comet of the Century, or fizzle out like so many other comets of the century have in the past. ISON is now visible in binoculars, which may bode well for a good sky show in the coming weeks.
Maybe a week before it passes closest to the sun, the dark side of Comet ISON is expected to begin turning into the sunlight. The sudden exposure to the intense radiation could cause a strong outburst of gases into the coma--like a celestial popcorn kernel suddenly bursting.
A comet named ISON has been hailed as a possible "comet of the century." But scientists aren't sure yet if it will survive a hairpin turn around the sun.
It's time to enjoy the annual Perseid meteors, the Old Faithful of meteor showers that lights up the August night and thoroughly delights those sleepy souls willing to stay up past midnight for one of nature's original fireworks shows.
Envision the Earth plunging through space and passing a sign that warns, “Watch for falling rocks.” Now, what are we going to do deflect a catastrophic collision from space?
