An enormous belt of carbon monoxide gas lies in the disk of debris surrounding Beta Pictoris, a young star 63 light-years from Earth. The source of the gas is probably comets, which may have been trapped there by a big alien planet.
Comet ISON — that bright comet last year that broke up around Thanksgiving weekend — included two forms of nitrogen in its icy body, according to newly released observations from the Subaru Telescope. Of the two types found, the discovery of isotope 15NH2 was the first time it’s ever been seen in a comet. Further, […]
Edmond Halley is best remembered for predicting the orbit of the comet that was later named after him. Besides astronomy, he also made significant discoveries in the fields of geophysics, mathematics, meteorology and physics.

Comet Siding Spring will approach within 86,000 miles of Mars on Oct. 19, potentially putting on a great show for NASA's Red Planet spacecraft. But the dust shed by the comet may also endanger the agency's Mars orbiters.
One of the big ticket astronomical events of 2014 will be the close passage of Comet C/2013 A1 Siding Spring past the planet Mars in October 2014. Discovered just over a year ago from the Australian-based Siding Spring Observatory, this comet generated a surge of excitement in the astronomical community when it was discovered that it was […]
Now that Rosetta has (leisurely) arose from a 31-month slumber in space, the next step is to figure out how prepared the spacecraft is for its close encounter with a comet. Early indications show that the orbiting spacecraft is ready to go. Its lander, Philae, is still asleep and the plan isn’t to wake it […]
The silence from the live video feed from the ESA’s space operations center in Darmstadt, Germany was almost deafening. Scientists and engineers were waiting to receive a signal from the Rosetta spacecraft, which was supposed to come out of hibernation today to begin its mission to Comet 67P/Churyumov-Gerasimenko in earnest. Finally, after waiting nearly 45 […]
Watch live streaming video from eurospaceagency at livestream.com UPDATE: Rosetta woke up! Read our full story about the acquisition of signal here. For the first time, a spacecraft will follow a comet as it approaches the Sun and land on its nucleus. But today is key to the success of the mission. After nearly two […]
