Unique cosmic coincidence - comets Encke and ISON to fly by Mercury

Comet Encke will fly by Mercury within 0.025 AU (3.74 million km) on November 18, 2013 and only a day later, Comet ISON will pass it at 0.24 AU. This is a unique cosmic coincidence and NASA's MESSENGER spacecraft, which is orbiting the planet,

Astronomers discovered asteroid spouting six comet-like tails

Astronomers have observed a unique and baffling object in asteroid belt with six comet like tails of dust radiating from it. While this object is on an asteroid-like orbit, it looks like a comet, and is sending out tails of dust into space. Unlike all other

Annual Orionid meteor shower peaks tonight

It's time for annual Orionid meteor shower. The Orionid meteor shower is associated with Comet Halley's debris which strike Earth's atmosphere usually in late October. With Eta Aquarids in early May, Orionids are one of two annual meteor

Cometary collisions as source of life on Earth

Comets contain elements such as water, ammonia, methanol and carbon dioxide that could have supplied the raw materials, in which upon impact on early Earth would have yielded an abundant supply of energy to produce amino acids and jump start life. In a research that

Meteorite minerals hint at Earth extinctions, climate change

A huge asteroid that wiped out the dinosaurs may not have been the only cosmic event to cause mass extinctions or change Earth’s climate. Tiny minerals leftover from many smaller meteorites could provide the geological evidence needed to show how rocks falling

Biggest extinction in history caused by climate-changing meteor

It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact

Armagh cameras catch unexpected outburst of meteors

A surprise flurry of meteors or "shooting stars" caught the eye of several casual observers in Western Europe on the night of 9–10 September. The meteors were apparently quite fast, with some bright enough to qualify as fireballs. They were recorded by
