The Taurid meteors, sometimes called the "Halloween fireballs," show up between mid-October and mid-November, but Nov. 5 to 12 will likely be the best time to look for them this year, taking into account both their peak of activity and the effect of increasingly bright moonlight on viewing conditions. After the Moon sets – around 11 p.m. local time on Nov. 5, later on subsequent nights – some 10 to 15 meteors may appear per hour. They are often yellowish-orange and, as meteors go, appear to move rather slowly. Their name comes from the way they seem to radiate from...

Over the next several weeks, our planet will have a close encounter with the Taurid meteor swarm. It will be the closest that we have been to the center of the meteor swarm since 1975, and we won’t have an encounter this close again until 2032. So for astronomers, this is a really big deal. And hopefully there will be no danger to Earth during this pass, but some scientists are absolutely convinced that the Tunguska explosion of 1908 which flattened 80 million trees in Russia was caused by an object from the Taurid meteor swarm. As you will see...

Every year, Earth passes through the tail of the comet Encke - twice. This isn’t unusual. We regularly cross cometary trails of ice and dust. But this one may be different. It could have been the source of the dramatic 1908 Tunguska airburst which flattened hundreds of square kilometres of Russian forest. The 45m wide comet fragment struck on June 30, at the height of the Beta Taurid shower. Was it, in fact, a part of that shower? Astronomer and science advocate Dr Phil Plait says it is possible. Calculations of its trajectory indicate the Tunguska object came from the...

Around 13,000 years ago, the Earth burned. A swarm of comet debris from the Taurid meteor stream had blasted the Americas and parts of Europe; the worst day in prehistory since the end of the ice age. Many species of large animal were exterminated by the conflagration and ensuing cataclysms. And those that survived the initial onslaught could do little against the floods, acid rain, and starvation that followed.

The startling finding means that experts may not be able to spot the massive space rock hidden in the annual Taurids meteor shower until it is too late. According to a group of researchers, one of the fragments could hit Earth in 2022, 2025, 2032 or 2039 during the annual meteor shower. The Taurids is a spectacular meteor shower that lights up the night skies every November. The meteor shower is the trail of debris left by the comet Encke. But the debris could be obscuring two asteroid chunks known as 2015 TX24 and 2005 UR that are potentially Earth-bound....

Comet Encke next perihelion will be in November 21, 2013. It should become visible with binoculars, beginning in late September of 2013 in the evening skies. It will be one of the brightest comets in 2013, but will pale in comparison to Comet ISON (C/2012 S1). After Comet Encke transits the Sun, it will become visible in the morning sky in December... Earth's position in space and the outgassing of Comet Encke are two of the factors that determine when, and if, this comet will become visible to the naked eye at some point in its path around the Sun....

This is a follow up posting to Younger Dryas -The Rest of the Story!Guest post by Don J. Easterbrook Dept. of Geology, Western Washington University.The Younger Dryas was a period of rapid cooling in the late Pleistocene 12,800 to 11,500 calendar years ago. It followed closely on the heels of a dramatically abrupt warming that brought the last Ice Age to a close (17,500 calendar years ago), lasted for about 1,300 years, then ended as abruptly as it started. The cause of these remarkably sudden climate changes has puzzled geologists and climatologists for decades and despite much effort to find...

The theory that the great beasts living in North America 13,000 years ago were killed off by a space impact can now be discounted, a new study claims.Mammoths, giant bears, big cats and the like disappeared rapidly from the fossil record, and a comet or asteroid strike was seen as a possible culprit. But tiny diamonds said to have been created in the collision have been misinterpreted, a US-UK team says. Without these diamonds, the theory falls, the group tells PNAS journal. "This was really the last pillar for this theory and I think it's time now everyone moved on,"...

UK impact crater debate heats up By Jonathan Fildes Science and technology reporter, BBC News Seismic surveys show a trough surrounded by concentric fractures A deep scar under the North Sea thought to be the UK's only impact crater is no such thing, claims a leading geologist. Professor John Underhill, from the University of Edinburgh, says the Silverpit structure, as it is known, has a far more mundane explanation. Detailed surveys reveal nine similar vast chasms in the area, he says. This suggests it was part of a more widespread process, probably the movement of salt rocks at depth, not...

(actual link) Corvid meteors observed only in late June of 1937 may be secondaries from the Giordano Bruno impact in June of 1178. Objects that products meteorite falls, fireballs, airwaves, and flashes on the Moon do not show a preference for late June and, therefore, are not part of the Taurid Complex.

The Dark Ages : Were They Darker Than We Imagined? By Greg Bryant Published in the September 1999 issue of Universe As we approach the end of the Second Millennium, a review of ancient history is not what you would normally expect to read in the pages of Universe. Indeed, except for reflecting on the AD 837 apparition of Halley's Comet (when it should have been as bright as Venus and would have moved through 60 degrees of sky in one day as it passed just 0.03 AU from Earth - three times closer than Hyakutake in 1996), you may...

Explanation: What's happening to that meteor? A few days ago, a bright fireball was photographed from the Alps mountain range in Switzerland as it blazed across the sky. The fireball, likely from the Taurids meteor shower, was notable not only for how bright it was, but for the rare orange light it created that lingered for several minutes. Initially, the orange glow made it seem like the meteor trail was on fire. However, the orange glow, known as a persistent train, originated neither from fire nor sunlight-reflecting smoke. Rather, the persistent train's glow emanated from atoms in the Earth's atmosphere...

Explanation: On November 8, a waning crescent Moon joined the continuing parade of planets in Earth's morning skies. Captured here from Amboseli National Park, Kenya, even the overexposed moonlight can't washout brilliant Venus though, lined up near the ecliptic plane with faint Mars and bright Jupiter above. As if Moon and planets aren't enough, a comparably bright Taurid meteor also streaks through the scene. In fact November's Taurid meteor showers have had a high proportion of bright fireballs. Apparently streaming from radiants in Taurus, the meteors are caused by our fair planet's annual passage through debris from Comet 2P/Encke. The...

ANCHORAGE, Alaska - Alisha Klingenmeyer of Anchorage recalled spotting an orange-red fireball streaking across the sky as she drove north at about 8 p.m. Thursday. Paul Vos was watching a movie with his wife and son at their home in Hope at about 8:30 p.m. the same night when all three saw an arc of light over the mountains in the southern sky.snip This year's Taurids, whose weeklong peak of meteor activity NASA said would start today, were expected to be brighter and more frequent than usual, Chappelow said. "We're running through the (comet's) orbit, which is like a flow,...
