    Speranza points out another difficulty with the impact-origins theory. Large blocks of limestone sit within the boundaries of the Sirente "crater." Such limestone would not have survived an impact. So if OrmŲ's theory is correct, one must surmise that somebody set these giant chunks of rock in place since the crater formed. To Speranza, that just didn't make sense. Speranza and colleagues further argue that OrmŲ's radiocarbon dating gave one age for the main feature (placing it in the 4th or 5th century a.d.) and a completely different age for a nearby "crater" called C9, a date in the 3rd...

    AN ASTEROID set for a staggering close whistle past of Earth in just 10 days could return to strike the planet as early as next year, NASA has admitted. We are expected to be risk free when the space rock hurtles past us at as close as 11,000 miles away - 21 times closer to us than the moon - on March 8. But the US space agency cannot yet be 100 per cent certain about its orbital path. NASA gives near-Earth asteroid a condition code regarding the certainty of its travel from one to 10, with the latter meaning...

As part Apollo group this 30 meter (100 ft) rock is one of many Near-Earth Objects (NEOs) that periodically crosses Earth's orbit and passes close to our planet. A few years ago, it did just that, flying by our planet at a safe distance of about 2 million km (1.3 million miles).

Asteroid 2003 SD220, also known as asteroid 163899, will pass our planet from 6.7 million miles (11 million km) away - 28 times farther than the moon.

    Here, for the first time (to our knowledge), we are able to demonstrate unambiguously that the impact at the Cretaceous¬ĖPaleogene boundary (K¬ĖPg, ‚ąľ66 Mya) was followed by a so-called ¬ďimpact winter.¬Ē This impact winter was the result of the injection of large amounts of dust and aerosols into the stratosphere and significantly reduced incoming solar radiation for decades. Therefore, this phase will have been a key contributory element in the extinctions of many biological clades, including the dinosaurs.

The spot first caught the eye of an amateur astronomer in Australia, and soon, observatories around the world, including NASAís Hubble Space Telescope, were zeroing in on the unexpected blemish.

Similar scars had been left behind during the course of a week in July 1994, when more than 20 pieces of Comet P/Shoemaker-Levy 9 (SL9) plunged into Jupiterís atmosphere.

    A COLOSSAL asteroid hurtling through space is feared to be one of the biggest EVER to threaten a collision with Earth. The gigantic missile thought to measure almost a mile across will brush closer than previous monsters which have sparked a global panic. Worried astronomers warned 1999 FN53, which is an eighth of the size of Mount Everest, will skim the Earth in TWO DAYS. A collision would be nothing short of catastrophic triggering mass destruction, earthquakes and global extinction. The monster is more than TEN TIMES bigger than other meteorites currently visible on NASAís Near Earth Object radar. It...
  • Close Encounter of the Asteroid Kind Ė 2015 HD1 Skims By Earth Tonight

    Around 3 a.m. (CDT) tomorrow morning April 21, a 50-foot-wide asteroid will hurdle just 0.2 lunar distances or 45,600 miles over your bed. The Mt. Lemmon Survey, based in Tucson, Arizona, snagged the space rock Saturday. 2015 HD1 is about as big as a full grown T-rex through not nearly as scary, since it will safely miss Earth Ö but not by much.

    ďWhile this approximately 400-meter sized asteroid has a three-year orbital period around the sun and returns to the Earthís neighborhood periodically, it does not represent a threat because its orbital path does not pass sufficiently close to the Earthís orbit Ö Any statements about risk for impact of discovered asteroids and comets should be verified by scientists and the media by accessing NASAís Near Earth Object (NEO) program web site.Ē

    Scientists have calculated that 2014 UR116 asteroid will fly in dangerous proximity to Earth every three years. If it collides with the planet the energy of the explosion could be a thousand times greater than the impact of the Chelyabinsk meteorite. Vladimir Lipunov, a leading scientist on the team which discovered the asteroid this October, says the scientists now know its orbit and its period which is 3 years, but they cannot say precisely when the asteroid will approach the Earth. ďWe should track it constantly. Because if we have a single mistake, there will be a catastrophe. The consequences...

    ...the Kola fireball had a 'disturbingly similar' path to asteroid 2014 UR116, which is due to pass by the moon in 2017. Spotted on April 19 last year, researchers used camera footage to help recreate its trajectory and hunt down any remaining fragments... This led researchers to the Annama meteorite, which is an ordinary H5 chondrite -- a group of space rocks with high strength that make up 31 per cent of meteorite falls. The computer model compared the orbit of Annama, a 1,100lb (500kg) rock, with the evolution of a dozen orbits of near-Earth asteroids... Vladimir Lipunov, a professor...

    A 400 kilometre-wide impact zone from a huge meteorite that broke in two moments before it slammed into the Earth has been found in Central Australia. The crater from the impact millions of years ago has long disappeared. But a team of geophysicists has found the twin scars of the impacts Ė the largest impact zone ever found on Earth Ė hidden deep in the earthís crust. Lead researcher Dr Andrew Glikson from the ANU School of Archaeology and Anthropology said the impact zone was discovered during drilling as part of geothermal research, in an area near the borders of...

    Asteroid 2004 BL86, which passed closest to Earth today at a distance of 750,000 miles (1.2 million km), has a companion moon. Scientists working with NASAís 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of the asteroid which show the tiny object in orbit about the main body. ... 2004 BL86 measures about 1,100 feet (325 meters) across while its moon is approximately 230 feet (70 meters) across.

    NASA is saying amateur astronomers with small telescopes and strong binoculars may be able to see the asteroid, although stormy conditions in the Northeast will limit night-time viewing there. Here's how to try to view the asteroid. Editor's note: These times are Eastern Standard Time so adjust them three hours earlier for optimal Pacific Standard Time viewing.]

    CAPE CANAVERAL, Fla. (AP) ó A newly discovered asteroid will pass by Earth this weekend. At closest approach Sunday, the 60-foot rock will pass a safe 25,000 miles over New Zealand. Thatís about one-tenth the distance between here and the moon. Itís also beyond the orbit of our highest communication and weather satellites.

    On Sunday afternoon ó at 2:15 pm Eastern time, to be exact ó a small asteroid will whiz by the Earth. Don't worry: it'll miss us by about 25,000 miles. To be clear, there is zero chance it can hit us. This is certain. But in the long-term, worrying a little about asteroids isn't an unreasonable idea. Now, the odds of a massively destructive asteroid impact at any given time are tiny ó but the potential costs would be enormous. Yet we still haven't invested in all the infrastructure needed to spot small asteroids with much warning (we spotted this...

The asteroid 2014 HQ124, which is the size of a football stadium, poses no chance of hitting Earth in its flyby on Sunday (June 8), and will pass by at a range of three times the distance between the Earth-moon on Sunday (June 8). It was discovered on April 23 by NASA's Wide-Field Infrared Survey Explorer, a sky-mapping space telescope. This afternoon, the online Slooh community observatory will host a live...
