Here, for the first time (to our knowledge), we are able to demonstrate unambiguously that the impact at the Cretaceous–Paleogene boundary (K–Pg, ∼66 Mya) was followed by a so-called “impact winter.” 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 K–Pg boundary impact presents a unique event in Earth history because it caused global change at an unparalleled rate. This detailed...

I am going to skip down this article, and post what I think might have something to do with the Jan 29th, 2010 Comet-Asteroid P/2010 A2 taken by NASA as a Heavenly Sign of Jesus Christ, in addition Dec 21, 2010 there is a total (Red) Moon Lunar Eclipse* "Constantine was warned in a dream to make the celestial sign of God upon his soldiers' shields, and so to join battle. He did as he was bid, and with the transverse letter X circumflecting the hand of it, he marks Christ on their shields. Equipped with this sign, his army...

Astronomy Ireland says a major fireball was spotted over Ireland at around 6pm this evening. It says the rock from space was seen blazing in the air by people all over the country and would have been travelling with the force of a small nuclear weapon. Astronomy Ireland says there is a very good chance it has landed inland, but it is unlikely to have injured anyone. It is not clear yet where it might have landed because the fireball was spotted by people all over the country. While it would have been travelling at high speed when it was...

P/2010 A2: Unusual Asteroid Tail Implies Powerful Collision Credit: NASA, ESA, D. Jewitt (UCLA) Explanation: What is this strange object? First discovered on ground based LINEAR images on January 6, the object appeared unusual enough to investigate further with the Hubble Space Telescope last week. Pictured above, what Hubble saw indicates that P/2010 A2 is unlike any object ever seen before. At first glance, the object appears to have the tail of a comet. Close inspection, however, shows a 140-meter nucleus offset from the tail center, very unusual structure near the nucleus, and no discernable gas in the tail....

Collisions between asteroids should be highly energetic affairs, with an average impact speed of close to 5 kilometers per second. We may be looking at the debris of a head-on collision between two asteroids in imagery provided by the Hubble Space Telescope. The object in question, originally thought to have been a comet, is P/2010 A2, discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) sky survey on January 6 of this year. The follow-up Hubble imagery dates from late January, and shows an unusual filamentary pattern near the nucleus.Image: HST picture of the comet-like object called P/2010 A2. The object...

Another processing of the experimental photographer Vincenzo Giovanni Ruello revealing the actual asteroid in close up P/2010-A2 originally photographed by Hubble telescope in 2010

A strange comet-like object discovered in 2010 ended up being an asteroid that had been the victim of a head-on collision from another space rock. The object created a bit of buzz because of its mysterious X-shaped debris pattern and long, trailing streamers of dust. Named P/2010 A2 (LINEAR), the object is located in the asteroid belt between Mars and Jupiter, and has been the focus of much study, including images taken by the Hubble Space Telescope and many ground-based observatories. But over time, the asteroid’s long dust tail has grown to be so long that the entire object can’t...
