A University of Bologna team says a lake near the epicentre of the biggest space impact in modern times - the Tunguska event, may be occupying a crater hollowed out by a chunk of rock that hit the ground. picked by DrNothing 2 years ago

Geophysicists now have created the most detailed 3-D seismic images yet of the mostly submerged Chicxulub impact crater. The images show the crater contained sulfur-rich sediments that would have reacted with the water vapor to create sulfate aerosols. These compounds in the atmosphere would have made the impact deadlier by cooling the climate and producing acid rain. picked by AutumnLotus 12 months ago

Astronomers from SRON Netherlands Institute for Space Research have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away. The astronomers made the discovery as part of an international team using the space telescope XMM-Newton. picked by AutumnLotus 1 year ago

A mysterious metallic object that crashed through the roof of a New Jersey home earlier this year was not a meteorite after all, but probably a piece of space junk, scientists said Friday. picked by AutumnLotus 2 years ago

Last September, a supernova burst into a cosmic flame 100 times more intense than any event on record—and left scientists scratching their heads. Now, two new studies attempt to explain the remarkable explosion. One sets up the explosion with a cannibalistic star, while the other describes how colliding layers of jettisoned gas could outshine all other supernovae. picked by AutumnLotus 1 year ago

Using the powerful one-two combo of NASA’s Swift satellite and the Gemini Observatory, astronomers have detected a mysterious type of cosmic explosion farther back in time than ever before. The explosion, known as a short gamma-ray burst (GRB), took place 7.4 billion years ago, more than halfway back to the Big Bang. picked by AutumnLotus 12 months ago

A cosmic explosion that seems to have come out of nowhere—thousands of light-years from the nearest collection of stars—has left astronomers baffled. The blast, one of the brightest this year, was detected by spacecraft from the Inter-Planetary Network on Jan. 25 and satellites were used to pinpoint its location to a region of the sky in the constellation Gemini. picked by AutumnLotus 1 year ago

Astronomers from SRON Netherlands Institute for Space Research have discovered mysterious pulses that are being emitted by an extremely magnetic star. The magnetic star, a magnetar, emits the pulses as very high energy X-rays. picked by AutumnLotus 8 months ago

Yesterday this was being reported as a gas pipeline explosion (http://www.russiatoday.ru/news/news/11413). Today it has become an explosion at a nuclear power station (assuming it is the same explosion - not sure). Here are some photos and vids.

If these are the same explosion, the way it is unfolding is reminding me a lot of how the Chernobyl/Pripyat explosion was reported picked by pocksucket 1 year ago

Next time you’re virtually roaming Google Earth, make sure you take a close look at any unusual landforms.

Geologist Arthur Hickman did just that, and is now the proud parent of the Hickman Crater, a meteorite crater in the Hamersley Ranges. picked by AutumnLotus 10 months ago

For the past 30 years or so an astounding renovation has been underway below roden crater, a 3km wide dormant volcano crater located northeast of Flagstaff in Arizona, the brilliance of which probably won't be apparent until the large-scale art installation opens when ready, apparently in 2012. picked by AutumnLotus 3 months ago

Scientists said Friday they had found remains of a meteor that illuminated the sky before falling to earth in western Canada earlier this month. picked by Bornbad 1 month ago

A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into ‘killers’. ESA’s Cluster constellation has contributed crucially to the finding. picked by AutumnLotus 1 year ago

A new class of cosmic object has been found by a Dutch schoolteacher, through a project which allows the public to take part in astronomy research online. Hanny Van Arkel, 25, came across the strange gaseous blob while using the Galaxy Zoo website to help classify galaxies in telescope images. picked by AutumnLotus 5 months ago

Located at Turkmenistan desert, Darvaza flaming crater is 60 meters in diameter and 20 meters depth and is not caused by volcanic activity or a meteorite impact. This crater was created sometime in the 50's when the Soviets were prospecting for natural gas in this area and it's been burning since then. picked by wildminou 10 months ago

A lake that might once have been habitable may have filled a crater for a long time on early Mars, new spacecraft images reveal. NASA's Mars Reconnaissance Orbiter captured the images that suggest the debris-strewn Holden Crater once held a calm body of water that could have harbored life. picked by AutumnLotus 10 months ago

Antimatter, which annihilates matter upon contact, seems to be rare in the universe. Still, for decades, scientists had clues that a vast cloud of antimatter lurked in space, but they did not know where it came from. The mysterious source of this antimatter has now been discovered -- stars getting ripped apart by neutron stars and black holes. picked by AutumnLotus 12 months ago

A Russian drilling rig has penetrated through more than two miles of Antarctic ice and is within about 70 meters of a huge subglacial lake that may harbor microbial colonies that are unlike anything ever seen on Earth. It's an exciting time for some scientists, and a matter of concern to others. picked by AutumnLotus 1 year ago
