UFO files | Newly released files from The National Archives. Skip to Main Content Home > UFOs UFOs Newly released UFO files from the UK government Files released in June 2013 The final tranche of UFO files released by The National Archives contain a wide range of UFO-related documents, drawings, letters, and photos and parliamentary questions covering the final two years of the Ministry of Defence's UFO Desk (from late 2007 until November 2009).
Discover the reasons behind the closure of the UFO desk, the handling of the largest number of UFO sighting reports received in 30 years and the disclosure campaign for ‘the truth’, which was sparked by the closure of the UFO Desk. Start by reading our highlights guide (PDF, 363kb) to help navigate your way through the files. Previous file releases The National Archives holds other UFO files that have already been released by the Ministry of Defence.

Recent Scenes from Antarctica - Alan Taylor - In Focus. Winter is coming back to Antarctica and, after a busy season for both scientists and tourists, most researchers stationed there have traveled north for the season. Among them were a Russian team that recently came within 30 meters of drilling into Lake Vostok -- a subglacial lake some 4,000 meters below the surface of the ice -- and the crew of the IceCube Neutrino Observatory, who have been burying a massive array of detectors deep in the ice.
(They placed their final detector in December.) Gathered here are recent images of Antarctica, its environment, and some of the scientific work taking place there.

Then whenever anyone posts a new Fireball48 Alert to this page, you will receive an email. You can then come back to this page, scroll down to find this latest Fireball48 alert, follow that link, and then see if you can help.
To post a Fireball48 Yellow Alert, just Reply to this post on this page. Anyone signed up to the Asterisk can do it. A moderator will shortly check your Reply. The moderator may then issue a Red Alert if the lead appears sufficiently interesting. The Fireball48 network is a "virtual citizen science flash mob" who come together briefly to help find videos and images of recently occurring fireballs.
A "Yellow Alert" will mean that we are trying to assess whether a sighting was an actual fireball and whether a flash-mob Fireball48 network could reasonably help find useful images and videos. 2005 March 28 - A Tether in Space.

Tethers, long strands of material, hold the promise of stabilizing satellites, generating electricity, and allowing easy transportation.

Herschel Space Observatory. Galaxy Zoo: Hubble. News Blog - Mike Lynch's "Exploding" Telescope. Here's a cautionary story about someone who was careful with his observing gear — and still got burned. Some of you probably know (or know of) Mike Lynch, an avid amateur astronomer who hosts frequent star parties in the Minneapolis-St.
Paul area. He's the author of several skywatching books, writes a column for the Twin Cities' Pioneer Press, and hosts an astronomy website. You might not know that he's been a meteorologist for radio station WCCO for nearly 30 years. A week ago Lynch headed off to the radio station after observing the night before with his 14½-inch Starmaster Dobsonian. He'd set it up on his back porch and, too tired to drag it back inside, wrapped up the session by slewing the tube down to horizontal, covering it, and placing a towel over the eyepiece hole to prevent dew buildup.
Pretty much standard operating procedure, right? Well, later that morning, Lynch got a frantic call from his wife. It didn't take him long to figure out what had happened. SkyandTelescope.com. Pillow Astronaut. NASA-engineered collision spills new Moon secrets. Scientists led by Brown University are offering the first detailed explanation of the crater formed when a NASA rocket slammed into the Moon last fall and information about the composition of the lunar soil at the poles that never has been sampled.
The findings are published in a set of papers in Science stemming from the successful NASA mission, called LCROSS for Lunar CRater Observing and Sensing Satellite. Peter Schultz and graduate student Brendan Hermalyn analyzed data from bits of the Moon’s surface kicked up by a NASA-engineered collision. They found unexpected complexity — and traces of silver. Credit: Mike Cohea/Brown University Mission control at NASA Ames sent the emptied upper stage of a rocket crashing into the Cabeus crater near the Moon’s south pole last October. A second spacecraft followed to analyze the ejected debris for signs of water and other constituents of the super-chilled lunar landscape. “This was not your ordinary impact,” Hermalyn said.
