Fragments of a meteorite that fell to Earth more than a decade ago provide compelling evidence of a lost planet that once roamed our solar system, according to a study published Tuesday. Researchers from Switzerland, France and Germany examined diamonds found inside the Almahata Sitta meteorite and concluded they were most likely formed by a proto-planet at…
We dodged a bullet today. It came within one half of the distance to the moon. I got this notice in email from NASA about a surprise asteroid that gave us only one day of warning passing halfway between the Earth and the moon. It was the largest known asteroid to ever pass that close to Earth…
This is truly spectacular. From NASA and ESA. comes this photo taken by the Hubble Space Telescope which clearly proves [one] of Einstein’s theories – gravitational lensing. Via Wikipedia: The bending of light by a gravitational body was predicted by Albert Einstein in 1912, a few years before the publication of general relativity in 1916 (Renn et al. 1997).…
From Columbia University and the “that’s heavy” department: New Study Suggests Tens of Thousands of Black Holes Exist in Milky Way’s Center A Columbia University-led team of astrophysicists has discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy. The finding is…
Huge hole over 400,000 miles long (700,000 kilometers) is 55 times wider than the Earth A wide hole in the sun’s atmosphere is facing Earth and spewing a stream of solar wind toward our planet. Estimated time of arrival: April 9th. In this extreme ultraviolet image from NASA’s Solar Dynamics Observatory, we see not only the…
From the ROYAL ASTRONOMICAL SOCIETY and the “hot gases in a galaxy far, far, away” department Chemical models developed to help limit the emission of pollutants by car engines are being used to study the atmospheres of hot exoplanets orbiting close to their stars. The results of a collaboration between French astronomers and applied combustion…
From news reports. The world-famous physicist, who died last Wednesday aged 76, was a co-author to a mathematical paper in which he sought to prove the so-called “multiverse” theory, according to a report by U.K. newspaper The Sunday Times. This theory imagines the existence of many separate universes other than our own. The research, submitted two weeks…
