Two Suns? Twin Stars Could Be Visible From Earth By 2012 By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. When that happens, for at least a few weeks, we’d see a second sun, Carter says. The Star Wars-esque scenario could happen by 2012, Carter says... or it could take longer. But doomsday sayers should be careful about speculation on this one. In fact, a neutrino shower could be beneficial to Earth. UPDATE: To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth, but implies a supernova could be beneficial, stating, "Far from being a sign of the apocalypse, according to Dr Carter the supernova will provide Earth with elements necessary for survival and continuity."

The Town that spent 25 Years Underwater | Messy Nessy ChicMessy Nessy Chic This is Villa Epecuen, an old tourist town south of Buenos Aires that spent a quarter of a century underwater. Established in the 1920s on the banks of a salt lake, the town was home to over 5,000 residents and a holiday destination to thousands more vacationers from the Argentinian capital. In 1985, a dam burst and buried the town in 33 feet of salt water, rendering it a modern-day Atlantis. Initially, people waited on their roofs, hoping for the water to recede. It didn’t, and within two days, the place was a devastated ghost town. In 2009, the waters began to recede and what emerged resembles an apocalyptic world. Evenly-spaced dead trees still line what used to be streets, rusty bed frames poke out from concrete rubble and sign posts point to nowhere. Amazingly, one resident remained in this desolate place.

Copyright 2010 Ben Gilliland Theme by Dr. Archaeologists unearth 5,000-year-old 'third-gender' caveman Archaeologists investigating a 5,000-year-old Copper Age grave in the Czech Republic believe they may have unearthed the first known remains of a gay or transvestite caveman, reports the Telegraph. The man was apparently buried as if he were a woman, an aberrant practice for an ancient culture known for its strict burial procedures. Since the grave dates to between 2900 and 2500 BC, the man would have been a member of the Corded Ware culture, a late Stone Age and Copper Age people named after the unique kind of pottery they produced. "From history and ethnology, we know that people from this period took funeral rites very seriously so it is highly unlikely that this positioning was a mistake," said lead archaeologist Kamila Remisova Vesinova. Another clue is that Corded Ware men would typically be buried alongside weapons, hammers and flint knives, as well as food and drink to prepare them for their journey to the other side.
Earth-size planet found: Lightest exoplanet yet orbits Sun-like star Alpha Centauri B Newly found world orbits Alpha Centauri B, 4.3 light years from our SunIt is the lightest exoplanet yet found orbiting a Sun-like starIt is thought to be too hot for life, and there is likely no water presentBut presence suggests there may be other planets within the same system By Daily Mail Reporter Published: 08:18 GMT, 17 October 2012 | Updated: 12:37 GMT, 17 October 2012 An Earth-sized planet has been found orbiting a star in Alpha Centauri, our nearest neighbouring solar system. The mystery world circling Alpha Centauri B is thought to be much too hot to support life, with surface temperatures of around 1,500C. But astronomers say it is likely to be part of a more extensive solar system containing other planets, one or more of which might be habitable.

New comet likely to impress when it passes closest to Earth in December By Alan Pickup, The GuardianSunday, October 14, 2012 20:16 EDT A comet found recently beyond the orbit of Jupiter could well become spectacular late next year and may be a sibling of one of the most celebrated comets of all time. What is formally known as Comet C/2012 S1 (ISON) was not at first recognised as a comet when it was spotted as a 19th magnitude object using a small Russian telescope of the International Scientific Optical Network on 21 September. Its orbit resembles that of Kirch’s Comet, the Great Comet of 1680, which hangs over Rotterdam in our illustration from a painting by the Dutch artist Lieve Verschuier. This is not to say that the comet of 1680 and Comet ISON are the same object since both probably take thousands of years to orbit the Sun. The fact that Comet ISON is seen easily so far from the Sun suggests that it is large enough to survive its solar encounter and that it will not fizzle out as some close-approach comets have done before.

Physics 20b: Introduction to Cosmology - Spring 2010 - Download free content from UC Irvine Top 10 Strangest Things In Space Space Let’s be honest: space is an absolutely crazy place. Most science fiction writers throw in a planet with two stars that looks vaguely like Southern California, and call it a day. Everyone knows that shooting stars are just meteors entering the atmosphere, right? When a binary star system is gobbled down by the supermassive black hole (that’s the scientific term, by the way) at the center of a galaxy, one of the two partners is consumed, while the other is ejected at high speed. Gliese 581 c wants to kill you. This planet orbits a red dwarf star, many times smaller than our Sun, with a luminosity of only 1.3% of our sun. The tidal locking of the planet alone results in some pretty odd features. Living on Gliese 581 c would have its challenges, though. As if one or two giant, fiery balls of gas weren’t enough, here we have the Castor System. Space Raspberries and Rum For the last few years, scientists have been studying a dust cloud near the center of our Milky Way galaxy.
Scientists say mysterious 'Oumuamua' object could be an alien spacecraft Get the Mach newsletter. Nov. 5, 2018 / 7:06 PM GMT By David Freeman Maybe it's an alien spacecraft. Scientists have been puzzling over Oumuamua ever since the mysterious space object was observed tumbling past the sun in late 2017. Now a pair of Harvard researchers are raising the possibility that Oumuamua is an alien spacecraft. The researchers aren't claiming outright that aliens sent Oumuamua. Who would have sent such a spacecraft our way — and why? "It is impossible to guess the purpose behind Oumuamua without more data," Avi Loeb, chairman of Harvard's astronomy department and a co-author of the paper, told NBC News MACH in an email. Earthlings have launched simple solar-powered lightsails of our own, and Loeb is an adviser to Breakthrough Starshot, an initiative that plans to send a fleet of tiny laser-powered lightsail craft to the nearest star system. Coryn Bailer-Jones, an astronomer at the Max Planck Institute for Astronomy in Heidelberg, Germany, voiced similar objections.
Scientists detect rare crash of two mismatched black holes for the first time ever | Space Colliding black holes aren't always as evenly matched as scientists expected, according to a cosmic chirp astronomers have puzzled over for a year. On April 12, 2019, gravitational wave detectors picked up a signal of space-time ripples caused by colliding black holes — which in and of itself has gone from groundbreaking to nearly mundane over the past five years. But as scientists studied the detection more closely, they realized that it didn't match the signals they have seen so far. Instead of two evenly matched black holes, the new detection seemed to be triggered by a lopsided merger in which one black hole was three or four times more massive than the other. "It's an unlikely observation," Maya Fishbach, a doctoral candidate at the University of Chicago who presented the new discovery, said during her talk. Related: Eureka! Scientists studied those 10 mergers during LIGO's first two observing runs, conducted between 2015 and 2017. Related: Eureka!
