Two Suns? Twin Stars Could Be Visible From Earth By 2012

Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. 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 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.

Astronomers discover two planets orbiting a two-star system : University of Hawaiʻi System News

Credit: NASA/JPL-Caltech/T. Pyle A team of astronomers, including University of Hawaiʻi at Mānoa Associate Astronomer Nader Haghighipour, has discovered the first two-planet system orbiting two stars. Their study was published in the journal Science. Known as Kepler-47 because the data came from the Kepler spacecraft, this planetary system demonstrates that complete planetary systems can exist around a pair of stars.

The system contains the smallest known planet orbiting a pair of binary stars. More important, the outer planet’s orbit and the spectral types of the stars (G and M) place the planet well within the “habitable zone,” the region where a terrestrial planet could have liquid water on its surface.

As regional metropolitan areas expand in both physical area and population, they typically aggregate to form economically, politically, and to some extent socially linked entities known as conurbations — the term “megalopolis” has also been used.

Scientists discover one of the biggest structures in the Universe

It’s a galaxy that gives births to more stars in a day than ours does in a year. Astronomers used NASA’s Chandra X-Ray telescope to spot this distant gigantic galaxy creating about 740 new stars a year. By comparison, our Milky Way galaxy spawns just about one new star each year. The galaxy is about 5.7 billion light years away in the center of a recently discovered cluster of galaxies that give off the brightest X-ray glow astronomers have seen.

But this is the size, type and age of galaxy that shouldn’t be producing stars at such a rapid pace, said the authors of a study published Wednesday in the journal Nature. "It’s very extreme," said Harvard University astronomer Ryan Foley, co-author of the study. 50_Years_Space_Exploration1.jpg (3861×1706) Photopic Sky Survey.
