Rare galaxy at ‘dawn of time’

Astronomers using NASA’s Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found to date at such great distances.

Researchers detail how a distant black hole devoured a star

NASA’s Swift satellite first alerted astronomers to intense and unusual high-energy flares from the new source in the constellation Draco… Astronomers soon realized the source, known as Swift J1644+57, was the result of a truly extraordinary event — the awakening of a distant galaxy’s dormant black hole as it shredded and consumed a star. The …

Voyager 1 reaches edge of the solar system: the heliosphere stagnation region

“Voyager tells us now that we’re in a stagnation region in the outermost layer of the bubble around our solar system,” said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. “Voyager is showing that what is outside is pushing back. We shouldn’t have long to wait to find out what …

Fermi telescope finds huge gamma ray bubbles from Milky Way center

NASA’s Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy… The structure spans more than half of the visible sky, from the constellation Virgo to …

The galaxy (probably) abounds in Earth-like planets

What percentage of Sun-like stars have earth-like planets orbiting them? As many as one-fourth, according to a new survey performed by astronomers at the University of California. This result contradicts previous theories of planet formation, but is a tantalizing prediction that finding extraterrestrial life, or at least Earth’s twin, is not impossible. via The galaxy …

New cosmological model: no bang, no time, and no constants

There are four distinguishing features of these models: 1) the speed of light and the gravitational “constant” are not constant, but vary with the evolution of the universe, 2) time has no beginning and no end, 3) the spatial section of the universe is a 3-sphere, and 4) the universe experiences phases of both acceleration …
