    NASA’s Fermi Telescope Finds Giant Structure in our Galaxy

    NASA Nov 10, 2010 WASHINGTON — 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. “What we see are two...

    Huge Bubbles Found at Milky Way's Heart Could Signal a Black Hole Eruption

    Scientists have detected two gigantic bubbles of high-energy radiation spilling out from the Milky Way's center that may have erupted from a supermassive black hole. The mysterious structures each span 25,000 light-years across, and are emitting gamma rays, the highest-energy wavelength of...

    Massive gamma ray bubbles discovered in galaxy center

    WASHINGTON (AFP) – Two huge, unexplained gamma ray emitting bubbles have been discovered at the center of the Milky Way galaxy, US astronomers said Tuesday. Masked by a fog of gamma rays that appears throughout the sky, the bubbles form a feature spanning 50,000 light-years and could be the...

    Astronomers discover most massive galaxy yet of 800 trillion suns

    Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster ever. It lies at a distance of around 7 billion light-years away. In fact there are several galaxies located in one find. The cluster designated SPT-CL J0546-5345 weighs in at over 800...

    Lava likely made river-like channel on Mars

    Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. Whether channels on Mars were formed by water or by lava has been debated for years, and the outcome is...

    Old star is "missing link" in galactic evolution

    A newly discovered star outside the Milky Way has yielded important clues about our galaxy's evolution. Located in the dwarf galaxy Sculptor some 280,000 light-years away, the star has a chemical make-up similar to the Milky Way's oldest stars, supporting theories that our galaxy grew by...

    Newborn black holes may add power to many exploding stars

    Astronomers studying two exploding stars, or supernovae, have found evidence that the blasts received an extra boost from newborn black holes. The supernovae were found to emit jets of particles traveling at more than half the speed of light. Previously, the only catastrophic events known to...

    Climategate: the corruption of Wikipedia

    James Delingpole London Telegraph Tuesday, Dec 22nd, 2009 If you want to know the truth about Climategate, definitely don’t use Wikipedia. “Climatic Research Unit e-mail controversy”, is its preferred, mealy-mouthed euphemism to describe the greatest scientific scandal of the modern age. Not...

    Scientists discover Earth-like, water-rich planet: study

    PARIS (AFP) – Astronomers have discovered a new Earth-like planet that is larger than our own and may be more than half covered with water, according to a study published Wednesday in the science journal Nature. The so-called "super Earth" is about 42 light years away in another solar system...

    Astronomers find super-Earth using amateur, off-the-shelf technology

    Astronomers announced today that they have discovered a "super-Earth" orbiting a red dwarf star 40 light-years from Earth. They found the distant planet with a small fleet of ground-based telescopes no larger than those many amateur astronomers have in their backyards. Although the super-Earth...

    Peculiar, Junior-Sized Supernova Discovered by New York Teen

    2009-06-11 In November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. Additional observations determined that the object, called SN 2008ha, is a new type of stellar explosion, 1000 times...
