Strange Energy From Galactic Center Bombarding Earth

September 14, 2012 Comments off

Strange particles believed to be emanating from the elusive ‘dark matter’ at the center of the galaxy have been confirmed to be bombarding Earth. Two physicists from the prestigious Department of Physics & Astronomy at University of California discovered more gamma-rays bombarding Earth than believed by astronomers. The stream of electromagnetic radiation (spewed by the process of intensive radioactive decay and other other high-energy emmisions) may be triggering the bizarre mutation of matter and an incredible energy cloud that an astrophysicist says threatens Earth.

According to a groundbreaking investigation conducted by two UC Irvine astrophysicists and submitted to the peer-reviewed American Physical Society journal Physical Review, colliding particles of dark matter may be creating a maelstrom of turbulent energy deep in the heart of the Milky Way Galaxy. Among the particles streaming from the Read more…

Astronomers spot ‘planet’ in Oort Cloud, but are they mistaking Tyche for her sister?

If you grew up thinking there were nine planets and were shocked when Pluto was demoted five years ago, get ready for another surprise. There may be nine after all, and Jupiter may not be the largest.

The hunt is on for a gas giant up to four times the mass of Jupiter thought to be lurking in the outer Oort Cloud, the most remote region of the solar system. The orbit of Tyche, as it is provisionally called, would be 15,000 times farther from the Sun than the Earth’s, and 375 times farther than Pluto’s, which is why it hasn’t been seen so far.

But now scientists believe the proof of its existence has already been gathered by a NASA space telescope, Wise, and is just waiting to be analyzed.

The first tranche of data is to be released in April, and astrophysicists John Matese and Daniel Whitmire from the University of Louisiana at Lafayette think it will reveal Read more…

68 New Earths and 288 New Super Earths: The New Kepler exoplanet data – NASA videos and pictures

February 3, 2011 Comments off

NASA press release on the 1202 new Kepler telescope exoplanets.

Exoplanets classified by size which are:

- 68 Earth-size exoplanets with a radius (Rp) of less than 1.25 Earth radius (Re)
- 288 super-Earth size exoplanets with 1.25 x Re < Rp ≤ 2.0 x Re - 662 Neptune-size exoplanets with 2.0 x Re < Rp ≤ 6.0 x Re - 165
Jupiter-size exoplanets with 6.0 x Re < Rp ≤ 15 x Re - 19
very-large-size with 15.0 x Re < Rp ≤ 22 x Re

“We went from zero to 68 Earth-sized planet candidates and zero to 54 candidates in the habitable zone – a region where liquid water could exist on a planet’s surface. Some candidates could even have moons with liquid water,” said William Borucki of NASA’s Ames Research Center, Moffett Field, Calif., and the Kepler Mission’s science principal investigator. “Five of the planetary candidates are both near Earth-size and orbit in the habitable zone of their parent stars.”

Kepler will continue conducting science operations until at least November 2012, searching for planets as small as Earth, including those that orbit stars in a warm habitable zone where liquid water could exist on the surface of the planet. Since transits of planets in the habitable zone of solar-like stars occur about once a year and require three transits for verification, it is expected to Read more…
