New Discovery of 'Dark Matter' Galaxy

New Discovery of 'Dark Matter' Galaxy

     Astronomers have discovered a galaxy as big as the Milky Way that consists almost entirely of dark matter, a mysterious and invisible substance that scientists have been trying to figure out for decades. Only one-hundredth of one percent of the galaxy is ordinary, visible

matter like stars and planets. The other 99.99 percent of the stuff in this galaxy can't be seen.

No one really knows what dark matter is made of, but scientists believe it exists because they can see the effects of its gravity on other things in space. Whatever it may be, about 80 percent of the mass in the universe is dark matter. ...

Dark Matter Could Send Asteroids Crashing into Earth

      Dark matter could sling lethal meteors at Earth, potentially causing mass extinctions like the cataclysm that ended the Age of Dinosaurs, Harvard scientists say.

Physicists think the mysterious, invisible substance called dark matter makes up five-sixths of all matter in the universe. It was first detected by the strength of its gravitational pull, which apparently helps keep the Milky Way and other galaxies from spinning apart, given the speeds at which they whirl.

Scientists have recently suggested that a thin, dense disk of dark matter about 35 light-years thick lies along the central plane of the Milky Way, cutting through the galaxy's disk of stars. The sun travels in an up-and-down, wavy motion through this plane while orbiting the center of the galaxy.

Researchers suggest this disk of clouds and clumps made of dark matter might disturb the orbits of comets in the outer solar system, hurling them inward. This could lead to catastrophic asteroid impacts on Earth, of the kind that likely ended the Age of Dinosaurs . . ..

Bell to open the phone lines and listeners' minds to debunk and declassify conventional wisdom in an uncensored, unscripted forum
     NEW YORK, July 30, 2013 /PRNewswire/ -- Sirius XM Radio (NASDAQ: SIRI) announced today it will be the exclusive home to legendary radio personality Art Bell, marking the return of the trailblazing late night host to radio with a new, expanded live, nightly call-in show on which he will explore the paranormal, unexplained and more with expert guests and listeners nationwide.

Art Bell's Dark Matter will debut in fall 2013 on Indie, SiriusXM channel 104, airing nightly from 10:00 pm – 1:00 am ET (7:00 – 10:00 pm PT). Bell will host the show from his home studio in Pahrump, Nevada—near the storied Area 51—opening the phones lines and inviting listeners and expert guests to join his uncensored, unscripted nightly conversation about a wide variety of topics including: the paranormal, near-death experiences, quantum physics, extraterrestrial life and the unusual.

A 2008 inductee to the National Radio Hall of Fame, Bell was one of the top five most listened-to talk hosts in America when he was syndicated weeknights from 1993-2003, sharing the top rankings with Howard Stern, Dr. Laura and Rush Limbaugh, with as many as fifteen million listeners on 500 radio stations. Howard Stern and Dr. Laura are also exclusively heard on SiriusXM.

"SiriusXM is the perfect fit for me and my new show Art Bell's Dark Matter," said Art Bell. "Though invisible, dark matter accounts for gravitational forces observed in the universe—expect these forces to be at work in the uncensored, unrestricted creative arena of satellite radio, a medium with truly extraterrestrial reach."

"We are excited to be the exclusive home of Art Bell, who has captivated a nation of listeners throughout his career with his intelligent and inquisitive, yet entertaining, style," said Scott Greenstein, President and Chief Content Officer, SiriusXM. "Art Bell left terrestrial radio after the biggest possible successes. We are honored that Art now wants to work with SiriusXM to write his next chapter; his vision takes advantage of our best strengths and his new show will be uncensored, unrestricted, uncluttered and utterly unique. With his return to radio on SiriusXM, he will be able to reach millions of longtime listeners and new fans everywhere in the nation."

Bell started in radio at age thirteen when he became a licensed amateur radio operator, a license and interest that he holds to this day. He hosted radio shows while serving in the Air Force in Vietnam, became an engineer when he returned to the U.S., and returned to the airwaves with a late night show on a Las Vegas radio station that ultimately became his nationally syndicated show "Coast to Coast AM."

Art Bell's Dark Matter will be available on SiriusXM On Demand after it airs for subscribers listening via the SiriusXM Internet Radio App for smartphones and other mobile devices or online at siriusxm.com.

Dark Matter Evidence: Scientists Find Signs Of 'Smoking Gun' In Universe's Greatest Mystery | VIDEO

Dark Matter Possibly Found,  Scientists Announced Today

     The first results from the most costly experiment ever conducted in space have begun to unravel one of the universe's greatest mysteries.

The £1.32 billion Alpha Magnetic Spectrometer (AMS), attached to the outside of the International Space Station, is designed to shed light on the nature of dark matter.

Making up around 26% of the universe, this is the mysterious "stuff" that cannot be seen or detected directly but which binds the cosmos together.

Until now scientists have only been able to theorise the existence of dark matter. Its ghostly presence around galaxies exerts a gravitational effect that can be measured, but what it is made of is still a matter of speculation.

The AMS results announced by the American space agency Nasa show it has made detections consistent with dark matter colliding with itself and 'annihilating' - the so-called "smoking gun" of dark matter. . . .
