Supermassive black hole swallows star
This illustration released by the journal Nature shows an artist’s conception a surge of X-rays from deep space, which resulted after a black hole tore apart a star. (Amadeo Bachar – AFP/Getty Images) For the first time ever, astronomers say they have witnessed a supermassive black hole devouring a star.
In two papers released Wednesday by the journal Nature, scientists described blasts of radiation so bright and powerful they could only be explained by a luckless, sun-sized star being torn apart by the gravitational forces of a “cosmic monster” — the supermassive black hole.
While scientists say this has happened before, this is the first time they have witnessed the event.
On March 28, a detector on the Earth-orbiting Swift observatory picked up a Read more…
Comet Elenin heads towards Earth…
The ancient Mayan calendar predicts that we will be coming to an end of a cycle in the year 2012. The winter solstice is believed to be the date that the world will end. Lately there has been a lot of buzz about the comet Elenin. The comet is set to come close to earth on October 16th of this year and many believe this will have atrocious affects on the planet. Brooks Agnew, author and host of X-squared radio, tells us why we should care.
Two Comets to Pass Close to Earth in Early October
As mentioned before in previous blogs, Comet Elenin will pass close to Earth in six weeks or so. We had previously talked about the theories out there with this comet. To read them, please click here and here.
For even better treat, on Oct. 7, Comet Honda will brighten to a magnitude 5 in the constellation Leo and favor a horizon view before sunrise for Northern sky observers.
That is not all, Comet Honda will join Comet Elenin, and both will be visible on that morning in the same wide field of view in binoculars and camera lenses, a rare treat with two comets at once! You should be able to get some spectacular photos of this event. I will have to remind you as we get closer to the event so that you can post some pictures for me.

Large Asteroid To Zoom Past Earth In Cosmic Close Call
The third near-earth asteroid of 2011 will pass between the moon and earth later this year, NASA has confirmed.
The 575-foot-wide (175 metres) asteroid, which is more than one and a half times the length of a soccer pitch, will pass within 0.85 lunar distances of the Earth on November 8, 2011.
Discovered on December 28, 2005 by Robert McMillan of the Spacewatch Program near Tucson, Arizona, 2005 YU55 is believed to be a very dark, nearly spherical object.
According to NASA’s Near Earth Object Program: “Although classified as a potentially hazardous object, 2005 YU55 poses no threat of an Earth collision over at least the next 100 years. However, this will be the closest approach to date by an object this large that we know about in advance and an event of this type will not happen again until 2028 when asteroid (153814) 2001 WN5 will pass to within Read more…
Scientists, telescope hunt massive hidden object in space
Some scientists think a brown dwarf or gas giant bigger than Jupiter could be at the outer reaches of the solar system. In this image showing relative size, the white object at the upper left edge represents the sun.
You know how you sometimes can sense that something is present even though you can’t see it? Well, astronomers are getting that feeling about a giant, hidden object in space.
And when we say giant, we mean GIANT.
Evidence is mounting that either a brown dwarf star or a gas giant planet is lurking at the outermost reaches of our solar system, far beyond Pluto. The theoretical object, dubbed Tyche, is estimated to be four times the size of Jupiter and 15,000 times farther from the sun than Earth, according to Read more…
Darkest Planet Found: Coal-Black, It Reflects Almost No Light
Newfound world is off-the-charts dark—and the cause is a mystery, experts say.

It may be hard to imagine a planet blacker than coal, but that’s what astronomers say they’ve discovered in our home galaxy with NASA’s Kepler space telescope.
Orbiting only about three million miles out from its star, the Jupiter-size gas giant planet, dubbed TrES-2b, is heated to 1,800 degrees Fahrenheit (980 degrees Celsius). Yet the apparently inky world appears to reflect almost none of the starlight that shines on it, according to a new study.
“Being less reflective than coal or even the blackest acrylic paint—this makes it by far the darkest planet ever discovered,” lead study author David Kipping said.
“If we could see it up close it would look like a near-black ball of gas, with a slight glowing red tinge to it—a true Read more…

Evidence Found for Undiscovered Comet That May Threaten Earth

A surprise meteor shower spotted in February was likely caused by cosmic “bread crumbs” dropped by an undiscovered comet that could potentially pose a threat to Earth, astronomers announced today (July 27).
The tiny meteoroids that streaked through Earth’s atmosphere for a few hours on Feb. 4 represent a previously unknown meteor shower, researchers said. The “shooting stars” arrived from the direction of the star Eta Draconis, so the shower is called the February Eta Draconids, or FEDs for short.
The bits of debris appear to have been shed by a long-period comet. Long-period comets whiz by the sun very infrequently, so it’s tough to Read more…
