Dying Star Screams As It Falls Into Black Hole
As a doomed star spirals closer and closer to a black hole that's about to gobble it up, it lets out periodic bursts of light that scientists liken to dying screams, astronomists say.

 The star is falling into a gigantic black hole in the center of a distant galaxy that lies 3.9 billion light-years away in the direction of the constellation Draco. As the remains of the star get pulled in, it releases blips of light about every 200 seconds, with occasional lags.

 "You can think of it as hearing the star scream as it gets devoured, if you like,"

That's horrible.  Makes me think of the little scream a crab emits as you toss it into the boiling pot of water

NASA's Dawn Spacecraft Hits Snag on Trip to 2 Asteroids
A NASA spacecraft orbiting the huge asteroid Vesta has suffered a glitch last week, but mission controllers say it will not affect plans for its upcoming trip to Ceres, the largest asteroid in the solar system.

Very cool ion engines that thing has.  Let's hope it continues it's research work.

Meteor explodes over Great Britain with violent force
We just had the perseids with a low moon here.  For the first time in years it was a great meteor shower!  You have to get out of the lights of the cities for proper stargazing unfortunately for most of us

Northern Lights Blaze Up After Big Sun Storm
I've been in northern Alaska in the dead of winter and have to say that teh Aurora/northern lights are unwordly.  They should be on your bucket list.

Standing around on the side of a road in your running gear when it's 20 below....priceless (and a tad painful in places unmentionable)

Voyager 1 Spacecraft Farther From Solar System's Edge Than Thought
Voyager 1 launched 35 years ago today, September 5.  It's still working, still controllable by Nasa, along with Voyager 2.

Voyager 1, which left Earth on Sept. 5, 1977, is about 11.3 billion miles (18.2 billion kilometers) from the sun. Meanwhile, Voyager 2, which launched 16 days earlier on a longer trajectory, is approximately 9.3 billion miles (14.9 billion km) from the sun.

Now that's getting some performance out of a piece of equipment.  No repairs, no replaced batteries.  It's almost impossible to picture in todays' throw away wiorld.

This evening, an asteroid the length of three football fields will buzz by Earth at a rate of 7 miles per second.

The asteroid called 2012 QG42 is about to get its close-up.

A month ago, scientists weren't even aware it existed. But it's now on the radar, and viewers can watch it pass by Earth from the convenience of the Web. No astronomy lessons necessary.

Although tonight's flyby is harmless, the asteroid has been named "potentially hazardous" by the Minor Planet Center. That means it's not dangerous, at least not yet. But it could pose problems in the future.

Meanwhile, this close encounter with the space rock will be a comfortable seven and a half times the distance to the moon?1.8 million miles to us Earth-bound folk?at its closest to us, which will be this evening.
 The asteroid won't be viewable by the naked eye or low-powered telescope.

Nuts.  I thought it would be close
