Bizarre sea slug is half plant, half animal

 

 

It looks like any other sea slug, aside from its bright green hue. But the Elysia chlorotica is far from ordinary: it is both a plant and an animal, according to biologists who have been studying the species for two decades.

 

Not only does E. chlorotica turn sunlight into energy ? something only plants can do ? it also appears to have swiped this ability from the algae it consumes.

Awesome!

Thunderstorms Shoot Beams of Antimatter Into Space

 

 

Forget about gamma rays from the hearts of distant galaxies. Scientists now believe gamma rays, as well as beams of energetic particles of antimatter, are common components of lightning storms right here on Earth.

 

In 2009, researchers announced that NASA?s Fermi Gamma-ray Space Telescope had, for the first time, detected gamma rays produced by antimatter generated in terrestrial lightning storms.

'Second sun' on its way

 

 

The Earth could find itself with a 'second sun' for a period of weeks later this year when one of the night sky's most luminous stars explodes, scientists have claimed.

 

The supernova could provide the biggest light show since Earth was formed, and will be so bright that night will become like day for one or two weeks, experts said.

now that would start fucking people's brains over if they didn't hear about it...

 

except from RTFM

 

Brad Carter, senior lecturer of physics at the University of southern Queensland in Australia, said the explosion could take place before the end of the year ? or indeed at any point over the next million years.

 

Give us a better estimate

yeah for sure, its a bit vague. I wonder what side effects of such a close supernova would be. Hopefully no gamma ray bursts etc in our direction!

Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists

 

When we look out into the Universe, the stuff we can see must be close enough for light to have reached us since the Universe began. The universe is about 14 billion years old, so at first glance it's easy to think that we cannot see things more than 14 billion light years away.

 

That's not quite right, however. Because the Universe is expanding, the most distant visible things are much further away than that. In fact, the photons in the cosmic microwave background have travelled a cool 45 billion light years to get here. That makes the visible universe some 90 billion light years across.

 

That's big but the universe is almost certainly much bigger. The question than many cosmologists have pondered is how much bigger. Today we have an answer thanks to some interesting statistical analysis by Mihran Vardanyan at the University of Oxford and a couple of buddies.

Runaway Star Plows Through Space

A massive star flung away from its former companion is plowing through space dust. The result is a brilliant bow shock, seen here as a yellow arc in a new image from NASA's Wide-field Infrared Survey Explorer, or WISE.

 

The star, named Zeta Ophiuchi, is huge, with a mass of about 20 times that of our sun. In this image, in which infrared light has been translated into visible colors we see with our eyes, the star appears as the blue dot inside the bow shock.

 

Zeta Ophiuchi once orbited around an even heftier star. But when that star exploded in a supernova, Zeta Ophiuchi shot away like a bullet. It's traveling at a whopping 54,000 miles per hour (or 24 kilometers per second), and heading toward the upper left area of the picture.

Holographic television by 2012

 

Television and laptop makers are trying to make 3D displays which can be watched without wearing 3D glasses - the thought being that the glasses may put a lot of people off 3D TV in the home.

 

But there are rumblings which suggest that 3D may have bigger problems - with holographic TV planned to be its successor.

 

On a holo-TV, images will be projected into the middle of a room as a "cloud" that can be viewed from every angle without 3D glasses, and manufacturers hope they could go on sale in 2012.

 

Spencer Kelly took a look at an early prototype.
