Nasa releases images of entire universe – and we're over the moon

Image from Nasa is a mosaic of images covering the entire sky as observed by the Wide-field Infrared Survey Explorer 

 

 

The Fermi paradox, named for the physicist Enrico Fermi, goes something like this: given how big and old the universe apparently is, there is bound to be alien life out there somewhere. But given that the universe is so big and so old, if there's alien life out there, why haven't we earthlings encountered it yet? The experiment certainly has run its course for long enough now.

The paradox may play in the mind of anyone who catches an astounding image released this week by Nasa of … the entire universe. The full-size image (and what warrants full size as much as an image of the universe?) is here.

The image is actually a mosaic of the images covering the entire sky as observed by the Wide-field Infrared Survey Explorer (Wise). Wies is an unmanned satellite carrying an infrared-sensitive telescope. As with a flat map of the Earth's surface, the right and left edges of this oval shape are the same location in the sky. The bright belt is the Milky Way galaxy. Nasa explains:

The Milky Way is shaped like a disc and the solar system is located in that disc about two-thirds of the way out from the centre. So we see the Milky Way as a band running through the sky. As we look toward the centre of the Galaxy we are looking through more of the disc than when we are looking at large angles away from the centre, and you can see a noticeable increase in stars (coloured blue-green) toward the centre of the image … Residuals of the planets Saturn, Mars, and Jupiter are visible in this image as bright red spots off the plane of the galaxy at the 1.00, 2.00 and 7.00 positions, respectively.

The Space Sciences Laboratory at Berkeley has helpfully labeled some of the heavenly bodies visible in the image. Our favorites include Andromeda Galaxy, The Pleiades, Sombrero Galaxy, Heart and Soul Nebula and, of course, the Fornax Cluster. Just look at that up there. Look at that.

Looking For Aliens? Astronomers Unveil New Technique To Measure Pull Of Gravity

Damn but looking for alien civilizations is getting personal.  Now scientists are trying to work how obese aliens on a planet might be.....I think I got that right?

Discovering Alien Life May Be Possible As Astronomers Unveil New Technique To Measure Pull Of Gravity

 

Astronomers have discovered a new technique to measure the pull of gravity, which could help us find alien life.

According to a team from the University of Vienna, this latest advance helps scientists better determine whether distant stars could be harbouring life.

"If you don't know the star, you don't know the planet," said study co-author, Professor Jaymie Matthews.

"The size of an exoplanet is measured relative to the size of its parent star.


"If you find a planet around a star that you think is Sun-like but is actually a giant, you may have fooled yourself into thinking you've found a habitable Earth-sized world.

"Our technique can tell you how big and bright is the star, and if a planet around it is the right size and temperature to have water oceans, and maybe life."

What they are essentially measuring is the surface gravity of a star - an indication of how much you would weigh on that star.

The technique has been dubbed, "auto correlation function timescale technique” and it uses subtle variations in the brightness of distant stars recorded by satellites like Canada's MOST and NASA's Kepler missions.

By understanding the nature of other stars, we might be able to "find other planets like our Earth,” explained lead author Thomas Kallinger from University of Vienna.
