Hubble finds 10 times as many galaxies as previously thought. NBD.

One of the most fundamental questions in astronomy is that of just how many galaxies the universe contains. The landmark Hubble Deep Field, taken in the mid-1990s, gave the first real insight into the universe’s galaxy population. Subsequent sensitive observations such as Hubble’s Ultra Deep Field revealed a myriad of faint galaxies. This led to an estimate that the observable universe contained about 200 billion galaxies.

The new research shows that this estimate is at least 10 times too low.

Tardigrade

 

Tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations.

74 years later, photos emerge of first sunken seaplanes in Pearl Harbor attack

It’s been 74 years since Japan attacked Pearl Harbor on December 7, 1941, and we’re just now getting a good look at the wreckages of the attack’s first few casualties on the ocean floor.

Twenty-seven Catalina PBY-5 seaplanes that were docked at the Kāne‛ohe Bay, located approximately 20 miles away from Pearl Harbor, were destroyed and sunk to the bottom of the bay in a cloudy, dark murk that prevented photographers from taking proper photos of the wreckage.

More than half of Kepler’s exoplanets are false positive

Yesterday, results were released from an international team led by Alexandre Santerne from Instituto de Astrofísica e Ciências do Espaço, where they measured 129 objects-of-interest identified by Kepler for a period of five years. They did spectroscopic analysis, which means they studied the individual wavelengths of light coming from the star, and expected a false positive rate of about 10-to-20%, which is what most scientists estimated.

But they found, instead, that over half (52%) of the planetary candidates were, in fact, eclipsing binaries, with another three candidates turning out to be brown dwarfs.

Transit: A Photographic Study of The Way Lives Interact During Commuting

“The idea behind ‘Transit’ is to document how people interact and how lives intersect and bind while traveling.” says Remera, a photographer born in Rwanda in 1981. Now living and working in Luxembourg, Remera got into photography through workshops and classes while studying in Strasbourg. Then in 2010, he fell deeper into love with the art form while travelling.

From 0 to 5,000 Planets in Exactly 20 Years

Twenty years ago today, an invisible object circling an obscure star in the constellation Pegasus overturned everything astronomers knew about planets around other stars. No, the fallout was even bigger than that. The indirect detection of 51 Pegasi b—the first planet ever found around a star similar to the sun—revealed that they had never really known anything to begin with.

The oldest galaxies in the universe

More than 12 billion years ago, a sea of stars fell into orbit around a baby black hole, and became a galaxy, one of the first.

The formation of this galaxy, and others like it, was a momentous event in cosmic evolution. This galaxy and its brethren helped to clear hydrogen gas left over from the Big Bang, making our universe transparent to light.

Project Apollo Archive goes up on Flickr

The high resolution originals allow for some breathtaking edits (above).

The original photos (as seen below) are raw and unprocessed  – organized by film magazine.

Contrary to some recent media reports, this new Flickr gallery is not a NASA undertaking, but an independent one, involving the re-presentation of the public domain NASA-provided Apollo mission imagery as it was originally provided in its raw, high-resolution and unprocessed form by the Johnson Space Center on DVD-R and including from the center’s Gateway to Astronaut Photography of Earth web site. Processed images from few film magazines to fill in gaps were also obtained from the Lunar and Planetary Institute’s Apollo Image Atlas.

A massive undertaking to organize 11000+ images. As these photos are in the Public Domain, the photos should be able to be reused without issue.

Digg organized a ‘best-of‘ from the list.

The most instgrammed locations in Canada

Canada’s large land mass and broad longitudinal range make it one seriously awesome place to explore. Given the incredible amount to see and do in each of the 10 provinces and three territories, it could be very difficult to narrow down the list of most popular locations. Fortunately, Instagrammers provided plenty of information – and the best locations have emerged.
