Hubble photographs the farthest-ever view of the universe – it’s amazing

Prepare to be blown away with this short video and the images from Hubble. We are a pale blue dot.

 

 

And the original story from NASA:

Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of Hubble photographs taken of a patch of sky. The XDF is a small fraction of the angular diameter of the full moon…and contains about 5,500 galaxies. The faintest galaxies are one ten-billionth the brightness of what the human eye can see.

 

The NASA images they reference:

Google adds educational Street Views – Antarctica with exploration outposts, penguins, and more

One of the focuses of this special addition to Google Maps is to teach users about the history of Antarctic exploration and the people who first set up shop in this bleak environment.

Here’s what Google’s technical program manager for Street View Alex Starns wrote in a blog post:

In the winter of 1913, a British newspaper ran an advertisement to promote the latest imperial expedition to Antarctica, apparently placed by polar explorer Ernest Shackleton. It read, “Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in event of success.” While the ad appears apocryphal, the dangerous nature of the journey to the South Pole is certainly not–as explorers like Roald Amundsen, Robert Falcon Scott and Shackleton himself discovered as they tried to become the first men to reach it.

Partnering with the Polar Geospatial Center at the University of Minnesota and the New Zealand Antarctic Heritage Trust, Google has added 360-degree images of many historic spots, including the South Pole Telescope, Shackleton’s and Scott’s small wooden huts, Cape Royds Adelie Penguin Rookery, and the Ceremonial South Pole.

“They were built to withstand the drastic weather conditions only for the few short years that the explorers inhabited them,” Starns wrote, “but remarkably, after more than a century, the structures are still intact, along with well-preserved examples of the food, medicine, survival gear and equipment used during the expeditions.”

Hubble discovers another moon orbiting Pluto – that’s two in the last year

A team of astronomers using NASA’s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.

The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.

“The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute in Mountain View, Calif.

The discovery increases the number of known moons orbiting Pluto to five.

The Pluto team is intrigued that such a small planet can have such a complex collection of satellites. The new discovery provides additional clues for unraveling how the Pluto system formed and evolved. The favored theory is that all the moons are relics of a collision between Pluto and another large Kuiper belt object billions of years ago.

The new detection will help scientists navigate NASA’s New Horizons spacecraft through the Pluto system in 2015, when it makes an historic and long-awaited high-speed flyby of the distant world.
