What would Antarctica look like if all its ice melted

Have you ever wondered what would Antarctica look like if all its ice melted? This may seem extraordinary and unlikely, but, this has actually happened in the past. In fact, there have been no major ice sheets over the South Pole for most of the Earth’s history.

In the video below, NASA Goddard strip away Antarctic ice to reveal a new, and much more detailed map of the bedrock below. This map, called Bedmap2, was compiled by the British Antarctic Survey and incorporates millions of new measurements, including substantial data sets from NASA’s ICESat satellite and an airborne mission called Operation IceBridge.

Mont Blanc – 365 Gigapixel Panorama (World’s Largest Photo)

An international team led by the Italian photographer Filippo Blengini created a 365-Gigapixel Panorama of Mont Blanc, Europe’s highest mountain, and the gigantic image becomes the World’s largest photoSee Note. The previous record-holder, published in 2013, was a 320-gigapixel shot of London, taken from atop the BT Tower.

Earth Between the Rings of Saturn

A beautiful image published by NASA, taken by the unmanned Cassini-Huygens spacecraft, shows the Earth between the rings of Saturn. The image is taken on April 12, 2017.

“Consider again that dot [Earth]. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.” Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space

Lights of Human Activity (Earth from Space at Night)

The first new global map of Earth from space at night since 2012 has been released by the NASA scientists. The nighttime look of our planet is dubbed the “Black Marble”. But why?

On December 7, 1972, the crew of Apollo 17 spacecraft en route to the Moon took a photo of Earth from the space, at a distance about 45,000 kilometers (28,000 miles). This image, with the official NASA designation AS17-148-22727, became known as “The Blue Marble”.

Leaving Solar System at the Speed Of Light

Our Solar system is big, and vast, despite it is really small compared to our galaxy, not to mention the complete universe. To put this into a perspective, you can think yourself as a photon emitted by the Sun. It takes about 8 minutes to reach the Earth after a photon has been emitted from the Sun’s surface. And it takes 5 hours to get out to Pluto from the Earth. The edge of the Solar System is far beyond the orbit of Pluto.

Great American Total Solar Eclipse 2017

There will be a total solar eclipse on Monday, Aug. 21, 2017, and the United States will be the best country to watch. It will be also the first total solar eclipse to go coast to coast in the U.S. in 99 years. From Oregon to South Carolina, 70-mile Moon-shadow will race across the U.S. and it will completely block out the Sun for a few minutes. It’s still more than seven months away, but hotels already are selling out as people prepare for the rare and amazing event.
