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.

Now we’re living on a warm, hospitable planet. As Carl Sagan has said “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.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But all things must pass. The life on Earth, even the planet itself, won’t last forever. What’s more, the humans may go extinct before our planet (and probably before the life on it) dies out.
Here some possible (and horrible) ways how planet Earth could die.

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.
