Watch: How Earth will look in 250 million years

Earth’s outer shell is divided into multiple plates that slowly glide over the mantle. The movement of these plates slowly changes Earth’s surface over time by merging, or separating, continents. 250 million years from now, consistent with the supercontinent cycleNotes 1, there will be a possible future supercontinent called Pangaea Ultima. Hypothesized by Christopher Scotese, a geologist at the University of Texas at Arlington, Pangaea Ultima earned its name from its similarity to the previous Pangaea supercontinent, which was formed about 335 million years ago, and began to break apart about 175 million years ago. Here is a beautiful video published by the Tech Insider channel showing the formation of this supercontinent.

The Earth is 18 Galactic Years Old

How old is the Earth? This question preoccupied first philosophers, then scientists, for many centuries. Today, we know that the age of the Earth is approximately 4.54 billion years, with an error range of about 50 million years (4.54 × 109 years ± 1%). This number is based on evidence from radiometric dating of the oldest-known terrestrial rocks as well as lunar rock samplesNotes 1 and meteorites.

Watch: Equinoxes and Solstices from Space

Every year, there are two Equinoxes (around March 20 and September 23) and two Solstices (on about June 21 and December 21). Spring and autumn start with an equinox – daylight and night time are of approximately equal duration all over the Earth during Equinoxes. Winter and summer start with a solstice – daylight time is the longest of the year during the summer solstice, and obviously, the night time is the longest during the winter solstice.

The hottest place in the Universe exists on Earth

The hottest place in the Universe exists here on Earth, like the coldest place in the Universe. Both these extreme temperatures are not natural, they are human-made. The coldest temperature was achieved in the German physicist and professor of physics Wolfgang Ketterle’s laboratory at the Massachusetts Institute of Technology (MIT). The hottest temperature, also recognized by the Guinness Book of World Records, was achieved at CERN’s Large Hadron Collider (LHC).

The coldest place in the Universe exists on Earth

It may sound strange, but the coldest place in the Universe is not anywhere in the vast, cold outer space – it exists here on Earth. Well, it is not actually a natural place you can come across. It is in a laboratory in M.I.T. (Massachusetts Institute of Technology).

Point Nemo – The Spacecraft Graveyard

In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place that humans live – in fact there is no land there – not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called as “Oceanic pole of inaccessibility”.Notes 1

Animation – Earthquakes Between 2001 and 2015

The American scientific agency within the United States Department of Commerce, National Oceanic and Atmospheric Administration (NOAA) published an animation on youtube showing the Earthquakes of the First 15 Years of the 21st Century (between January 1, 2001 and December 31, 2015). The animation shows every recorded earthquake in sequence as they occurred at a rate of 30 days per second. It is based on the new SOS dataset of all the earthquakes in that period from the US NWS Pacific Tsunami Warning Center.

Total Solar Eclipse 2017 Images From Space

On Monday, August 21, an estimated 2 million to 7.4 million Americans traveled to see the first total solar eclipse in 99 years to go coast to coast in the United States, which went from Lincoln Beach, Oregon, to Charleston, South Carolina. But, some of them were unlucky, as the weather was overcast in some places. But, luckily for them (and for us), NASA captured some amazing and beautiful images of the eclipse and published them on their web site.
