New Maps Show How We Changed the Earth’s Surface Over the last 25 Years

We, humans, changing the Earth – mostly (almost always) in a bad way. Just over the last 25 years, we have destroyed 10% of the Earth’s wilderness. Now, a new world map created by the University of Cincinnati geography professor Tomasz Stepinski shows how the Earth’s surface has dramatically changed between 1992 and 2015.

Earth, a “Bright Evening Star” as seen from Mars

On January 31, 2014, about 80 minutes after sunset on its 529th Martian day (or sol), NASA’s Curiosity Rover has turned its camera back to home and took this amazing photo of Earth and Moon from a distance of around 99 million miles (160 million kilometers). In the image which has the serial number of PIA17936, Earth can be seen as the brightest point of light in the night sky, a little left of center and our moon is just below Earth.

Watch: Amazing ISS Timelapse of Progress MS-10 launch

This is AMAZING! This wonderful 4K ultra-HD time-lapse video below shows the launch of the Progress MS-10 spacecraft (identified by NASA as Progress 71 or 71P) as seen by the International Space Station (ISS). The resupply mission departed from Baikonur Cosmodrome on November 16, 2018, to deliver fuel and other supplies to the ISS.

How many stars one can see with the naked eye?

The total number of the stars which can be seen with the naked eye is 9,095, according to the Bright Star Catalogue, 5th Revised Edition. Also known as the Yale Catalogue of Bright Stars or Yale Bright Star Catalogue,
the catalog lists all stars of stellar magnitude 6.5 Notes 1 or brighter, which is roughly every star visible to the naked eye from Earth.

The catalog contains 9,110 objects, of which 9,095 are stars, 11 are novae or supernovae, and 4 are non-stellar objects.

We are Destroying the Earth’s Wilderness

We, humans, are destroying the Earth’s wilderness at an incredible pace. Scientists say we have destroyed 10% of Earth’s wildlife habitat in just 25 years. Since 1993, 3.3 million km2 of global wilderness areas, particularly in the Amazon basin (almost 30%) and central Africa (14%) were lost. This is almost twice of the size of Alaska!

What is the mass of the Earth? Scientists used neutrinos to measure

While scanning the interior of Earth using neutrinos, a team of scientists from Spain also used these subatomic particles to measure the mass of the Earth. Their result is in agreement with the current best estimate, which was measured using the value of the gravitational constant (G).

Watch: The Milky Way as You’ve Never Seen It Before

In April 2018, the European Space Agency’s Gaia observatory released its second data catalog, which includes the distances to over 1.3 billion stars. In the video published by the American Museum of Natural History, museum’s astrophysicist Jackie Faherty breaks down why this information is so revolutionary and explains how this information is helping scientists and non-scientists alike understand the universe like never before.
