Good news for the search for extraterrestrial life: the TRAPPIST-1 System might be rich (very rich!) in water and all of the planets are mostly made of rock. Using data from NASA’s Spitzer and Kepler space telescopes, researchers calculated the densities of TRAPPIST-1 planets more precisely than ever, and they determined that all of the planets are mostly made of rock. Additionally, some have up to 5 percent of their mass in water, which is around 250 times more than the oceans on Earth. Researchers published their findings in a recent study in the journal Astronomy and Astrophysics titled “The nature of the TRAPPIST-1 exoplanets” .

This will go down as one of the greatest videos in history, and you must share it with everyone you know. It is one of the great achievements our species has ever done. SpaceX’s Falcon Heavy test flight was successful and the rocket’s upper stage, together with Elon Musk’s electric sports car Tesla and the dummy “Starman”, are on their way to Mars.
When Falcon Heavy lifted off, it became the most powerful operational rocket in the world by a factor of two. This rocket that may one day carry humans to the Moon or Mars! With the ability to lift into orbit nearly 64 metric tons (141,000 lb)-a mass greater than a 737 jetliner loaded with passengers, crew, luggage and fuel-Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost. Falcon Heavy draws upon the proven heritage and reliability of Falcon 9.

Spacewalking or Extravehicular activity (EVA) is any activity done by an astronaut or cosmonaut outside a spacecraft beyond the Earth’s appreciable atmosphere (a moonwalk is also an EVA). The first skywalker was the Soviet cosmonaut Alexey Arkhipovich Leonov. He became the first human to conduct an extra-vehicular activity (EVA) on March 18, 1965; exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk. Since this very short EVA, a lot of astronauts/cosmonauts spent many hours outside their spacecraft, mostly for maintenance missions. Here are the top 20 longest spacewalks in history.

During the Russian cosmonauts Anton Shkaplerov and Expedition 54 Commander Aleksandr Misurkin’s spacewalk on February 2, 2018, NASA astronaut Mark T. Vande Hei published a photo on his twitter account and asked his followers that “Can you find the space-walker’s legs in this photo?” Vande Hei added “Russian spacewalk continues!”

A small boy hauls enthusiastically on his fishing rod. The line flies up and a needle-spined fish strikes him in the eye. Desperate to stay outdoors, he ignores the pain, but his sight deteriorates over the following months. He continues to pursue his love of nature but, now blind in one eye, he is confined to studying creatures that are easy to see: insects. He grows to become the global authority on ants, and in later life is given the moniker ‘the father of biodiversity’.

Today (January 31), with popular terms, there was a “super blue blood moon”. It will be the first full total moon eclipse since September 27/28, 2015. What’s more, it was the first Blue Moon / Blood Moon visible from the United States since 1866.
UPDATE: NASA is live now, saying “We’re live online with views of the #SuperBlueBloodMoon from @UHawaiiNews.” (Click here to watch the live stream)

NASA astronaut Randy “Komrade” Bresnik, the commander of the Expedition 53 (the 53rd expedition to the International Space Station) has published a beautiful video on his twitter account titled “Through the eyes of a spaceman: One World Many Views”. In the video, Bresnik shared photos of places he’d visited on Earth alongside photos of the same locations he snapped from space. He also wrote: “You don’t have to be in outer space to experience the beauty of our home planet. Capture the beauty of a moment, or the excitement of an instant, and share it with others.”

An amazing time-lapse video of Earth from the geostationary orbitNotes 1. The video was generated from the images taken by Japanese weather satellite Himawari 8, which takes a photo of Earth every 10 minutes. Himawari 8 is the 8th of the Himawari geostationary weather satellites operated by the Japan Meteorological Agency.
