An amazing video of our beautiful Blue Marble from the International Space Station, titled “ISS over New Zealand”, published by the NASA Crew Earth Observations channel.

As soon as NASA’s Cold Atom Laboratory (CAL) began producing ultra-cold atoms, the International Space Station (ISS) became the coldest place in the known universe. The formation of a Bose-Einstein condensate, a fifth state of matter occurred in NASA’s Cold Atom Laboratory (CAL) at a temperature of 130 nanoKelvin, or less than 10 billionth of a degree above Absolute Zero. Absolute zero, or zero Kelvin, is equal to minus 459 degrees Fahrenheit or minus 273 Celsius. Previously, the record-cold was achieved in Prof. Wolfgang Ketterle’s laboratory at M.I.T. (Massachusetts Institute of Technology): half-a-billionth of a degree above absolute zero.

Russia’s Progress 70 resupply spacecraft set a milestone for International Space Station operations when it arrived in a record time: just three hours and 40 minutes, or only two Earth orbits (of the ISS). The uncrewed spacecraft delivered the cargo which includes 530 kg of propellant, 52 kg of oxygen gas, 420 kg of water and 1,565 kg of “dry” cargo such as food and other equipment to the space station.

On April 24, 1990, Hubble Space Telescope was launched into low Earth orbit from space shuttle Discovery (STS-31). It orbits the Earth at an altitude of about 350 miles (560 kilometers). For a comparison, the International Space Station (ISS) maintains an orbit with an altitude of between 205 and 270 miles (330 and 435 kilometers). The telescope is 43.5 feet (13.2 meters) long, weighs 24,500 pounds (11,110 kilograms).

NASA Astronaut Ricky Arnold published an amazing “selfie” from space on his Twitter account saying “An amazing view of our one and only planet”. He took this selfie during the May 16, 2018 spacewalk to perform upgrades on the International Space Station. We can see the Earth, the beautiful blue marble, reflecting on his helmet’s visor.

Where is the coldest known place in the Universe? It may sound strange, but today, it is here on Earth: in 1995, in a laboratory in M.I.T. (Massachusetts Institute of Technology), the German physicist Wolfgang Ketterle and his colleagues have cooled a sodium gas to the lowest temperature ever recorded, only half-a-billionth of a degree above absolute zero.

You can help NASA on some projects: for instance, citizen scientists helped NASA identify an aurora-related celestial phenomenon, now called STEVE. Want to become a citizen scientist? You can find projects on NASA website.

NASA Astronaut Andrew Jay “Drew” Feustel, who is currently living and working aboard the International Space Station, published a photo on his Twitter account with a replica of the “Moon Landscape” drawing by Holocaust victim Petr Ginz to honor Holocaust Remembrance Day (Yom HaShoah). The replica of the painting was first flown in space by Ilan Ramon (June 20, 1954 – February 1, 2003), the first Israeli astronaut for NASA. Ramon has died in the re-entry accident of STS-107, the fatal mission of the Space Shuttle Columbia. Ilan Ramon’s mother and grandmother were Auschwitz survivors, and his grandfather and other family members perished in Nazi death camps.

How far away can you get from everybody else on Earth? A video, published by RealLifeLore channel on YouTube answers this very question. The answer is “actually quite far”, there are a lot of extremely remote places left in the world and some of them have actually yet to be reached by anybody in all of history. The world is an enormous place. Here are the most remote places on Earth.

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.
