Watch: an amazing time-lapse of the Russian spacewalk over the Atlantic Ocean

The European Space Agency has published an amazing sped-up time-lapse video of the Roscosmos cosmonauts Oleg Kononenko and Sergey Prokopyev during their spacewalk as they floated over the Atlantic Ocean. The video was taken from the European Columbus laboratory.

The two cosmonauts look like working honeybees in the upper-right corner in this sped-up video.

Soyuz MS-11 Launch and Dock as seen from the ISS

On December 3, 2018, a Soyuz MS-11 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan, carrying NASA astronaut Anne McClain, Canadian Space Agency astronaut David Saint-Jacques, and Roscosmos cosmonaut Oleg Kononenko. It was the first manned launch since the Soyuz MS-10 spaceflight aborted shortly after launch on 11 October 2018 due to a failure of the Soyuz-FG launch vehicle boosters. Notes 1 It was the 100th orbital launch of 2018.

Soyuz MS-11 successfully docked to the ISS about six hours after the launch.

European Space Agency astronaut aboard the International Space Station, Alexander Gerst photographed the launch and the docking from the ISS and published these amazing photos on his Twitter account.

Watch: the longest continuous time-lapse from the ISS

To celebrate the 20th birthday of the International Space Station (ISS), the European Space Agency (ESA) published the longest continuous time-lapse video from the orbiting laboratory. In just under 15 minutes, this 4K HD video below takes us from Tunisia across Beijing and through Australia in two trips around the world. You can follow the ISS’s location using the map at the top right-hand-side of the screen alongside annotations on the photos themselves.

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.

Nasa Publishes the first 8k Video from Space

On November 2, 2018, NASA has published the first 8k Ultra-HD video from the space. The video focuses on science efforts aboard the International Space Station (ISS) and features some important investigations and facilities. It also includes a few amazing Earth views from space.

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.

Kessler Syndrome: Space junk can end space exploration, and destroy modern way life

On October 4, 1957, the Soviet Union launched Sputnik 1, the first human-made object to orbit Earth. This event marks the beginning of humanity’s space exploration history. After that, humanity went to the moon, astronauts and cosmonauts performed countless spacewalks, and since the arrival of Expedition 1 on November 2, 2000, the International Space Station station has been continuously occupied. To date, this is the longest continuous human presence in space, having surpassed the previous record of 9 years and 357 days held by Mir. But maybe even more important, we launched thousands of artificial satellites into the Earth’s orbit. These artificial satellites shape our modern life: weather forecasts, broadcasting, communication and GPS are just a few examples. But, there’s a side effect: just like here on the Earth, we are slowly filling the most important part just above us, with junk.  And this junk can end space exploration, and destroy our modern way life. This (very possible) scenario known as the Kessler Syndrome, proposed by the American astrophysicist and former NASA scientist Donald J. Kessler in 1978.

Large Synoptic Survey Telescope will scan the skies for asteroids which threaten Earth

Around 66 million years ago, an asteroid (or a comet) with a diameter of at least 10 kilometers (6 miles) impacted a few miles from the present-day town of Chicxulub in Mexico at around 64,000 kilometers per hour (40,000 mph). The impact triggered a chain of events what it is known today as the Cretaceous-Paleogene (K-Pg) extinction event, also known as the Cretaceous-Tertiary (K-T) extinction, and wiped out three-quarters of the plant and animal species on Earth, including non-avian dinosaurs.

If this Chicxulub impactor happened today, it would wipe out the human civilization. Luckily, events like Chicxulub impact are rare. Asteroids with a 1 km (0.62 mi) diameter strike Earth every 500,000 years on average. But that doesn’t mean we are totally safe. Asteroids with a diameter of at least 140 meters (460 ft) are big enough to cause regional devastation to human settlements unprecedented in human history in the case of a land impact or a major tsunami in the case of an ocean impact.

Watch: Amazing Time-Lapse Video Showing Earth from the ISS

European Space Agency has published an amazing time-lapse video showing the Earth from the International Space Station (ISS). The space agency wrote “Join ESA astronaut Alexander Gerst for a quick flight from the USA to Africa aboard the International Space Station in this time-lapse filmed 12.5 times faster than actual speed.” You can watch that breathtaking video below:

Song of Saturn and Its Moon Enceladus

NASA has published an amazing video titled “Sounds of Saturn: Hear Radio Emissions of the Planet and Its Moon Enceladus”. The analyze of the data from the Cassini Spacecraft’s Grand Finale orbits showed a surprisingly powerful interaction of plasma waves moving from Saturn to its icy moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear, in the same way a radio translates electromagnetic waves into music.

Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument on September 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.
