Russian TV network Russia Today (RT) has released the first 360-Degree Spacewalk Video ever. The video is recorded by the Russian Cosmonauts Sergey Ryazansky and Fedor Yurchikhin outside the International Space Station (ISS) while doing their 7.5-hour spacewalk on August 16, 2017. The video contains breathtaking images of Earth. You can watch the 360-Degree interactive video below.Continue reading “the First-Ever 360-Degree Spacewalk Video”
Crocodiles are aquatic reptiles, and among the most feared carnivores on Earth, because of their size, big powerful jaws and aggressiveness. They are so successful predators – once they were living alongside the dinosaurs. After the Chicxulub impact, which happened around 66 million years ago, the non-avian dinosaurs were gone but crocodiles were managed to survive. Here are top 20 amazing crocodile facts about these fascinating beasts.Continue reading “20 Amazing Crocodile Facts”

While Elon Musk and SpaceX planning to send Humans to Mars as early as 2024, the American global aerospace, defense, security,
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
The billionaire founder of SpaceX, Elon Musk has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. He provided an update on their Mars colonization plan at the International Astronautical Congress (IAC) Notes 1 in Adelaide, Australia this week. Musk plans to send 1 million people to Mars using BFR Notes 2, and “making life multiplanetary”. He has highly ambitious plans, like launching and landing at least two uncrewed cargo ships on Mars as early as 2022.
The newly announced BFR is smaller than the one Musk revealed at the same event last year, 106 meters (348 feet) tall and carrying capacity of 150 tonnes compared to the previous design’s 122 meters (400 feet) and 300 tonnes. But, (naturally) it’s way cheaper than the previously announced version, and according to Musk, “lower cost is the biggest update”. And, still, it is more powerful than any of SpaceX’s or NASA’s other planned rockets.Continue reading ““Making Life Multiplanetary”: Musk reveals a new plan to colonize Mars”
On September 27, BBC has published the prequel of “Blue Planet II”. Like “The Blue Planet”, which was premiered on 12 September 2001, it is narrated by Sir David Attenborough, the English broadcaster and naturalist. The exclusive track developed by the German composer and record producer Hans Zimmer and the English rock band Radiohead.
Launched on October 15, 1997, NASA’s Cassini spacecraft Notes 1 went into orbit around Saturn on July 1, 2004. Since then, it has taken thousands of photos of Saturn, the second-largest planet in the Solar System, its prominent rings, and moons. And on September 15, 2017, Cassini plunged into Saturn’s atmosphere and disintegrated. Here are the 20 most beautiful photos that the spacecraft has sent back to Earth during its 13-year voyage around the gas giant.
Cassini was destroyed by diving into the Saturn’s atmosphere on September 15, 2017. This method of disposal was planned to avoid potential biological contamination of Saturn’s moons, since Titan, Enceladus, and other icy moons of Saturn may harbor oceans and alien life.Continue reading “20 Best Photos of Cassini’s voyage around Saturn”
External cameras on the International Space Station captured views during its overhead passes of Hurricane Irma. Most intense Atlantic hurricane observed in over a decade, Hurricane Irma was an extremely powerful tropical cyclone, which became a Category 5 hurricane on September 5. It reached peak intensity with 185 mph (295 km/h) winds on September 6.
Its category dropped to 3 as it passed along Cuba, but, while crossing over warm waters between Cuba and the Florida Keys, it became stronger again and rose to Category 4 on September 10. Then dropped back to Category 3 by the time it made a second Florida landfall on Marco Island. Hurricane Irma weakened to a Category 2 hurricane later that day. As of September 12, it is not a hurricane anymore, weakened to a tropical storm, and then a tropical depression six days after its peak intensityNotes 1.
About 70,000 years ago, a wandering binary stellar system passed through the Solar System’s Oort cloudNotes 1, within 120,000 AU (0.58 pc; 1.9 ly) of the Sun. 70,000 years is just a blink of an eye compared to the Earth’s age, which is 4.543 billion years. Our ancestors were about to left Africa at that time. The binary system is dubbed as Scholz’s StarNotes 2, after its discoverer. Comets perturbed from the Oort cloud would require roughly 2 million years to get to the inner Solar System. So, in the distant future, some of these comets may hit the Earth and cause mass extinctions, like the “dinosaur killer” Chicxulub impactor which impacted a few miles from the present-day town of Chicxulub in Mexico around 66 million years ago.
