Nicknamed “Paddle-Wheel Satellite”, NASA’s Pioneer 5 probe was launched on March 11, 1960, from Cape Canaveral Air Force Station.

On March 8, 2022, Taikonaut Wang Yaping celebrated International Women’s Day from China’s Space Station Tiangong by delivering a special message to the world.
Antarctica is the coldest continent in the world, holding the record for the lowest temperature ever recorded on Earth. Even more surprisingly, its average temperature is far lower than that of the Arctic. Despite both the Arctic and Antarctica being located at the poles, the Antarctic ice sheet is significantly larger and thicker than the ice found in the Arctic. So, why is Antarctica so much colder than the Arctic? Here are the key reasons behind this extreme cold.
E=mc2 is probably the world’s most famous equation. It means “Energy equals mass times the speed of light squared.” The formula basically implies that a small amount of rest mass corresponds to an enormous amount of energy, and that’s the physics behind nuclear fission or nuclear fusion. In this amazing video, Albert Einstein explains his famous formula in his own voice.
Researchers from the Big Data Institute at the University of Oxford in England used DNA analysis to create the largest human family tree ever, dating back 100,000 years. They published their study titled “A unified genealogy of modern and ancient genomes” in the journal Science.
Discovered on January 6, 2015, Kepler-442b is a near-Earth-sized exoplanet. Most probably it is a rocky planet and it orbits its star, Kepler-442, within the habitable zone. According to some sources, including Wikipedia, it is an even more habitable planet than Earth. But, that’s not the case, and this claim is just an inaccurate interpretation of a 2015 study. Here’s why.
To keep Earth from dangerous ongoing global warming, the world is looking for an energy source without CO2 emissions. There is actually a dream candidate: successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy.
It’s a well-known fact that light slows down in water or glass, or any other transparent medium. Even more interestingly, after leaving that medium, it goes back to its original speed. Yes, it speeds up! But, how could that happen? Why does light slow down in water or glass, and why and how does it increase its speed once it left the medium? Where does that extra energy come which speeds it up again?
It’s like the Google Earth of Evolution: OneZoom Tree of Life Explorer enables you to navigate all the leaves and branches of life on Earth, and how all the species are related. By using the tool, you can go back (or forward) in time via common ancestors.
This stunning video by “Epic Spaceman” shows how big the Orion Nebula is compared to our Sun. According to the creator, it took 6 months to prepare this video.
