What would it be like to stand on the surface of another planet? “We The Curious” channel has teamed up with a group of astrophysicists to create a scientifically accurate virtual reality tour of six real exoplanets discovered outside our solar system. The fruit of this collaboration is the video below, in 4K Ultra-HD and …

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 the NASA website.
According to a new study, the Moon might have been formed a thousand years earlier than Earth. The new “synestia theory” suggests a Mars-sized object smashed into the proto-Earth. The “giant impact” vaporized about 10 percent of the rock and liquefied the rest, and created a rapidly spinning donut-shaped mass of vaporized rock called “synestia”. …

According to a new study, microbes like those found in Earth’s deep ocean could potentially thrive in the underground ocean of Saturn’s icy moon Enceladus. Both molecular hydrogen (H2) and methane (CH4) already have been detected in the plume. Researchers have shown that Methanothermococcus okinawensis, a methanogenic archaeon first isolated from a deep-sea hydrothermal vent …

On February 6, 2018, SpaceX successfully tested Falcon Heavy, the most powerful rocket that the American company ever built. When lifted off, it became also the most powerful operational rocket in the world. Powerful rockets like Falcon Heavy may one day carry humans to the Moon or Mars. But there might be an even more important use of powerful …

NASA’s asteroid-sampling OSIRIS-REx spacecraft captured a new Earth-Moon image on Jan. 17, 2018, from a distance of 39.5 million miles (63.6 million kilometers). Spacecraft used its NavCam1 imager to take this photo, as part of an engineering test. In the image, The Earth and the moon are just two bright dots against the vastness of …

It took 27 years, but finally, NASA’s New Horizons spacecraft beat Voyager 1‘s record for being farthest from Earth while capturing images. Taken on December 5, 2017, New Horizons’ image of the open star cluster NGC 3532 (also commonly known as the Football Cluster or the Wishing Well Cluster) became the farthest image ever made by any …
On 15 February 2013, an approximately 20-meter (66 feet) meteoroid (see notes 1) entered Earth’s atmosphere over Russia with a speed of 19.16 ± 0.15 kilometers per second (60,000-69,000 km/h or 40,000-42,900 mph). Its mass is estimated at 7,000 to 10,000 tons, one of the largest meteoroids that entered Earth’s atmosphere in recent history. Then, …

This is how the Crab Nebula was born: in 1054 A.D, a new, very bright star has appeared in Earth’s sky, in the constellation Taurus. Chinese, Japanese, Korean, and Arab astronomers observed the event and noted: “a new bright star emerged in the heavens”. The star was so bright: for nearly three weeks, it was …

An amazing image showing both the Earth and Moon. The distance between our planet and its satellite is actually much more than many would conceptualize. It is 384,400 kilometers (about 239,000 miles) on average, but as usual, our brains cannot deal with such large numbers. Only seeing that distance makes us realize how far even the …
