On September 20, 2016, Argentinian amateur astronomer Victor Buso was testing his camera-telescope setup. He pointed his Newtonian telescope at NGC613, a barred spiral galaxy located some 67 million light-years away in the southern constellation of Sculptor. Then he started taking a series of short-exposure photographs. To ensure his new camera was functioning properly, he …

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 …

As a result of global warming, the seas warm and ice melts. Naturally, Earth’s oceans have risen steadily – or at least, it was thought so. According to a new study based on 25 years of NASA and European satellite data, rather than increasing steadily, global sea-level rise has been accelerating in recent decades. If this trend …

A breathtakingly beautiful photo of a historical moment: NASA Astronaut Robert L. Stewart untethered above the Earth during the first Manned Maneuvering Unit (MMU) exercise. The photo was taken on February 7, 1984, during the EVA 1 (Extravehicular activity) of STS-41-B, the tenth NASA Space Shuttle mission, and the fourth flight of the Space Shuttle …
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 …
The Lion (Panthera leo) is the second-largest cat in the world, after the tiger. The lion and tiger are closely related and they share a very similar body type. As its scientific name suggests, Lion is one of the five members of the Panthera genus (see notes 1). Here are 20 amazing lion facts.
One of the most interesting photos in history: the entire Earth clearly reflects off the side of a… car!
Good news for the search for extraterrestrial life: the TRAPPIST-1 System might be rich (very rich!) in water and all of the planets are mostly made of rock. Using data from NASA’s Spitzer and Kepler space telescopes, researchers calculated the densities of TRAPPIST-1 planets more precisely than ever, and they determined that all of the …

This will go down as one of the greatest videos in history, and you must share it with everyone you know. It is one of the great achievements our species has ever done. SpaceX’s Falcon Heavy test flight was successful and the rocket’s upper stage, together with Elon Musk’s electric sports car Tesla and the …
