-(Natural News) Liquid water had long since deserted the surface of Mars, leaving only the faint marks of its passage in the form of dried-out channels, lake-beds, and valleys. But researchers said that the Red Planet might harbor flowing water hundreds of meters underground. Previous studies have indicated that the Martian south pole contained lakes […]

-(Natural News) Mars might be a dry world now, but researchers recently described a different landscape more than a billion years ago. Back then, the Red Planet produced mighty waterways that dwarfed the Amazon River, the broadest body of water on Earth today. Furthermore, the ancient Martian rivers might have lasted much longer than expected. […]

-(Natural News) A recent study by European researchers strengthened the case for seasonal spikes of methane in Mars. First discovered by NASA’s Curiosity rover in 2013, the latest methane spikes were confirmed by orbiting spacecraft. In 2019, Curiosity discovered that the methane levels in the Martian atmosphere changed from season to season. The gas hit its peak […]

-(Natural News) Several million years ago, a binary star might have zipped past another pair of younger stars, thereby disrupting the orbit of a newly formed planet in the latter system. The researchers who made this astonishing discovery thought that this ancient stellar flyby might help explain the weirder parts in our solar system. Earlier […]

-(Natural News) An international team led by Goethe University in Germany has successfully converted xenon ions into the heavy element cesium. The results, which appeared in Physical Review Letters, was the first to replicate this phenomenon in a controlled environment. A matter of stardust Nucleosynthesis refers to the creation of atomic nuclei, or broadly defined, the elements. According […]

-(Natural News) Most Hollywood films that revolve around asteroid impacts end with the heroes successfully blowing up the incoming space rock in the nick of time. But researchers warn that a potential killer asteroid hurtling toward Earth is going to be much harder to stop in real life. Like many others before them, the Johns Hopkins […]

-(Natural News) Millions of years ago, asteroids slammed into Mars, possibly delivering loads of the ingredients required for starting organic life on a planet. During the time of the cosmic event, the Red Planet may have possessed plenty of atmospheric hydrogen, which would have helped spur the development of simple organisms. Assuming Mars did have […]

-(Natural News) Researchers have placed their best bets on finding an Earth-like planet on nearly 2,000 stars, meaning these exoplanets might not be as rare as people think. Some of these stars lay within just a few light-years of our solar system. NASA’s Transiting Exoplanet Survey Satellite (TESS) has targeted the stellar candidates. The successor […]

-(Natural News) In school, students are taught that the closest planet to Earth is Venus. However, at a commentary published in Physics Today, experts say that Mercury is actually closest to Earth. Not only that, but Mercury is also closest to other planets in the solar system. The planet closest to Earth most of the […]

-(Natural News) Black holes are well-known massive cosmic events, but you don’t expect them to occur all that often. However, Japanese astronomers discovered a staggering 83 quasars powered by supermassive black holes in the early universe. This discovery is instrumental in understanding how common supermassive black holes were during the universe’s infancy. Supermassive black holes […]
