I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#RIP Arecibo telescope — you’ll be missed” OK, 2020 — just stop it already. As might seem appropriate, at the start of 2020, astronomers using Arecibo found an asteroid resembling the head of a person wearing a face mask. The mighty telescope, a victim of multiple disasters, would finally be pushed to the edge and beyond….
“#These are the plastic items that most kill marine animals” How do we save whales and other marine animals from plastic in the ocean?

“#There’s a bunch of undiscovered exoplanets left – math can help us find them” Only 12 light years from Earth, Tau Ceti is the closest single star similar to the Sun and an all-time favorite in sci-fi stories. Habitable worlds orbiting Tau Ceti were destinations of fictional starships like “The Expanse”‘s Nauvoo and “Barbarella”’s vessel….
“#How climate change made Venus impossible to inhabit” We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 450℃ (the temperature of an oven’s self-cleaning cycle) and an atmosphere dominated by carbon dioxide (96%) with a density 90 times that of Earth’s. Venus is a…
“#Newly discovered Jupiter-like world could be the long-sought ‘Planet X’” When the Hubble Space Telescope set its sights toward the binary star system HD 106906, astronomers found a world that could resemble the long-sought Planet X. For the first time, astronomers are able to view a massive Jupiter-like world orbiting far from its parent star….

“#Spiders in space are so unhappy they can’t even build decent webs” Sending spiders to space seems like a good idea (because, science), but arachnids apparently have their own notions about living in space. NASA researchers first sent spiders to space in the 1970’s, so an arachnid-based experiment to raise science awareness among high school…
“#How to spot shooting stars from the Geminid meteor shower this week” On the night of December 13 and the early morning of December 14, the Geminid meteor shower could delight skygazers with a dazzling display of shooting stars. The Geminids are one of the newer meteor showers, first being seen in 1862. These annual…
“#Mysterious cosmic ray electrons have been spotted for the first time” Just beyond the reach of charged particles from our Sun (which is, in some ways, the edge of our solar system), the Voyager spacecraft have witnessed a previously-unseen phenomenon for the first time. The pair of Voyager spacecraft, launched from Earth in 1977, are now…
“#Jupiter and Saturn will be the closest they’ve been in 800 years — here’s how to spot them on Dec. 21” This close encounter of the planetary kind will be easily visible to everyone in the world. The two worlds are already shining brightly in the southwestern sky, soon after sunset. Jupiter and Saturn will draw…
