I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Russia wants to return to Venus, build reusable rocket” Russia’s Soyuz for many years made it the only country able to ferry astronauts The head of Russia’s space agency said Friday that Roscosmos wants to return to Venus and bring back soil samples and build spacecraft that will surpass Elon Musk’s rockets. Last week America’s…
“#OSIRIS-REx is one rehearsal away from touching asteroid Bennu” This artist’s concept shows the trajectory and configuration of NASA’s OSIRIS-REx spacecraft during Matchpoint rehearsal, which is the final time the mission will practice the initial steps of the sample collection sequence before touching down on asteroid Bennu.

“#NASA’s Maven observes Martian night sky pulsing in ultraviolet light” The ultraviolet “nightglow” in the Martian atmosphere. Green and white false colors represent the intensity of ultraviolet light, with white being the brightest. The nightglow was measured at about 70 kilometers (approximately 40 miles) altitude by the Imaging UltraViolet Spectrograph instrument on NASA’s MAVEN spacecraft….
“#Observatory returns from tropical storm Isaias lockdown to track asteroid for NASA” Radar range-Doppler image of 2020 NK1 reveals an elongated asteroid approximately 1 km (0.6 mi) along the longest axis. The image resolution in the vertical dimension is 100 ft (30 m) per pixel. It looks a lot like a bowling pin. Credit: Arecibo…
“#Fragments of asteroids may have jumped the gap in the early solar system” Atacama Large Millimeter Array image of the protoplanetary disk around HL Tauri. The dark rings are gaps in the dust and gas-rich protoplanetary disk, likely due to the formation of planets. These gaps may be similar to the disk gap thought to…
“#Weightless action on the space station – power, bones and bubbles” Foam-Coarsening experiment. Credit: NASA European science progressed at a slower pace on the International Space Station in the past month. As a series of spacewalks to power up the space habitat came to an end and two of its passengers left for home Earth,…
“#Decades-long deep giant cloud disruption discovered on Venus” Example of undulations behind the discontinuity on the night side on 15th April 2016. Credit: Javier Peralta/JAXA-Planet C team A planetary-scale cloud discontinuity has been periodically lashing the depths of the thick blanket of clouds on Venus for at least 35 years, says a study with the…
“#Rice researchers use InSight for deep Mars measurements” An artist’s impression of Mars’ inner structure. The topmost layer is the crust, and beneath it is the mantle, which rests on a solid inner core. Credit: NASA/JPL-Caltech Using data from NASA’s InSight Lander on Mars, Rice University seismologists have made the first direct measurements of three…
“#Lava tubes on Mars and the Moon are so wide they can host planetary bases” The morphological surface expression of lava tubes on Mars and the Moon is similar to their terrestrial counterpart. Credit: ESA / Luca Ricci The international journal Earth-Science Reviews published a paper offering an overview of lava tubes (pyroducts) on Earth,…
