The Hubble Space Telescope detects a protective shield defending a pair of dwarf galaxies

Scientists have used spectroscopic observations of ultraviolet light from quasars to detect and map the Magellanic Corona, a diffuse halo of hot, supercharged gas that surrounds the Small and Large Magellanic Clouds. Shown in purple, the corona extends more than 100,000 light-years from the main mass of stars, gas and dust that make up the …

NASA releases footage of ‘planetary defense test’ as spacecraft crashes into asteroid

NASA has released the first detailed images of its ground-breaking “planetary defense test” in deep space in which a spacecraft crashed into a distant asteroid in an attempt to alter its trajectory. The images were taken by what the agency calls its “big two observatories,” the James Webb and Hubble space telescopes, which captured Monday’s …

‘This one’s for the dinosaurs’: How the world reacted to NASA’s asteroid-shattering success

The crash of a spaceship is, for once, cause for celebration. Tuesday’s Dart (Double Asteroid Redirection Test) mission marked humanity’s first attempt to move an asteroid into space. Scientists from NASA and Johns Hopkins University cheered and hugged each other Tuesday after the vending machine-sized Dart successfully crashed into Dimorphos, an asteroid the size of …

Experts say the target is Venus and not Mars for the first manned mission to another planet

With a surface hot enough to melt lead, crushing atmospheric pressure and clouds of sulfuric acid, Venus might not seem like the most attractive destination for human exploration. But a group of experts argues that our other nearest neighbor, rather than Mars, should be the initial target of a manned mission to another planet. There …
