Meet Ripley, SpaceX’s Dummy Astronaut Riding on Crew Dragon Test Flight
SpaceX’s famous “Starman” dummy onboard the inaugural Falcon Heavy launch in 2018 is about to have some competition — from a new dummy, named Ripley, who will fly on the first test mission of the company’s Crew Dragon capsule.
A ‘Dragon Aurora’ Appeared in the Sky Over Iceland, and NASA Is a Little Confused
A gargantuan green dragon hisses in the sky over Iceland. Either “Game of Thrones” really upped its production budget for its final season, or the sun belched a barrage of charged particles into our atmosphere again.
‘River of Stars’ Streaming Through the Milky Way Was Hiding in Plain Sight for 1 Billion Years
One billion years ago, a cluster of stars formed in our galaxy. Since then, that cluster has whipped four long circles around the edge of the Milky Way. In that time, the Milky Way’s gravity has stretched that cluster out from a blob into a long stellar stream. Right now, the stars are passing relatively close to Earth, just about 330 light-years away. And scientists say that river of stars could help determine the mass of the entire Milky Way..
Plasma Waves Are Cooking Electrons in Earth’s Magnetic Shield
Space is warm — or, at least, warmer than it should be. All across the universe, including in our own solar system, astronomers have found that the nearly empty places between the stars and galaxies and other matter contain more heat than existing knowledge can fully explain.
This Supercomputer Can Calculate in 1 Second What Would Take You 6 Billion Years
A physics laboratory in Tennessee just unveiled Summit, likely to be named the world’s speediest and smartest supercomputer.
The Higgs Boson Has a New Friend
The Higgs boson appeared again at the world’s largest atom smasher — this time, alongside a top quark and an antitop quark, the heaviest known fundamental particles. And this new discovery could help scientists better understand why fundamental particles have the mass they do.
Building Sails for Tiny Interstellar Probes Will Be Tough — But Not Impossible
Giant lasers may indeed launch fleets of spacecraft to Alpha Centauri, given breakthroughs in the science behind extraordinarily thin, incredibly reflective sails that can catch this laser light, a new study finds.
Aerodynamic Astronomy: Extremely Large Telescope Tackles Wind Tunnel
Engineers with the European Southern Observatory (ESO) are conducting wind-tunnel tests for the astronomical organization’s Extremely Large Telescope (ELT), a massive new telescope scheduled to begin scanning the cosmos in 2024. But why would you need wind-tunnel tests for a telescope? There’s a simple answer: size.
