An uncrewed SpaceX Dragon capsule is on its way to the International Space Station.
Why it matters: The Dragon is carrying thousands of pounds of supplies, experiments and hardware for NASA. Those supplies include a new docking adaptor, spacesuit parts and Nickelodeon slime.
Time and time again, Einstein's theory of general relativity passes cosmic tests near and far. It's a testament to the physicist's ingenuity and scientific and technological progress. But physicists also want to see general relativity fail a test.
Driving the news: Andrea Ghez of the University of California, Los Angeles, and her colleagues report today in Science that light from a star (dubbed S0-2) passing close to the supermassive black hole at the center of the Milky Way is affected as Einstein's theory predicts.
Advent International has agreed to buy Cobham (LSE: COB), a British defense and aerospace group known for developing air-to-air refueling technology. The deal is valued at £4 billion, or 165 pence per share — 35% premium to yesterday's closing price.
Why it matters: The deal could come under severe political and regulatory scrutiny in the U.K., just as Boris Johnson takes over as prime minister. Expect particular focus on possible layoffs and broader defense manufacturing sector impact, similar to debate last year when Melrose Industries bought GKN.
