Web1 dag geleden · Data from ESA’s star-mapping Gaia spacecraft has allowed astronomers to image a gigantic exoplanet using Japan's Subaru Telescope. This world is the first confirmed exoplanet found by Gaia’s ability to sense the gravitational tug or ‘wobble’ a planet induces on its star. And the technique points the way to the future of direct exoplanet imaging.

Web19 mrt. 2024 · To Newton’s contemporaries, gravity was a terrestrial force; it was restricted to objects near the Earth’s surface. What Newton discovered in the family apple orchard was that gravity is a universal force. It extends all the way out to the planets, to the Moon, to the stars, and farther.

Web15 jun. 2024 · According to Einstein, gravity is a feature of the space-time medium; the other forces of nature play out on that stage. But near the center of a black hole or in the first moments of the universe, Einstein’s equations break. Physicists need a truer picture of gravity to accurately describe these extremes. This truer theory must make the same ...
