ESO’s Very Large Telescope Interferometer has revealed the largest yellow star — and one of the ten largest stars found so far. This hypergiant has
Keck Observatory operates two ten-meter telescopes atop the summit of Mauna Kea Hawai’i. Keeping those telescopes on-sky every night is the summit crew of the
Having all four of the Unit Telescopes (UTs) working as one telescope observing the same object was a major step in the development of the
This artist’s concept illustrates a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. Gas and dust
Cutting-edge VLTI GRAVITY instrument using optical interferometry, breaks new ground in exoplanet imaging, by revealing details of a storm-wracked exoplanet.
Astronomers captured the best ever image of a star’s surface and atmosphere.
An international team of astronomers has produced the first detailed images of the surface of a giant star outside our solar system.
This is a frame from a simulation of the merger of two black holes and the resulting emission of gravitational radiation (colored fields, which represent
By linking three radio telescopes, Astronomers make the sharpest-ever observation of a distant quasar. The observation, two million times finer than human vision, via a “telescopic
