In 1916, Albert Einstein put the finishing touches on his Theory of General Relativity, a journey that began in 1905 with his attempts to reconcile Newton’s own theories of gravitation with the laws of electromagnetism. Once complete, Einstein’s theory provided a unified description of gravity as a geometric property of […]

Three spaceships are docked at the space station including the SpaceX Crew Dragon and Russia’s Soyuz MS-18 crew ship and ISS Progress 78 resupply ship. The new Nauka Multipurpose Logistics Module (MLM) is now attached to the Zvezda service module’s Earth-facing port. Credit: […]

An illustration of a black hole. (Image credit: Mark Garlick/Science Photo Library) The “luminous echoes” come from the rear part of the black hole’s corona Astronomers have detected light coming from behind a black hole for the first time, proving Albert Einstein right, yet again. Researchers were studying the X-rays flaring from a supermassive black hole […]

Illustration of gas-giant planet COCONUTS-2b. Credit: B. Bays (SOEST/UH) Astronomers have discovered thousands of exoplanets — planets beyond our solar system — but few have been directly imaged, because they are extremely difficult to see with existing telescopes. A University of Hawaiʻi Institute for Astronomy (IfA) graduate student has beaten […]

An image of NEID’s spectroscopic observations of the Sun. NEID’s spectral coverage extends significantly redder and bluer than the limits of human vision, enabling it to observe many critical spectral lines. NEID’s design enables high spectral resolution, large wavelength coverage, and exquisite stability. The image is inspired by the classic […]

The robotic arms of the ISS are some of its most useful tools.  The arms, designed by Canadian and Japanese space agencies, have been instrumental in ferrying around astronauts and shepherding modules to one side of the ISS.  However, the Russian segment lacked its own robotic arm – until a […]
