The sun’s upper atmosphere, or corona, in ultraviolet light ESA & NASA/Solar Orbiter/EUI Team These fiery images are the clearest views we have ever had of the sun, taken by the Solar Orbiter spacecraft. Solar Orbiter, a joint mission between the European Space Agency (ESA) and NASA, is the most advanced instrument to orbit the […]
There is a lot to keep track of when working in space NASA via Getty Image Astronauts aboard the International Space Station (ISS) had slower memory, attention and processing speed after six months, raising concerns about the impact of cognitive impairment on future space missions to Mars. The extreme environment of space, with reduced gravity, […]
The DESI instrument observing the sky from the Nicholas U. Mayall Telescope during a meteor shower KPNO/NOIRLab/NSF/AURA/R. Sparks Albert Einstein’s theory of general relativity has been proven right on the largest scale yet. An analysis of millions of galaxies shows that the way they have evolved and clustered over billions of years is consistent with […]
General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of cosmic evolution collected by the Dark Energy Spectroscopic Instrument, or DESI. Albert Einstein’s 1915 theory, general relativity, has remained humanity’s best description of gravity for the past 100 years. Cosmologists have used general relativity to […]

Donald Trump joined Elon Musk in Texas on Tuesday to watch a successful test launch of SpaceX’s Starship rocket, a demonstration of the unprecedented closeness between the world’s richest man and the newly chosen president of the United States. Trump tweeted in advance of the launch: “I’m heading to the Great State of Texas to […]
The biggest and most powerful rocket ever built now has a half-dozen launches under its belt. SpaceX‘s 400-foot-tall (122 meters) Starship megarocket lifted off for the sixth time ever today (Nov. 19), rising off the orbital launch mount at the company’s Starbase site in South Texas at 5:00 p.m. EST (2200 GMT; 4:00 p.m. local […]
Imagine designing technology that can survive on the Moon for up to a decade, providing a continuous energy supply. NASA selected three companies to develop such systems, aimed at providing a power source at the Moon’s South Pole for Artemis missions. Three companies were awarded contracts in 2022 with plans to test their self-sustaining solar […]
SpaceX is making preparations for the sixth test flight of the world’s most powerful rocket, Starship. Elon Musk’s company has been taking a “fail fast, learn fast” approach to research and development more akin to the world of Silicon Valley than the aerospace industry, and the pace of launches only appears to be speeding up.
