Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. This map will enable 3D distance measurements to other galaxies

Solar sails have some major advantages over traditional propulsion methods – most notably they don’t use any propellant. But, how exactly do they turn? In traditional sailing, a ship’s captain

Even most rocket scientists would rather avoid hard math when they don’t have to do it. So when it comes to figuring out orbits in complex three-body systems, like those

One of the primary goals of the James Webb Space Telescope (JWST) is to detect atmospheres around exoplanets, to try to suss out whether or not they could potentially support

During November 2025, ESA’s Jupiter Icy Moons Explorer (JUICE) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what
