Japan-based Earth observation company, Synspective, launched its seventh StriX satellite into low Earth orbit, part of a multi-launch deal with Rocket Lab.
SpaceX launched its Starship megarocket for the 11th time on Monday (Oct. 13), on a successful test flight that marked the end of the road for "Version 2" of the vehicle.
Conquer the cosmos and lead ships, fleets, and even entire civilizations to victory in the best space strategy games.
NASA has announced a new wave of layoffs at its Jet Propulsion Laboratory, as the agency undergoes a sweeping "realignment" of its workforce.
The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.
Scientists say a train of CMEs could impact Earth's magnetic field Oct. 15–17, bringing a chance of northern lights across northern North America.

Modularity is taking off in more ways than one in space exploration. The design of the upcoming “Lunar Gateway” space station is supposed to be modular, with different modules being supplied by different organizations. In an effort to extend that thinking down to rovers on the ground, a new paper from researchers at Germany’s space agency (DLR), developed an architecture where a single, modular rover could be responsible for both exploration and carrying payloads around the Moon or Mars.
From glowing comets to ancient galaxies, autumn's night sky is filled with celestial treasures.
A new study finds possible references to two classic supernovae in ancient texts.
This quiz will take you on a journey through the legends, locations, and logic behind the constellations we know and love.
If you think you've met the wildest exoplanet yet, you haven't learned about TOI-4507 b. This strange world breaks almost every known rule for how planets should behave.
ESA astronaut Marco Sieber journeyed deep underground in Italy's Apennines for CAVES training
Sky & Telescope’s 2025 “Galileo’s Italy” tour offered much more than sightseeing, as participants enjoyed multiple opportunities to stand on astronomical hallowed ground.
Radio astronomy opens a window onto the invisible universe. While our eyes can detect visible light, countless objects in space emit radiation at much longer wavelengths, in the radio portion of the electromagnetic spectrum. Where visible light gets blocked by interstellar dust, radio waves pass through unrestricted revealing objects that remain completely invisible to traditional telescopes. Radio telescopes detect these waves, revealing phenomena that optical telescopes simply cannot see. Radio waves also penetrate Earth's atmosphere far more easily than many other wavelengths, making ground-based radio observatories incredibly effective tools for exploring the universe.
An interstellar comet is as its name suggests, a comet that originated outside our Solar System and travels through interstellar space before entering our neighbourhood. Unlike comets that orbit the Sun and formed within our Solar System, these rare visitors come from other star systems, traveling for millions or even billions of years across interstellar space. When they pass through our Solar System, their trajectories are hyperbolic rather than elliptical, meaning they're just passing through rather than remaining bound by the Sun's gravity. The most famous example is 2I/Borisov, discovered in 2019, which became the first confirmed interstellar comet observed.
Three new ORCS – "odd radio circles" – have been found associated with giant, active galaxies, giving astronomers clues as to how these immense, enigmatic structures form.
Rocket Lab will launch a radar satellite for the Japanese Earth-observation company Synspective today (Oct. 14), and you can watch the action live.
