New episode "Lux" reveals that characters talking directly to the audience was just the start.

NASA astronaut Don Pettit and two cosmonaut colleagues will return to Earth from the International Space Station this evening (April 19), and you can watch it live.

Using NASA's Perseverance rover to analyze Martian rocks, researchers suggest that Mars' complex volcanism might hold clues about the planet's ancient habitability.

Landing off the coast of the Bahamas offers SpaceX new rocket flight trajectories.

Russia's Alexey Ovchinin handed the keys of the International Space Station to Japanese spaceflyer Takuya Onishi in a change-of-command ceremony today (April 18).

NASA's PUNCH sun-studying mission has seen first light — and the team says all four instruments are indeed working as expected.

The Mandalorian's next chapter will blast into theaters in 2026, and we're learning more about its characters and story.

Most people know weed gets you high—but do you know how THC actually does it?

This towering structure of billowing gas and dark, obscuring dust might only be a small portion of the Eagle Nebula, but it is no less majestic in appearance for it. 9.5 light-years tall and 7000 light-years distant from Earth, this dusty sculpture is refreshed with the use of new processing techniques.

This newly reprocessed image released on April 18, 2025, provides a new view of an enormous, 9.5-light-year-tall pillar of cold gas and dust. Despite its size, it’s just one small piece of the greater Eagle Nebula, also called Messier 16.

The Eagle Nebula is one of many nebulae in the Milky Way that are known for their sculpted, dusty clouds. Nebulae take on these fantastic shapes when exposed to powerful radiation and winds from infant stars. Regions with denser gas are more able to withstand the onslaught of radiation and stellar winds from young stars, and these dense areas remain as dusty sculptures like the starry pillar shown here.

According to a recent study by the non-profit Explore Titan, a nuclear-fission propulsion spacecraft could enable the first crewed mission to Titan, Saturn's largest moon.

In our neighborhood of the Milky Way, we see a region surrounding the solar system that is far less dense than average. But that space, that cavity, is a very irregular, elongated shape. What little material is left inside of this cavity is insanely hot, as it has a temperature of around a million Kelvin.

Researchers discover a new color outside the range of human color vision, but you have to laser your retinas to see it

These solar binoculars offer lots of magnification for observing sunspots and solar eclipses, but their big size makes them a specialist purchase.

Astronomers have stumbled upon yet another ghostly galaxy that appears to be devoid of dark matter, the elusive stuff that makes up most of the material universe.
