This deep view of the Orion Constellation glows in reddish hues thanks to a filtered view of hydrogen alpha emission, a type ...

From a Mars rover selfie to an astronaut's view of the flower moon, these space images will give you a new perspective on our ...

Astronomers Just Found It. Hydrogen in space can glow, as is the case with the Orion Nebula, but has insufficient density and irradiation to achieve brightness in intergalactic space.

Scientists didn't expect that stars would be able to still form in the dwarf galaxy known as Leo P, which the James Webb Telescope recently imaged.

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy—the earliest cosmic time yet accessible to humans. Measuring ...

There’s a lot of information in the vibrant colors of the newest images from NASA’s James Webb Space Telescope. Behind the scenes, a lot of aesthetic decisions go into polishing space images ...

The images show what appears to be clouds, but is in fact regions with less dense hydrogen and helium—over billions of years, gravity would pull the denser regions inwards, to begin building ...

Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

What do you get when you put a one-meter parabolic dish, an SDR, a Raspberry Pi, and an H1-LNA for 21 cm emissions together? The answer is: a radio telescope that can track hydrogen in the Milky Wa… ...

With a new image, NASA commemorates the first anniversary of doing science with the most powerful observatory ever sent to space.

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.
