Space is massive, and in many areas, amazingly beautiful. We are fortunate to live in a time when humans are able to see at ...

1c). In the nineteenth century, the emergence of diffraction theory enabled telescope builders to understand in more detail the benefits of larger-aperture telescopes — mainly higher sensitivity ...

Scientists have developed a breakthrough coronagraph that could finally allow us to see Earth-like exoplanets hidden in the ...

In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes, is fundamentally limited by the diffraction of light.

Researchers have developed a new coronagraph—an optical device that blocks out light from a bright source—that could make it ...

The Hubble Space Telescope captured an image of a star and a spiral galaxy, both in the constellation Virgo. But the photo is an optical illusion.

A bright star within our Milky Way galaxy photobombed a beautiful new image of a distant galaxy with "patchy" spiral arms.

The stars are surrounded by diffraction spikes, which are the starburst-like radiating lines that appear around bright ...

Rings of a dying star are revealed in the nebula NGC 1514. The Webb Telescope reveals a chaotic scene long hidden from view.

NASA has released some stunning images of dying stars, offering the most in-depth view of the planetary nebula NGC 1514 to ...

NASA's James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique ...
