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

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 ...

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

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

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.

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

How can astronomers develop better methods for blocking the intense starlight of an exoplanetary system and reveal the ...

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

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.

This Hubble Space Telescope image of NGC 4900 appears to ... The star, which stands out due to its prominent diffraction spikes, is in our own galaxy, the Milky Way, and is 7,109 light-years ...
