Hubble space telescope is being photobombed, study finds SpaceX largely to blame, as more and more images of the cosmos feature an artificial satellite in the shot By Chris Knight Published Mar 09 ...

Using the Hubble Space Telescope (HST), astronomers have observed a nearby ultra-diffuse galaxy designated F8D1. The new ...

The Hubble Space Telescope searches the universe to understand how planets, stars, and galaxies form. Recently, it captured this image of a nebula known as GN 04.32.8 within a larger stellar ...

NASA’s Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million years after the cosmic-creating Big Bang.

This new eye in the sky is a completely new instrument from its predecessor, the Hubble Space Telescope. Other than the fact that both telescopes use curved mirrors to capture the light from the ...

The image uses two different telescopes, the Hubble Space Telescope and the James Webb Space Telescope, to show the intricate details of both clusters.

For comparison, Hubble is big, about the size of a school bus — but Webb is about the size of a tennis court. Hubble's mirror, which collects light from distant objects, is 2.4 metres in diameter.

An international team of scientists recently released the largest near-infrared image ever taken by NASA’s Hubble Space Telescope, enabling astronomers to map the star-forming regions of the universe ...

The Hubble became the world’s most famous telescope, enjoyed four more repair visits and is still a workhorse, in demand by astronomers. Today we know there are at least 100 billion galaxies.
