A photo allegedly showing the Helix Nebula and that was said to have been captured by NASA's Hubble Space Telescope was circulating online in late November 2024.

The James Webb Space Telescope has potentially smashed one of its own records again —- if scientists are correct, this trailblazing spacecraft may have glimpsed the earliest galaxies in the ...

Most galaxies fall into these basic types. However, NGC 4694 has properties of both types, complicating its classification, Hubble Space Telescope team members explained in a description of the image.

The Hubble law implies that the universe is expanding. NASA's Hubble Space Telescope, launched into low Earth orbit in 1990, has been a vital instrument for exploring the universe for over three ...

"This unique lensing configuration allows us to constrain both the Hubble constant and dark energy parameters simultaneously — something that is generally not possible." Using the James Webb ...

Thus was born the study of optics. In 1609, about a year after an unknown author made the very first attempt to patent a telescope, Galileo Galilei designed and built his famous instrument ...

In 1990, however, the Hubble telescope went into orbit 370 miles above Earth, beyond the atmospheric filter, peering perhaps 12 billion years into the past, almost to the Big Bang of 13.7 billion ...
