Scientists have created a new version of a historic black hole image that was first unveiled back in 2019. The central black nothingness now looks larger and darker.

Astronomers are debating how quickly the observations of the Hubble Space Telescope and the James Webb Space Telescope should be made public.

Scientists using the Hubble Space Telescope have spotted light from what appears to be the most distant star ever seen. It offers a glimpse into an early moment in the history of the universe.

Building and operating telescopes can generate a lot of greenhouse gases. In fact, it's as if each astronomer in the world was driving more than 100,000 miles per year, a new study finds.

Picture perfect: Mission managers say the telescope's mirror segments have been aligned and have focused on single stars, a critical milestone, and the telescope is working flawlessly.

The James Webb Space Telescope has seen its first starlight, but its 18 mirror segments aren't yet perfectly aligned. As a result, the pictures it's sending back now aren't exactly cosmic eye candy.

The James Webb Space Telescope will give a glimpse of the earliest galaxies formed after the Big Bang — but only if the telescope is kept frigid. That's why there's a tennis court-sized sunshield.

NASA should work toward a new space telescope that could view small planets around distant stars with the potential to host life, expert panel says

Some scientists say discrimination against gay and lesbian government employees during James Webb's tenure as NASA administrator should preclude him from having a telescope named in his honor.
