Telescope

The closest black hole to our solar system has been discovered a mere 1,000 light-years from Earth, and orbits with two companion stars that are visible to the naked eye without the aid of a telescope or binoculars.

The Hubble Space Telescope is celebrating its 30th launch anniversary with the release of a breathtakingly colorful portrait of star forming Nebulae - collectively nicknamed the "Cosmic Reef" - located in a galaxy orbiting the Milky Way.

The Spitzer Space Telescope was decommissioned on Jan. 30 this year, after more than 16 years in operation. Now NASA has released the observatory’s last-ever mosaic image, giving us a glimpse into how it works and revealing new features of a nebula.

NASA is exploring the potential of building an enormous radio telescope on the far side of the Moon in a huge impact crater. The telescope’s reflector would be comprised of a 1-km diameter wire mesh, pulled into place by wall-climbing robots.

The James Webb Space Telescope has crossed another milestone on the path to its long-awaited launch. NASA engineers have now completed a deployment test, unfurling the telescope’s gigantic mirror into the configuration it will take in space.

The first images and videos are in from the National Science Foundation's Daniel K. Inouye Solar Telescope, and they show the bubbling, explosive surface of our sun in unprecedented detail. The sheer scale, beauty and violence is breathtaking.

Scientists have discovered a massive planet evaporating as it orbits the remains of a Sun-like star. This is the first time evidence of a huge planet orbiting a white dwarf has been observed, and it could help reveal the fate of our own solar system.

Once the second-largest telescope in the world, Australia's Great Melbourne Telescope has been restored thanks to an 11-year volunteer effort after being severely damaged in a bushfire in 2003.

Scientists have captured a close-up view of the ancient alien comet 2l/Borisov, which is currently careening through our solar system before it shoots back out into interstellar space, never to be seen again.

A new view of the Milky Way has revealed how the galactic center would appear to human beings if our eyes were able to detect low-frequency radio waves.

NASA has completed a milestone test of the James Webb Space Telescope’s (JWST) sunshield, which will protect the flagship observatory from the Sun’s radiation as it unravels the secrets of the cosmos.

Back in April the world got its first direct glimpse of a black hole. Now the team behind this historic work is being awarded a Breakthrough Prize.
