On Monday, scientists announced the first-ever observation of a cosmic event using both gravitational wave detectors and conventional telescopes. They witnessed a kilonova, a violent, brilliant explosion that occurs when two neutron stars collide. The discovery was a massive undertaking. Thousands o...

Launched nearly 28 years ago, the Hubble Space Telescope has changed our understanding of the cosmos, allowing us to calculate the age of the universe and the rate at which it is expanding. Hubble has allow us to peer back to almost the origins of the universe, to locations more than 13.4 billion li...

This video zooms into the core of a rich star-birth region called the Lagoon Nebula, located in the constellation Sagittarius in the direction of our Milky Way galaxy’s central bulge.

Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in fro

Astronomers are combing through fresh data from the James Webb Space Telescope in a never-ending quest to find ever-more-distant galaxies. However, the observatory is still studying a variety of objects, from insanely detailed images of Jupiter to the most distant known star.

Dr. Wendy Freedman, Chairman GMT, and Dr. Pat McCarthy, Director GMT, discuss the Giant Magellan Telescope's mirrors and the science that they will enable.

The first image from the James Webb Space Telescope was released at an event led by President Biden, Vice President Harris and NASA officials. Mr. Biden said the telescope, the most powerful ever built, "symbolizes the relentless spirit of American ingenuity." Watch the event here.

We don’t yet know what the James Webb Space Telescope will uncover. Will we get answers? Will we have more questions? One thing’s certain: The story of us is a never-ending quest for knowledge.

The Giant Magellan Telescope (GMT) is slated to be the first in a new class of extremely large telescopes, capable of producing images with 10 times the clarity of those captured by the Hubble Space Telescope. The GMT aims to discover Earth-like planets around nearby stars and the tiny distortions t...

Astronomers using the James Webb Space Telescope have discovered a galaxy that could make us revise our cosmology models. It's a galaxy named CEERS-1749, which could be the farthest galaxy to date. Astronomers have nicknamed this galaxy Schrodinger's galaxy because it could be at two places at once....
