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 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...

On April 10, 2019, the international Event Horizon Telescope (EHT) collaboration revealed humanity's first glimpse of a black hole. The EHT Collaboration consists of 13 stakeholder institutes; the Academia Sinica Institute of Astronomy and Astrophysics, the University of Arizona, the University of C

A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe.

SpaceX launched the European Space Agency’s Euclid observatory toward its ultimate destination 1.5 million kilometers away, the Webb Space Telescope’s neighborhood.

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.

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.

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...

When Wylie Overstreet set up his telescope outside on a whim, he had no idea he would inspire awe in hundreds of strangers on the streets of Los Angeles, reminding them of their common humanity.

A look at the James Webb Space Telescope, its mission and the incredible technological challenge this mission presents. The Webb is now in the final stages of testing in the U.S. before being shipped to French Guiana ahead of its expected launch from there at the end of October, 2021.

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....
