Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient "relic galaxy" in our own cosmic backyard. The very rare and odd assemblage of stars has remained essentially unchanged for the past 10 billion years. This wayward stellar island provides... Read More

Astronomers have used NASA's Hubble Space Telescope to uncover a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A. A bright, narrow, inner ring of dust is already known to encircle the star and may have been corralled by the gravitational pull of an... Read More

Imagine an object moving at super-sonic speed. This object, as it moves through a medium, causes the material in the medium to pile up, compress, and heat up. The result is a type of shock wave, known as a bow shock.

In the 1980s, scientists started discovering a new class of extremely bright sources of X-rays in galaxies. These sources were a surprise, as they were clearly located away from the supermassive black holes found in the center of galaxies. At first, researchers thought that many of these... Read More

Much like detectives study fingerprints to identify the culprit, scientists used NASA’s Hubble and Spitzer space telescopes to find the “fingerprints” of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away. And, they found a lot of water. In fact, the planet,... Read More

How would you search for signs of life – traces of tiny, living microbes or their fossilized remains – in an extreme and distant environment? NASA scientists and engineers are working on an answer to that question, aiming to find out if life ever evolved on the planet Mars and if it still harbors... Read More

This image from the Hubble Space Telescope shows the galaxy cluster PLCK G004.5-19.5. It was discovered by the ESA Planck satellite through the Sunyaev-Zel’dovich effect — the distortion of the cosmic microwave background radiation in the direction of the galaxy cluster by high-energy electrons in...

Sixty years ago, on January 31, 1958, the United States joined the "space race" with the successful launch of the Explorer 1 satellite. But the event was much more than a rocket launch.

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns — so it’s little wonder that it has earned the nickname of “El Gordo” (“the Fat One” in Spanish)!
