NASA's Great Observatories Team Up to Find Magnified and Stretched Image of Distant Galaxy

An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.

Space Telescopes Provide 3-D Journey Through Orion Nebula

Astronomers and visualization specialists from NASA's Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region.

Library of Galaxy Histories Reconstructed from Motions of Stars

Just like the Sun is moving in our galaxy, the Milky Way, all the stars in galaxies are moving, but with very different orbits: some of the stars have strong rotations, while others may be moving randomly with no clear rotation.

Hubble Frames an Explosive Galaxy

Hubble Frames an Explosive Galaxy

Don't be fooled! The cosmic swirl of stars in this NASA/ESA Hubble Space Telescope image may seem tranquil and unassuming, but this spiral galaxy, known as ESO 580-49, actually displays some explosive tendencies.

At a distance of just 160,000 light-years, the Large Magellanic Cloud is one of the Milky Way's closest companions.


Winking Star May Be Devouring Wrecked Planets

Winking Star May Be Devouring Wrecked Planets

A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets.


Astronomers Shed Light on Formation of Black Holes And Galaxies

Astronomers Shed Light on Formation of Black Holes And Galaxies

Stars forming in galaxies appear to be influenced by the supermassive black hole at the center of the galaxy, but the mechanism of how that happens has not been clear to astronomers until now.
