In an effort to understand how black holes shape the evolution of galaxies, astronomers spent eight months creating a series of time-lapse movies from 400 observations made by NASA’s Hubble Space Telescope. The movies, taken from observations conducted over a 13-year period from 1995-2008, show a 5,000-mile-long jet [...]

Astronomers using NASA’s Hubble Space Telescope have solved a 40-year mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy.

NASA’s Hubble Space Telescope recently provided the strongest evidence yet that short-duration gamma ray bursts are produced by the merger of two small, super-dense stellar objects.

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

The planets and moons in our Solar System come in a wide variety of colors, and the natural beauty can be breathtaking. Now, the true color of a much more distant [...]

After a month-long campaign, Planetary Resources, Inc., a company with its eye on mining asteroids, reached its goal on Sunday, June 30 of raising $1.5 million through crowdfunding. The money, pledged by 17,600 supporters through the Kickstarter website, will go toward launching the world’s first public-use space telescope—Arkyd. Due to [...]
A gap in the protoplanetary disk of dust and gas whirling around TV Hydrae uncovered evidence of an unseen, growing planet, according to astronomers studying Hubble data. Image Credit: NASA, ESA, J.

It was announced this week at the 222nd meeting of American Astronomical Society that Proxima Centauri, a red dwarf and the closest star to the Sun, is predicted to pass in front of two unnamed background stars, one in [...]

New data from the Hubble Space Telescope and the Herschel Space Observatory have provided new insights into the shape and structure of the far-off Ring Nebula—whose fate has important ramifications for the future of our own Sun—and may have begun the [...]

The atmosphere is a problem for astronomers for two big reasons: it’s turbulent, so it smears out the light from cosmic objects, and it blocks out huge swathes of the electromagnetic spectrum. To see [...]
