A set of high-resolution images of the vast circumstellar debris disks around 11 nearby young stars, which were obtained with the Hubble Space Telescope, have helped astronomers to study their complex and dynamic structure for the first time in great detail. This visible-light survey, called HST/GO 12228, was done with Hubble’s Space Telescope Imaging Spectrograph (STIS), […]

Astronomers using NASA’s Hubble Space Telescope and Europe’s Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in […]

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 […]
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.

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 […]
Astronomers have found some of the youngest stars ever seen thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions. Dense envelopes of gas and dust surround the fledging stars known as protostars, making their detection difficult until now. The discovery gives scientists a window into the earliest and […]

PASADENA, Calif — A star thought to have passed the age at which it can form planets may, in fact, be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make […]
