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 […]

Herschel Discovers Some of the Youngest Stars Ever Seen

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 […]
