Super-dense Star is First Ever Found Suddenly Slowing Its Spin
A neutron star is the densest object astronomers can observe directly, crushing half a million times Earth's mass into a sphere about 12 miles across -- roughly the size of Pittsburgh, or the distance between the Penn State University Park Campus and Bellefonte, Pennsylvania, as shown in this illustration.

White-Dwarf Star, Blown Apart in 1604, Now Reveals New Secrets
This composite of images from NASA's Chandra X-ray Observatory shows the remnant of Kepler's supernova in low-energy (red), intermediate-energy (green) and high-energy (blue) X-rays. Credit: X-ray: NASA/CXC/NCSU/M.Burkey et al.; optical: DSS
Remnants of a Shattered Star Discovered in Milky Way
This composite image of supernova remnant G306.3-0.9 merges Chandra X-ray observations (blue), infrared data acquired by the Spitzer Space Telescope (red and cyan) and radio observations (purple) from the Australia Telescope Compact Array. The image is 20 arcminutes across, which corresponds to 150 light-years at the remnant's estimated distance. Credit: X-ray: NASA/CXC/Univ. of Michigan/M.

The Closest Star System Found in a Century
WISE J104915.57-531906 was discovered through its rapid motion across the sky, which is shown in these images taken between 1978 and 2010 by the Digitized Sky Survey, the Two Micron All-Sky Survey, and the WISE satellite. Credit: NASA/STScI/JPL/IPAC/University of Massachusetts
Oldest Known Star Gets a Birthdate Update
This image is an illustration of the oldest star ever found in our solar neighborhood. The aging star, cataloged as HD 140283, lies 190.1 light-years from Earth. Credit: NASA, ESA, and A. Feild and F. Summers (STScI)
