Jets may have sculpted rings of Cat’s Eye nebula
The Cat’s Eye nebula is one of the most complex of its kind. A 3-D model now reveals the source of that complexity.

Scientists can figure out a star's mass or composition pretty easily. Determining how old that star is, however, is a lot harder.
This dead star is also spinning very fast and has an amazingly powerful magnetic field.
The mysterious cosmic objects — first spotted by citizen scientists — turn out to be infant stars of various masses.
This is what scientists had suspected. But until one showed up outside our galaxy, they couldn’t be sure. Now they are.
Searching through data from NASA’s K2 Mission, researchers found a new planet. Some call it K2-315b, others smile and refer to it as “Pi Earth.”
Telescope observations of thousands of these stars now confirm a decades-old theory on how their masses relate to their waistline.
Solar Orbiter’s first images are in. The spacecraft’s pics show tiny, never-before-seen flares across the sun’s surface.
The nearest star cluster is being pulled apart, due largely to the tidal forces of our galaxy, the Milky Way. Bye bye, Hyades!
Most pinpoints that light the night sky are raging infernos we call stars. As adults, many will create new elements that they later cast off into the cosmos.
