Communicate scientific ideas about the way stars, over their life cycle, produce elements.
- Space
Scientists Say: Pulsar
These rapidly spinning dead stars send beams of radio waves into space like cosmic lighthouses.
- Physics
Scientists Say: Explosion
Explosions happen when chemical or nuclear reactions blow out a lot of heat, noise and expanding gas.
- Space
James Webb telescope catches newborn stars sculpting spiral galaxies
Dark voids riddle the galaxies, revealing new details about how stars alter their environments.
- Space
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.
- Physics
Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.
- Space
A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.

Explainer: Calculating a star’s age
Scientists can figure out a star's mass or composition pretty easily. Determining how old that star is, however, is a lot harder.
- Space
Moon-sized white dwarf is the smallest ever found
This dead star is also spinning very fast and has an amazingly powerful magnetic field.
- Space
The Milky Way’s ‘yellowballs’ are clusters of baby stars
The mysterious cosmic objects — first spotted by citizen scientists — turn out to be infant stars of various masses.
- Space
Exploding neutron star proves to be energy standout of the cosmos
This is what scientists had suspected. But until one showed up outside our galaxy, they couldn’t be sure. Now they are.
- Math
Meet ‘Pi’ — a new Earth-sized planet
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.”
- Physics
Strange but true: White dwarfs shrink as they gain mass
Telescope observations of thousands of these stars now confirm a decades-old theory on how their masses relate to their waistline.
