Communicate scientific ideas about the way stars, over their life cycle, produce elements.

Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.

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.

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.

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.

Close-up of the sun reveals ‘campfires’
Solar Orbiter’s first images are in. The spacecraft’s pics show tiny, never-before-seen flares across the sun’s surface.

Explainer: Stars and their families
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.

Milky Way’s tidal forces are shredding a nearby star cluster
The nearest star cluster is being pulled apart, due largely to the tidal forces of our galaxy, the Milky Way. Bye bye, Hyades!

Black hole mega-burp was truly explosive
Long, long ago, in a galaxy far, far away, a black hole blasted out 100 billion times as much energy as our sun ever will. One word for that: Wow!
