Solar and wind power are important, but solving the climate crisis will take a whole new generation of energy-efficient technologies, and even new companies to develop them. And there’s a growing force in the field — the green tech incubator.
Hurl your star across spacetime, hitting targets and avoiding celestial hazards in your quest to earn a star that’s big and bright enough to go supernova. As you play through the game’s 50-plus levels, you’ll meet new cosmic objects like small but dense neutron stars and massive blue supergiant stars. Get gravitational assists from these and other objects to slingshot around the galaxy and hit your targets. Detect and avoid invisible black holes that will shred your star if it gets too close. Beat all the levels and watch your star become a supernova and collapse into a black hole.

Stephon Alexander once downplayed the connections he saw between jazz and physics, concerned that — as “the only black person” in his professional circle — his credibility would be questioned. But no longer.
A hundred years ago, Einstein predicted the existence of gravity waves. Today, for the first time, scientists announced that they’ve actually been detected. Here’s what the discovery might mean for our understanding of the universe.
About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.
Minorities are historically underrepresented in science, technology, engineering and math fields. John Dimandja is a Congolese chemist on the faculty of Spelman College who’s pointing the way into STEM careers for students of color.
