Newly Found ‘Black Widow’ Binary Has Third Companion

Newly Found ‘Black Widow’ Binary Has Third Companion

The flash of a pulsar about 3,000 light-years from our solar system was caused by a ‘black widow’ binary consuming a smaller star. Intriguingly, a third companion star is orbiting the pair, which may have originated near the Milky Way’s center. Plus, the Sun is ramping up, Chandra releases more sonification videos, and this week’s What’s Up is all about occultations.

Science is the Same, Everywhere, Everywhen

Today, we bring you stories proving that we do understand some things, like black holes, and that we have forgotten other things, like that the Earth’s crust can sag under the weight of ice. It’s all a lot more complicated than we like to think. But it sure is pretty, and when the science makes your head hurt, our What’s Up segment will fill your eyes with some beauty.

Moons May Be Beneficial to Life Beyond Earth

Moons May Be Beneficial to Life Beyond Earth

New simulations find that to form a moon with a similar size ratio to our own system, certain types of planets are needed. And that type of moon-planet system could then be beneficial to the rise of life on the planet. Plus, a Starlink launch, puffy planets, and training astronauts underwater for spacewalks.
