Supernova Fail: Giant Dying Star Collapses Straight into Black Hole

It appears the path to becoming a black hole is more complex than astronomers thought. Rather than exploding into a supernova before collapsing into a black hole, as expected, one giant star skipped the pyrotechnics and went straight to the collapse.  This so-called “massive fail,” spotted in a nearby galaxy, could explain why so few […]

Scientists have generally thought that Jupiter either harbors a relatively compact core 1 to 10 times as massive as Earth or no core at all, said Juno principal investigator Scott Bolton, who’s […]

Jupiter's Rings from the Inside! First-Ever View Captured by Juno

Humanity now has a new perspective on Jupiter’s rings, thanks to NASA’s Juno spacecraft. During its initial data-collecting dive over Jupiter’s poles on Aug. 27, 2016, Juno captured the first-ever photo of the giant planet’s faint ring system from the inside, mission team members revealed Thursday (May 25). The photo, which Juno took with its […]

'We Don't Planet' Episode 5: The Hertzsprung-Russell Diagram

If you sampled the hundreds of billions of stars in any galaxy and plotted their luminosity (their brightness measured from a fixed distance — so, in other words, their “true” brightness) and their color, you might expect the points to be essentially scattered around randomly. But the work of Ejnar Hertzsprung and Henry Russell around […]
