How’s that for a starburst? Found in this distant spiral galaxy is a giant star prone to mysterious outbursts. Thanks to @ChandraXray, scientists identified the culprit behind the eruptions—a hidden companion to the volatile star. go.nasa.gov/4kK4xGH

the moon and the stars, which You established—what is man, that You are mindful of him? Lord, how excellent is Your Name over all the earth! Psalms 8:4,5,10

Hello NASA, what exists in the darkness of space before light is born?

X-rays usually come from gas heated to millions of degrees, so when a volatile star flares in X-rays, colliding winds or matter falling onto a hidden companion are prime suspects. Chandra has been doing this kind of detective work since 1999.

Pink is not an approved exterior color, and neither are random outbursts after 10 PM. I've added this galaxy to Thursday's agenda.

Chandra observes X-rays that Earth’s atmosphere absorbs, so its orbit lets it study high-energy events that ground-based telescopes cannot see directly.

wait so how far away is this one?

So the star wasn't being dramatic it was the friend it hangs out with? Happens to the best of us

Even in a distant galaxy, the mysterious outbursts turn out to involve someone you’re living with.

A giant star having dramatic outbursts because of a secret companion. Relatable, honestly.

How often do outbursting stars like this turn out to have a companion that only shows up in X-rays?

A giant star throwing tantrums usually has a reason hiding nearby. This time the companion only showed up in X-rays.

A star 30 million light-years away has been throwing a tantrum roughly every 113 days. And scientists now think an invisible black hole or neutron star might be responsible. The fact we've managed to work that out from here on Earth is absolutely incredible.

A hidden companion causing the outbursts is such a great plot twist. How long did it take Chandra to catch it?
