Summary
Astronomers have confirmed the first moon-like object beyond our solar system — and immediately discovered our vocabulary cannot handle it. A Jupiter-mass world orbits a brown dwarf, which orbits a red dwarf, seventy light-years away. Is it a moon? A planet? Something we have not named yet? Also on today’s show: the Milky Way’s most powerful particle accelerator is confirmed in the direction of Altair, out-punching the Large Hadron Collider by a factor of a hundred. Chandra catches a black hole starving a galaxy it does not even live in. China flies the world’s largest solid rocket from the open ocean for the first time. Starship Flight 13 gets another window. And the Moon meets the heart of the Scorpion.
