Astronomers think they've detected the ripples in space and time sent out by a black hole and neutron star colliding.
The big picture: Scientists have detected gravitational waves sent out by 2 black holes merging and 2 neutron stars merging, but if confirmed, this will be the first detection of a black hole and neutron star colliding.
NASA administrator Jim Bridenstine announced Friday that the space agency's Marshall Space Flight Center in Alabama will take the lead in developing the Artemis lunar lander.
Yes, but: Lawmakers in Texas — the home of Johnson Space Center — aren't happy about it.
Uranus and Neptune — the long-neglected ice giants in the outer solar system — could be the keys to unlocking the mysteries of planets far from our solar system.
Why it matters: Scientists have found a whole bunch of planets around the size of Neptune orbiting stars light-years from our own, so learning more about our own ice giants could help us piece together exactly what's going on with those distant worlds.
