Some black holes erase your past

You can't survive a passage into a black hole ... or can you? A UC Berkeley mathematician says you could enter certain types of black holes, but your past would be obliterated and you'd have an infinite number of possible futures.

Supermassive black hole and host galaxy not evolving together?

Astronomers assumed supermassive black holes and their host galaxies evolve together and affect each other. They call it co-evolution. But it's not happening in the distant galaxy WISE1029.

This asteroid sweeps closer than our moon today

The average distance of the moon is 239,000 miles (385,000 km). Asteroid 2018 DU will sweep significantly closer around noon, central U.S. time, today (18:22 UTC; translate UTC to your time).

Tonight and tomorrow night … Moon and Gemini
The moon's orbital motion carries it eastward through the constellations of the zodiac ... and through Gemini these next 2 nights.
