JWST finds oldest black hole ever seen, and it’s hungry

Clementine observes the Moon, solar corona, and Venus in 1994. In this picture the Moon is seen illuminated solely by light reflected from the Earth — Earthshine! The bright glow on the lunar horizon is caused by light from the solar corona; the sun is just behind the lunar limb. Caught in this image is the planet Venus at the top of the frame. Credit: NASA
