“James Webb is a force to be reckoned with," Purdue professor Dan Milisavljevic said.

Today's Moment of Science is about a galaxy called UGC 1382. For a long time, scientists thought it was a fairly small, run-of-the mill galaxy, but then they realized it actually had huge spiral arms.

In 1967 a team of astronomers in Great Britain thought they had found extraterrestrial intelligence. They discovered radio sources in deep space that produced pulses of energy at very precise intervals ranging from milliseconds to seconds.

We are closer than ever to finding inhabited worlds. When an alien planet passes in front of its star, an event that's called a transit, there is a small dip in the intensity of starlight that astronomers use to detect the planet.

In 2019, scientists achieved a great goal of astrophysics when they published the first-ever image of a black hole. By coordinating radio telescopes around the world to create, in effect, one Earth-sized telescope, scientists were able to capture an image of a black hole.
