Scientists had a "chat" with a humpback whale. The whale's name is Twain. They spoke in "humpback language" for 20 minutes. The scientists sent a "contact call" into the ocean. Twain heard the call, swam to the boat and "chatted". A researcher said it was the first ever chat between humans and humpback whales.

Whales use contact calls so other whales know where they are. The scientists made 36 calls in 20 minutes. Twain answered them all. A scientist said her research could make it easier to talk to aliens. She said: "We can better understand what alien intelligence might be like." It will be a different kind of intelligence.
