Scientists are trying to solve the mystery of why a narwhal was adopted by a group of beluga whales in Canada’s St. Lawrence River.
Killer whales share some personality traits with humans and chimps – such as playfulness, independence, stubbornness, bravery, sensitivity and protectiveness – according to a new study.

Researchers have identified a large meteorite impact crater hiding under the Greenland ice. The enormous crater – bigger than Paris – appears to be result of meteor strike just 12,000 years ago.
The giant iceberg – about 3 times the size of Manhattan – broke off from Pine Island Glacier in late October. Scientists say the frequency of such events appears to be on the rise.

Gaia satellite data revealed the galaxy, which has avoided detection until now, thanks to its extremely low density and hiding place behind the shroud of the Milky Way’s disk.

Activity on the sun’s surface creates the conditions known as space weather, that can, at its worst, damage Earth satellites and cause electrical blackouts.

Late last month, a team of researchers said Earth’s oceans had warmed 60% more than anyone had realized. Now that result appears unlikely, since a mathematician and climate contrarian has uncovered a scientific error.

Astronomers are “99 percent confident” that this exoplanet is real and not a false detection. The planet for Barnard’s star – 2nd closest star system to our sun – appears to be a cold super-Earth.
Barnard's star - the 2nd closest star to Earth - has a large proper motion on our sky's dome. This image - via One-Minute Astronomer https://oneminuteastronomer.com/8869/barnards-star/ - shows its motion from 1991 to 2007.
Sometimes called Barnard’s Runaway Star, it’s one of the best known stars in the history of astronomy and in popular culture.
