If you’ve spent some time stargazing, you know what a calm, peaceful place our universe can be. But did you know that a monster is hiding right in the heart of our Milky Way galaxy? Astronomers noticed stars zipping superfast around something we can’t see at the center of the galaxy, about 10 million miles per hour! The stars must be circling a supermassive black hole. No other object would have strong enough gravity to keep them from flying off into space.

Two astrophysicists won half of the Nobel Prize in Physics last year for revealing this dark secret. The black hole is truly monstrous, weighing about four million times as much as our Sun! And it seems our home galaxy is no exception – our Hubble Space Telescope has revealed that the hubs of most galaxies contain supermassive black holes.
 
HONG KONG (AP) — Sophia is a robot of many talents — she speaks, jokes, sings and even makes art. In March, she caused a stir in the art world when a digital work she created as part of a collaboration was sold at an auction for $688,888 in the form of a non-fungible token (NFT)...........

Sophia will carry on painting, Hanson said, and the next step in the robot’s career could be that of a musician. She is working on several musical works in a project called Sophia Pop, where she collaborates with human musicians to generate music and lyrics, he said.

“We’re so excited about Sophia’s career as an artist,” Hanson said.................

Some 100,000 years ago, an extended family of 36 Neanderthals walked along a beach, with the kids jumping and frolicking in the sand, scientists report after analyzing the beachgoers' fossilized footprints in what is now southern Spain.

"We have found some areas where several small footprints appeared grouped in a chaotic arrangement," said Eduardo Mayoral, a paleontologist at the University of Huelva and lead author of the study, which was published online March 11 in the journal Scientific Reports.

The footprints "could indicate an area of passage of very young individuals, as if they were playing or loitering on the shore of the nearby waterlogged area," Mayoral told Live Science in an email...............

One Tyrannosaurus rex seems scary enough. Now picture 2.5 billion of them. That’s how many of the fierce dinosaur king probably roamed Earth over the course of a couple million years, a new study finds.

Using calculations based on body size, sexual maturity and the creatures’ energy needs, a team at the University of California, Berkeley figured out just how many T. rexlived over 127,000 generations, according to a study in Thursday’s journal Science. It’s a first-of-its-kind number, but just an estimate with a margin of error that is the size of a T. rex.........

 
SAN RAMON, Calif. (AP) — The Google Earth app is adding a new video feature that draws upon nearly four decades of satellite imagery to vividly illustrate how climate change has affected glaciers, beaches, forests and other places around the world.

The tool unveiled Thursday is rolling out in what is being billed as the biggest update to Google Earth in five years. Google says it undertook the complex project in partnership with several government agencies, including NASA in the U.S. and its European counterpart, in hopes that it will help a mass audience grasp the sometimes abstract concept of climate change in more tangible terms through its free Earth app.


Cornell University climate scientist Natalie Mahowald believes that mission may be accomplished.

“This is amazing,” she told The Associated Press after watching a preview of the new feature. “Trying to get people to understand the scope of the climate change and the land use problem is so difficult because of the long time and spatial scales. I would not be surprised if this one bit of software changes many people’s minds about the scale of the impact of humans on the environment.”........
