There’s a curious 200-million-year rhythm to Earth’s crust production. Now, it seems like our very place in the galaxy is tied to it.

Sagittarius A* lies in the southern sky, passing directly above South Africa.
This image shows Sagittarius A*, the black hole at the center of the Milky Way galaxy.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.

Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.

If you are a sci-fi junkie you’ve probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you’d fare all depends on the type of black hole.
Falling into a black hole is easily the worst way to die.

The scariest beast in the universe has an insatiable appetite and shreds its victims.
A black hole is an object so compact that nothing can escape its gravitational pull, not even light. They are formed when stars die and start collapsing under their own weight. Deep inside the black hole resides an infinitely hot and dense object, a so-called, singularity.

The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
