You can now explore the cosmos to “the edge of what can be seen” in new interactive map

For the first time ever, you can time travel through space to the edge of the visible universe from the comfort of your own home. Johns Hopkins University unveiled a first-of-its-kind map on Thursday that allows users to scroll through 200,000 galaxies – "the span of the entire known cosmos."The map is a "slice of the universe" that combines more than 20 years of data to showcase information previously only seen by scientists with "pinpoint accuracy and sweeping beauty," Johns Hopkins said. In it, people can see a colorful rainbow spectrum of dots representing the actual positions and colors of 200,000 galaxies, each filled with their own billions of stars and planets. The spectrum is so vast that it dates back 13.7 billion years to a bright tie-dyed-esque line that shows an actual...

This can happen at the end of a star's life, making some black holes the result of dying stars. Scientists believe the smallest black holes came about when the universe began. There are black holes at the center of most galaxies, including our own.Because no light escapes, black hol...
