Signals buried deep in gravitational wave observatories’ data point to a collision of two black holes that were clearly born in different places. Almost all of the spacetime ripples observed by experiments such as the Laser Interferometer Gravitational-Wave Observatory, or … Read More
Our observable Universe is the region of space that we can see today — all points in space where light has had enough time to reach us if it left at the Big Bang (13.7 billion years ago) or later. … Read More
The Andromeda Galaxy is a giant swirl of around a trillion stars just down the street from the Milky Way. But billions of years from now, it will collide with our home galaxy. On a clear night away from city … Read More

Monsters lurk in the cores of all galaxies: supermassive black holes millions or billions of times the mass of our Sun. And as galaxies merge, so, too, do these black holes, which gradually approach each other over millions of years. … Read More
Imaged by the Gemini Observatory in Hawaii, the galaxies NGC 5394 (the smaller one, on the right) and NGC 5395 (the larger one, on the left) are in the middle of colliding over the span of millions of years. It … Read More
