Black Hole
Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here's the greatest one ever witnessed.
2022 was a year full of scientific discoveries and the dawn of the JWST. But Hubble's still going after 32 years. Here's the amazing proof!
Perhaps wormholes will no longer be relegated to the realm of science fiction.
We'll never be able to extract any information about what's inside a black hole's event horizon. Here's why a singularity is inevitable.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
Supermassive black holes at the centers of galaxies gobble up whatever matter ventures too close, becoming active. Here's how they work.
The ESA's Gaia mission just broke the record for closest black hole by over 1,000 light-years. Is there an even closer one out there?
In 1974, Stephen Hawking showed that even black holes don't live forever, but emit radiation and eventually evaporate. Here's how.
1.9 billion years ago, a star's explosive death created a black hole. Its light just arrived at Earth. But did it set a cosmic record?
Black holes aren't just the densest masses in the Universe, but they also spin the fastest of all massive objects. Here's why it must be so.
The first set of James Webb's images blew us all away. In just 2 mere months, it's seen highlights that no one could have predicted.
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
We only detected our very first gravitational wave in 2015. Over the next two decades, we'll have thousands more.
Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?
It started with a bang, but won't end with one. Instead, it will "rage against the dying of the light" like nothing you've ever imagined.
LIGO can detect the inspirals and mergers of the lowest-mass black holes, but not the biggest ones. Here's how pulsars can help.
At all distances, the Universe expands along our line-of-sight. But we can't measure side-to-side motions; could it be rotating as well?
With two different black hole event horizons now directly imaged, we can see that they are, in fact, rings, not disks. But why?
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
The James Webb Space Telescope is about to begin science operations. Here's what astronomers are excited about.
On July 12, 2022, JWST will release its first science images. Here are 5 ways the telescope's findings could change science forever.
According to renowned physicist Christophe Galfard, physics can’t explain our universe - yet.

Everything is made of matter, not antimatter, including black holes. If antimatter black holes existed, what would they do?
At four million solar masses, the Milky Way's supermassive black hole is quite small for a galaxy its size. Did we lose the original?
The idea of black holes has been around for over 200 years. Today, we're seeing them in previously unimaginable ways.
Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.
After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way's central black hole looks like.
Everything that gets heated up has to, somehow, radiate that energy away. Here's what we see when that happens in the Universe.
