Adams was infamously scooped when Neptune was discovered in 1846. His failure wasn’t the end, but a prelude to a world-changing discovery.

One book will gather all topics on the search for life in the Cosmos.

We know of stellar mass and supermassive black holes, but intermediate mass ones have long proved elusive. Until now.

Measurements of the acceleration of the universe don’t agree, stumping physicists working to understand the cosmic past and future. A new proposal seeks to better align these estimates — and is likely testable.

We knew we’d find galaxies unlike any seen before in its first deep-field image. But the other images hold secrets even more profound.

With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.

The James Webb Space Telescope finally could answer the age-old question of whether we are alone in the universe.

So far, gravitational waves have revealed stellar mass black holes and neutron stars, plus a cosmic background. So much more is coming.

As technology advances, the use of laser weapons in space becomes more likely.

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.

Take a peek at the pre-release images used to calibrate and commission JWST’s coldest instrument, now ready for full science operations.

When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.

We’re used to scientists telling us about the math and physics behind astronomical events. But what does studying space make us feel?

The LHC has a long, productive life ahead of it. An upgraded version, called the “High Luminosity LHC,” will be available in 2028.

One newly discovered, ancient star has a composition unlike any other. Explaining its existence is already blowing astronomers’ minds.

The brightest gamma-ray burst ever observed, GRB 221009A behaved in unexpected ways that might help us understand how they occur.

In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.

The smartest person in the world was Isaac Newton, a true polymath whose brilliance never has been, nor ever will be, surpassed.

Today, our observable Universe extends for 46 billion light-years in all directions. But early on in our history, things were much smaller.

Known as hypervelocity stars, we originally thought just one would be ejected every 100,000 years. The real number is much greater.

The upcoming launch of the James Webb Space Telescope is the event of a lifetime.

With two different black hole event horizons now directly imaged, we can see that they are, in fact, rings, not disks. But why?

Recasting the iconic Carrington Event as just one of many superstorms in Earth’s past, scientists reveal the potential for even more massive eruptions from the sun.

Due to chaos, it was long thought that planets couldn’t stably orbit systems containing three stars. GW Orionis is the first counterexample.

Theory without experiment is blind, and experiment without theory is lame.

In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?

Omer Bartov, who spent decades studying the unspeakable horrors of genocide, shares how his studies have impacted his own mental health.

Stars orbiting black holes were observed to move significantly slower than expected. One explanation centers on dark matter.

Big dreams and big telescopes are back at last, but everything depends on sufficiently funding NASA, the NSF, and the DOE.

As viewed by the MeerKAT telescope, this radio view of the Milky Way blows away every other way we’ve ever seen our home galaxy.
