Humanity’s newest, most powerful space telescope is performing even better than predicted. The reason why is unprecedented.
There are two methods to measure the expansion rate of the Universe. The results do not agree with each other, and this is a big problem.
Galactic activity doesn’t just arrive when supermassive black holes feast on matter. Before, during, and after all create fascinating signs.
Today, the Large Hadron Collider is the most powerful particle physics experiment in history. What would a new, successor collider teach us?
Sure, there’s less daylight during winter than summer, as your hemisphere is tilted away from the Sun. But darkness goes deeper than that.
Lasers are all around you. This ubiquitous technology came from our understanding of quantum physics.
If you look into a mirror, you’ll notice that left-and-right are reversed, but up-and-down is preserved. The reason isn’t what you think.
Gravitational waves carry enormous amounts of energy, but spread out quickly once they leave the source. Could they ever create black holes?
A deep dive into the chaotic journey of star formation.
In the infant Universe, particle physics reigned supreme.
Do we actually live in a deterministic Universe, despite quantum physics? An alternative, non-spooky interpretation has now been ruled out.
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.
The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?
In the very early Universe, practically all particles were massless. Then the Higgs symmetry broke, and suddenly everything was different.
On Saturday, October 14, a solar eclipse crosses North and South America. Here are 4 quick, easy, low-tech activities for everyone to enjoy!
For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.

From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
Finding it at all was a happy accident. Examining it further may help unlock the secrets hiding within the earliest galaxies of all.
Temperatures in the Sun’s core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?
Misinformation was extremely popular in 2023, as bad science often made global headlines. Learn the truth behind these 10 dubious stories.
The last naked-eye Milky Way supernova happened way back in 1604. The next one could be the key to solving the dark matter mystery.
With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
Michael Faraday’s 1834 law of induction was the key experiment behind the eventual discovery of relativity. Einstein admitted it himself.
In a recent paper, biologists outlined a three-part hypothesis for how all life as we know it began.
We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.
JWST has already broken many of Hubble’s cosmic records. Perhaps additional record-breakers already exist within this data-rich image?
