Coming from just 280 million years after the Big Bang, or 98% of cosmic history ago, this new, massive galaxy is a puzzle, but not a mirage.
If all massive objects emit Hawking radiation, not just black holes alone, then everything is unstable, even the Universe. Can that be true?
The "Doctor Strange" director says mystery shifts your worldview — "not in a metaphorical sense, but in a deeply experiential one."
There's an old saying that "what you see is what you get." When it comes to the Universe, however, there's often more to the full story.

“We don't have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”
"Nobody expects a computer simulation of a hurricane to generate real wind and real rain," writes neuroscientist Anil Seth.
Many, from neuroscientists to philosophers to anesthesiologists, have claimed to understand consciousness. Do physicists? Does anyone?
With stars, gas, and dark matter, galaxies come in a great array of sizes. This new one, Ursa Major III/UNIONS 1, is the smallest by far.
The cofounder and CEO of red-hot billing platform Metronome unpacks his leadership journey.
NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.
Just 10 years ago, humanity had never directly detected a single gravitational wave. We're closing in on 300 now, with so much more to come!
The fact that our Universe's expansion is accelerating implies that dark energy exists. But could it be even weirder than we've imagined?
The laws of physics obey certain symmetries and defy others. It's theoretically tempting to add new ones, but reality doesn't agree.
The award-winning nature writer, Robert Macfarlane, talks with Big Think about how to reacquaint ourselves with the rivers in our lives.
For centuries, vaccines have been the top life-saving, expert medical intervention known to humans. How can individuals make the right call?
Nurture your passions instead.
It took nearly 400,000 years, after the Big Bang, to first form neutral atoms. The imprints from that early time can now be seen everywhere.
The COSMOS-Web survey is now complete, combining JWST and Hubble infrared data. Its spectacular views show us the Universe as never before.
Since 1998, we've known our Universe isn't just expanding, but the expansion is accelerating. Could the Big Bang itself be the reason why?
For millennia, diamonds were the hardest known material, but they only rank at #7 on the current list. Can you guess which material is #1?
As democracy recedes and fascism rises in the USA and around the world in 2025, history provides a lesson in how science can fight fascism.
Will platforms continue to offer the like button as an all-purpose tool — or will each of the button’s various functions exist in new forms?
The laws of nature are almost perfectly symmetric between matter and antimatter, and yet our Universe is made ~100% of matter only. But why?
There are limits to where physics makes meaningful predictions: beyond the Planck length, time, or energy. Here's why we can't go further.

"It's a true fact, but a bizarre one, that the reason why hundreds of thousands of people died in Hiroshima and Nagasaki rather than Kyoto and Kokura, is because of a 19-year-old vacation and a passing cloud."
All stars shine due to an internal source of energy. Usually, it's nuclear fusion: converting mass into energy. What makes them most bright?

"There is interesting ethical questions about how we should actually conduct ourselves in [a space colonization] exploration phase."
You don't need to be a scientist or a philosopher for facts, reality, and the truth to matter. The alternative is simply known as bullshit.
In this preview from "The Saucerian," author Gabriel Mckee explains how the combination of fantastical stories and obscure bureaucracy launched the “space age of the imagination.”
