GPS holds the key, but astronomers can’t do it without help. Since 2019, the night sky — as seen by both human eyes and the telescopes we use to enhance our views of […]

Is the Universe the same everywhere? Or are there truly ‘special places’ around? For practically all of human history, one assumption about our place in the Universe had long gone unchallenged: […]
The Vertebrate Genomes Project may spell good news for the kakapo and the vaquita.
Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]
From high school through the professional ranks, physicists never tire of Newton’s second law.
If we succeed in contacting them, will that seal humanity’s doom? One of the most wondrous questions of all concerns our place in the Universe. After 13.8 billion years of […]
Think you can hide your feelings pretty easily?
Which is good, because if they do, they violate the cosmological principle. In theory, the Universe should be the same, on average, everywhere. A simulation of the large-scale structure of […]
The laws of physics state that you can’t create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
No matter how your year went, Hubble’s views of the Universe never disappoint. Year after year, Hubble’s telescopic views are unparalleled. Saturn, its rings, and 5 of its moons are […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
How two seemingly distinct exoplanet systems turned out to be related. Practically every star in the Milky Way has a similar origin story. At some point in the past, a molecular […]
If you thought it was just one rich region in space, look deeper and wider. Shining brilliantly in January’s skies is the Great Orion Nebula. By 10 PM every night in […]
Underperforming, the U.S. comes in only 157th out of 196 in global triangularity ranking.
The ultimate lesson from Dr. Birx is one we should never, ever repeat. About a year ago, as the world experienced the deadly “first wave” associated with the coronavirus pandemic, many […]
It’s how successful our current theories are. Some 500 years ago, there was one scientific phenomenon that was, without controversy, extremely well-understood: the motion of the celestial objects in the sky. […]
You’re gonna die, cloud! All stars, even our Sun, will someday eventually die. After burning on the main sequence for billions of years, the Sun will expand into a red giant, […]
The Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]
And if it does strike us, how much damage will it cause? Will near-Earth asteroid Apophis strike us in 2068? Generically, asteroids under ~1 km in size are irregularly shaped, will […]
The AI remembers that you are 32 years old and like to eat sushi, except on Thursdays.
Known as primordial black holes, they could thoroughly change our Universe’s history. But the evidence is strongly against them.
Boston Dynamics’ notorious robot goes on an interplanetary mission.
Yes, we’d all die. But for 21 minutes, we’d have the ride of a lifetime. One of the most remarkable facts about the Universe is this: in the absence of […]
When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]
Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]
Discussions of human evolution are usually backward looking, as if the greatest triumphs and challenges were in the distant past.
Scientists should be cautious when expressing an opinion based on little more than speculation.
Everyone is entitled to their own opinions, but no one is entitled to their own facts. Everyone is entitled to their own opinions, but no one is entitled to their own […]
Quantum physics isn’t quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.
Psychologists W. Keith Campbell, (Ph.D.) and Carolyn Crist explain why narcissists rise to power and how to make sure your support is going to someone making effective, positive change.
