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 […]
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 […]
Think you can hide your feelings pretty easily?
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 […]
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.
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 […]
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 […]
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?
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, […]
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 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’ […]
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 […]
Boston Dynamics' notorious robot goes on an interplanetary mission.
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.
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 […]
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 […]
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.
Scientists should be cautious when expressing an opinion based on little more than speculation.
Quantum physics isn't quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.
Discussions of human evolution are usually backward looking, as if the greatest triumphs and challenges were in the distant past.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
Scientists used 3D scans to analyze the corpse of Amenhotep I. They discovered that his brain was never removed and that he was circumcised, among other curiosities.
The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]
To get a sense of faraway places, these 'atlases' let the locals give you their perspective.
