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 […]

If you go young, blue, and massive, you top out at 50,000 K. That’s peanuts! Surprise! The biggest, most massive stars aren’t always the hottest. Although its neighbor, Messier 42, […]
It occurred naturally, and scientists know this for certain. Starting in late 2019, a novel strain of coronavirus, SARS-CoV-2, began infecting human beings for the very first time. Discovered in samples […]
At just 3 solar masses, it eliminates the “mass gap.” Searching for black holes is one of the most difficult astronomical games a scientist can play. Emitting no light of their […]
A volcano in California is a hot spot for conspiracy theorists.
Join Maria Konnikova live at 11am EDT tomorrow on Big Think!
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
At four million solar masses, the Milky Way's supermassive black hole is quite small for a galaxy its size. Did we lose the original?
Move over, IC 1101. You may be impressively large, but you never stood a chance against the largest known galaxy: Alcyoneus.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
And, if we have one, how close are we to it? No matter which direction we look in, or how far away our telescopes and instruments are capable of seeing, the […]
Researchers make the case for "deep evidential regression."
Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America.
If everything eventually dies and decays, is there a way to prolong the inevitable? Our Universe, as it exists today, puts us in an incredibly privileged position. Had we come […]
Yet, if they only obey the rules that we know, there’s no way to explain why. One of the greatest puzzles in all of physics is that the laws of nature — as […]
You’d have to throw out a lot of known physics for this to even be a possibility. Here’s why. It’s an undeniable scientific fact that dark matter must exist in order […]
Scientists used CT scanning and 3D-printing technology to re-create the voice of Nesyamun, an ancient Egyptian priest.
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
Researchers speculate the famous monument was one of the world’s first solar calendars, possibly inspired by trade with ancient Egyptians.
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
Did the Milky Way form by slowly accreting matter or by devouring its neighboring galaxies? At last, we're uncovering our own history.
They say that atoms are mostly 99.99999% empty space. But quantum physics says otherwise. If you were to look at what your body is made of, at smaller and more […]
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where's everyone else?
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]
Jonathan Berman wants us to have better dialogues.
And a combination of all three might take us farther than ever. If you want to see the farthest objects in the Universe, you have to know not only where to […]
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 […]
At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
The Universe is dark, but the distorted light reveals its presence. When we look at the objects in the Universe, the mass just doesn’t add up. A galaxy that was […]
