The highest-energy particles of all come from space, not human-made colliders. When it comes to the most energetic particle collisions of all, you might think that the Large Hadron Collider […]
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
We have pipelines for oil and natural gas. Why not water?
If it weren’t for a subatomic quantum rule, our Universe would be vastly different. In many ways, our views of the distant Universe are the closest things we’ll ever get […]
When three wise men gifted baby Jesus with gold, frankincense, and myrrh, they had no idea one was made from colliding neutron stars.
Often viewed as a theoretical, calculational tool only, the Lamb Shift proved their existence. If you spend enough time listening to theoretical physicists, it starts to sound like there are […]
NASA astronomer Michelle Thaller is coming back to Big Think’s studio soon to answer YOUR questions! Here’s all you need to know to submit your science-related inquiries.
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?
In 1990, we only knew of the ones in our Solar System. Today, we know of thousands, and that’s just the tip of the iceberg.
A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
Move over, IC 1101. You may be impressively large, but you never stood a chance against the largest known galaxy: Alcyoneus.
Researchers speculate the famous monument was one of the world’s first solar calendars, possibly inspired by trade with ancient Egyptians.
Scientists discover burrows of giant predator worms that lived on the seafloor 20 million years ago.
All the latest titles from the experts at MIT.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
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, […]
Did the Milky Way form by slowly accreting matter or by devouring its neighboring galaxies? At last, we’re uncovering our own history.
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 […]
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where’s everyone else?
Physics demands that it couldn’t be any other way. Here’s why. Ask anyone — even someone with no background in science — to name something that Einstein did, and odds are they’ll come back with […]
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 […]
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 […]
In recent years, women have made incredible strides in the business world. Forty-one women currently lead Fortune 500 companies. While that remains an unacceptably low percentage (8 percent) overall, it […]
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 […]
Lake Baikal holds nearly one-fourth of Earth’s fresh surface water and is the most scientifically interesting lake on our planet.
Known as primordial black holes, they could thoroughly change our Universe’s history. But the evidence is strongly against them.
Remarkable ‘fan art’ commemorates 50th anniversary of legendary guitar player’s passing.
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 […]
