Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where’s everyone else?

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 […]
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 […]
Lake Baikal holds nearly one-fourth of Earth’s fresh surface water and is the most scientifically interesting lake on our planet.
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 […]
Known as primordial black holes, they could thoroughly change our Universe’s history. But the evidence is strongly against them.
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 […]
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 […]
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 […]
On the largest scales, galaxies don’t simply clump together, but form superclusters. Too bad they don’t remain bound together.
After more than two decades of precision measurements, we’ve now reached the “gold standard” for how the pieces don’t fit.
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, […]
Remarkable ‘fan art’ commemorates 50th anniversary of legendary guitar player’s passing.
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 study identified superhabitable planets outside of our solar system.
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 […]
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 […]
Techshot’s 3D BioFabrication Facility successfully printed human heart tissue aboard the International Space Station.
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 […]
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 […]
The only doubts are completely unreasonable. Where did the virus that causes COVID-19, SARS-CoV-2, come from? Over the past few weeks, there’s been a tremendous push — largely among politicians but also […]
‘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 […]
An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
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 […]
Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America.
The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]
Researchers make the case for “deep evidential regression.”
With launch costs dropping and enormous numbers of new satellites filling the sky, can’t we just do it all from space?
