Before there were humans, planets, or even stars and galaxies, we had to make the first elements. Here’s how they happened. From the first moments of Big Bang to the […]

In honor of St. Patrick’s day and Women’s History Month, we present 10 Irish American women who changed the world in their own way.
Immediately after the Big Bang, the Universe was more energetic than ever. What was it like? When we look out at the Universe today, we see that it’s full of stars […]
For perhaps 100 million years, there were no stars in the Universe. What was it like then? The earliest stages of the Universe were extraordinarily eventful in bringing us about. Cosmic […]
They’re the fastest rotators of all. So how distorted are they? There are very few objects in the Universe that stand still; almost everything we know of rotates in some way. […]
If you can’t explain the astrophysical signal that you see and cry ‘dark matter,’ chances are you’re not thinking hard enough. Despite our knowledge of the laws of physics, and the […]
Bell Helicopter has just premiered its electric, self-piloting air taxi design at the Consumer Electronics Show (CES) in Las Vegas.
At least 60 will be running at the federal level, and thousands for state offices.
Today, our visible Universe contains 2 trillion galaxies, each with billions of stars. But when did the very first one appear? When we look out at our Universe today, there are […]
Instead of nearly-circular ellipses, comets are extraordinarily elongated, or even on an exit path. Why so different? When you look at how the planets orbit in our Solar System, the […]
What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]
As wonderful as the evidence that supports or invalidates a theory is, it can never truly kill the ones that don’t work out. When it comes to science, we like to […]
Cosmic collision yields bullion by the billions.

There’s something very special inside a proton and neutron that holds the key. There are few things in the Universe that are as easy to form, in theory, as black holes […]
Despite his famous successes, Einstein also had some failures.
There’s a halo of dark matter permeating every galaxy, and that means its particles pass through us, too. The Universe, despite all the planets, stars, gas, dust, galaxies, and more we […]
Is the world actually flat? Let’s ask someone who has some actual perspective on the subject… from space.

NASA is close to testing its next-generation nuclear fission reactors that would power a Mars colony and propel space exploration.
In 2015, Ed Witten, the greatest living string theorist, wrote a piece on why. Here’s the version for everyone. It’s one of the most brilliant, controversial and unproven ideas in […]
Out of five vital questions, which one should we most desire the answer to? Despite all we’ve learned about physics, science, and the Universe before us, there are still some incredibly […]
All the answers may lie at the center of a “regular” black hole.
Don’t believe in dark matter or dark energy? Your view of the Universe just got a lot more difficult. If you ask an astrophysicist what’s the greatest puzzle in the […]
We always assume that dark matter is particle-based, and we just need to find which particle it is. But what if it isn’t so? Everything we’ve ever detected in the Universe, […]
The first stars formed almost half a billion years before we could see their light. Here’s why. At the moment of the Big Bang, the Universe was full of matter and […]
It isn’t about saving us from aliens at all. “To be on my very first spacewalk, to be outside, and to have contamination in my suit to the point that I […]
Perhaps energy isn’t conserved at all in an expanding Universe. If you have a Universe full of stuff — whether that’s atoms, dark matter, radiation, neutrinos, or anything else — it’s virtually impossible to […]
Environmental concerns have caused some to opt-out of reproduction, both to help the planet and to protect their would-be children.
If dark energy were stronger or weaker, everything would be pretty much the same. And that’s a puzzle. After the Big Bang, the Universe was full of matter and radiation. It […]
The Dr. Data Show is a new web series that breaks the mold for data science infotainment, captivating the planet with short webisodes that cover the very best of machine learning and predictive analytics.
With a journey of 130 million light years, both signals should move at the speed of light. So why did one get here first? On August 17, after a journey taking […]
