Featuring SpaceX’s “Mechazilla,” a first-of-its-kind spacewalk, and more.

The cofounders of think tank RethinkX are convinced that humanity is undergoing civilizational phase change.

Seven years ago, an outburst in a distant galaxy brightened and faded away. Afterward, a new supermassive black hole jet emerged, but how?

Reusable rockets, moon landers, civilian astronauts, and more.

NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.

There’s an old saying that “what you see is what you get.” When it comes to the Universe, however, there’s often more to the full story.

What are dark matter and dark energy? The large-scale structure of the cosmos encodes them both, with ESA’s Euclid mission leading the way.

Comparing Elon Musk’s Mars rocket to NASA’s new ride.

The race to find dark matter could grow more complex with high-energy neutrino interference.

NASA’s only flagship X-ray telescope ever, Chandra, still works and has no planned successor. So why does the President want to kill it?

The veteran economist joins Big Think to unpack the new rules of social media, explain tariffs, and recount his adventures in Albania.

The fabric of spacetime is four-dimensional, with three for space and only one for time. But wow, time sure is different from space!

The use of the letter x as an unknown is a relatively modern convention.

Nearly half of all stars are born in binary systems, with the most massive ones dying the fastest. It’s not pretty for the “second” star.

HaptX gloves provide high-fidelity touch feedback of virtual spaces (and they look cool, too).

NASA’s space telescopes and observatories bring humanity unrivaled science images and scientific discoveries. Here’s what should be next.

The galactic center is home to the most powerful engine in the Milky Way: a supermassive black hole. How does its energy ultimately escape?

Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.

Just 10 years ago, humanity had never directly detected a single gravitational wave. We’re closing in on 300 now, with so much more to come!

Scientists will be able to make detailed “Claymation-like” movies of chemical reactions.

Glueballs are an unusual, unconfirmed Standard Model prediction, suggesting bound states of gluons alone exist. We just found our first one.

Leadership evasion might seem like a plan for workplace freedom but it isn’t a good thing — it’s a denial of opportunity.

The COSMOS-Web survey is now complete, combining JWST and Hubble infrared data. Its spectacular views show us the Universe as never before.

Ring galaxies are rare, but we think we know how they form. A new, early-stage version, the Bullseye galaxy, provides a new testing ground.

The CMB gives us critical information about our cosmic past. But it doesn’t give us everything, and galaxy mapping can fill in a key gap.

Here in our Universe, stars shine brightly, providing light and heat to planets, moons, and more. But some objects get even hotter, by far.

An X-ray offers a glimpse into the painter’s early years.

In the earliest stages of the hot Big Bang, equal amounts of matter and antimatter should have existed. Why aren’t they equal today?

From high school through the professional ranks, physicists still take incredible lessons away from Newton’s second law.

Will we build a successor collider to the LHC? Someday, we’ll reach the true limit of what experiments can probe. But that won’t be the end.
