Ever wonder what would happen if we got sucked into a black hole? Turns out we could live in it for a while — if it was big enough.

As Marcel Proust said, “The real voyage of discovery... consists not in seeking new landscapes, but in having new eyes.”
Earth-like exoplanet
Each of our three nearest stars might have an Earth-like planet in orbit around it. Here's what we'll learn when we finally observe it.

Can two planets stably share the same orbit? Conventional wisdom says no, but a look at Saturn's moons might tell a different story.
Lunar footprints.
Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won't last forever.

We may be the last generation born not knowing if we are alone in the Universe.
The concept of the warp drive is currently at odds with everything we know to be true about physics.
young exoplanetary system PDS 70
The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it's plausible.
breakthrough starshot
A Harvard astronomer went to the bottom of the ocean, claiming he recovered alien technology. But what does the science actually indicate?

Black hole jet shadow M87
Some 55 million light-years away lies the giant galaxy Messier 87. Its supermassive black hole, inside and out, looks better than ever.

For thousands of years, we puzzled at how far away the Moon was. Today we know its distance, at any time, to within millimeters.

When you turn a map of East Asia upside down, Beijing’s geographic constraints and regional ambitions become much clearer.
Saturn and Saturn's rings JWST
While Saturn and its moons all appear faint and cloudy to JWST, Saturn's rings are the star of the show. Here's the big scientific reason.

There's an entire Universe out there. So, with all that space, all those planets, and all those chances at life, why do we all live here?

In one experiment, the Viking landers added water to Martian soil samples. That might have been a very bad idea.

The truth is out there, but it's probably not in the latest whistleblower's report.
cold fuzzy dark matter simulations
In a far-reaching discovery with astrophysicist Karolina Garcia, we discuss what's in the Universe and how it grew up.

JADES deep image
Hubble showed us what our modern day Universe looks like. JWST's big goal was to teach us how the Universe grew up. Here's where we are now.
Loneliest galaxy MCG+01–02–015
With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.

Memorial day is a time to remember veterans killed in the line of service. These spaceflight heroes deserve to be remembered, too.

"Superhabitable" planets might be real, but Earth is probably as good as it gets.
