Space Science
Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won't last forever.
A Harvard astronomer went to the bottom of the ocean, claiming he recovered alien technology. But what does the science actually indicate?
Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.
In a distant galaxy, a cosmic dance between two supermassive black holes emits periodic flashes of light.
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.
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.
The outer planets' clouds hide the weirdness within.
You can't throw a DART at everything in space.
Some microbes can withstand Earth's most inhospitable corners, hinting that life may be able to survive similarly extreme conditions on other worlds.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
It's a radical but plausible idea.
The authors call it "wildly theoretical" — but let's take a look, anyway.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
In 2020, scientists took more than a kilo of moon rock and soil back to Earth for testing.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
It is humanity's biggest step yet into the Solar System.
All across the Universe, planets come in a wide variety of sizes, masses, compositions, and temperatures. And most have rain and snow.
Most exoplanets have been found around single stars via the transit method. But binary star systems might contain even more of them.
The DART mission tested whether it's possible to deflect an asteroid by crashing something into it.
As recently as 1990, we didn't know of any planets beyond our Solar System. Today, with 5000+, we're deep into the weeds of how they form.
Venus Life Finder could launch as early as 2023.
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
If you think you know how an astronomical nova works, buckle up. You're in for a ride like you never expected.
There's a whole lotta shakin' goin' on beneath the single plate of Mars.
We've only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
Europa may be difficult to access. But if a recent study is correct, its subsurface ocean would be more accessible than previously thought.
Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
