Space Exploration
Air currents in our atmosphere limit the resolving power of giant telescopes, but computers and artificial stars can sharpen the blur.
We are traveling in a realm that once exclusively belonged to the gods. Space travel will force humanity to rethink everything.
A conversation with an advanced alien species is likely to be simple and to take 1,000 years. It might also be dangerous.
If life is common in the Universe, then where is everybody? Known as the Fermi Paradox, a new project may help solve the riddle.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
On Earth, microbial growth is common in lava tubes no matter the location and climate, whether it’s ice-volcano interactions in Iceland or hot, sand-floored lava tubes in Saudi Arabia.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
It's a radical but plausible idea.
JWST just found its first transiting exoplanet, and it's 99% the size of Earth. But with no atmosphere seen, perhaps air is truly rare.
Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.
JWST has seen more distant galaxies than any other observatory, ever. But many candidates for "most distant of all" are likely impostors.
Most of us have heard that the Sun is an ordinary, typical, unremarkable star. But science shows we're actually anything but average.
The authors call it "wildly theoretical" — but let's take a look, anyway.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
2023 will see the launch of new rockets, the return of OSIRIS-REx, and a mission to Jupiter that could help us find extraterrestrial life.
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.
These were the stories you clicked on the most.
2022 was a year full of scientific discoveries and the dawn of the JWST. But Hubble's still going after 32 years. Here's the amazing proof!
2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.
As far as we know, it's only happened once to one unlucky person in Oklahoma.
Dead whales inspire a way to find extraterrestrial life on Mars.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
Retired astronaut Ron Garan believes that before we can begin solving our problems, we must understand our interrelatedness through the "orbital perspective."
Leaving Hubble in the dust, JWST has officially seen a galaxy from just 320 million years after the Big Bang: at just 2.3% its current age.
The very dust that blocks our view of the distant, luminous objects in the Universe is responsible for our entire existence.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
It is humanity's biggest step yet into the Solar System.
From astrobiology to geology, a Moon base could serve as a laboratory unlike anything on Earth.
