Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
Most globular clusters appear to form their stars all at once, but there are exceptions. JWST just observed how "second formations" happen.
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.
Though a single measurement is not enough to definitively decide the debate, this is a major win for dark matter proponents.
Yes, dark energy is real. Yes, distant galaxies recede faster and faster as time goes on. But the expansion rate isn't accelerating at all.
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.
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.
In 2020, scientists took more than a kilo of moon rock and soil back to Earth for testing.
Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here's the greatest one ever witnessed.
You can lead an overconfident chatbot to expert knowledge, but can it actually learn and assimilate new information?
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.
Dead whales inspire a way to find extraterrestrial life on Mars.
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.
The most common element in the Universe, vital for forming new stars, is hydrogen. But there's a finite amount of it; what if we run out?
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe's star-forming history firsthand.
The Universe is 13.8 billion years old, going back to the hot Big Bang. But was that truly the beginning, and is that truly its age?
We cannot afford to dream about living on other worlds while we continue to destroy ours.
