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.
In the grand scheme of the cosmic story, a single year isn’t all that significant. But over time, the annual changes really add up!
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!
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.
These were the stories you clicked on the most.
Earth is actively broadcasting and actively searching for intelligent civilizations. But could our technology even detect ourselves?
All the things that surround and compose us didn’t always exist. But describing their origin depends on what ‘nothing’ means.
If aliens are driven mostly by biological imperatives, humanity could be in big trouble if we ever meet technologically advanced beings.
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.
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.
Particles are everywhere, including particles from space that stream through the human body. Here’s how they prove Einstein’s relativity.
There will always be “wolf-criers” whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
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?
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.
We thought the Big Bang started it all. Then we realized that something else came before, and it erased everything that existed prior.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.
It’s not only the gravity from galaxies in a cluster that reveal dark matter, but the ejected, intracluster stars actually trace it out.
Perhaps wormholes will no longer be relegated to the realm of science fiction.
A Carrington-magnitude event would kill millions, and cause trillions of dollars in damage. Sadly, it isn’t even the worst-case scenario.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
The answer to this question is key to understanding why anything exists.
