It isn't just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
Most globular clusters appear to form their stars all at once, but there are exceptions. JWST just observed how "second formations" happen.
Here on Earth, the Sun is our primary source of light, heat, and energy. But it also poses a grave threat to human civilization.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
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.
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.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
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!
For nearly a century, physicists have argued over how to interpret quantum physics. But reality exists independent of any interpretation.
Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here's the greatest one ever witnessed.
All the things that surround and compose us didn't always exist. But describing their origin depends on what 'nothing' means.
For years and over three separate experiments, "lepton universality" appeared to violate the Standard Model. LHCb at last proved otherwise.
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!
Every proton contains three quarks: two up and one down. But charm quarks, heavier than the proton itself, have been found inside. How?
Nuclear fusion has long been seen as the future of energy. As the NIF now passes the breakeven point, how close are we to our ultimate goal?
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.
