Even if we traveled at the speed of light, we'd never catch up to these galaxies.

Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.
There are two fundamentally different ways of measuring the Universe's expansion. They disagree. "Early dark energy" might save us.
Movie soundtracks don't just help us recall the plot of a film; they also allow us to better understand its meaning.
Nietzsche both wished he was as stupid as a cow so he wouldn’t have to contemplate existence, and pitied cows for being so stupid that they couldn’t contemplate existence.
For years and over three separate experiments, "lepton universality" appeared to violate the Standard Model. LHCb at last proved otherwise.
Whenever you're surprised, there's a good chance that your brain is busy tweaking your memories.
Space planes could radically lower the cost of spaceflight.
Hubble revolutionized astronomy more than once. Here's what we can expect from the James Webb Space Telescope.
The antibodies elicited by the "S2 vaccine" not only neutralize COVID's multiple strains but also coronaviruses that cause the common cold.
A vertical map might better represent a world dominated by China and determined by shipping routes across the iceless Arctic.
You don’t need to ride into the danger zone to take advantage of TOPGUN’s life and career lessons.
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
With advanced laser technology and an appropriate sail, we could accelerate objects to ~20% the speed of light. But would they survive?
“Hubble’s Law” is only an approximation, and breaks down when we need it most. From anywhere in the Universe, you can choose to look out at any other galaxy that’s present. […]
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.
After more than two decades of precision measurements, we've now reached the "gold standard" for how the pieces don't fit.
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?
Psychologists are finding that moral code violations can leave an enduring mark — and may require new types of therapy.
“My dad asked me if I had been to tutoring and I lied… Then he showed me the tablet."
Flexible organic circuits might someday hook right into your head.
Black holes aren't just the densest masses in the Universe, but they also spin the fastest of all massive objects. Here's why it must be so.
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
As particles travel through the Universe, there's a speed limit to how fast they're allowed to go. No, not the speed of light: below it.
The same brain differences that contribute to left-handedness also contribute to psychotic disorders. But there's a bright side.
Why, exactly, should you die for your child?
Virtual reality continues to blur the line between the physical and the digital, and it will change our lives forever.
Carl Jung was one such person.
Move over, IC 1101. You may be impressively large, but you never stood a chance against the largest known galaxy: Alcyoneus.
Here are five things to know before conducting a training evaluation.
