Air currents in our atmosphere limit the resolving power of giant telescopes, but computers and artificial stars can sharpen the blur.

Einstein’s relativity overthrew the notion of absolute space and time, replacing them with a spacetime fabric. But is spacetime truly real?

The ESA’s Gaia mission just broke the record for closest black hole by over 1,000 light-years. Is there an even closer one out there?
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
It’s 50% stronger than comparable materials used in aerospace.
How scientists found out that we live in a cosmic aquarium.
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
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.
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
There’s an extra source of massive “stuff” in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe’s star-forming history firsthand.
It’s rare that one single image packs so much beauty and science simultaneously. This Hubble view of a nearby star-forming region has both.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
Your brain is trying to show you the future.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!
The midwest is particularly filled with them.
Experiments tell us quantum entanglement defies space and time.
Until the Apollo missions, we had no idea how the moon got here, just a series of educated guesses. They rewrote the story of the moon’s origins.
Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.
The laws of physics don’t prefer matter over antimatter. So how can we be certain that distant stars & galaxies aren’t made of antimatter?
NASA’s Michelle Thaller explains what happens when the densest stars in the galaxy collide.

Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.
A surprising JWST discovery around Fomalhaut has a different, superior explanation: not a great dust cloud, but a mere background object.
JWST’s revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA’s Spitzer first, it wouldn’t have been possible.
In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
Your life’s memories could, in principle, be stored in the universe’s structure.
Each December, the Geminid meteor shower puts on a show for skywatchers across Earth. With a new Moon at 2023’s peak, it’ll be outstanding!
Tracing the origin and development of jaws — and other anatomical features that humans share — sheds some light on how we came to be.
