Such discoveries help researchers better understand the development of molecular complexity in space during star formation.
Even with just a momentary view of our galaxy right now, the data we collect enables us to reconstruct so much of our past history.
Finding it at all was a happy accident. Examining it further may help unlock the secrets hiding within the earliest galaxies of all.
“I was stunned. Here in front of me was the original apparatus through which a new vision of the world was slowly and painfully brought to light.”
Almost all of the stars, planets, and interesting physics happens in the inner portions of galaxies. Is that conventional wisdom all wrong?
A young, nearby, massive star, whose protoplanetary disk appears perfectly edge-on, was just viewed by JWST, with staggering implications.
Size matters, but it’s not the only thing.
What are dark matter and dark energy? The large-scale structure of the cosmos encodes them both, with ESA’s Euclid mission leading the way.
Air currents in our atmosphere limit the resolving power of giant telescopes, but computers and artificial stars can sharpen the blur.
Ring galaxies are rare, but we think we know how they form. A new, early-stage version, the Bullseye galaxy, provides a new testing ground.
It is a story with nebulous beginnings and no discernible end.
Dispatches host Kmele Foster is on a journey to understand humanity’s role in the cosmos. His first stop? The Atacama Plateau in Northern Chile, home to the darkest deserts and largest telescopes on earth.

Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.
It’s a radical but plausible idea.
Recent controversies bode ill for the effort to detect life on other planets by analyzing the gases in their atmospheres.
With no other galaxies in its vicinity for ~100 million light-years in all directions, it’s as isolated and lonely as a galaxy can be.
Galactic activity doesn’t just arrive when supermassive black holes feast on matter. Before, during, and after all create fascinating signs.
There are only a precious few minutes of totality during even the best solar eclipses. Don’t waste yours making these avoidable mistakes.
A recent measurement has simultaneously settled an ongoing scientific debate while puzzling scientists.
The center of the galaxy doesn’t just host stars and a black hole, but an enormous set of rich gassy and dusty features. Find out more!
Is gravity weaker over distances of billions of light-years?
Despite many ultra-distant galaxy candidates found with JWST, we still haven’t seen anything from the Universe’s first 250 million years.
Finding life beyond our Solar System requires understanding its host planet.
The Universe isn’t as “clumpy” as we think it should be.
Here in our Solar System, we only have one star: a singlet. For many systems, including the highest-mass ones, that’s anything but the norm.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
Astronomer Adam Frank reflects on some responses to his recent appearance on the Lex Fridman Podcast.
This first-of-its-kind image offers a detailed look at the magnetic fields within the Central Molecular Zone.
With infrared capabilities and image sharpness far beyond Hubble’s limits, JWST looked at Hubble’s deepest field, revealing so much more.
