Discovery of a sulfur-bearing molecule, C₆H₅S, 27,000 light-years from Earth bridges interstellar and solar chemistry, suggesting life's building blocks formed before stars.

Astronomers have found a 13-atom chemical ring that bridges the gap between interstellar dust and the origins of life

Deep in the Milky Way, astronomers have found a 13-atom chemical ring that bridges the gap between interstellar dust and the origins of life. Until now, space sulfur was only found in tiny fragments—molecules with fewer than 6 atoms.

A fascinating exploration of the history of a famous comet reveals its connections to medieval observations, its documentation in the Bayeux Tapestry, and the scientific calculations of its orbit by astronomers in the 17th century, urging a reconsideration of its historical naming.

Edmond Halley gets the credit, but a flying monk named Eilmer knew the secret 600 years earlier.

Edmond Halley gets the credit, but a flying monk named Eilmer knew the secret 600 years earlier. "I see you, you bringer of tears..."989 AD: Eilmer, a young monk at Malmesbury Abbey, witnesses a terrifying "hairy star." It coincides with Viking raids and the death of an Archbishop. He never forgets it.

Why do icy comets contain fire-forged crystals?

Why do icy comets contain fire-forged crystals? JWST has found the answer in a violent, pulsating protostar called EC 53. The Paradox: Comets form in the freezing outer reaches of a solar system. Yet, they contain Crystalline Silicates—gems like olivine that require 1000 Kelvin heat to form.

Illustration explores the contrasting polar weather patterns of Jupiter and Saturn, detailing how the softness of interior materials influences vortex formations, with Jupiter exhibiting multiple swirling cyclones and Saturn featuring a single, vast hexagonal vortex.

Why does Saturn have one giant storm while Jupiter has a cluster of them?

Why does Saturn have one giant storm while Jupiter has a cluster of them? New fluid dynamics simulations suggest the answer lies deep underground. Jupiter and Saturn are siblings—similar size, similar gas composition. Yet their weather at the poles couldn't be more different.

Exploring the Hidden Turmoil in Galaxy Cluster Abell 3571: Despite its deceptively calm surface, multiwavelength studies reveal Abell 3571's complex past, marked by disturbances such as gas sloshing from off-axis subcluster passages. X-rays expose asymmetries and internal disruptions, shedding light on the cluster's dynamic history.

New X-ray data reveal that a massive galaxy cluster is still trembling from a cosmic collision that occurred millions of years ago.

It looks calm on the surface. But new X-ray data reveals that this massive galaxy cluster is still trembling from a cosmic collision millions of years ago. The Target: Abell 3571, a titan weighing 910 trillion solar masses. First Impression: To early X-ray telescopes, it looked "relaxed"—a perfect sphere of glowing gas. No signs of trouble.

Comparison of potential biosignatures and mimics in exoplanet exploration highlights the challenge of distinguishing true signs of life, like purple earths and green oceans, from non-biological false positives such as iron oxide and elemental sulfur.

Is Earth the only green planet? NASA's Habitable Worlds Observatory (HWO) aims to find out

Is Earth the only green planet? NASA's Habitable Worlds Observatory (HWO) aims to find out—but it might find purple worlds, green oceans, or red rocks instead.

Earth and Mercury share a cosmic melody: both planets emit similar "birdsong" electromagnetic waves, despite Mercury's weaker magnetic field. These chorus emissions, key in shaping space weather and radiation belts, advance our understanding of universal auroral processes and provide insights for future missions, including upcoming studies by BepiColombo Mio.

Scientists have detected "chirping" plasma waves at Mercury identical to those on Earth

Scientists have detected "chirping" plasma waves at Mercury identical to those on Earth, proving that even tiny magnetospheres can sing. Chorus Emissions: Electromagnetic waves generated by energetic electrons spiraling in a magnetic field. On Earth, they sound like a flock of chirping birds when converted to audio.

The timing of two exploding stars could finally tell us how fast the universe is expanding.

Two exploding stars, magnified by gravity, are arriving in replay. Their timing could finally tell us how fast the universe is expanding. Massive galaxy clusters warp space-time, acting as giant lenses. When a supernova explodes behind one, its light takes multiple paths to reach Earth.

Protostars launch powerful jets and winds, sculpting their surroundings before beginning fusion. Hubble's findings reveal these outflows don't hinder star formation, and the cavities remain unchanged as stars mature. Remarkably, our Sun once went through this dynamic protostellar phase.

Deep in the Orion Molecular Cloud, baby stars are throwing a tantrum.

Deep in the Orion Molecular Cloud, baby stars are throwing a tantrum. Powerful winds and jets are carving out caverns in the gas, shaping the future of their solar systems. A protostar isn't just a passive ball of gas. It is a violent engine. Accretion: Gas falls in from a disk, feeding the star.

This infographic explores the mysterious behavior of the red supergiant star and its newly discovered companion, Siwarha. The image explains Betelgeuse's puzzling brightness changes, the 2023 "Great Dimming," and the 6-year periodic cycle caused by Siwarha's orbit, which creates a "wake" in Betelgeuse's atmosphere.

We thought Betelgeuse was dying alone. New evidence reveals a secret partner

We thought Betelgeuse was dying alone. New evidence reveals a secret partner, "Siwarha," pushing the red giant toward its explosive fate. Betelgeuse has been acting strange—dimming, brightening, and pulsing. While some of this is due to aging, a 6-year cycle stood out.

Discovery Unveiled: JWST identifies mysterious 'little red dots' as young, supermassive black holes, weighing up to 10 million solar masses. This revelation debunks earlier theories of massive galaxies and explains the rapid growth of the universe's first black holes through ionized gas cocoons radiating red light.

These red cocoons hide the most violent engines in the cosmos

They look like faint specks in the early universe. But inside these red cocoons hide the most violent engines in the cosmos: baby black holes feeding at breakneck speeds. Since JWST launched, astronomers have been puzzled by small, red objects appearing 700 million years after the Big Bang. Were they massive galaxies?
