The universe may be lopsided

The shape of the universe is not something we often think about. But my colleagues and I have published a new study suggests it could...

Earth-like planets need a cosmic-ray bath

It's quite a challenge to make an Earth-like world. You need enough mass to hold an atmosphere and generate a good magnetic field, but not...

Why astronomy needs a giant in the Canary Islands

Size matters when it comes to telescopes. The bigger they are, the farther they can see. Prioritizing constructing large ones is therefore high on...

The interstellar comet that’s spilling its secrets

When 3I/ATLAS swept past the Sun in late October 2025, it became only the third confirmed visitor from interstellar space ever detected. Unlike the mysterious...

Hot Jupiters with a memory of their past

How did hot Jupiters end up orbiting so close to their stars, thus earning their moniker? This is what a recent study published in The...

Astronomers discover giant spinning cosmic structure like a “teacup ride” in space

Astronomers have discovered one of the largest rotating structures ever seen in the universe, a vast cosmic formation that spins in a way reminiscent...

Astronomers witness ultra-fast winds erupt from a supermassive black hole

Astronomers have witnessed a dramatic and never-before-seen event near a supermassive black hole: an intense X-ray flare that, within hours, triggered ultra-fast winds blasting...

Did black holes change over time? Astronomers question a 50-year-old rule about quasars

Astronomers have uncovered surprising evidence that challenges a long-standing rule about quasars, some of the brightest objects in the universe. The discovery suggests that the...

Supermassive black holes are picky eaters during galaxy mergers, study finds

Black holes are famous for their enormous appetites, pulling in gas, dust, and even light itself. But new research shows that even the largest black...

How stardust really travels: A new study rewrites the story of life’s building blocks

The atoms that make up life on Earth—carbon, oxygen, nitrogen, and more—were forged inside stars long before our planet existed. For decades, astronomers believed they...

The solar system loses an ocean world

Saturn’s largest moon, Titan, may not have a subsurface ocean after all. That’s according to a re-examination of data captured by NASA’s Cassini spacecraft, which...

Why the same galaxy can grow or decline—It depends on its neighbor

Galaxies may look serene from afar, but their lives are shaped by powerful internal structures and by the neighbors they keep. A new study led...

Warp drives could generate gravitational waves

Will future humans use warp drives to explore the cosmos? We’re in no position to eliminate the possibility. But if our distant descendants ever do,...

How do lava worlds become earth-like, living planets

Earth was once entirely molten. Planetary scientists call this phase in a planet’s evolution a magma ocean, and Earth may have had more than one...

Ancient rocks in Mars’ Jezero crater confirm habitability

According to NASA’s Perseverance rover, ancient rocks in Jezero Crater formed in the presence of water. These sedimentary rocks are more than 3.5 billion years...

NASA’s Perseverance rover finds ‘popcorn’ rocks on Mars

NASA's Perseverance rover has discovered some strange, "popcorn"-like rocks on Mars. After months of driving, the rover has arrived at a place called "Bright...

Could halting cell death be the key to longer life—and safer space travel?

A new study suggests that stopping one particular type of cell death, known as necrosis, could dramatically change the way we treat aging, chronic...
