For a Decade, Astronomers Could Not Figure Out the Pink Planet. JWST Just Found Salt Clouds in Its Sky.

An exoplanet 57 light-years away has been too faint for ground-based telescopes to study since its discovery in 2013. The James Webb Space Telescope finally got a clean look and found something theorists predicted but had never confirmed: salt clouds.

For 100 Years, Scientists Could Not Explain Where Cosmic Rays Come From. Juno Just Watched Them Form.

In October 2023, NASA's Juno spacecraft crossed Jupiter's invisible bow shock and caught electrons moving near the speed of light. The discovery, published in Nature in June 2026, confirms a universal scaling law that connects particle acceleration in our solar system to the cosmic rays that stream across the galaxy.

This Four-Winged Dinosaur Glided Like a Flying Squirrel. It Hunted Early Birds.

A fossil bed in China held hundreds of ancient birds and mysterious pellets of crushed bone. The missing predator that made them has finally been discovered: a feathered, four-winged cousin of Velociraptor named Jian changmaensis.

Scientists Expected a Black Hole. They Found a Neutrino Factory Powered by Stars.

A single neutrino detected at the South Pole in 2021 led astronomers to a dust-shrouded galaxy 11 billion light-years away. The galaxy, nicknamed Shadow Blaster, had no black hole at its core. Instead, it was forming stars so intensely that the dense gas was converting cosmic rays into ghost particles.

NASA's MAVEN Spacecraft Went Silent Over Mars. It Left Behind 11 Years of Discoveries.

After more than 11 years studying how Mars lost its atmosphere, NASA's MAVEN fell silent in December 2025. In June 2026, the agency said goodbye. The mission leaves behind over 800 papers, the first measurements of atmospheric sputtering on any planet, and a direct view of what happens when the Sun strips a world bare.

JWST Just Caught an Interstellar Comet Carrying Chemicals That Don't Match Our Solar System

More than a dozen NASA missions tracked 3I/ATLAS as it passed through. Webb's MIRI instrument caught the chemical fingerprint on the way out, and found methane buried under the surface ice, the first ever detected on an object from another star system.

NASA Just Named the Crew That Will Clear the Path Back to the Moon

On June 9, 2026, NASA announced four astronauts who will fly the most complex human spaceflight mission in recent history. Their job is not to land on the Moon. It is to dock with two commercial lunar landers in Earth orbit and prove the choreography works before the next crew goes for the surface.

This Asteroid Tumbles Like a Badly Thrown Football. Scientists Just Figured Out Why.

NASA's Lucy spacecraft buzzed an asteroid called Donaldjohanson at 30,000 mph hoping to test its cameras. The data it brought back revealed a peanut-shaped rock wobbling on two axes at once, with clay minerals that still carry the chemical signature of ancient water.

Astronomers Just Found a Fragment of the Galaxy's Birth Hiding in Plain Sight

A star cluster catalogued in 1968 was filed as a globular cluster and mostly ignored. Now Webb and Hubble have shown it contains four generations of stars born across 10 billion years, making it a surviving building block from the Milky Way's formation.

A Galaxy 15 Million Light-Years Away Is Putting On a Fireworks Show Nobody Expected

Supernova remnants are supposed to fade slowly after the explosion. But when astronomers watched the galaxy M83 for 14 years with NASA's Chandra X-ray Observatory, half of them started flickering instead.

Intertwined filaments in a 540-million-year-old microfossil from the Tamengo Formation in Mato Grosso do Sul, Brazil, identified as fossilized bacterial and algal communities
Science

These 540-Million-Year-Old Fossils Were Thought to Be Animals. Then Scientists Looked Closer.

In 2017, researchers found tiny filaments in Brazilian rocks they thought were traces left by ancient worms. A new study using a particle accelerator says they were something else entirely: fossilized communities of bacteria and algae large enough to see without a microscope.

JWST Found These Little Red Dots in the Early Universe. They Were Black Hole Stars.

In 2022, JWST spotted mysterious red objects in the early universe that defied explanation. The deepest spectrum ever taken of one points to a new kind of object: a supermassive black hole wrapped in a dense cocoon of gas.
