Gravity as a telescope: how Einstein rings are mapping dark matter
Gravitational lensing bends light from distant galaxies around massive foreground objects, creating arcs and Einstein rings. Astronomers have turned this relativistic quirk into a precision instrument for weighing dark matter — and the results are reshaping cosmological models.

Five years of Perseverance: what the rover has actually changed about how we think about Mars
NASA's Perseverance rover has spent five years in Jezero Crater, coring ancient lake sediments and producing oxygen from thin Martian air. The science is more nuanced than the headlines suggest — and the sample cache it's building may be the most important thing it does.

Private companies are landing on the Moon. Here's what the scoreboard actually looks like.
NASA's CLPS program has funded multiple private lunar landers with mixed results. Intuitive Machines stuck the landing sideways; Astrobotic's Peregrine did not reach the surface. A clearer picture of commercial lunar capability is forming, and it's more complicated than press releases suggest.

Russia in space, 2026: what's left of the program after four years of isolation
Roscosmos has shed international partners, lost Soyuz commercial launch contracts, and watched its GLONASS constellation degrade. What remains is a human spaceflight program, a military reconnaissance constellation, and ambitious plans whose funding remains unclear.

Planetary nebulae: the most photogenic objects in the sky that no one talks about
Planetary nebulae are the glowing shells left when Sun-like stars die. The Ring, Dumbbell, and Blinking Planetary are all reachable with small telescopes. Understanding what you're looking at makes them far more interesting than any photograph suggests.

America's Astronomy Clubs: A State-by-State Guide
From Stellafane in Vermont to the Houston Astronomical Society, 203 amateur astronomy clubs span all 50 U.S. states — and what they offer goes far beyond monthly meetings under the stars.

The first private module is going to the ISS. It's a down payment on something bigger.
Axiom Space is attaching a commercial module to the International Space Station — and it's designed to eventually detach and operate as an independent station after the ISS is decommissioned. The module going up now is the foundation for the first fully private orbital outpost.

Double stars are the most underrated objects in the night sky
Point even a small telescope at the right patch of sky and you'll find pairs, triplets, and systems of stars orbiting each other in colors the naked eye can't see. Double star observing requires no dark sky, no special equipment, and no precise planning — just a list and a clear night.

Webb is finding brown dwarfs we didn't know existed. There may be as many as stars.
The James Webb Space Telescope's infrared sensitivity is revealing a population of brown dwarfs — objects too small to fuse hydrogen, too large to be planets — lurking near the Sun that previous surveys missed entirely. The implications for our census of the galaxy are significant.

China is heading to the Moon's south pole. What Chang'e 7 is actually trying to do.
China's Chang'e 7 mission is targeting the lunar south pole — the same region NASA's Artemis program is aiming for. The mission is more than a flag plant: it's the most technically complex robotic lunar mission ever attempted.

China's space station is done. Now it's being used.
Tiangong — China's modular space station — has completed its core assembly and is now hosting regular rotating crews for science, materials research, and technology demonstration. Understanding what China is actually doing in orbit matters as competition for the high ground intensifies.

The biggest 3D map of the universe ever made just got bigger. What DESI is finding.
The Dark Energy Spectroscopic Instrument has mapped tens of millions of galaxies across billions of years of cosmic history. The results are testing whether dark energy — the mysterious force accelerating the universe's expansion — behaves the way physicists assumed it did. Early hints suggest it might not.
