The Most Useful Space Image Is a Graph
The prettiest image from a telescope is often the least revealing. A spectrum—a graph of light split by wavelength—is how astronomers learn what a faraway world is actually made of.

Europa Is the Best Bet for Life Beyond Earth
Beneath Europa's fractured ice sits an ocean with twice the water of Earth's seas, kept liquid for billions of years by tidal kneading. The Europa Clipper is on its way to taste it.
What If the Moon Disappeared Tomorrow?
Tides drop to 40 percent. The axial tilt wobbles between 0 and 85 degrees over millions of years. Nights go pitch black. The moon is not just a pretty rock it is the reason Earth's climate is stable enough for civilization.
Ninety Ripples: What LIGO's Third Gravitational-Wave Catalog Actually Changed
GWTC-3 added 35 new mergers to bring the total to 90, found the best neutron-star-black-hole candidates yet, and left general relativity still standing. The population statistics are where the real story is.
Ghost Streams Over Our Heads: How Gaia's Stellar Tides Map Dark Matter
Gaia has found 100+ stellar streams crisscrossing the Milky Way halo. Each gap, spur, and kink is a dark-matter subhalo's fingerprint. Here's how astronomers read them.
The Dark Energy Survey Just Mapped the Cosmic Web — Here's What the Largest Structure in the Universe Actually Looks Like
Six years, 300 million galaxies, and the most precise map of dark matter ever made. The Dark Energy Survey's final results confirm the standard cosmological model — but also hint at tensions that could point to new physics.
