Planet Nine: the evidence is getting harder to dismiss
A cluster of trans-Neptunian objects in the outer solar system keeps orbiting in a way that looks like something massive is herding them. Surveys are now systematically searching the sky for the unseen planet — and the search has narrowed considerably.

The metal world Psyche is stranger than anyone expected
NASA's Psyche spacecraft has been orbiting the asteroid 16 Psyche — once thought to be the exposed iron core of a broken planet — and the early results are upending assumptions. The asteroid may not be what planetary scientists thought at all.

Rocket Lab is building a reusable rocket. Why Neutron is harder than it looks.
Rocket Lab has built a successful small launch business on the back of its expendable Electron rocket. Now it's attempting something far more difficult: a medium-lift reusable launch vehicle called Neutron, aimed directly at SpaceX's market.

The Sun is at its most active in two decades. What solar maximum actually means.
Solar Cycle 25 has been more active than forecasters predicted, delivering some of the strongest geomagnetic storms in years and producing aurora visible at unusually low latitudes. What solar maximum means for technology, satellites, and power grids — and how we prepare — is more relevant now than it has been in a generation.

Space tourism in 2026: who's actually going, and what it costs them
A few years after the first wave of commercial passengers reached space, the market has settled into something more defined. The flights are still rare and the prices are still very high, but the customer base has grown beyond billionaires and the competitive dynamics are shifting.

Starship made it to orbit. What that actually means for space access.
SpaceX's Starship — the largest rocket ever built — has now completed an orbital test flight with both stages recovered. The implications for what space access could cost over the next decade are difficult to overstate, and the aerospace industry is quietly reorganizing around that possibility.

ULA's Vulcan rocket is flying. What it means for the launch market.
United Launch Alliance's Vulcan Centaur has completed its certification flights and is entering regular commercial service. The rocket is designed to handle everything ULA's Atlas V and Delta IV carried — and it's arriving at a moment when the launch market is more competitive than it has ever been.

New Glenn flew. Now Blue Origin has to prove it can do it again.
Blue Origin's New Glenn rocket reached orbit on its first attempt — a significant achievement for a company that spent years being compared unfavorably to SpaceX. But a single successful launch is a beginning, not a business. What comes next will define whether New Glenn becomes a serious player.

Jupiter is at its biggest and brightest of the year. How to make the most of it.
Every thirteen months, Earth laps Jupiter in their orbits around the Sun, bringing the giant planet to opposition — closest approach, fully illuminated, visible all night. Jupiter's 2026 opposition puts it in a favorable position for northern observers, and a modest telescope will show you cloud bands, the Great Red Spot, and four moons that.

Night sky photography in 2026: what modern cameras can do that used to take an observatory
The gap between what professional astronomers can photograph and what a person with a consumer camera can photograph has collapsed in a decade. Modern sensors, computational processing, and stacking software have put Milky Way portraits and even nebula detail within reach of anyone with patience and a clear night. Here's what the technology.

A startup is building a space station. Haven-1 is closer than most people realize.
Vast Space is developing Haven-1, a small commercial space station aimed at hosting private astronauts and eventually science payloads. SpaceX is launching it. The timeline is aggressive and the company is a newcomer, but the hardware is real and the contracts are signed.

The Wow! Signal is 47 years old. We still don't know what it was.
On August 15, 1977, a radio telescope at Ohio State University detected something that fit every expected signature of a signal from extraterrestrial intelligence. It was never detected again. Decades of follow-up have generated hypotheses but no consensus. Here is where that investigation stands.
