Here are the best lunar events to see in 2026, including eclipses, supermoons and conjunctions.
This lightweight medium-format powerhouse is one of the most powerful cameras you can get, but how does it work for astrophotography?
Beneath the Moon’s cratered surface lie networks of lava tubes and deep pits, natural caves that could shelter future lunar bases from cosmic radiation and wild temperature swings. These underground structures represent some of the most scientifically valuable areas in the Solar System, but they come with the very real challenge of simply getting there!
A thousand light years from Earth, something enormous is happening. The Hubble Space Telescope has captured images of the largest protoplanetary disk ever observed, a swirling mass of gas and dust that spans nearly 640 billion km. To put that in perspective, it’s 40 times wider than our entire Solar System, from the Sun to the outer edge of the Kuiper Belt where comets drift in the darkness.

This low-cost mission is still only getting started, and it's taking bigger risks than typical big-ticket NASA missions.
At the end of their lives, most satellites fall to their death. Many of the smaller ones, including most of those going up as part of the “mega-constellations” currently under construction, are intended to burn up in the atmosphere. This Design for Demise (D4D) principle has unintended consequences, according to a paper by Antoinette Ott and Christophe Bonnal, both of whom work for MaiaSpace, a company designing reusable launch vehicles for the small satellite market.

Here are eight of the most spectacular astronomical discoveries of 2025.
The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx), which launched back in May, was designed to explore the cosmos in optical and near-infrared light. Over its planned two-year mission, this observatory will observe the entire sky using a triple-mirror telescope and mercury-cadmium-telluride photodetector arrays, allowing it to gather data on more than 450 million galaxies, including the 100 million stars in the Milky Way, to explore the origins of the Universe.

Solar sails have some major advantages over traditional propulsion methods - most notably they don’t use any propellant. But, how exactly do they turn? In traditional sailing, a ship’s captain can simply adjust the angle of the sail itself to catch the wind at a different angle. But they also have the added advantage of a rudder, which doesn’t work when sailing on light. This has been a long-standing challenge, but a new paper available in pre-print from arXiv, by Gulzhan Aldan and Igor Bargatin at the University of Pennsylvania describes a new technique to turn solar sails - kirigami.
It's the 12 days of Spacemas, fa la la la la la la la la (sorry).
