By transforming idle heliostats into asteroid detectors, scientists aim to develop a cost-effective method for spotting faint, fast-moving space rocks.

You can save 20% on the Hommkiety Galaxy Projector on Amazon, which we praised for its build quality and high-end projections.

When rocks fracture in underground faults, they generate a variety of chemical compounds that could provide more energy sources for microbes in Earth’s depths

Sky & Telescope Associate Editor Sean Walker and Contributing Editor Stephen James O’Meara accompanied nine adventurers on a stargazing safari for an immersive experience in the African bush in Botswana.

The post Southern Splendors on Safari appeared first on Sky & Telescope.

The image reveals over 2,500 galaxies, many of which are seen as they were during the first billion years of cosmic history.

Our Sun frequently erupts in loops.

Is the Helix Nebula looking at you?

What are these gigantic blue arcs near the Andromeda Galaxy (M31)?

A brutal alien planet isn't quite the same as future Earth, but Predator: Concrete Jungle has more than a few things in common with Predator: Badlands.

Birds are starting to make their way south for the winter, and you’ve got a front-row seat to the show

NASA is calling on the public to help shape the future of lunar exploration by designing the next generation of wheels capable of navigating the moon's harsh terrain.

Imagine 3D printing an entire building from Moon dust, or having robots construct disaster relief shelters while humans stay safely away from danger. Imagine construction sites where materials never run out because they're literally made from the dirt beneath your feet, and where every structure is built with manufacturing level precision. What sounds like science fiction is becoming reality as engineers solve the ultimate construction puzzle, building on other planets. The innovations being pioneered for lunar bases and Martian colonies are about to transform every construction site on our home planet.

Scientists are exploring various proposals to repurpose existing spacecraft in order to chase after the interstellar object 3I/ATLAS and take a closer look – but time is against them
