I watched Armageddon again fairly recently with Bruce Willis, oil drillers in space and an asteroid the size of Texas bearing down on Earth. Buried beneath the Hollywood chaos is a genuinely interesting question: What exactly could we do with an asteroid if we got our hands on one? As it turns out, the answer has nothing to do with blowing it up,…
The Copernicus Sentinel-1D satellite, launched last November , is now fully operational after successfully completing its critical in-orbit commissioning phase. With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission – a journey that began more than a decade ago and…
When we build things on wonder, it naturally opens the mind.
The bright whites of mountain snow, muted browns of the arid plains, and gem-like blues and teals of glacial lakes typically dominate the Patagonian color palette. But for a short time in the austral autumn, temperate deciduous forests add splashes of warm tones. On April 12, 2026, a break in the clouds allowed the Landsat 9 satellite to capture…
The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it's natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers have been searching for…
We've already played a chunk of Owlcat Games' take on The Expanse, and it looks like the hard sci-fi Mass Effect successor we were hoping for.

Our sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of sun-like stars are locked in with more than one companion star. If there are two, it's known as a "binary" system, but in many cases there are even more stars all collectively tied…
Wispy nebula clouds can be seen reflecting the blue-white light of the Pleiades in the stunning amateur photo.
Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system.

From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface as solar wind. By observing this, astronomers have theorized the interaction between magnetic fields and plasma flow to be…

Being aware of the night sky even as you walk, even through a city, can give you a grounding in learning bright stars, constellations and how the night sky changes.
Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for a long time astronomers believed that the gravitational tug-of-war between two stars would make it harder for circumbinary…
