It’s sometimes easy to forget that the light in the sky is an actual star. With how reliable it is and how busy we tend to be as humans, we can take that incredible fact and stow it away and largely ...

The University of Arizona’s Magellan Adaptive Optics Xtreme instrument, combined with a six-and-a-half meter ground-based telescope, has imaged protoplanets in sharp detail. By capturing images of the ...

Scientists develop new optical system that removes blur over fine-structure in the Sun’s corona, revealing clearest images to date This time-lapse video of a prominence above the solar surface reveals ...

For decades, scientists have struggled to see the outermost layer of the Sun, called the corona, with enough detail to unlock its secrets. This region, which blazes at millions of degrees and throws ...

It’s sometimes easy to forget that the light in the sky is an actual star. With how reliable it is and how busy we tend to be as humans, we can take that incredible fact and stow it away and largely ...

Astronomers at the Large Binocular Telescope have produced the sharpest image of a star ever seen. They used new equipment called adaptive optics to eliminate the twinkle of stars. Twinkling stars ...

A powerful new optics system has captured the clearest view yet of the Sun’s corona, revealing stunning plasma structures. Reading time 2 minutes The Sun’s outer atmosphere—the corona—is the piping ...

At the Paranal Observatory in Chile, the UT4 telescope doesn’t just observe the stars—it actively creates artificial stars to combat atmospheric interference. By shooting powerful lasers into the sky, ...

Size matters for a telescope’s image resolution. The bigger the viewing aperture, the more light it can collect. More light helps reveal fainter cosmic objects, as well as sharpen the images ...

I have been writing about the Giant Magellan Telescope for a long time. Nearly two decades ago, for example, I wrote that ...
