ESO is Using a New System to Allocate Telescope Time. It’s Working Well

Most astronomers know the struggle of getting time on the world’s most powerful telescopes. Even though this observing time might literally be the most important thing to their career prospects, there are always more studies than there is time available to perform them. Typically, each telescope system has a panel of experts that determine which …

A Brief History of the Discovery of Cosmic Voids

At first the sum total of large, orderly structure in the Universe appeared to arrive in two categories. There were the clusters of galaxies – an unoriginal but descriptive name – each a dense ball with anywhere from a few dozen to a few hundred galaxies, all bound together by their mutual gravitational embrace. And …

The Discovery of a Hot Neptune that Shouldn’t Exist

1800 light-years away, an unlikely survivor orbits an aged star. This rare planet is called a hot Neptune, and it’s one of only a small handful of hot Neptunes astronomers have found. Hot Neptunes are so close to their stars that the overpowering stellar radiation should’ve stripped away their atmospheres, leaving only a planetary core …

Christiaan Huygens’ Telescope Lenses Tell Us He Was Nearsighted

A world-famous 17th-century astronomer credited with discovering Saturn’s moon Titan may have needed glasses, according to a recent paper in the Royal Society Journal of the History of Science. In an era when telescope technology was less than a century old, and evolving rapidly through trial-and-error iterations, Christiaan Huygens was known for producing lenses of …
