Pictured — a very scenic road to the stars. The road approaches La Silla Observatory in Chile, with the ESO’s 3.6-meter telescope just up ahead. To the left are some futuristic-looking support structures for the planned BlackGEM telescopes, an array of optical telescopes that will help locate optical counterparts to gravitational waves detections by LIGO […]

Where do stars form? One place, star forming regions known as “EGGs”, are being uncovered at the end of this giant pillar of gas and dust in the Eagle Nebula (M16). Short for evaporating gaseous globules, EGGs are dense regions of mostly molecular hydrogen gas that fragment and gravitationally collapse to form stars. Light from […]
“The flower is the poetry of reproduction. It is an example of the eternal seductiveness of life.” – Jean Giraudoux
Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however — like an approaching storm — may cause noticeable rippling in the Earth’s atmosphere. These gravity waves are oscillations in air analogous to those created when a […]

Northern winter constellations and a long arc of the Milky Way are setting in this night skyscape looking toward the Pacific Ocean from Point Reyes on planet Earth’s California coast. Sirius, alpha star of Canis Major, is prominent below the starry arc toward the left. Orion’s yellowish Betelgeuse, Aldebaran in Taurus, and the blue tinted […]
