The Universe in Infrared Light (There is no Red in Infrared) The infrared part of the electromagnetic spectrum plays an indispensable role in both terrestrial and astronomical applications. On Earth, IR light runs our remote controls, provides security and surveillance, and identifies disease. In space, infrared light allows us to explore planet surface features, quantify […]
OUR LITTLE CORNER OF THE GALAXY – THE EARTHLIGHT EXPRESS In The Earthlight Express, internationally published science artist Chris Butler brings his popular Our Little Corner of the Galaxy tours of the universe close to home – with an excursion across the wild and majestic wastelands of Earth's moon. Join Chris for a unique […]
Astro-cinematography from the Mount Laguna Observatory The stars and galaxies that fill the night sky appear roughly today as they have throughout human history. However, close inspection shows that these objects change, sometimes dramatically, over decades or months, or occasionally over just minutes. The field of time-domain astronomy has arisen in recent years thanks to […]
Music of the Spheres: Gravitational Waves from Black Holes The Nobel prize in 2016 was awarded for the detection of gravitational waves by the LIGO interferometer. So faint are these ripples that the only events powerful enough to produce detectable signals are the collisions of black holes and neutron stars, some forty times the mass […]
From Apples to Orange Juice: Can We Infer a Galaxy's Biography from Just One Photograph? Despite having data stretching back over 10 billion years and computer simulations that make realistic-looking galaxies starting from just gas and dark matter, humans do not have a theory that predicts why a galaxy looks the way it does based […]

Cosmic Dawn: The Birth of Galaxies in our Universe The Milky Way is but one of an estimated two trillion galaxies in our observable Universe. Modern astronomical telescopes have revealed a rich ecosystem of galaxies, but our Universe wasn't […]

Uncovering the Death Throes of Massive Stars Through Supernovae Stars more massive than about 10 solar masses explode at the end of their life and die as supernovae. How massive stars look like when they explode? […]
