Read on for an entertaining (and true) story on the Soviets, the morals of society, and astronomy.
As part of our December 2015 issue’s articles on general relativity and gravitational waves, we’ve compiled some videos to help you grasp both.
The cover story of the October 2015 issue features the conundrum of massive star formation: how do these stars can form at all in the hostile environment they themselves create? Here, you'll find accompanying videos.

Thanks to NASA's New Horizons spacecraft, we're about to see Pluto up close for the first time. Here are candid snapshots of the scientists and engineers who'll make it possible.
So when astrologers talk about tides linking us to the planets, they're babbling pathetic woo.
Observers can experience Herschel’s “Night of Discovery,” featured in the April 2015 issue of Sky & Telescope, for themselves. Like the Messier Marathon, the Herschel Sprint can be completed in one moonless night in the spring. Purists can recreate the sweep using an eyepiece that provides a magnification of about 150x, sweeping in a...
S&T contributor Steve Gottlieb has made available data distilled from the Karanchentseva catalogue and his own observations to assist you in your observations of isolated triplets of galaxies.

In our March 2015 issue, we ask noted amateur and professional astronomers to highlight the astronomy apps they use most. These are apps that every astronomer should have in their back pocket, ranging from practical planetarium and weather apps, such as Scope Nights and Sky Safari 4, to science guides, such as Exoplanet and...
In the February 2015 issue of Sky & Telescope, author Marcus Woo walks readers through the science of cosmic voids. Here, videos demonstrate a sense of cosmic perspective, taking the reader on flights through the universe both theoretical and observed.
Terry N. Trees show us how to create an ephemeris, a table showing a celestial object's calculated positions for a given time period, using JPL HORIZONS data.
A full season of mutual events for Jupiter's four largest satellites As Jupiter shines brightly down from the sky during its 2014–2015 apparition, quite often Jupiter's four big Galilean moons will occult and cast their shadows on each other. A "mutual events season" like this happens about every 6 years, when Earth and Sun...
Our July 2014 cover story was the apparent discovery of gravitational waves from the instant of inflation when the Big Bang took shape. Just as the article was printed, a serious challenge to the discovery appeared: the researchers had underestimated the amount of interstellar dust that could be contaminating their data. Here are more...
