Host Michelle Thaller talks with Bad Astronomy's Phil Plait about a conundrum: why are humans so quick to explain the unknowns of the cosmos as aliens? And why is this healthy imagination important in science?
Astronomer Annie Jump Cannon (1863-1941) classified hundreds of thousands of stars and created the system we use to understand stars today.
You can't get rid of noise in your astrophotographs, but you can reduce its impact with more signal.
Courtesy of The Kavli Foundation, read the conversation between two 2016 Kavli Prize laureates as they discuss the struggle to detect gravitational waves and how their discovery is changing our understanding of the universe.
El 21 de Agosto del 2017 va a ser la primera vez que los Americanos podrán ver un eclipse total de Sol desde 1949. Un espectáculo tan grandioso obtendrá mucha atención, pero también atrae mucha planificación necesaria.
African American physicist, Arthur B.C. Walker Jr. (1936-2001), helped develop solar telescopes to image the Sun’s corona.
American astronomer Vera Rubin (1928 - ) measured how fast galaxies rotate, delivering decisive evidence for the existence of dark matter.
Learn how to photograph a meteor shower with these step-by-step instructions, as well as advice for the advanced imager.
The phases of the Moon are determined by the relative positions of the Moon, Earth, and Sun.
Few amateurs have looked through a telescope and not imagined what it would be like to take a photo of the target in the eyepiece. I know I did when I got my first telescope. But back then, astrophotography was practically a black art: 35mm film was the only medium of choice, and it required…
The Kavli Foundation hosted a Q&A with three astronomers to probe the recent discovery of hard-to-produce heavy elements in a nearby dwarf galaxy. The discovery sheds light on stellar histories and galactic evolution.
Prepare for the 2017 solar eclipse with these basic facts and other resources.
It's easy to take high-quality images of the lunar disk.
Learn how powerful new telescopes and techniques are enabling scientists to probe planets in the earliest stages of development.
To mark the start of a new era of astronomy, three principal LIGO researchers speak with The Kavli Foundation on their epic discovery and how it will transform the way we see the cosmos.
Crowd-sourcing the universe: Thanks to online portals, legions of volunteer astronomers are turning their eyes to the sky and doing extraordinary science. Three scientists discuss the future of citizen astronomy.
Our Constellation Basics webinar provides background information about the major winter constellations. Here are some accompanying online resources.
Asterisms appeal to our playful side but also serve as key waypoints in the sky for identifying fainter stars and constellations.
A newfound alien world orbiting a small, nearby star could be one of the first exoplanets scientists get to investigate in detail. Three astrophysicists discuss the possibilities.
Sky & Telescope is starting a series of webinars with premier astrophotographers that have a look in each of the image-processing software on the market today: our first is an overview of PixInsight with guest expert Warren Keller.
Watch a Q&A with two astronomers on the promise of Hubble's successor telescope, courtesy of The Kavli Foundation. Scientists have unveiled a bold proposal for a giant new space-based telescope that would be far more powerful than today's observatories. Called the High Definition Space Telescope (HDST), the instrument is essentially a supersized Hubble Space Telescope,…
