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,…

Capturing the Earth and sky in one great composition is surprisingly easy.
Getting started in astrophotography has never been easier.
Chances are you already own a great planetary camera, but didn’t know it.
Satellite dwarf galaxies orbiting the Milky Way should help scientists better grasp the universe's evolution while also homing in on dark matter's identity.
Courtesy of The Kavli Foundation, Sky & Telescope is featuring an in-depth Q&A with two astrophysicists and a theoretical physicist on what the Large Synoptic Survey Telescope will teach us about dark matter and dark energy.
Recently, two high-profile experiments released new data and analyses of the universe’s earliest light. Here, three preeminent scientists discuss the latest results, what they mean for the theory of cosmic inflation, and what we can expect to learn about the very early universe in the coming decade.
Scientist George Efstathiou weighs in on the latest results from the Planck satellite and what they say about cosmic inflation, the first stars, and more.
Sky & Telescope features a Q&A between The Kavli Foundation and three astrophysicists who discovered two enormous and unexpected structures radiating from the center of our galaxy. They discuss what these mysterious bubbles can tell us about the history of the Milky Way and how they could help in the search for dark matter.
