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,…
