Improve your deep-sky images with this innovative program.
Video can boost your telescope’s reach by leaps and bounds.
We finally know the ingredients that fire up a particular kind of supernova. Four researchers explain why a better understanding of how certain stars die can help reveal the evolution of the cosmos and its galaxies.
A new exoplanet closely matches what astronomers think Jupiter looked like in its infancy. Astrophysicist Bruce Macintosh of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford discusses why this discovery might help us understand how planets arise.
Follow these simple suggestions to get the most out of your CCD images.
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.
Sky & Telescope's year-at-a-glance guide to celestial happenings is a symphony of detailed calculations and clear, elegant design.

Three astrophysicists discuss preparations for three recently funded dark matter experiments, and the likelihood that one of them will strike gold.
Most of us are familiar with the Seven Sisters, but have you met their brothers? Learn how to find more Pleiades than first meet the eye.
October's a perfect time to see the zodiacal light, a tapering tower of comet dust standing high in the eastern sky before dawn. Here's how to find it.
Ten thousand stars bedazzle the eye on a dark night. Wait, how many?
With a subtle beauty all its own, the earthshine we see glowing in the lunar night invites us to consider Earth's many connections to the Moon.
Locally, spacetime is curved by the presence of massive objects. The total mass and energy density of the universe also has an effect on the overall curvature of space.
There was no “before the Big Bang"—the Big Bang created both time and space as we know it.
Dark matter is a mysterious type of matter that doesn't interact with any form of electromagnetic radiation, i.e., light. Although we’ve never detected dark matter directly, a large amount of evidence points to its existence.
Just how quickly is the universe expanding? Cosmologists attempt to answer this question in terms of the Hubble Constant, but the exact value of this constant is still a topic of debate.
