If you want the best results from your eclipse photos, you'll need to do some processing. Equipment Editor Sean Walker walks us through processing photos from the 2010 Easter Island eclipse.
When limited time and a powerful on-shore wind scrapped the author’s plans for photographing the eclipse, he simply propped his telescope on a rock wall and hit the shutter button — with stunning results.
Join S&T's live webinar to learn the secrets of how to take awe-inspiring time-lapse videos of the Earth and sky at night.
Learn some of the classic stargazing sights that can be best viewed through a smaller telescope.
Much to their surprise, scientists are finding dozens of black holes deep within densely packed collections of stars called globular clusters. Astrophysicists are using a record-breaking computer simulation to learn their secrets, including whether the clusters gave rise to recently observed ripples in space-time.
With all the interest in August’s sky spectacular, it’s no surprise that you can find lots of great information about solar eclipses. Here are some favorite resources chosen by the editors of Sky & Telescope magazine: Books About Eclipses In the Shadow of the Moon: The Science, Magic, and Mystery of Solar Eclipses by Anthony…
Try this easy technique to roughly polar-align your telescope mount during the day using your smartphone and a planetarium app.
Why are some scientists world-famous but not others? Narrative, even one as simple as "starlight bends," turns out to be a powerful tool for making sense of science. In 1905 Albert Einstein published four papers that transformed our understanding of light, atoms, space, time, and energy. The world took no notice. Ten years later, still…
Find out how to remove light pollution from your astrophotos so you can have dark skies instead of red-brown ones.
The universe sings to us in gravitational waves, and we're starting to listen. Michelle Thaller discusses the discovery of gravitational waves and their unusual effects in her latest astronomy podcast.
How do you find out what stars are visible tonight? With a planisphere or "star wheel." It's easy!
You'll capture the night sky as it truly looks when you learn how to establish a proper white balance in your DSLR astrophotos.
Earth is a planet, too! Dr. Michelle Thaller explores how NASA investigates Earth using space-based satellites, and how that knowledge can save lives.
Join Sky & Telescope Contributing Photographer Babak Tafreshi for a live webinar to learn the secrets of stunning Milky Way photography.
Thanks to a record haul of new, ultra-distant quasars—powerhouses of light from the farthest reaches of the universe—astrophysicists can now piece together the rise of mighty objects in the early cosmos.
Dr. Michelle Thaller talks to two NASA astrobiologists on when and how we'll explore Europa's subsurface ocean, and what we might find there.
Here's what you need to know to navigate the heavens with a telescope and star atlas.
Purple halos around stars can be a problem when shooting with inexpensive camera lenses and telescopes. Here's how to fix them.
In astrophotography, to dither means to shift the pointing of the telescope slightly in random directions between exposures. Here's how it works, and why you should use it.
Dr. Michelle Thaller explores the story of how scientists discovered that the ozone layer was disappearing and how they moved to save it — and avert catastrophe.
Here's a great free download that uses a deck of playing cards to introduce you to the night's sky's constellations in a fun, entertaining way.
Here’s the info you’ll need to “save the date” for some of the top stargazing events in the U.S. and Canada for the coming year.
What’s inside a black hole? Wormholes? Alternate universes? If you fell into a black hole, only one thing’s for sure: its tidal forces would kill you.
Learn what a black hole is, what we mean by “singularity” and “ergosphere,” and why we think black holes are real.
Maybe this gift-giving season you got a shiny new telescope to call your own. Congratulations — you could be on your way to discovering many amazing far things in the night sky. Although most of them are so far and faint that just finding and detecting them is the challenge! Whether your new scope is…
