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…
Would you go into space if you knew your bones would turn into “pee brittle”? Dr. Michelle Thaller explores the effects of space on the human body.
