Around the Moon in 28 Days: Lunar Observing for Beginners is a self-paced course that includes notes along, dozens of maps, and illustrations to take you on a tour of the Moon’s surface over each day of the nearly month-long lunar cycle. You’ll learn to find nearly 200 distinct features on the Moon’s surface, all of which you can see with a small t...

The Taurus Molecular Cloud

Not far from the Pleiades and Hyades star clusters along the northern Milky Way lies the coal-black fingers of the Taurus Molecular Cloud, the nearest star-forming region to Earth. Unlike the more famous Orion star factory, with the dazzling Orion Nebula and associated bright blue-white stars, the TMC is not well known to most stargazers. That’s because it doesn’t offer much to see, with no bright nebulae and just a dark and sooty network of tendrils that span more than 30o of sky. But the TMC is the nearest star-forming region to Earth, making it of considerable interest to astronomers. It’s also a rewarding target for astrophotographers who can capture its structure against the starry background in the constellations Taurus and Auriga [Read more…] about The Taurus Molecular Cloud

Five Favorite Images from 2020

To call me an astrophotographer would be an overstatement. But that doesn’t stop me from bringing a camera along when stargazing on a clear night to complement some casual visual observations. No image can reproduce what it’s like to look through a telescope or binoculars, especially in dark sky when the eye beholds the scintillation of stars and silver-white nebulae and galaxies against the black matte of the background universe. But images have the advantage of permanence, to some degree at least, and of leaving a record of what we’ve seen and where we’ve been in the night sky over the months and years [Read more…] about Five Favorite Images from 2020

Was the Christmas Star Real?

O star of wonder, star of night,
Star with royal beauty bright,
Westward leading, still proceeding,
Guide us to thy perfect light.

The Christmas Star – it may be the most famous “star” in history. But was it real? Mentioned just once in the gospel of Matthew, the “Star of Bethlehem”, or the “Christmas Star”, may have guided three wise men from the East in search of a newborn king. A few words written on a scroll two thousand years ago isn’t much to go on, but astronomers have a few ideas that may explain the apparition of a star near the time of the birth of Jesus [Read more…] about Was the Christmas Star Real?
