At this time of year, just after darkness falls, we get to see the thickest part of the Milky Way extending over more than half the sky from Cygnus to Scutum to Sagittarius. And where there’s Milky Way, there are star clouds. Grab your binoculars or small telescope and take a tour of the best star clouds of a northern summer (and southern winter) with the recent article published in Sky & Telescope magazine. Inspired by the photographic work of E.E. Barnard in the early 20th century, this sky tour starts with the ‘Great Cloud’ of Sagittarius and works northwards, stopping to see many star clusters and dark nebula in and around these regions of shimmering starlight. It also includes visuals, especially the recent black-and-white film photography of James Cormier. Click on the image to the left to download the article on PDF format (it’s about 6MB). Then enjoy the tour!

Touring the Summer Triangle
While not a constellation itself, the Summer Triangle dominates the overhead sky in the northern summer and autumn months and guides stargazers to other stars, constellations, and deep-sky sights. The vertices of the triangle are marked by three bright stars Vega, Deneb, and Altair, each of which belong to true constellations Lyra, Cygnus, and Aquila, respectively. The image below shows the Summer Triangle rising as seen from mid-northern latitudes at 10 p.m. in mid July. The triangle is big: it spans about two full hand widths held at arm’s length. The triangle can be seen well south of the equator, too, above the northern horizon. Southern stargazers call it the “Northern Triangle” or the “Winter Triangle” [Read more…] about Touring the Summer Triangle
Share This:The Eta Carinae Nebula
The Eta Carinae Nebula, the jewel of the southern-hemisphere constellation Carina, the Keel, is the most spectacular example of an active star factory in all the heavens. The nebula is about 260 light years across, some seven times larger than the Orion Nebula. And while 7,500 light years away, five times farther away than Orion, it’s still easily visible to the even the most casual stargazer as a large frosty patch three times as wide as the full Moon in the Milky Way west of the constellation Crux, the Southern Cross [Read more…] about The Eta Carinae Nebula
Share This:Touring Queen Berenice’s Hair
Let’s take a look at the ancient constellation Coma Berenices, a faint group of stars tucked under the handle of the Dipper halfway between the stars Arcturus and Denebola in Leo’s hindquarters. There is something for everyone here: history and legend, a beautiful naked-eye star cluster that invites careful inspection, and dozens of galaxies to explore with a modest telescope. And armchair astronomers can contemplate the immensely distant Coma Cluster of Galaxies, some 300 million light years away, that first yielded evidence for the mysterious dark matter that makes up a good portion of the universe [Read more…] about Touring Queen Berenice’s Hair
Share This:Live Stream and Resources for the Total Solar Eclipse of April 8, 2024
On April 8, 2024, a total solar eclipse will pass in a narrow band across Mexico, the continental United States, and southeastern Canada. Millions of people live within a day’s drive of the narrow path of this eclipse, so it may be one of the most watched astronomical events in history. If you’re heading to the path of totality, or if you’re planning to observe the partial solar eclipse off the path of the lunar umbra, I wish you safe travels and clear skies! And if you’re not traveling, or if you’re facing clouds, or you simply want to know what’s happening with this rare celestial event, here are a few resources and readings about this eclipse and solar eclipses in general.
