The Great ‘South American Eclipse’ of 2019

By Filed Under: Celestial Events


Observers in a narrow band across the southern Pacific Ocean and north-central Chile and Argentina enjoyed a rare spectacle today: a total solar eclipse. The lovely seaside towns of La Serena and Coquimbo, Chile, enjoyed two minutes and thirteen seconds of totality, and observers at some of the world’s great astronomical observatories got in on the fun. This is the first total solar eclipse visible anywhere since the ‘Great American Eclipse‘ of August 21, 2017. The next total solar eclipse occurs on December 14, 2020, once again across the South Pacific, Chile, and Argentina.

The Christmas Comet of 2018

The year 2018 winds down with the apparition of the modest but easily observable Comet 46/P (Wirtanen). This periodic comet will not rival some of the better “Comets of Christmas Past” such as Comet McNaught in 2006, Comet Hale-Bopp as it brightened towards the end of 1996, or even the relatively disappointing Comet Kohoutek in 1973. But Comet Wirtanen will grow bright enough to see with binoculars and, in dark sky, with the naked eye as it passes through some of the most prominent constellations of the season. It’s a great excuse to dust off your optics and get outside to enjoy the solar system in action and share the view with those around you [Read more…] about The Christmas Comet of 2018

A Video Retrospective of an Extraordinary Solar Eclipse

By Filed Under: Celestial Events

It was the most watched event in astronomical history, and it called forth awe from hardened scientists, barstool astronomers, and small children alike. It was the Great American Eclipse of August 21, 2017. It was a much-hyped and all-to-fleeting event, and like you, I wish I could see it again. We can’t, of course, but we can enjoy the video and images of expert astrophotographers who spent much time and effort documenting this extraordinary eclipse. Here are a few of my favorite videos below… [Read more…] about A Video Retrospective of an Extraordinary Solar Eclipse

The Tears of St. Lawrence

Perseid meteors appear to emanate from a point (called a radiant) in the northern constellation Perseus. The peak of the meteor shower occurs on or about August 12 each year. Image credit: NASA.

It’s the best celestial show of the northern summer months, one that can be enjoyed without a telescope, camera, or much expertise in celestial matters at all. It’s the Perseid meteor shower, an annual event in which sand-sized bits of an ancient comet streak through the Earth’s upper atmosphere and elicit “oohs and ahhs” from experienced and untutored stargazers alike.

The Sky This Month – February 2018

By Filed Under: Celestial Events

The constellations Orion, Canis Major, Taurus, and Auriga dominate the northern sky this month, while southern observers see these same groups along with Puppis, Carina, and Vela, constellations which harbor some of the best sights the night sky has to offer. No matter where you live, grab a telescope or binoculars and head out to take a look. This February is also a slightly unusual month because there’s no full Moon. January had two, the last of which happened on the final day of the month along with a spectacular lunar eclipse that coincided with the Moon’s closest approach to Earth. The video above shows a splendid summary of the event made by Griffith Observatory in Los Angeles. And if you enjoyed waking early to see the planets Mars, Jupiter, and Saturn in January, then you’ll have even more fun this month as each slowly grows bigger and brighter in the pre-dawn sky. Here’s what to see in the night sky this month. [Read more…] about The Sky This Month – February 2018
