Discovered by Anglo-German Astronomer William Herschel on November 17, 1784 and located approximately 68 million light-years distant in the southern constellation Fornax, is NGC (New General Catalog) 1385. Like the Milky Way, NGC-1385 is a Barred Spiral Galaxy but 40% smaller at 70,000 light years in diameter. The central ‘bar’ is the result of density[…]
On August 8 and visible now during the summer, the faint cataclysmic variable star RS Ophiuchi at over 6,500 light-years distant brightened from magnitude 11.2 to 4.8 during the August 8-9, 2021 time frame. It went from a threshold small-telescope object to naked-eye visibility within 24 hours. Irish amateur Astronomer Keith Geary was the first[…]
Six Hour Time Lapse Video Showing the Perseid Meteor Shower’s Radiant Point The Perseid meteor shower is an annual event that occurs during the 2nd week in August as the Earth passes through the same debris field left behind by comet Swift–Tuttle. The Radiant Point is the imaginary point on the sky that they appear[…]
In this video, we present three favorite star clusters of summer for observers in the Northern Hemisphere. We open looking due south at twilight for mid-northern latitudes and note brilliant Venus setting as it follows the sun and Scorpio on the meridian with Sagittarius due east. Scorpio with red Supergiant Antares, the heart of the[…]

A quick video showing the placement of the Virgo Cluster of galaxies with the massive elliptical galaxy Messier-87 at its center. Imaged with the Hubble Space Telescope, M-87 is shown here surrounded by thousands of globular star clusters. Our Milky Way galaxy, a member of the Local Cluster of Galaxies is, in turn, a member[…]
In a stunning image, worthy of publication on NASA’s Astronomy Picture of the Day or, as a new category, as “Astronomy Picture of the Year”, Finnish Astrophotographer JP Metsavainio has produced a GigaPixel class image that took 12 years and more than 1,250 hours to produce! Join Dr. Jim Daly of Astronomy For Change has[…]
The object discussed in this article, Terzan5, was featured as the Astronomy Picture of the Day, APOD for 21 September, 2016 Astronomy Picture of the Day In a few articles I’ve touched upon a poorly understood class of objects known as Globular Clusters. These objects and the stars in them are galactic relics, timeposts that[…]
Looking up at the shimmering sapphire set low in the western sky towards midnight, Arcturus, we are reminded that another summer is here, that spring is gone and that Father Time continues his cadence, marking the years; it is a reminder that everything is changing and growing; it is solace in an insane world and[…]
