This image from the Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory shows the spectacular globular star cluster Messier 4. This great ball of ancient stars is one of the closest of such stellar systems to the Earth and appears in the constellation of Scorpius (The Scorpion) close to…

This image of the North American Nebula was captured in 2018 near Thornbury, Ontario by my friend Sailu Nemana. Several of the surrounding bright stars and star clusters within it are highlighted. The Pelican Nebula (at right) is formed by the dark dust of LDN 935. The re/pink colour is produced by ionized hydrogen gas.…

This simulated 3D model of the solar system shows the position of Earth on July 30 while it is crossing through the debris field dropped along the orbit of comet P/2008 Y12 (SOHO), producing the peak of the Southern Delta-Aquariids Meteor Shower. You can manipulate the model at the website https://www.meteorshowers.org/ Hello, Summer Stargazers! Here…

The magnitude 9 spiral galaxy is visible in medium-sized telescope under dark sky conditions. End-to-end the galaxy spans 11 arc-minutes, or one-third of the full moon’s diameter! While it didn’t make Charles Messier’s List,…
