Starship Asterisk*

M90 and IC 3583 (Arp 76) M90 (also known as NGC 4569) is a spiral galaxy that is part of the Virgo cluster. It is sometimes referred to as an anemic galaxy because of a dearth of star formation in its spiral arms. This is related to the stripping away of interstellar gas and material (ram pressure ...

Grand-Design Spiral Galaxy M100 M100 is a grand-design spiral galaxy that is bursting with star formation. Located in the constellation Coma Berenices, it is one of the largest members of the Virgo Cluster. Luminous extensions of its sweeping outer arms connect M100 with two satellite galaxies NGC ...

Sunflower Galaxy M63 The Sunflower Galaxy floats in the constellation Canes Venatici at a distance of about 30 million light-years from Earth. It is commonly referred to as a flocculent galaxy due to the lack of well-defined spiral arms in visible light; however, near infrared images reveal a symme...

Ceres crosses M100 Dwarf planet Ceres passes in front of spiral galaxy M100 on the night of March 26-27. Ceres is about 13.3 light-minutes away from Earth while M100 is about 56 million light-years further out. Image shows Ceres every 30 minutes from UT 00:22 - 06:52 on March 27, 2023. Image is a c...

Three Open Clusters in Gemini From left to right are open star clusters IC 2157, NGC 2158, and NGC 2168 (Messier 35). Like many people, the first time I saw NGC 2158 in a telescope I thought it was a comet. I was looking at M35 and noticed a soft fuzzy patch to the southwest. Higher magnification r...

That's a fine image! :D Your image made me curious about what is causing the "C" and the "L", so I decided to check images of NGC 7000 with stars. If you go to this image , you can see how the "C" stands out (at top center). The "L", to the lower right of the...

O Canada (North America) Nebula This is the Canada region of the North America Nebula (NGC 7000). I was unable to find information or designations for the prominent “L” and “C” structures. The image is an Ha/OIII bi-color mapped as red (Ha), green (80% OIII, 20% Ha), and blue (90% OIII, 10% Ha). I ...

All Galaxies Starless Hickson 44 Region This is the Hickson 44 galaxy group region in Leo. It is a 10-hour image captured without a filter. I carefully removed all of the stars and starlight artifacts by hand in Photoshop while preserving everything that was fuzzy or out-of-round. Lots of galaxies!...

NGC 7535 (left) and NGC 7538 (right) are star-forming nebulae that straddle the Cassiopeia - Cepheus border. NGC 7635 is commonly known as the Bubble Nebula. The bubble is formed from hot stellar winds from a star that is 45 times more massive than our Sun. Outflow from the star pushes cold interste...
