These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus.
This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively.
Can you see the “wizard”? Hint: he’s lying on his back in this image.
For fun, here’s a version with the stars removed using AI software:
Hoag’s Object is the weirdest galaxy I know of; it is a “ring galaxy” – a very rare galaxy type that’s just a galactic core of stars, surrounded by a ring of stars that’s seemingly disconnected from its core. This galaxy has always captured my imagination. Just look at this image from the Hubble Space…
It’s not the title of a children’s story – it’s a pair of galaxies 30 million light-years away that look like, well, a whale and a hockey stick. Officially their names are NGC 4631 and NGC 4656.
About 10 million light-years away within the constellation Camelopardalis lies NGC2403. It doesn’t get much love, but it was really an oversight in the famous Messier catalog that defines the most popular deep-sky objects. So let’s give it a little attention, and reflect on the fact that the light we’re seeing from this galaxy started…
Try saying that three times fast! Fortunately, the “Silver Sliver Galaxy” has a formal name that’s easier to pronounce: NGC 891. It’s about 30 million light-years away, and is thought to be very similar to what our own Milky Way galaxy would look like when viewed edge-on. Explore the wider-field image; click on it for…
(Image credit: ddmitr, iStockPhoto.com) Every picture on this site was taken from a suburban driveway in a “red zone” on the light pollution map, literally underneath a streetlight. Every year more subdivisions and apartment buildings spring up in my city, and light pollution from the metro Orlando area just keeps getting worse. There are four…
If you look at the constellation Orion in the winter night’s sky, the center of Orion’s “sword” is not a star at all – it is the brightest nebula in our sky, M42 or the Great Nebula of Orion. Sitting right on top of it is technically another nebula designated M43, and above that is…
