Gaze at the Majestic Swan Nebula Tonight!

If you're an astronomy enthusiast or just a casual stargazer, mark your calendars for a spectacular view this Thursday! High up in the southern sky at around 4 A.M. local time, the breathtaking Swan Nebula, also known as M17 or the Omega Nebula, will be gliding gracefully through the constellations of Sagittarius.

Without the Moon’s light interfering, this is the perfect opportunity to catch a glimpse of this cosmic wonder. The Swan Nebula shines brightly at magnitude 6, making it possible to spot even with binoculars if you can find a dark viewing spot. Positioned just 2.6° southwest of the bright star Gamma Scuti, it’s not too far from the Teapot asterism in Sagittarius.

What Does the Swan Nebula Look Like?

The Swan Nebula spans about 11 arcminutes and has a striking shape resembling that of a swan—complete with a long, flat body and a gracefully arched neck! Depending on your viewing conditions, it might even remind you of the number 2 or a checkmark.

For a richer view, consider using a telescope outfitted with an OIII filter. If you have access to a large telescope (8 or 10 inches), you could be rewarded with an even more spectacular sight: a mirror-image of the curved neck that transforms our avian friend into the Greek letter Omega (Ω), giving rise to its other famous name.
