NASA Astronomy Picture of the Day (2025-09-10): The Great Lacerta Nebula
It is one of the largest nebulas on the sky -- why isn't it better known? Roughly the same angular size as the Andromeda Galaxy, the Great Lacerta Nebula can be found toward the constellation of the Lizard (Lacerta). The emission nebula is difficult to see with wide-field binoculars because it is so faint, but also usually difficult to see with a large telescope because it is so great in angle -- spanning about three degrees. The depth, breadth, waves, and beauty of the nebula -- cataloged as Sharpless 126 (Sh2-126) -- can best be seen and appreciated with a long duration camera exposure. The featured image is one such combined exposure -- in this case taken over three nights in August through dark skies in Moses Lake, Washington, USA. The hydrogen gas in the Great Lacerta Nebula glows red because it is excited by light from the bright star 10 Lacertae, one of the bright blue stars just to the left of the red-glowing nebula's center. Most of the stars and nebula are about 1,200 light years distant. Jigsaw Universe: Astronomy Puzzle of the Day
🚀 **Upcoming Space Launch** 🚀
🌌 **Mission Name**: Soyuz 2.1b/Fregat | Glonass-K1 No. 18
🗓️ **Launch Date**: 2025-09-13T02:30:00Z
🚀 **Rocket**: Soyuz 2.1b/Fregat
📖 **Details**: Glonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
