Good evening, Rallypoint, and welcome to the February 8th edition of Astronomy Picture of the Day (APOD): " Stellar Wind Shaped Nebula RCW 58." We are back in the southern hemisphere again for this look at a nebula produced by a Wolf-Rayet star. What's a Wolf-Rayet star? Like today's write-up says: 100 times as massive, a million times more luminous, and with 30 times the surface temperature as our Sun. What causes this? Once a star exhausts its core hydrogen supply, it moves on to fusing heavier elements and ejecting their outer layers via stellar winds. As you can see, the results are spectacular
In this case, we are looking at Wolf-Rayet (WR) 40 and nebula RCW 58. They both lie about 13,000 light years away in the constellation Carina.

Thank you my space-exploration advocate friend and brother-in-Christ Maj William W. 'Bill' Price for posting the Tuesday, February 8, 2023 Astronomy Picture of the Day (APOD): Stellar Wind Shaped Nebula RCW 58

APOD "Explanation: Imagine traveling to a star about 100 times as massive as our Sun, a million times more luminous, and with 30 times the surface temperature. Such stars exist, and some are known as Wolf Rayet (WR) stars, named after French astronomers Charles Wolf and Georges Rayet. The central star in this image is WR 40 which is located toward the constellation of Carina. Stars like WR 40 live fast and die young in comparison with the Sun. They quickly exhaust their core hydrogen supply, move on to fusing heavier core elements, and expand while ejecting their outer layers via high stellar winds. In this case, the central star WR 40 ejects the atmosphere at a speed of nearly 100 kilometers per second, and these outer layers have become the expanding oval-shaped nebula RCW 58."
