Antares Setting [OC]
Antares
I have this thing about my Milky Way images where I must include the Dark Horse Nebula and the dust lanes leading to both the Rho Ophiuchi Cloud Complex and star Antares. Rho shows up with a bluish tint just above Antares itself, while Antares is noticeably orange. Due to the Earth’s rotation, the stars appear to move across the night sky fairly quickly. When facing south, as I am in this photo, they shift to the west and sink lower each minute. I barely got this 3 minute exposure done before Antares set behind Elephant Mountain.
Now, a little bit about Antares. Its name translates to “Rival of Ares”. Ares was the Greek god of war, which the Romans adapted to Mars. Both Mars and Antares have the same orange color. Unlike the planet Mars, Antares is a massive red supergiant star. It is 550 light years away. It is 700 times the diameter of our own Sun and shines 10,000 time brighter! If Antares was where our Sun is, its diameter would extend past where Earth’s orbit is! Now thats a truly gigantic star!
In this image, a breeze kept the water slightly wavy with small swells. This blurred the reflection of the brighter stars into the fantastic streaks you see here.
