¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2021 March 22 [2]See Explanation. Moving the cursor over the image will bring up an annotated version. Clicking on the image will bring up the highest resolution version available. From Auriga to Orion Image Credit & Copyright: [3]Alistair Symon Explanation: What's up in the sky from Auriga to Orion? Many of the famous stars and nebulas in this region were captured on 34 separate images, taking over 430 hours of exposure, and digitally combined to reveal the [4]featured image. Starting on the far upper left, toward the constellation of Auriga (the Chariot driver), is the picturesque [5]Flaming Star Nebula (IC 405). Continuing down along the bright arc of our [6]Milky Way Galaxy, from left to right crossing the constellations of the Twins and the Bull, notable appearing nebulas include the [7]Tadpole, [8]Simeis 147, [9]Monkey Head, [10]Jellyfish, [11]Cone and [12]Rosette nebulas. In the upper right quadrant of the image, toward the constellation of Orion (the hunter), you can see [13]Sh2-264, the half-circle of [14]Barnard's Loop, and the [15]Horsehead and [16]Orion nebulas. Famous stars in and [17]around Orion include, from left to right, orange [18]Betelgeuse (just right of the image center), blue [19]Bellatrix (just above it), the [20]Orion belt stars of Mintaka, Alnilam, and Alnitak, while bright [21]Rigel appears on the far upper right. This stretch of sky [22]won't be remaining up in the night very long -- it will be setting continually earlier in the evening as [23]mid-year approaches.
