The featured image is a composite showing many meteors trails
streaking across a sky featuring the familiar constellation of Orion.
In the foreground two people sit in adjoining chairs facing away
from the camera, one holding a wand with a glowing star at the end.
Please see the explanation for more detailed information.

Leonid Meteors Through Orion

There will be a next meteor. It's hard to know during a shower. It's a good idea to find a place where you can sit and look up at the stars. It is possible to share this experience with a friend. The view from China is from the South China Sea and shows the peak of the meteorite shower in the year 2022. There were isolated and added to a foreground image. From this place and time, there were meteorites that streaked across the sky. There is a red planet near the top of the picture. Two people shown celebrating their common birthday this month are now married.

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.

The featured image shows a grand skyscape with a brown desert road in the foreground and a sky containing
the Milky Way galactic band complete with a large red glow on the right which is the dim Gum Nebula. The
LMC galaxy is also visible. Please see the explanation for more detailed information.

The Gum Nebula Supernova Remnant

Explanation: Because the Gum Nebula is the closest supernova remnant, it is actually hard to see. Spanning 40 degrees across the sky, the nebula appears so large and faint that it is easily lost in the din of a bright and complex background. The Gum Nebula is highlighted nicely in red emission toward the right of the featured wide-angle, single-image photograph taken in late May. Also visible in the frame are the Atacama Desert in Chile in the foreground, the Carina Nebula in the plane of our Milky Way galaxy running diagonally down from the upper left, and the neighboring Large Magellanic Cloud (LMC) galaxy. The Gum Nebula is so close that we are much nearer the front edge than the back edge, each measuring 450 and 1500 light years respectively. The complicated nebula lies in the direction of the constellations of Puppis and Vela. Oddly, much remains unknown about the Gum Nebula, including the timing and even number of supernova explosions that formed it.
