some of which can be seen around NGC 4907 in this image

Another theory is that the increased sunlight in the summer months is changing the amounts of photochemical haze produced

Astronomers believe that some of these more unusually shaped planetary nebulae are formed when the progenitor star is actually a binary system

The Twist in AB Aurigae Star Wall Art Size:Small (8 x 8) Credit: ESO/JThis image shows the disc around the young AB Aurigae star, where ESOs Very Large Telescope (VLT) has spotted signs of planet birth. Close to the centre of the image, in the inner region of the disc, we see the twist (in very bright yellow) that scientists believe marks the spot where a planet is forming. This twist lies at about the same distance from the AB Aurigae star as Neptune from the Sun. The image was obtained with the VLTs SPHERE instrument
