In today's image, we see the Iris Nebula. This is an example of a reflection nebula which light from a hot star is scattered off of dust grains around the star. The blue color is because the blue light is more effective;y scattered than red light would be. My podcasts are available in video form through this YouTube Channel.

In today's image, we see dark nebulae in the constellation of the Chameleon. The dust that makes up these nebula is formed in the outer atmospheres of supergiant stars at the end of their lives and then expelled out into the universe upon their deaths.

In today's image, we see the Villarrica volcano in Chile as it erupts. Earth is one of the few objects with active volcanoes like this. The other active object would be Jupiter's moon, Io.

In today's image, we see what are known as cometary globules. While these have nothing to do with comets, they do bear a resemblance to the comets we find in our solar system. They are actually compact regions where stars are currently forming in our galaxy. My podcasts are available in video form through this YouTube Channel.

In today's image, we see the galaxy known as the Tadpole Galaxy for the long tail stretching away from it. The tail is caused by a previous interaction with another galaxy which has caused material to be pulled out of the galaxy in a tidal stream.

In today's image, we see the Triangulum Galaxy, also known as M33 which is one of the three large spiral galaxies in our local group. We also see a meteor that happened by chance to appear in the frame as the image was being taken. The meteor is within our atmosphere while the Galaxy is about 3 million light years away.

In today's image, we see a portrait of the solar system showing 6 of the 8 plates in our solar system with Mercury and Mars not being visible because of their position relative to the glare of the Sun.
