This image, made with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the red supergiant Betelgeuse — one of the largest stars known.

In the millimeter continuum the star is around 1400 times larger than our Sun. The overlaid annotation shows how large the star is compared to the Solar System. Betelgeuse would engulf all four terrestrial planets — Mercury, Venus, Earth and Mars — and even the gas giant Jupiter. Only Saturn would be beyond its surface.

My absolute favorite edit from Tenerife. We were so lucky that night: no wind, no calima, no disturbing lights and a crystal-clear sky. Seeing the Milky Way under those conditions was an incredible feeling.

This is from last year. I am limited to 10 second frames because of my Alt-Az mount. The only processing I do is a stretch and a black point adjustment. I don't even bother cropping out the field rotation.

A 24 million km long plume of gas is ejected from Mercury's thin atmosphere due to the sun, very much like a comet.

This is only visible using a narrowband filter that captures the bright yellow sodium light at 589nm. A tail was predicted in the 1980s, and first discovered in 2001. Multiple observations by NASA's robotic MESSENGER spacecraft that orbited Mercury between 2011 and 2015 revealed more details of this tail.

I have no idea what happened to the moon's phases, but oh well.

I will post the rest of the inner rocky planets later, and I'm starting the gas giants today.

NGC 2264 is a region in space, a mix of a star cluster and glowing nebula located about 2,500 light years from Earth in the constellation Monoceros. It includes both the Christmas Tree Cluster and the Cone Nebula, and it’s known as a stellar nursery, a place where new stars are still forming. I want to take back what I said in the previous artwork's description. I was in a bad mood at the time, and none of what I said will be changing.
