Bubble Nebula

NGC 7635 / Sharpless 162 / Caldwell 11, NGC 7538, M52 / NGC 7654

This is an actual bubble - altough it is 7 light-years across. That is 1.5x the distance to the nearest star to us. The hot young star in the center of the bubble is shedding its outer layers (it is a Wolf-Rayet star, SAO 20575). While that mass is being blown away from the star by the stellar wind it is also excited by the intense radiation. The nearby molecular cloud is glowing for the same reason. This star is going to become a supernova in about 10-20 million years and will collapse into a black hole.

Pinwheel Galaxy

M101 / NGC 5457 / SN 2023ixf

Altough our images often (though unintentionally) feature small extremely far & faint galaxies, M101 is the furthest away target that we have choosen so far. It is a whooping 21 million light-years away! Something to think about: if M101 was bright enough for the naked eye to see, it would look almost exactly the same size as the full Moon; it is however 517,383,697,916,666x further away than the Moon; so, how big is it??

M53

NGC 5024

This globular cluster was discovered in 1775, but it is a truly ancient object, 12.6 billion years old, only 1 billion years younger than the Universe itself. Another fact that makes it outstanding is that there are many first-generation stars in this cluster. As in, they were not formed from matter generated by previous stars, but are the first concentrations of mass.

Pleiades

M45 / Seven Sisters / Kiʹmah

Kiʹmah is possibly a reference to Pleiades in Amos 5:8:
The One who made the Kiʹmah constellation and the Keʹsil constellation,
The One who turns deep shadow into morning,
The One who makes day as dark as night,
The One who summons the waters of the sea
To pour them out on the surface of the earth
—Jehovah is his name."

Triangulum

M33 / NGC 598

Triangulum is the smallest spiral galaxy in the Local Group (us, Andromeda, the Magellanic Clouds and a few more neighbours). It is thought to be satellite galaxy of Andromeda as they are moving towards us together. In 4 billion years all three galaxies might merge into one big elliptical galaxy!

Andromeda Galaxy

M31 / NGC 224

The Andromeda Galaxy is the closest neighboring galaxy, a mere 2.5 million light-years away. It is the only galaxy visible to the naked eye - but just barely. The galaxy is made up of around 1 trillion stars.
