Messier 38 (also known as M38 or NGC 1912) is an open cluster in the Auriga constellation.
It was discovered by Giovanni Batista Hodierna before 1654 and independently found by Le Gentil in 1749. M36 and M37, also discovered by Hodierna, are grouped together with M38 at a distance of about 3,420 light years away from Earth.

NGC 1491 is a bright nebula in the constellation of Perseus. It is also known as LBN 704.
NGC 1491 (also listed in the Sharpless Catalog as SH2-206) is an emission nebula, which means it is a cloud of ionized hydrogen gas and a stellar nursery. The nebula is primarily illuminated by the bright star near the center of this image. This star is not only the primary source of the ultraviolet radiation that is lighting up the nebula, it is also generating an energetic stellar wind that is eroding away the gas of the nebula. At the brightest region of this image near that star, a subtle "bubble" might be seen near that star.
