Sharpless 116 (Abell 71 )

SH2-116 is a small nebula that is also known as Abell 71 and sits not from the bright star Deneb in Cygnus. This object was first classified as a planetary nebula but recent studies show it to be an HII region instead. This object is best imaged using a larger telescope because of its size and some of the nice structure it has. However, SH2-115 is right next to it and a larger field of view can easily pick up both of them. The nebula surrounding SH2-116 is indeed part of SH2-115.

Sharpless 108 (Gamma Cygni Nebula)

The Gamma Cygni Nebula, also known as the Sadr Region or IC 1318 or Sharpless 108, is a diffuse emission nebula that can be seen around Sadr (Gamma Cygni), the star at the center of the Northern Cross, which marks the heart of Cygnus, the Swan. Despite the name, the star and the nebula are unrelated. Even though it looks embedded in the nebulosity, Sadr is approximately 1,800 light years distant, while the nebula is much further away, at 4,900 light years.

The Gamma Cygni Nebula is considered an emission nebula because it is ionized by the radiation of the nearby stars and it emits visible light as a result. The visible portion of the H II region stretches over an area more than 100 light years across. The nebula is illuminated by an O9-class star which is visually obscured by interstellar material.

Messier 27 (The Dumbbell Nebula)

 

Is this what will become of our Sun? Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae on the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27, featured here in colors emitted by hydrogen and oxygen. Understanding the physics and significance of M27 was well beyond 18th century science. Even today, many things remain mysterious about bipolar planetary nebula like M27, including the physical mechanism that expels a low-mass star's gaseous outer-envelope, leaving an X-ray hot white dwarf.

M11 - Wild Duck Cluster

 

Featured above is the Wild Duck star cluster (also known as M11) sitting in the constellation of Scutum the Shield. Composed of nearly 3,000 stars, this compact grouping, one of the most compact open star clusters, lies some 6000 light years away. As viewed from the Northern Hemisphere it resides in the southern sky, within the glow of the Milky Way and between the constellations of Aquila and Sagittarius. Though it's highest in the sky in late summer and early fall, it can only be observed with a moderate-sized telescope. Detecting a duck of any kind in this cluster is no more challenging than identifying a shield in Scutum.

M2

 

Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation Aquarius, five degrees north of the star Beta Aquarii and it is one of the largest known globular clusters.

M2 is, under extremely good conditions, just visible to the naked eye. Binoculars or a small telescope will identify this cluster as non-stellar, while larger telescopes will resolve individual stars, of which the brightest are of apparent magnitude 13.1.

M2 is about 37,500 light-years distant from Earth. At 175 light-years in diameter, it is one of the larger globular clusters known. The cluster is rich, compact, and significantly elliptical. It is 13 billion years old and one of the older globulars associated with the Milky Way Galaxy.

M2 contains about 150,000 stars, including 21 known variable stars. Its brightest stars are red and yellow giant stars.

A rose made of galaxies Arp 273

 

Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus, and "it is thought that the smaller galaxy has actually passed through the larger one.
