Cygnus X-1 - Black Hole

While imaging and processing the The Tulip nebula, I was surprised to see I also captured the shock wave being produced from Cygnus X-1. It is the site of one of the first suspected black holes. Over the years the location of this X-ray source became more accurately determined. The X-ray source was found to lie very close to the position of a 9th magnitude star called HDE 226868. This star is a large blue supergiant, and its companion – the more compact of the two objects in the system – is thought to be between 20 and 35 solar masses. Since the largest possible mass of a neutron star can not exceed three solar masses, the compact object which is unseen, is almost certainly a black hole. These two objects share an orbital periodicity of 5.6 days.

Star-Forming Region Sh2-106

Sharpless 2-106, Sh2-106 or S106 for short, lies nearly 2,000 light-years from us. The nebula measures several light-years in length. It appears in a relatively isolated region of the Milky Way galaxy. A massive, young star, IRS 4 (Infrared Source 4), is responsible for the furious activity we see in the nebula. Twin lobes of super-hot gas stretch outward from the central star. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an "hourglass" shape.
Detailed studies of the nebula have also uncovered several hundred brown dwarfs. At purely infrared wavelengths, more than 600 of these sub-stellar objects appear. These "failed" stars weigh less than a tenth of our Sun. Because of their low mass, they cannot produce sustained energy through nuclear fusion like our Sun does. They encompass the nebula in a small cluster. (Ref: https://hubblesite.org/contents/media/images/2011/38/2932-Image.html)

The Shrimp Nebula - Sh2-188

Sh2-188 is a planetary nebula in Cassiopeia. It does not have an official name but is often called the "Shrimp Nebula" or even the "Dolphin Nebula" due to its shape. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is nearly circular in shape but is much brighter to the southeast (lower right) because the central star is moving rapidly in that direction. Faint wisps of gas can also be seen in the opposite direction.

NGC 6820 and NGC 6823

NGC 6823 is an open cluster and is surrounded by an emission nebula designated as NGC 6820 (also known as SH2-86). This pair is located roughly 6,000 light-years away in the constellation Vulpecula.
The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster, which is about 50 light-years across, is about two million years old and is dominated in brightness by many young, bright blue stars, packed in a Trapezium-formed region of about 1.3 x 0.7 light-years across. Outer parts of the cluster, involving pillars of the emission nebula, contain even younger stars.
The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by stellar winds and radiation from the brightest cluster stars. Remarkable dark globules of gas and dust (Bok globules) are also visible in the nebula. Bok globules, named after the Dutch astronomer Bart Bok (1906-1983), who proposed their existence in the 1940′s, are dark clouds of dense cosmic dust and gas within star-forming regions in which usually star formation takes place. They most commonly result in the formation of double or multiple star systems. (Ref: http://annesastronomynews.com).

Merging Galaxies in Draco - Arp 81

Arp 81 is a strongly interacting pair of galaxies, seen about 100 million years after their closest approach. It consists of NGC 6621 and NGC 6622. NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped behind its body. The collision has also triggered extensive star formation between the two galaxies. Scientists believe that Arp 81 has a richer collection of young massive star clusters than the notable Antennae galaxies (which are much closer than Arp 81). The pair is located in the constellation of Draco, approximately 300 million light-years away from Earth.

Bubble Nebula - NGC 7635

From Wikipedia: “NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.”

The Ghost of Cassiopeia - IC59 and IC63

IC 59 and IC 63 are found in the constellation Cassiopeia very near the bright star Gamma Cassiopeia. This set of objects is also known as the Ghost of Cassiopeia. Gamma Cassiopeia also has the informal nickname of Navi. The “IC” designation comes from a group of objects discovered between 1888 and 1907, most made possible by photography, and known as the Index Catalogue.
These nebulae are a combination of emission and reflection, they are located about 610 light years from Earth and are about 10 light years across. Gamma Cassiopeia provides the radiation to light up this area of dust and gas, eventually dissipating in the area.

Deneb - Alpha Cygni

Here is a quick view of the star Deneb in the constellation Cygnus
From Wikipedia - Deneb is a first-magnitude star in the constellation of Cygnus, the swan. Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross. It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. A blue-white supergiant, Deneb rivals Rigel as the most luminous first-magnitude star. However, its distance, and hence luminosity, is poorly known; its luminosity is somewhere between 55,000 and 196,000 times that of the Sun. Its Bayer designation is α Cygni, which is abbreviated to Alpha Cyg or α Cyg.

The Eastern Veil Nebula - NGC 6992 and 6995

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon). This is the Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995.

Spiral Galaxy Messier 94 (M94)

This is the spiral galaxy named Messier 94 (M94 or NGC 4736) found in the constellation Canes Venatici. It has an apparent magnitude of 8.99 and is about 16 million light-years away from Earth.
From NASA - New stars are forming at a high rate within the bright ring. This region is known as a starburst ring. The cause of this peculiarly shaped star-forming region is likely a pressure wave traveling outward from the galactic center, compressing the gas and dust in the outer regions. The compression of material means the gas starts to collapse into denser clouds. Inside these dense clouds, gravity pulls the gas and dust together until the temperature and pressure are high enough for stars to be born.

NGC 772 (Arp 78) The Nautilus Galaxy

When I first imaged The Nautilus Galaxy (NGC 772/ARP 78) I was fascinated by its shape, one spiral arm stretched outward from the center. This is probably an effect of being tugged on by a satellite galaxy designated as NGC 770 (the bright fuzzy ball of light at the eight o'clock position). NGC 772 is also listed as ARP 78 in the Arp Atlas of Peculiar Galaxies. This catalog was compiled by Dr. Halton C. Arp and it details 338 peculiar galaxies. It is estimated that NGC 772 is twice the size of our Milky Way Galaxy! If you are looking at this image on Facebook or on our web site, I’ve also included an annotated version of the image.

I’ve imaged this galaxy three times in the last seven years, each time bringing out new details from changes in camera sensor technology, software processing and experience.
I’m not sure who first coined the name “Nautilus Galaxy”, but I did find a reference from 2008 by Ruben Kier who states, “I find the shape of NGC 772 resembles the nautilus shell, as illustrated to the right, so I have called it the Nautilus Galaxy.” (REF: http://www.stardoctor.org/772.html) If you Google “Nautilus Shell” you’ll see what he is talking about.

Planetary Nebula NGC 40

From Wikipedia: NGC 40 (also known as the Bow-Tie Nebula and Caldwell 2) is a planetary nebula discovered by William Herschel on November 25, 1788, and is composed of hot gas around a dying star. The star has ejected its outer layer which has left behind a smaller, hot star with a temperature on the surface of about 50,000 degrees Celsius. Radiation from the star causes the shed outer layer to heat to about 10,000 degrees Celsius, and is about one light-year across. About 30,000 years from now, scientists theorize that NGC 40 will fade away, leaving only a white dwarf star approximately the size of Earth.

The Heart Nebula - IC1805

The Heart Nebula (IC 1805) lies about 7,500 light years away from Earth in the Perseus Arm of the Galaxy in the constellation Cassiopeia. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. The Heart Nebula is located adjacent to the Soul Nebula forming a view referred to as the Heart and Soul Nebula.
