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.

Tau Herculid Meteor Shower

The Tau Herculid meteor shower/outburst was a bust last evening, but still came away with a few nice captures and some lessons learned. The biggest lesson was learning my all-sky dome camera tends to overheat the equipment inside, yikes, temperatures inside hit about 58C (136F). We had almost 600 people watching our live stream from all over the world and had a blast chatting through the event and sharing observations from your locations. This image shows the best meteor captured during this event from my backyard. I’ve highlighted the Big Dipper (in Ursa Major) and Keystone (in Hercules) asterisms for reference.

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.

A star must have at least 8 times, but no more than 40 to 50 times, the mass of the Sun (M☉) to undergo this type of explosion. Type II supernovae are distinguished from other types of supernovae by the presence of hydrogen in their spectra. (Wikipedia).

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.

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 the area.

IC1396 Elephant Trunk Nebula in False SHO

This is the faint emission nebula designated as IC 1396 in the constellation Cepheus. This region is energized by the bright, bluish central multiple star HD 206267. You can see the Elephant’s Trunk Nebula, IC 1396A, on the lower edge of this image. This has been processed using false SHO (Hubble Palette) in PixInsight. From NASA APOD, “Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff.”

Campbell’s Hydrogen Star

I found this object to be interesting, although not very photogenic. The reddish-orange “star” in the central part of the image is called Campbell’s Hydrogen Star. Astronomer William Wallace Campbell spotted this unusual star-like object through a visual spectroscope at Lick Observatory in 1893. He could tell immediately from its spectrum that, despite its stellar appearance, he was not seeing an ordinary star at all. Instead, he had spotted an uncharted planetary nebula. With some extreme processing, I could make out the small reddish disk, but no central star.

North American Nebula in Cygnus - NGC 7000

The North America Nebula (NGC 7000) is an emission nebula in the constellation Cygnus. Can you see how it looks like the North American continent complete with a prominent Gulf of Mexico? The name “North America Nebula” was coined by Dr. Max Wolf (ref: Burnham’s Celestial Handbook, Volume 2, by Robert Burnham Jr.) no doubt from his work with E.E. Barnard on dark nebulae. No summer imaging session is complete without putting a little bit of time on this deep space object.
The North America Nebula covers a region more than ten times the area of the full moon, but its surface brightness is low, so normally it cannot be seen with the unaided eye (Wikipedia).

Planetary Nebula NGC 6781

NGC 6781 is a planetary nebula a few thousand light years away in the constellation Aquila. The planetary nebula is about two light-years across. Within NGC 6781, shells of gas blown off from the faint, but very hot, central star’s surface expand out into space. These shells shine under the harsh ultraviolet radiation from the progenitor star in intricate and beautiful patterns. The central star will steadily cool down and darken, eventually disappearing from view into cosmic oblivion (https://www.eso.org/public/images/ngc6781-potw/).
These nebulae are formed when a star begins reaching its end of life. The star begins throwing off shells of gas that expand away from the star. This forms a ring of hot ionized gas that we see as a planetary nebula. If you look closely, you can see a small blue star in the center of the nebula, this is the star that created the nebula.

Elliptical Galaxy Messier 86 (M86)

Messier 86 (also known as M86 or NGC 4406) is an elliptical galaxy in the constellation Virgo. Messier 86 is linked by several filaments of ionized gas to the severely disrupted spiral galaxy NGC 4438 (on the right side of my image), indicating that M86 may have stripped some gas and interstellar dust from the spiral. Messier 86 has a rich array of globular clusters, with a total number of around 3,800. Its halo also has a number of stellar streams interpreted as remnants of dwarf galaxies that have been disrupted and absorbed by this galaxy. (ref: Wikipedia).
