M27 Nebula
While hunting for comets in the skies above 18th century France, astronomer Charles Messier diligently kept a list of the things he encountered that were definitely not comets. This is number 27 on his now famous not-a-comet list. In fact, 21st century astronomers would identify it as a planetary nebula, but it's not a planet either, even though it may appear round and planet-like in a small telescope. Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core. The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. Known by the popular name of the Dumbbell Nebula, the beautifully symmetric interstellar gas cloud is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula. This spectacular color image incorporates broad and narrowband observations recorded by the 8.2 meter Subaru telescope.

The Dumbbell Nebula
M27/NGC 6853 is a planetary nebula in Vulpecula, at a distance of about 1,360 light years. The central star, a pre-white dwarf, is estimated to have a radius which is 0.055±0.02 R☉ which gives it a size larger than any other known white dwarf. The central star mass was estimated in 1999 by Napiwotzki to be 0.56±0.01 M☉.
This object was the first planetary nebula to be discovered by Charles Messier in 1764. it is easily visible in binoculars and small telescopes.

#SpaceScience Image of the Week: The Little Fox and the Giant Stars
Situated 8000 light-years away in the constellation #Vulpecula – latin for little fox – the region in the image is known as Vulpecula OB1. It is a ‘stellar association’ in which a batch of truly giant ‘OB’ stars is being born.
The vast quantities of #ultraviolet and other radiation emitted by these stars is compressing the surrounding cloud, causing nearby regions of dust and gas to begin the collapse into more new stars. In time, this process will ‘eat’ its way through the cloud, transforming some of the raw material into shining new stars.

Tonight's Sky: August 2018 | HubbleSite
Save the date to watch the peak of the Perseid meteor shower—an always-anticipated feature of the night sky—August 12 and 13th. This month, backyard telescopes will also reveal sunlight reflecting off the clouds of Venus’s thick atmosphere and the Ring Nebula, an expanding shell of glowing gas in the constellation Lyra.

Zooming in on Nova Vul 1670 in constellation of Vulpecula
This video sequence takes the viewer deep into a rich part of the northern Milky Way in the constellation of Vulpecula (The Fox), close to the more famous constellation of Cygnus (The Swan). This spot was the location of a bright star that appeared in 1670 and was recorded by many astronomers at that time.
New observations made with APEX and other telescopes have now revealed that the star that European astronomers saw was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimetre telescopes was needed before the mystery could finally be unravelled more than 340 years later.
The answer is a spectacular collision between two stars, more brilliant than a nova, but less so than a supernova, which produces something called a red transient. These are a very rare events in which stars explode due to a merger with another star, spewing material from the stellar interiors into space, eventually leaving behind only a faint remnant embedded in a cool environment, rich in molecules and dust. This newly recognised class of eruptive stars fits the profile of Nova Vul 1670 almost exactly.

One for the joy division fans
Originally shared by ****
From the constellation of Vulpecula.
In 1967, the first pulsar was observed by Jocelyn Bell Burnell and Anthony Hewish. The word pulsar is a portmanteau of "pulsating star."
Initially dubbed "LGM-1" (a humorous nickname meaning "Little Green Men"), the pulsar emitted radio waves, each separated by 1.33 seconds, which adhered to the conventions of sidereal time. Sidereal time (for example) is a reckoning of the Earth's movement relative to a fixed star.
Renamed CP 1919 (and with a slew of additional designations to follow), the discovery was soon featured in the massive Cambridge Encyclopedia of Astronomy. A particular image from that book caught the attention of the English rock band Joy Division in the 1970s. They took the image to graphic designer Peter Saville for a possible album cover adaptation.
Saville described the image as a “comparative path demonstration of frequency from a signal of a pulsar.” Each horizontal line, reaching a series of peaks close to the middle of the graph, was observed data from the Burnell and Hewish pulsar. Shown stacked, the composite image portrayed a "comparative chart of the frequency and the accuracy of this signal.”
So, thanks to a particularly striking data visualization, Joy Division's debut album Unknown Pleasures contains iconic art (Saville reversed the radio wave image from black-on-white to white-on-black) which likely encouraged purchases without a single note being heard.
