The 'Hungry' Ghost Nebula: vdB 141 in Cepheus | Mayall Telescope

The 'Hungry' Ghost Nebula: vdB 141 in Cepheus | Mayall Telescope

The Hungry Ghost Festival on August 18 this year is one of the most eerie celebrations in Chinese culture. In Hong Kong, the city comes alive with vibrant rituals and community events that are steeped in superstition and rituals. The festival is thought to have roots in Buddhist, Taoist, and folk traditions dating back to the Tang dynasty (618-907). According to Chinese folklore, the festival is a time when ghosts and spirits are free to wander the earth. During this time, the rituals are observed to try and avoid the wrath of wandering spirits.

This image was obtained with the wide-field view of the Mosaic Camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. vdB 141 is a reflection nebula located in the constellation Cepheus. Sometimes referred to as the ghost nebula, its awkward name is its catalog number in Sidney van den Bergh's catalog of reflection nebulae, published in 1966. Several stars are embedded in the nebula. Their light gives it a ghoulish brown color. North is down and East is to the right. 

The Nicholas U. Mayall Telescope is a four-meter (158 inches) reflector telescope in Arizona named after Nicholas U. Mayall. It saw first light on February 27, 1973, and was the second-largest telescope in the world at that time.

Aurora over Pennsylvania

Aurora over Pennsylvania

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.

Earth auroras have different names depending on the pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

Coma Cluster: Held Together by Dark Matter | Victor Blanco Telescope

Coma Cluster: Held Together by Dark Matter | Victor Blanco Telescope

The Dark Energy Camera captures an image of the dazzling Coma Cluster, named after the hair of Queen Berenice II of Egypt. Not only significant in Greek mythology, this collection of galaxies was also fundamental to the discovery of the existence of dark matter. The theory emerged in 1937 when Swiss astronomer Fritz Zwicky noticed that the Coma Cluster galaxies behaved as if they were under the influence of vast amounts of unobservable ‘dark’ matter.

The Dark Energy Camera on the Victor Blanco Telescope has probed the Coma Cluster—a rich cluster of galaxies named for the hair of an ancient queen and an inspiration for the theory of dark matter. This densely populated image showcases an enormous cluster not of individual stars, but of entire galaxies, known as the Coma Cluster. The Coma Cluster is named for the constellation where it lies, Coma Berenices. It is the only one of the 88 IAU constellations to be named after a historical figure. Its namesake is Queen Berenice II of Egypt, or more precisely her hair, with ‘coma’ meaning ‘hair of the head’ in Latin.

Distance: 320 million light years

Berenice famously cut her hair off and presented it as a votive offering to the gods when her husband returned safely from war. The hair was placed in a temple, but went missing soon after. The court astronomer, Conon of Samos, claimed to identify Berenice’s lost tresses in a rather unlikely spot—the night sky—suggesting that the goddess Aphrodites had catasterized (literally turned into a constellation) the queen’s locks. This all took place around 245 BCE, meaning that Berenice’s hair has enjoyed celestial recognition for an extraordinarily long time.

The data used to build this detailed picture were collected by the Department of Energy-fabricated Dark Energy Camera (DECam). It is mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of the National Science Foundation's NOIRLab. The 570-megapixel camera was built to carry out the Dark Energy Survey (DES)—an amazing 758-night run of observations between 2013 and 2019. DES was conducted with the intention to better understand the nature of dark energy—the unknown entity that is causing the expansion of our Universe to accelerate.

The Coma Cluster is closely associated with dark energy’s equally mysterious counterpart: dark matter. Nearly a century ago, in 1937, Swiss astronomer Fritz Zwicky observed several galaxies within the Coma Cluster. He calculated an approximation of the cluster’s mass based on its luminous—in other words, observable—structures.  However, he encountered something strange. The cluster seemed to be missing mass. In fact, the galaxies within the cluster were behaving as though the cluster contained 400 times more mass than his estimates suggested.

Zwicky reached this conclusion by observing how fast the galaxies within the cluster were moving. To explain this further, it is helpful to briefly revisit a key point about the nature of gravity. Gravity is one of the four known fundamental interactions that exist between all entities with energy or mass. The more mass that an object has, the stronger the gravitational pull it will exert. Therefore, less massive objects that are within a certain distance to a more massive object will be pulled uncontrollably towards it.

However, there is an additional factor to consider: velocity. If an object is moving fast enough, it can escape the gravitational pull of other objects. It is this principle that enabled Zwicky to infer that the Coma Cluster appeared to be ‘missing’ matter. He found that the galaxies were moving so fast that they should be escaping the cluster if it were being held together only by the observable mass. This led him to postulate that the cluster must be held together by vast amounts of unobservable ‘dark’ matter, although this suggestion seemed far-fetched to much of the astronomical community.

It took until the 1980s for the majority of astronomers to be convinced of the existence of dark matter. The consensus moved as several studies came out reporting the same curious mass inconsistency that Zwicky observed, but on the scale of single galaxies rather than entire galaxy clusters. One such study was done in 1970 by U.S. astronomers Kent Ford and Vera C. Rubin, who found evidence of invisible matter in the Andromeda Galaxy. And in 1979, astronomers Sandra Faber and John Gallagher performed a robust analysis of the mass-to-light ratio for over 50 spiral and elliptical galaxies. This led them to conclude that, “the case for invisible mass in the Universe is very strong and getting stronger.”

The existence of dark matter and dark energy is now widely accepted, and understanding their elusive nature is a main focus of modern astrophysics. A deeper understanding may be on the horizon with the upcoming 10-year Legacy Survey of Space and Time. It will be conducted by NSF–Department of Energy Vera C. Rubin Observatory, named after the inspirational female astronomer that helped show the world that there is so much more to the Universe than meets the eye.

The Eyes Galaxies: NGC 4438 & 4435 | NASA's Chandra X-ray Observatory

This composite image features a pair of merging galaxies, each resembling a brilliant white dot, earning the pair the nickname ‘The Eyes’. Near our lower left is the galaxy NGC 4438. This bright white dot is surrounded by a neon purple cloud of hot gas seen with Chandra. An inky black cloud nestled in a vertical strip of haze partially blocks our view of the neon purple, superheated gas. At our upper right is the second galaxy, NGC 4435. This bright white dot is surrounded by a thin, neon purple ring. The galaxy sits in the center of a glowing white streak, at the heart of a misty white pool. Flecks of white and neon purple speckle the image, set against the blackness of space.

This system contains a pair of merging galaxies in the Virgo Cluster and the multimillion-degree gas emits X-rays detected by NASA's Chandra x-ray observatory. In this image, x-rays from Chandra (purple) and optical light from the European Southern Observatory (red, green, blue) are visible.
