National Institute of Astronomical Research (Public body) (Public body) published through the page NAIT National Institute of Astronomical Research to celebrate “Halloween” Astronomer Style Pack of 5 deep space objects that look like horror. (But it’s still beautiful) Compiled by Thanakorn Angwattana – Astronomical Information Officer, Ror., As follows:
5 deep space objects that look like horror
1. Photo “Ghost Nebula”. o IC 63
from the Hubble Space Telescope It is both a reflecting nebula and an emitting nebula in the constellation of Cassiopeia, about 550 light years from Earth. The red emission region is formed by hydrogen gas which absorbs ultraviolet from the blue giant Gamma Cassiopeiae. inside the nebula and then released a red light The blue part is due to the reflection of the dust group. Formed as the appearance of a cloud of gas and dust like a veil. or disturbing spirits, making IC 63 known as “The Demon of Cassiopeia”

2. Photograph of the Witch’s Head Nebula or IC2118
It is a reflecting nebula located in the constellation of Orion, about 900 light years from Earth. Rather, it is caused by the light from nearby stars hitting these dust and gases. Then reflections and scattering of light occur. Where blue light is the light that disperses best. (The same principle applies when the sky on Earth is blue during the day.) This type of nebula is often blue. And for this nebula which is shaped like a face with a long chin and a curved nose. It looks like the face of a witch in the cartoon. hence the origin of the name “Witch’s Head Nebula”
Photo of the Ghost Head Nebula or NGC 2080
from the Hubble Space Telescope It is a dense cloud of dust and gas inside the Large Magellanic Cloud, about 160,000 light years from Earth.
These clusters of dust and gas are dispersed in space for over 50 light years. In the center of the image are two clusters of luminous gas, a region of very high intensity. Due to the high-energy radiation of the giant star hidden inside. It has become a look that invites the imagination of someone’s face. smiling in dark space is the origin of the name “The Phantom Head Nebula”
4. Photograph of the Jack-o’-lantern Nebula
from the Spitzer Space Telescope in the infrared range An image of a cloud of gas and dust that looks like a jack-o-lantern pumpkin has been revealed. Formed by stars that are 15-20 times more massive than the Sun inside. emit high-energy radiation It causes clouds of dust and gas to explode until they split into cavities that have the shape shown in the illustration.
This image is created from photographic data in the infrared region of 3 wavelengths. be processed in this multicolored image. Green and red represent dust clouds with different temperatures. Blue represents the emerging stars and hot dust clouds within the nebula. When the three images are put together The red color of the powder is the most noticeable. The white area represents the luminous spatial object in all three wavelengths.
Photo of the Tarantula Nebula or 30 Dorarus
fromJames Webb Space Telescope in the infrared region It is a huge cloud of dust and gas in space. and is the birthplace of tens of thousands of stars. It is located inside the Large Magellanic Cloud. At the center of the nebula is a newly formed star cluster with a combined mass of about 500,000 solar masses. and release tremendous energy A cloud of dust and gas spreads across a tangled filament surrounding the central cavities. Similar to a tarantula spider’s nest. is the origin of the name “The Tarantula Nebula” there
Astronomers are particularly interested in this nebula. Due to the chemical composition which is close to the composition of the universe. In an age when the universe is only a few billion years old (Currently, the universe is about 13.8 billion years old.) Studying the formation of stars in this nebula will help to understand the universe’s past and the first star formation.
