Trifid Nebula accompanied by a reflection nebula: M20

Yu-Chi Huang

Taiwan

Collections:National Museum of Natural Science

Dimensions: 3648*2736

 

Backstory

The M20 is one of the most beautiful emission nebulae in the Milky Way Galaxy in the summer. Besides the clearly observable red cloud (interstellar dust emits different colors depending on the composition: red is Hydrogen alpha, Nitrogen 2, and Sulphur 2 and light blue is Oxygen 3 and Hydrogen-beta), the M20 also exhibits a light-blue background known as a reflection nebula. With the reflection nebula, the M20 presents richer colors, making it stand out from its brothers and sisters in the Milky Way Galaxy.




 

Markarian’s Chain


Kuan-Wei Huang

Collections:National Museum of Natural Science

Dimensions: 3648*2736

 

Backstory

The most prominent night view in spring is the slow ascension of the Virgo Cluster. The Markarian’s Chain is an arc-shaped series of galaxies roughly in the center of the cluster. The galaxy at the bottom left of the chain is the massive and elliptical galaxy,  M87. The image was taken with an 800 mm prime lens. It is only a corner of the galaxy cluster.


 

M81‧M82: Bode’s Galaxy and Cigar Galaxy

Collections:National Museum of Natural Science

Dimensions: 3648*2736

 

Backstory

Bode’s Galaxy (M81) is on the left, and Cigar Galaxy (M82) is on the right. Both galaxies are located in Ursa Major, which is the galaxy cluster to the Local Group. The seemingly silky shape of the two galaxies stems from their strong gravitational interaction with the NGC3077 galaxy, stripping hydrogen gas away from all three galaxies. A type Ia supernova was newly observed in M82. This close proximity of this supernova from earth is extremely rare.



Filial Piety in the Star Cluster Family (II)

Yu-Chen Lin

Taiwan

Collections:National Museum of Natural Science

Dimensions: 3648*2736

 

Backstory

The universe comprises a myriad of star clusters, which can be broadly characterized into globular clusters and open clusters. However, the fate and mass of these clusters differ greatly. Globular clusters, such as the M13, are extremely bulky and usually sit far away from the Milky Way. Some are even more ancient than the Milky Way itself. Open clusters, such as the NGC2237, mostly sit on the galactic disk. They are one of the main birthplaces of stars. Nonetheless, beautiful nebulae can be seen nearby, such as the emission nebulae NGC2237 (interstellar dust emits different colors depending on the composition: red is Hydrogen alpha, Nitrogen 2, and Sulphur 2 and light blue is Oxygen 3 and Hydrogen-beta).

Dumbbell Nebula M27 (II)

Chieh-Cheng Yu

Taiwan

Collections:National Museum of Natural Science

Dimensions: 2586*1723

 

Backstory

Highlighted by the surrounding blackness, the solitary Dumbbell Nebula M27 is one of the most beautiful nebulae in the summer sky. The Dumbbell Nebula is a planetary nebula. It is slightly darker in the night sky, making it slightly more difficult to observe. However, the surrounding planetary nebulae are darker or smaller than the Dumbbell Nebula, making it the first planetary nebula to be discovered. Its central start is also the largest known white dwarf. The M27 looks like a cute dumbbell, thus deriving its name.

Orion Nebula M42

Che-Hao Chang

Taiwan

Collections:National Museum of Natural Science

Dimensions: 4104*2736

 

Backstory

In the past, one could only see a blurry image of the Orion Nebula in an infinitely vast sky. Now, clear images have finally been taken for us to examine its secrets. The Orion Nebula M42 is a fuzzy nebula just below Orion’s Belt and it looks similar to the legendary phoenix rising from the ashes in all its beauty. It’s an extremely bright nebula. Therefore, it is also known as the King’s Lantern. It can even be seen with the naked eye in environments with light pollution.



Nebula

Han-Tao Li

China, Hubei

Collections:National Museum of Natural Science

Dimensions: 1920*1440

 

Backstory

Andromeda Galaxy (M31): the Milky Way Galaxy and the Andromeda Galaxy are on a collision course. In roughly three billion years, the two galaxies will collide, creating a massive oval galaxy. The M31 and the Milky Way Galaxy are fairly similar. Therefore, comparing the two galaxies can reveal clues to the dynamics, structure, and evolution of the Milky Way Galaxy. Looking up at the Andromeda Galaxy from earth is an incredible experience. It is like a speck of sand trying to observe the entire desert. The distance has made us realize just how massive the universe really is.



Whirling Aurora (I)

http://www.mygoods.com.tw/ReadImg?p=Result&id=52960&site=5

Yi-Te Lai

Finland

Collections:National Museum of Natural Science

Dimensions: 7047*3045

 

Backstory

When solar winds carry charged particles near to earth, a portion of these particles is attracted to the north and south poles because of earth’s magnetic field. These particles collide with earth’s atmosphere, producing light known as auroras. The green color largely seen in auroras is the emissions discharged by oxygen molecules when they collide with the charged particles. Sometimes, auroras can be blue or red (or a mixture of the two colors creating purple). These colors are the emissions discharged by nitrogen molecules when they collide with the charged particles. Solar activity peaked in 2013, creating arc-shaped and curtained auroras in the night sky in mid-March. Whirling aurora was even seen dancing in the sky.



Whirling Aurora (II)

Mirage in the Winter Night – Light Pillar

http://www.mygoods.com.tw/ReadImg?p=Result&id=52944&site=5

Yi-Te Lai

Taiwan

Collections:National Museum of Natural Science

Dimensions: 5121*3211

 

Backstory

Light pillars are an atmospheric optical phenomenon. The effect is created by the reflection of light from numerous tiny ice crystals suspended almost parallel to the ground. When ice crystals are present in the atmosphere, they may reflect the light of the sun below the horizon to create a solar pillar. However, in the cold winter nights of northern countries, light pillars are formed by the ice crystals reflecting terrestrial light. This phenomenon requires low temperatures without snow so that ice crystals can form in the air. Therefore, its occurrence is relatively rare. Compared to the cold moonlight, light pillars created by city lights are significantly more colorful.
