Protostar (Pre-star) is a celestial body formed by the gravitational collapse of a dense core composed of gas and dust during the early stage of star formation, in which nuclear fusion reactions have not yet begun in its center.【1】 The structure at this stage has not yet transitioned into a stable energy production process through hydrogen nuclei converting into helium; however, temperature and density continue to increase. A protostar emits energy primarily through gravitational contraction and

The Trifid Nebula is a complex type of nebula located in the constellation Sagittarius in the sky, exhibiting both emission and reflection nebula characteristics. Also known as Messier 20 (M20), this structure is located approximately 5,000 light-years away and is about 40 light-years wide. The name "Trifid" comes from the dark dust lanes passing through the center of the nebula, dividing it into three main regions.Structure and TypeThe Trifid Nebula stands out for housing three different types

Andromeda Galaxy (M31) is the closest spiral galaxy to the Milky Way and is located approximately 2.5 million light-years away. As the farthest celestial object visible to the naked eye, Andromeda holds great importance for astronomers. Providing critical information about galaxy formation and evolution in the universe, Andromeda is at the center of many scientific studies.Discovery and HistoryObservations of the Andromeda Galaxy date back to ancient times. In 964, the Persian astronomer Abd al-

editTriangulum Galaxy (Messier 33 or NGC 598) is the third-largest galaxy in the Local Group after the Milky Way and Andromeda. It is generally accepted that the galaxy was first discovered in 1654 by Giovanni Battista Hodierna and was later cataloged by Charles Messier in the 18th century as M33. M33 is relatively easy to observe, making it a significant research target for both amateur and professional astronomers.General FeaturesLocation: Located in the Triangulum constellationDistance: Appro

Condor Galaxy (NGC 6872) is a barred spiral galaxy located in the southern sky in the constellation Pavo (the Peacock). It was first discovered on June 19, 1835, by English astronomer John Herschel. Also known as the Condor Galaxy, this galaxy has been the subject of astronomical research due to its unusually long spiral arms and its interacting structure.NGC 6872 has drawn particular attention because of its size. The spiral arms span up to 522,000 light-years from end to end. This length is ap

NGC 1569 is an irregular dwarf galaxy with high star formation activity, located in the nearby cosmic neighborhood of the Milky Way Galaxy. Situated approximately 11 million light-years (3.36 Mpc) away, this galaxy is observed in the constellation Camelopardalis. NGC 1569 stands out for its intense starburst phase that occurred within the last few hundred million years. In this regard, it serves as a critical example for observational and theoretical studies on the galactic-scale effects of star

NGC 3628 Galaxy is an unbarred spiral galaxy located in the constellation Leo, observed edge-on from Earth. Although this galaxy is often referred to in astronomical sources as the "Hamburger Galaxy," such nicknames are not used in academic contexts. NGC 3628 is a member of the galaxy group known as the "Leo Triplet", along with Messier 65 (M65) and Messier 66 (M66). This structure provides an important area of study, particularly for observing interactive galaxy dynamics and external gravitatio

NGC 4650A Galaxy is a galaxy located in the direction of the Cetus constellation and classified in astronomical literature as a "polar ring galaxy." First discovered in the mid-20th century, this galaxy attracts attention due to its ring structure, which is positioned at a right angle to the main body. NGC 4650A is one of the best-studied and exemplary celestial objects among polar ring galaxies.Structural FeaturesThe structure of NGC 4650A consists of two main components: a central elliptical o

NGC 6240 Galaxy is a pair of colliding galaxies located approximately 400 million light-years away in the direction of the Scorpius constellation. This galaxy pair consists of two large galaxies in the process of merging and stands out in observations due to its structural and dynamic characteristics. NGC 6240, in particular, serves as a critical example in research due to its high-energy radiation sources and complex gas dynamics.Structural and Dynamic PropertiesNGC 6240 is a system with two se

NGC 7318 A Galaxy is one of the prominent members of the galaxy group known as Stephan’s Quintet. This group is one of the regions of special interest for astronomers to study dynamic interactions between galaxies, and it is frequently observed in detail, particularly by NASA’s Hubble Space Telescope and James Webb Space Telescope. Due to its close proximity within the group, NGC 7318 A is in strong gravitational interaction with surrounding galaxies; this situation causes noticeable distortions
