The Jellyfish Galaxy, also known as ESO 137-001, is a visually striking galaxy located in the constellation Hydra. It is particularly notable for its distinctive tail of gas and stars, which appears to flow behind it like the tentacles of a jellyfish—hence its nickname. This unusual feature is believed to be the result of the galaxy moving through the hot gas of the Fornax Cluster, which strips away gas and dust from the galaxy's outer regions.

The Kennicutt–Schmidt law, formulated by B. D. Kennicutt in the early 1990s, describes the empirical relationship between the surface density of star formation and the surface density of gas in galaxies. This law is significant in astrophysics as it provides insight into how stars form and evolve across different types of galaxies.

LAE J095950.99+021219.1 is a distant astronomical object, specifically a Lyman Alpha Emitting (LAE) galaxy. It was identified in a survey of the sky and is notable for its redshift, indicating that it is situated at a significant distance from Earth. This means that it is being observed as it was in the early universe.

Leo P is a musician and beatboxer known for his unique style that combines beatboxing with live looping and instrumentation. He gained popularity through social media platforms like TikTok and YouTube, where he showcases his talent by layering vocal percussion, harmonies, and various instruments to create engaging music. Leo P has built a strong following thanks to his creativity and ability to perform complex arrangements using just his voice and looping technology.

A list of galaxies typically refers to a compilation of different galaxies observed in the universe, categorized by various criteria such as their type, size, distance from Earth, or other astronomical features. Here are some well-known types of galaxies along with examples: ### Types of Galaxies: 1. **Spiral Galaxies**: Characterized by their spiral arms.

Globular clusters are dense spherical collections of stars that orbit galaxies. Some galaxies are known for having particularly rich globular cluster systems, characterized by a high number of globular clusters. Here’s a list of some galaxies known for their rich globular cluster systems: 1. **Milky Way Galaxy** - Our own galaxy has about 150 known globular clusters, making it one of the richest in terms of cluster count.

The largest galaxies in the universe can be ranked based on various criteria, such as their mass, diameter, or the number of stars they contain. Here are some of the largest known galaxies based on these criteria: 1. **IC 1101**: Often considered the largest galaxy currently known, IC 1101 is a giant elliptical galaxy located in the Abell 2029 galaxy cluster.

Lists of galaxies are compilations of galaxies categorized and organized based on various criteria such as their type, location in the sky, or other characteristics. These lists can include well-known galaxies, like the Milky Way and Andromeda, as well as more obscure ones. Here are a few common ways galaxies are organized in lists: 1. **By Type**: Galaxies can be classified into types based on their shape and structure, such as: - Spiral galaxies (e.g.

"Local Volume" can refer to different concepts in various fields, so its meaning can depend on the context in which it is used. Here are a few interpretations: 1. **In Astronomy**: Local Volume can refer to a region of space surrounding the Milky Way galaxy that includes nearby galaxies.

In astronomy, the luminosity function is a statistical distribution that describes the number of stars (or other celestial objects) per unit volume as a function of their luminosity. It provides an important tool for understanding the population of stars in a given region of space and how these stars are distributed in terms of their brightness and energy output. The luminosity function is often expressed as \( \phi(L) \), which represents the density of stars with a given luminosity \( L \).

A Lyman-alpha emitter (LAE) is a type of astronomical object, typically a galaxy, that exhibits strong emission of Lyman-alpha radiation. The Lyman-alpha line corresponds to a specific wavelength of ultraviolet light (121.6 nanometers) emitted by hydrogen atoms when an electron transitions from the second lowest energy level (n=2) to the ground state (n=1). Lyman-alpha emitters are of particular interest in studies of the early universe.

A Lyman-break galaxy (LBG) is a class of distant galaxy observed in the early universe, typically characterized by a significant drop in ultraviolet (UV) light at wavelengths shorter than the Lyman limit (approximately 121.6 nanometers). This Lyman limit corresponds to the transition of hydrogen atoms from their ground state to a higher energy state.

MACS0647-JD is a distant galaxy that has garnered significant interest in the field of astronomy due to its extreme distance from Earth. It was discovered as part of a survey of galaxy clusters using the Hubble Space Telescope and other instruments. The galaxy is located approximately 13.3 billion light-years away, which means we see it as it was shortly after the Big Bang.

MACS J1423.8+2404 (often abbreviated to MACS 1423-z7p64) is a distant galaxy cluster located in the constellation of Virgo. It is particularly interesting to astronomers because it contains a significant number of very distant galaxies, which can provide insights into the early universe. The cluster is notable for the discovery of some of the most distant and faint galaxies ever observed, helping researchers study the formation and evolution of galaxies in the early cosmos.

MACS J2129-0741, often referred to as MACS 2129-1, is a galaxy cluster that is notable for its significant mass and has been studied extensively in astrophysics. It is located in the constellation of Aquarius and is noteworthy for being one of the most massive galaxy clusters known.

The M–σ relation, also known as the "mass–sigma relation," describes a correlation between the mass of a supermassive black hole (SMBH) at the center of a galaxy and the velocity dispersion (σ) of stars in that galaxy's bulge.

NGC 5501 is a spiral galaxy located in the constellation Ursa Major. It is part of a larger group known as the NGC 5500 group of galaxies. NGC 5501 is characterized by its bright nucleus and well-defined spiral structure, which makes it a subject of interest for astronomers studying galaxy formation and evolution. This galaxy is roughly 70 million light-years away from Earth and has a diameter of about 100,000 light-years.

NGC 7041B is a galaxy located in the constellation of Grus. It is part of a group of galaxies and is often studied in the context of its morphology and characteristics. NGC 7041B is noted for being a part of a larger system known as NGC 7041, which includes other galaxies. Observations may reveal details about its structure, star formation activity, and interactions with neighboring galaxies.
