What classification is the Whirlpool Galaxy?

What classification is the Whirlpool Galaxy?

The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy.

What type of galaxy is the Whirlpool Galaxy and companion galaxy?

The Whirlpool’s most striking feature is its two curving arms, a hallmark of so-called grand-design spiral galaxies. Many spiral galaxies possess numerous, loosely shaped arms which make their spiral structure less pronounced. These arms serve an important purpose in spiral galaxies.

Is Whirlpool Galaxy two galaxies?

The most stunning features of the Whirlpool galaxy – officially known as M51a – are the two long, star-filled “arms” curling around the galactic center like ribbons. The much smaller M51b clings like a barnacle to the edge of the Whirlpool. Collectively known as M51, the two galaxies are merging.

Is the Whirlpool Galaxy in the Milky Way?

The Whirlpool (also known as Messier 51 (M51) is a two-armed spiral galaxy that lies somewhere between 25 to 37 million light-years away from our own Milky Way.

What is a Type 1 galaxy?

The nuclear spectra of Type 1 Seyfert galaxies show broad emission lines, which are indicative of a central concentration of hot gas that is expanding at speeds of up to thousands of kilometres per second. Type 2 Seyferts have strong emission lines, but they indicate more-modest velocities, less than…

What is an E type galaxy?

Type E galaxies are normal ellipticals with no structural details. From left to right the galaxies shown are NGC 1379, 3193, 5322, 1426, and 720. Type E+ galaxies are “late” ellipticals, which may include faint extended envelopes typical of large cluster ellipticals, or simple transition types to S0-.

Why is it called Whirlpool Galaxy?

The galaxy is nicknamed the Whirlpool because of its swirling structure. The Whirlpool’s most striking feature is its two curving arms, a hallmark of so-called grand-design spiral galaxies. Many spiral galaxies possess numerous, loosely shaped arms that make their spiral structure less pronounced.

What galaxy is Marvel in?

Is the Marvel Cinematic Universe a misnomer? As of now, the MCU only spans the Milky Way Galaxy (where we live) and the Andromeda Galaxy, our closest neighbor in space.

What are the 4 types galaxies?

The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.

Can a galaxy have 2 black holes?

Some galaxies, such as the galaxy 4C +37.11, appear to have two supermassive black holes at their centers, forming a binary system. If they collided, the event would create strong gravitational waves. Binary supermassive black holes are believed to be a common consequence of galactic mergers.

What are the 3 types galaxies?

What Kinds of Galaxies Are There? Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.

What galaxy is the Milky Way’s twin?

One of the highlights of the autumn sky is M31, the Andromeda Galaxy. It’s the most distant object that’s readily visible to the unaided eye — about two-and-a-half million light-years away. M31 and our own galaxy, the Milky Way, are near twins.

Does the Whirlpool Galaxy have a black hole?

The Whirlpool has a supermassive black hole at its heart, thanks to the merging of M51 with its neighboring galaxy, NGC 5195. The Whirlpool Galaxy’s fascinating structure gives astronomers a better understanding of how galaxies interact with each other and how stars form within them.

Is the Whirlpool Galaxy bigger than the sun?

Astronomers estimate that it is about 400 million years old and has a mass 40 million times larger than our Sun. The concentration of stars is about 5,000 times higher than in our solar neighborhood, the Milky Way Galaxy.

What type of galaxy is the Draco Dwarf?

The Draco Dwarf is a spheroidal galaxy which was discovered by Albert George Wilson of Lowell Observatory in 1954 on photographic plates of the National Geographic Society’s Palomar Observatory Sky Survey (POSS). It is part of the Local Group and a satellite galaxy of the Milky Way galaxy.

What is a blazar galaxy?

Blazars, a type of galaxy powered by a ginormous black hole and among the brightest, most energetic objects in the sky, are not unfamiliar to science. Many thousands of them have been identified.

What is a galaxy Grade 4?

A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you’re seeing other stars in the Milky Way.

What are the major classifications of galaxies?

Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.

How are the spiral galaxies classified?

Spiral galaxies are classified as Sa/SBa, Sb/SBb or Sc/SBc (classic/barred) according to the tightness of their spiral, the clumpiness of their spiral arms, and the size of their central bulge. These differences can be traced back to the relative amounts of gas and dust contained within the galaxies.

What property of a galaxy is used for classification?

We suggest that these three properties: mass, star formation and interactions/mergers are the major features that determine a galaxy’s physical state, and should be used to classify galaxies.

How do you categorize galaxies?

Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, ellipticals and irregulars. He classified spiral and barred spiral galaxies further according to the size of their central bulge and the texture of their arms.
