What does the Omega Nebula look like?

The Omega Nebula – aka M17 – is barely visible to the unaided eye on a dark, moonless night. To see it, it's best to use binoculars or low-power magnification on a telescope. The Omega Nebula is very near another prominent nebula, known as M16 or the Eagle Nebula.

What color is the Omega Nebula?

The Omega Nebula's reddish colour is the result of hot hydrogen gas being illuminated by newly formed stars in the nebula.

How was the Omega Nebula formed?

M17 (Also called the Swan Nebula) is an H II region (emission nebula) that lies between 5000-6000 light-years from Earth. The Omega Nebula is a star factory sculpted by stellar winds and radiation. The cavernous appearance of this emission nebula was carved out by energetic light from hot, massive stars.

Is the Omega Nebula in our galaxy?

Illuminated by ultraviolet radiation from young, massive stars on the right side of this photograph, M17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy.

How did the Omega Nebula get its name?

Herschel give Omega its name

The English mathematician and astronomer, John Herschel was the first to identify the shape of the Nebula as that of the Greek letter, Omega. In his 1833 research, Herschel explained the shape of the arms of dust, gas, and debris was similar to the Greek capital letter.

What is a Messier object in space?

The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his Catalogue des Nébuleuses et des Amas d'Étoiles (Catalogue of Nebulae and Star Clusters).

How many nebulae are there?

There are believed to be about 20,000 objects called planetary nebulae in the Milky Way Galaxy, each representing gas expelled relatively recently from a central star very late in its evolution. Because of the obscuration of dust in the Galaxy, only about 1,800 planetary nebulae have been cataloged.

Why is it called Swan Nebula?

One of the brightest and most massive star-forming regions in our galaxy, the Omega or Swan Nebula, came to resemble the shape resembling a swan's neck we see today only relatively recently.

What comes after planetary nebula?

Over time, the material from the planetary nebula is scattered into space. Eventually it will form part of the clouds of dust and gas where new stars form.

What cluster is Omega?

Omega Centauri, the largest globular star cluster of the Milky Way, contains about 10 million stars. This behemoth, with a diameter of 230 light-years, is 10 times more massive than a typical globular cluster.

What cluster is Omega in me3?

Omega is a mission location in the N7 HQ Galaxy at War mini-game for Mass Effect 3.

Can you return to Omega me3?

Upon completing the Omega DLC there is actually no way back, plus those side quests are completed during the missions.

Which nebula is the closest to Earth?

Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a dying star—possibly one like the Sun. It is approximately 700 light-years away from Earth.

What type of object is M24?

M24 is unique among Messier objects, which are mostly single, well-defined deep sky objects – star clusters, nebulae and galaxies – while the star cloud is not really a deep sky object but a collection of millions of stars found along the plane of the Milky Way and seen through a gap in the galaxy's dust lanes.

What is the closest Messier object to Earth?

One of these objects is known as Messier 34, an open star cluster located in the northern Perseus constellation. Located at a distance of about 1,500 light years from Earth, it is one of the closest Messier objects to Earth, and is home to an estimated 400 stars.

Are galaxies close together?

Galaxies are held together by mutual gravity and orbit around a common center. Interactions between galaxies is quite common, especially between giant and satellite galaxies.

What are stars in space?

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.

What is the power source of the typical emission nebula?

An emission nebula is a nebula formed of ionized gases that emit light of various wavelengths. The most common source of ionization is high-energy ultraviolet photons emitted from a nearby hot star.

What type of nebula is Messier 17?

Messier 17 (M17), also known as the Omega Nebula, is a famous star-forming nebula located in the southern constellation Sagittarius. The diffuse emission nebula lies near the constellation's northern border with Scutum, at a distance of 5,000 to 6,000 light years from Earth. It has an apparent magnitude of 6.0.

Is Boomerang Nebula a planet?

The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase. It continues to form and develop due to the outflow of gas from its core where a star in its late stage life sheds mass and emits starlight illuminating dust in the nebula.
