Where are large dust clouds predominantly located in the galaxy M51 view available hint S?
Where are large dust clouds predominantly located in the galaxy M51? As is generally true for spiral galaxies, large, star-forming dust clouds are located primarily within or on the edges of spiral arms.
Which type of galaxy typically contains the greatest amounts of dust?
ELLIPTICAL galaxies are slowly rotating ellipsoids, usually containing little gas and dust. IRREGULAR galaxies have no simple shape, and usually contain a lot of gas and dust.
Where are most of the bright stars in our Milky Way galaxy located?
The Galactic Center lies in the direction of Sagittarius, where the Milky Way is brightest.
Why are the ionization nebulae so bright?
Why are the ionization nebulae so bright? They are regions where gas is ionized by hot young stars. The gas in ionization nebulae is ionized by hot young stars. … A stands out in a photo of a galaxy because it shines brightly with light from massive young stars and glowing clouds of gas and dust.
Where are large dust clouds predominantly located in a spiral galaxy?
As is generally true for spiral galaxies, large, star-forming dust clouds are located primarily within or on the edges of spiral arms.
What is at the edge of the galaxy?
The Edge of the Galaxy was a star system located in the Braxant sector of the galaxy's Outer Rim Territories. By the year 4.3 ABY, it was home to a new and exotic resort that included the Rodon Value Pod Hotel, the Solar Power Plant, and the Space Observatory, as well as an asteroid installation.
Where in the galaxy is the dust seen?
A dust lane consists of a relatively dense, obscuring clouds of interstellar dust, observed as a dark swath against the background of a brighter object(s), especially a galaxy. These dust lanes can usually be seen in spiral galaxies, such as the Milky Way, when viewed from the edge.
What galaxies have dust?
Our galaxy is one of roughly 100 billion galaxies visible to us. Spiral galaxies have rotationally flattened disks, and contain moderate amounts of gas and dust. Elliptical galaxies are slowly rotating ellipsoids, and contain little gas and dust.
Where most of the dust and gas are located in the Milky Way?
the Galactic Bulge At the centre of the Milky Way is what's called the Galactic Bulge, a region densely packed with stars, dust and gas.
What is Hubble nebula?
The Hubble Space Telescope has captured a stunning view of the Prawn Nebula floating through deep space. The Prawn Nebula, formally known as IC 4628, is an emission nebula located 6,000 light-years from Earth, in the constellation Scorpius.
When was nebula discovered?
It wasn't until the 17th century and advances in optics that nebulae became more observed. In 1610, Nicolas-Claude Fabri de Pieresc discovered the Orion Nebula, which was then observed in 1618 by Johann Baptist Cysat. The first detailed observations, though, waited for famous scientist Christiaan Huygens in 1659.
What is in the center of a spiral galaxy?
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.
Where are dust and cold gas mostly found in elliptical galaxies?
Elliptical galaxies, such as M87 (left), have very little gas and dust. Because gas and dust are found in the clouds that are the birthplaces of stars, we should expect to see very few young stars in elliptical galaxies. In fact, elliptical galaxies contain primarily old, red stars (also known as Population II stars).
What is the largest known galaxy?
IC 1101 The biggest known galaxy, first described in a 1990 study from the journal Science (opens in new tab), is IC 1101, which stretches as wide as 4 million light-years across, according to NASA (opens in new tab). Galaxies are often bound to each other gravitationally in groups that are called galaxy clusters.
Where is the end of our galaxy?
This occurred at a distance of about 950,000 light-years from the Milky Way's center, marking the galaxy's edge, the scientists say. The edge is 35 times farther from the galactic center than the sun is.
What is the dust in the galaxy?
The dust in galaxies consists of small grains of carbon, silicon, iron, aluminium and other heavier elements. The Milky Way has a very high content of carbonaceous dust, which has been shown to be very rare in other galaxies.
Why is there dust in the galaxy?
The hot ultraviolet radiation heats the surrounding ice-cold dust, which then emits light in the far-infrared. He said: It is this far-infrared light, which tells us that there is dust in the galaxy. It is very surprising and it is the first time that dust has been found in such an early galaxy.
Where does dust in the galaxy come from?
Dust grains are formed in rapidly-cooling gas of stellar outflows (Draine and Salpeter, 1977; Yamamoto and Hasegawa, 1977). We call such grains 'stardust'. Sources of the stardust are asymptotic giant branch (AGB) stars, su-pernovae (SNe), red supergiants, novae, Wolf-Rayet stars, and so on (e.g., Gehrz, 1989).
What type of galaxy has the most dust and gas?
Type c spiral galaxies Type c spiral galaxies have the most gas and dust.
Which of the three parts of the Milky Way galaxy contains gas and dust?
The disk also the galaxy about contains atomic (HI) and molecular (H2) gas and dust. Here is an excellent tutorial on the Shape of the Milky Way by Rick Arendt.
What nebula is Earth in?
The closest known nebula to Earth is called the Helix Nebula.
How did the Orion Nebula form?
The discovery hints at the nebula's origins: radiation and explosions of massive stars at the ring's center may have blasted gas and dust outward until some of the material collapsed to give birth to the famous star creator.
Where are nebulae located?
interstellar space Where are nebulae? 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.
How do you draw a nebula?

Which of the galaxies show evidence of dust?
Spiral galaxies appear as flat, blue-white disks of stars, gas and dust with yellowish bulges in their centers. These galaxies are divided into two groups: normal spirals and barred spirals.
How much dust is in a spiral galaxy?
This leaves these galaxies dominated by their large bulges of old stars, and their disks relatively small containing faint, smooth, tightly wound arms. In contrast, Sc spirals contain about 15% gas and dust meaning that a relatively high proportion of the mass of the galaxy is involved in star formation.
What does M stand for in the Milky Way galaxy?
The Index Catalogue (IC) lists an additional 5,286 galaxies, nebulae, and star clusters discovered between 1888 and 1907. Names with the letter M are Messier objects, named after Charles Messier, a French astronomer.
What is the biggest thing in the world 2021?
The world's biggest thing to ever live and survive on the planet is the giant Antarctic blue whale.
How old is the Earth?
