1. Explain Why We See The Milky Way As A Faint Band Of Light Stretching Across The Sky? (Solution)

The Milky Way appears as a faint band of light stretching across the sky because of the gas and dust that is present between the stars. The light from stars is absorbed by this interstellar dust. Thus, a faint band of light is seen.

  • When we observe the Milky Way at night from Earth, we see it as a faint swath of light stretching across the sky. Actually, that’s why it’s called the Milky Way. To begin with, the reason for its appearance is because of the amount of gas and dust contained within the Milky Way.

Why do we see the Milky Way as a band of light in the night sky rather than as a disk or Halo?

Why do we see the Milky Way as a band of light across the night sky? The Milky Way is a thin plane of the Galactic disk, seen from within. When out line of sight lies in the plane of the galaxy, we see many stars blurring into a continuous band. In other directions, we see darkness.

Why does the Milky Way star formation occur primarily in its thin disk Why is there very little star formation in the halo?

Why does star formation occur primarily in the disk of the Galaxy? The density waves in the disk form the gas and dust to form the star. The center of the galaxy is too dense and there is not a lot of gas and dust present to form a star.

Why do the stars of the galaxy appear to form a bright band that extends around the sky?

Terms in this set (28) Why do the stars of the galaxy appear to form a bright band that extends throughout the sky? Because Earth lies within the plane of the galaxy, so we’re only able to see towards the “edges” of the galaxy and the arm we lie in.

Can we see most of the Milky Way with visible light?

We can see most of the Milky Way with visible light. Observing our galaxy at radio wavelengths allows us to see through the dust in the disk that obscures our view. Most of the mass of the Milky Way is located in the halo of the galaxy in the form of dark matter.

Why do we see the Milky Way as a band?

From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe.

Why do we see the Milky Way as a band of light across the sky quizlet?

The Milky Way appears as a faint band of light stretching across the sky because of the gas and dust that is present between the stars. The light from stars is absorbed by this interstellar dust.

Where does star formation occur in the Milky Way?

Star formation occurs most rapidly in the spiral arms, where the density of interstellar matter is highest. The Galaxy captured (and still is capturing) additional stars and globular clusters from small galaxies that ventured too close to the Milky Way.

Where does most star formation occur in the Milky Way galaxy at present Group of answer choices?

10) Most of the current star formation in the Milky Way occurs in spiral arms.

Where does most star formation occur in the Milky Way today quizlet?

Where does most star formation occur in the Milky Way galaxy today? In the spiral arms.

What features of the Milky Way’s appearance in our sky led scientists to conclude that its width is much larger than its thickness?

What features of the Milky Way’s appearance in our sky led scientists to conclude that it is much wider than it is thick? The Milky way is the narrow band made of many resolvable stars. Why did they scientists originally believe that the Sun was near the Milky Way’s center?

How did Herschel map the Milky Way?

Abstract: In 1785 astronomer William Herschel mapped out the shape of the Milky Way star system using measurements he called “star-‐gages.” Herschel’s star-‐gage method is described in detail, with particular attention given to the assumptions on which the method is based.

What surrounds the Milky Way?

The Milky Way galaxy is in the recycling business. Our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars, according to a NASA-funded study in the journal Nature Astronomy.

Why is Milky Way not visible?

The core of the milky way is only visible about half of the year. The other half it is located beneath the horizon. In the winter months (December – February) it is not visible at all because it’s too close to the sun. In the spring (March – May), it will first become visible a few hours before sunrise.

Why can’t you see the Milky Way?

A new study finds that one third of humanity cannot see the Milky Way because of artificial light pollution. If you look up on a pitch black, cloudless night, you might be able to see the rest of our galaxy, the Milky Way, stretching across the sky.

Can we see out of the Milky Way?

The answer is no – unless you count seeing the combined light of many billions of stars. From the Northern Hemisphere, the only galaxy outside our Milky Way that’s easily visible to the eye is the great galaxy in the constellation Andromeda, also known as M31. This is the edgewise view into our own Milky Way galaxy.
