Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
What are not a reason that astronomers have trouble viewing distant start?
Astronomers do not have trouble viewing distant stars due to their brightness, as many distant stars are incredibly luminous. Instead, challenges arise from factors like cosmic dust obscuring light, the expansion of the universe redshifting light from distant objects, and limitations of current telescope technology. Additionally, atmospheric interference can hinder ground-based observations, but these issues are not related to the inherent brightness of the stars themselves.
What is best way to study young stars hidden behind interstellar dust clouds?
One effective way to study young stars hidden behind interstellar dust clouds is by using infrared telescopes. Infrared light can penetrate dust clouds more easily than visible light, allowing astronomers to observe these young stars more clearly. Additionally, combining data from multiple telescopes and techniques, such as radio astronomy, can provide a more complete picture of these hidden stars.
Why does the milky way look like a hazy band of stars in the sky?
The Milky Way appears as a hazy band of stars in the sky because we are viewing it edge-on from within the galaxy. The combined light of billions of distant stars, interstellar gas, and dust within the plane of the galaxy creates this band of light across the night sky.
How can you measure the time using the stars?
light years
Why are distant stars redder than nearby stars of the same spectral type?
Distant stars appear redder because of interstellar dust and gas that scatters and absorbs light, causing longer wavelengths (redder colors) to be more prominent. This effect, known as reddening, is more pronounced for light from distant stars due to the increased path length through interstellar medium.
Interstellar reddening is caused by what?
A downward shift in frequency of radiation (perceived as reddening in the visible spectrum) is observed in most stars outside the Milky Way Galaxy. This red shift is assumed to be caused by the stars moving away from our galaxy at a sizable fraction of the speed of light. This shift is similar to the Doppler effect in sound.
What cause changes in the light coming from distant stars and galaxies?
The apparent redshift is caused by the Doppler Effect; the frequency of waves is increased by an approaching source and decreased by a leaving source. Since the fgrequencies we see from stars are slightly lower than they should be, we know that the stars and other objects are moving away. The Doppler Effect causes changes of light emanating from distant stars and galaxies.
What is the center of a distant nebulas?
Massive stars are the center of a distant nebula. The massive stars are formed as the gas in the interstellar medium collapses under its own weight. The size of a nebula depends on the size of the original gas cloud.
Which of the following is not a reason that astronomers have trouble viewing distant stars?
Distant stars give off less light
Do we see stars in the sky because they reflect the sun's light?
No. The stars are distant suns that emit their own light.
What is good about darkness?
Darkness allows us to better see the stars and nebula, supernova remnants, interstellar clouds of hydrogen, star clusters and distant galaxies. Dark skies. Light pollution robs our children of their birthright--the enjoyment of the heavens.
Are Stars cold and make light?
Stars make their own light, but they are not cold. Stars are extremely hot. We do not feel their heat because they are incredibly distant.
What is he meaning of interstellar?
Between or among the stars; as, interstellar space.
what is the meaning of Interstellar?
Between or among the stars; as, interstellar space.
What do telescopes do in order for us to see distant stars?
it collects light
Reasons why astronomers have difficulty looking at distant stars except?
Light years of dust lanes obscure the view of distant stars in visible light. However, radio telescopes can penetrate the dust and can detect (in the x-ray and infrared spectra) the stars in the core of our galaxy.They don't understand how redshift affects stars.
