What else can I help you with?
Why are thre so many dwarf stars - red and white - among the nearest stars but none among the brightest stars?
Because dwarf stars aren't very bright. They are too SMALL to be especially bright, for one thing.
You and a friend are looking at the stars and you notice two stars close together one bright and the other fairly dim your friend comments that the bright star must emit much more light?
You and a friend are looking at the star and you notice two stars close together one bright and the other fairly dim your friend comments that the bright star must emit much more light. This might not be true because the other star could just be farther away or smaller.
What is a gigantism?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
What types of numbers are used to represent the magnitudes of very bright stars?
The magnitudes of very bright stars are represented using the apparent magnitude scale, which is a logarithmic scale. In this system, lower numerical values indicate brighter stars, with some of the brightest stars having negative magnitudes. For example, a star with a magnitude of -1 is brighter than one with a magnitude of +1. This scale allows astronomers to compare the brightness of celestial objects effectively.
In astronomy when said stars are close together as in constellations how far in light years are they distanced from one another?
Could be any distance. Generally, however, the bright stars that are part of constellations are within a few hundred light years of Earth.
What is a red gigant?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
How bright is a spiral galaxy?
the spiral galaxy is very bright because of its stars, that's why our galaxy is called the milky way because it looks milky and our galaxy(the milky way) is located in one of the arms of a spiral galaxy!
Are some background galaxies masked out due to being close to a bright foreground galaxy?
Yes, if two stars are along the same line of sight from our perspective, the closer one prevents us from seeing the farther one.
Is Vega the brightest star?
No. Apart from the sun, the brightest star as we see it is Sirius. Of course, as stars are different sizes and distances, there are stars that are brighter than it, but look dimmer because they are much further away. Sirius is one of the nearest stars to us, which is why it looks so bright to us. Vega is very bright looking to us, but much further away than Sirius.
How bright is Gemini compared to the sun?
Gemini, one of the brightest of the constellations, is about 882 times dimmer than the Sun. It contains several bright stars, with the two brightest stars being Castor and Pollux. Despite being bright in the night sky, Gemini is not as bright as the Sun.
Why do people close one eye in bright sunlight?
People close one eye in bright sunlight to reduce the amount of light entering their eyes and to improve their vision in the bright conditions. This helps to protect the eye from damage and discomfort caused by excessive light exposure.
What is a close nebula to Orion's nebula?
A nebula is a cloud of dust and gas in space. Some of the clouds block out the light from the stars behind. These are called dark nebulae. One of the best-known is the Horsehead Nebula. Other dust clouds reflect the light from the stars and shine brightly. These are called bright nebulae. : Edit: The Great Orion Nebula is M42. M43 is a close nebula close to M42.
