The light spectrum coming from the planet. Each element has its own distinct color spectrum.
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.
Yes, nearby stars generally have larger parallax angles than distant stars. Parallax is the apparent shift in the position of a star when observed from different points in Earth's orbit around the Sun. The closer a star is to Earth, the greater the angle of this shift, making it easier to measure compared to more distant stars, which exhibit much smaller angles due to their greater distances.
to see a distant objects..like stars..
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.
Changes in the light from distant stars and galaxies can be caused by several factors, including intrinsic variations in the stars themselves, such as pulsations or eruptions, which can alter their brightness. Additionally, gravitational lensing can bend and magnify light from distant objects due to the presence of massive foreground objects. Cosmic events like supernovae also lead to dramatic changes in brightness. Lastly, the redshift effect, caused by the expansion of the universe, can alter the observed wavelength of light from distant galaxies.
Distant Stars was created in 1981.
Distant Stars has 352 pages.
still looking for answers i dont know..
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.
Distant stars give off less light
Stars are distant suns, which are roughly spherical in shape.
they are made of helium and hydrogen scientists know this becuz of a spectrometer
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.

Well it depends on what you mean. The distance for how long it takes, or the time as in how long since Earth was made. Earth as you know has been here a long long time. Stars light has been shinning towards Earth eversince it was made. To see how long it takes for a stars light to reach Earth depends on how distant and huge the star is.
