The amount of the Doppler shift tells us how fast the star is moving relative to us. In addition, the direction of the Doppler shift can tell us the direction of the star's movement. If the spectrum of a star is shifted to the blue end, the star is moving toward us; if the ...
Astrophysicists have been in a race to measure precisely how fast the Universe is expanding since Hubble announced that galaxies were systematically moving away from Milky Way Galaxy with a current speed in 1929. Hubble's observations came after Einstein's general relativity, which inspired the big...
In 1924, the astronomer A. S. Eddington showed that the luminosity and mass of a star were related. The larger a star (i.e., more massive) is, the more luminous it is(luminosity = mass3). Stars around us are moving with respect to oursolar system. Some are moving away from us an...
The plane of the Milky Way stretches across the sky into northern constellations as well. This is not the core of the Milky Way galaxy, but it is still a noticeably dense region of stars that creates a faint band of light from a dark sky. The photo below shows the Cygnus region of th...

But if the source is moving away from us, we see these lines shifted towards the red end of the spectrum — hence the term "redshift". Measuring the amount of this shift gives a good indication of how fast the object is traveling away from us. Hubble’s great discovery, in 1929, ...
How fast is a light year? The Speed of Light: The speed of light is approximately 186,000 miles per second, or approximately 300,000 kilometers per second. It is the fastest that anything in the universe can travel. Answer and Explanation:1 ...

How fast do rogue planets move?Rogue planets:Rogue planets are a term used to describe a planet that has been ejected from its solar system and is now orbiting the Sun alone. Rogue planets can be seen as objects of curiosity, but they also pose certain threats to Earth. Some astronomers ...
