Astronomers refer to a galaxy with a jumbled scattering of stars as an "irregular galaxy." These galaxies lack a defined shape or structure, distinguishing them from spiral or elliptical galaxies. Irregular galaxies often contain young stars, gas, and dust, and they can be the result of gravitational interactions or collisions with other galaxies.
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
thank you 4 that easy question........because all astronomers are searching galaxy....am i rigth?...and the stars are in the galaxy.....so their cousre called.......star....
The Parallax Method. See the link for more info.
Astronomers determined Earth's location within the Milky Way by studying the distribution of stars, gas, and dust in our galaxy. They used techniques such as star surveys, measuring distances to different parts of the galaxy, and studying the motions of objects in the Milky Way. By comparing these observations with models of the galaxy, they were able to pinpoint Earth's position within it.
Timing is everything as astronomers are making discovers all the time. As of an article posted in March of 2012 - Galaxy J1120+0641, containing the most distant supermassive black hole known to science, is so far away that light from it takes over 13 billion years to reach our planet. This means the light astronomers see from this galaxy is just 740 million years after the Big Bang.
The Milky Way Galaxy.
Wavelengths is what allows astronomers redshift a background galaxy that is covered up. This is due to being close to the foreground galaxy.
An elliptical galaxy
duh were living in a barred galaxy
You might be asking about the Milky Way, the part of the sky where we are looking through the edge of our galaxy.
It's not possible that we could cross a galaxy. But astronomers study galaxies with huge telescopes.
ancient astronomers thought it was spilled milk.
be quit @$$ #**()
Astronomers. They study all things about space.
Observing another spiral galaxy, gives us a good idea about the structure of our own Galaxy.
Astronomers study the Andromeda galaxy to learn more about how galaxies form and evolve, to understand the structure and composition of other galaxies beyond our own Milky Way, and to potentially gain insights into the future fate of our own galaxy.
A black hole or a worm hole :) good luck
