The galaxy ESO 300-16 looms over this captivating image from the Hubble Space Telescope. This galaxy, which lies 28.7 million light-years from Earth in the constellation Eridanus, is a ghostly assemblage of stars that resembles a sparkling cloud. A rogues gallery of far-off galaxies and foreground stars finishes this astronomical portrait, which was recorded by the Advanced Camera for Surveys (ACS).
Hubbles In-depth Exploration
This specific observation is among a series that intends to get to know our stellar neighbors. Incredibly, about three-quarters of the known galaxies believed to lie within 10 megaparsecs of Earth have already been observed by Hubble in adequate detail to fix their brightest stars and establish the distances to these galaxies. A team of astronomers proposed utilizing small spaces in Hubbles observing schedule to examine the staying quarter of the nearby galaxies.
Comprehending Astronomical Distances
The megaparsec– suggesting one million parsecs– is an unit of length utilized by astronomers to chart the mind-bogglingly big ranges included in astronomy. The motion of Earth around the Sun implies that stars appear to slightly shift versus extremely far-off stars over the course of a year.

An awesome image of the galaxy ESO 300-16, located 28.7 million light-years away in the constellation Eridanus, captured by the NASA/ESA Hubble Space Telescope. Incredibly, about three-quarters of the known galaxies thought to lie within 10 megaparsecs of Earth have currently been observed by Hubble in sufficient information to resolve their brightest stars and develop the ranges to these galaxies. A group of astronomers proposed using little spaces in Hubbles observing schedule to investigate the remaining quarter of the close-by galaxies.
