Our solar system is part of the Milky Way galaxy. In the night sky, its shape is only partially discernible. From one horizon to the other, it appears as a hazy strip of light. However, the structure of the galaxy is hidden by this side view, making it impossible for astronomers to determine the shape […]
Scientists have discovered what appear to be six huge galaxies from the early universe. The objects are so huge that they may alter our understanding of how galaxies form. The findings, published in Nature, make use of data from the James Webb Space Telescope’s infrared-sensing equipment to reconstruct what the cosmos looked like 13.5 billion […]
In order to know how many stars are in the universe, we will first need to find out the number of galaxies. But is this something we can calculate at all? Simply said, the number of galaxies in the universe will be equal to the universe’s size times the typical density of galaxies. Accurately estimating […]
