The largest known Galaxy is IC 1101, discovered by Sir William Herschel There are four main types of galaxies (Spiral, Lenticular, Elliptical, Irregular) Galaxy's centre? No one knows for sure. Some say it is a super-star, a collection of bright stars or a super-black hole. The centre...

We could see that there are multiple galaxies beyond it… and all these galaxies are moving away from one another. So multiple galaxies… moving away from each other… led to the theory… MALE STUDENT:The big bang theory? MALE PROFESSOR:Exactly. And that theory, that 15 billion years ago ...
It has been estimated that there could be 100 billion planets in the Milky Way alone. Imagine how many galaxies there are; the number of planets in the Universe is mind-bogglingly large.Inverse If a planet orbits within the Goldilocks Zone, it has the chance to support life. The Goldilocks...
In a very real way, we are made of stardust. Nearby stars are valuable scientific targets, and in our galaxy of a hundred billion stars it's a target-rich environment. Telescopes extend that reach to galaxies so far away that the numbers start to lose meaning. The Hubble telescope ...

1. There is more stuff (matter) that we don't see with our telescopes. We call this dark matter. 2. Newton's laws and even GR are wrong on the scale of galaxies and everything bigger. This idea is usually called modified gravity (because we need to modify GR) or Modified Newtonian...
throughout the universe. We know this because we see it concentrated within galaxies and absent in the gaps between galaxies. However, when we talk about the density of matter in the universe, we're imagining spreading everyatomin the universe (three-quarters of which are hydrogen) evenly ...
While any spiral galaxy can look like a pinwheel when views at the correct angle, there are two galaxies named for their Pinwheel shape. These are the... Learn more about this topic: Different Types of Galaxies | Overview & Examples
