Hubble Telescope tracks a dwarf galaxy’s stars to map out dark matter

of Hubble Space Telescope teeth, Dark matter Concentrated in the centre of a nearby dwarf galaxy, this is a discovery that saves the standard model of the galaxy. CosmologyThis model essentially predicts that dark matter is “cold,” but recent findings are beginning to suggest that this matter is “warm.” However, these new observations favor the Standard Model.

Dark matter is an invisible substance that is believed to make up the universe. 85% of the mass of the universeBut no one knows what dark matter actually is, or how it behaves. Our best guess is that it’s “cold.” In other words, it’s predicted to be made up of low-energy particles that don’t fly around everywhere, but rather move slowly and come together to form giant halos within which galaxies grow. The concept of cold dark matter (CDM) and its impact on the formation of structure in the universe is a mystery. The Universe It’s an important part of our current situation. Standard Model This part of the cosmology is known as lambda CDM (lambda stands for Dark Energy).
