Web19 sep. 2024 · Hubble’s first plot in 1929 included galaxies only out to a velocity v of about 1,000 kilometers per second, corresponding to a modern distance of about 50 million light-years. By 1931, Hubble and his colleague Milton Humason had extended the plot to include galaxies receding at 20,000 kilo-meters per second. WebThese proto-galactic structures then interact and merge into larger structures now known as galaxies. Present-day galaxies typically have masses of 10 11 solar masses so must have undergone numerous …

The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
Web26 okt. 2024 · For completeness, this is the quote in that link: "Galactic bars develop when stellar orbits in a spiral galaxy become unstable and deviate from a circular path. The tiny elongations in the stars’ orbits grow and get locked into place, forming a bar. The bar becomes even more pronounced as it collects more and more stars in elliptical orbits. Web7 aug. 2015 · Current theories suggest they may be formed through collisions between smaller galaxies. Elliptical galaxies contain very little gas, and so have very low rates of new star formation, which is why they often have a yellowish or reddish hue.
