They have no defined shape nor structure and may have formed from collisions, close encounters with other galaxies or violent internal activity. ]]> 2021-04-15 13:48:01 UTC https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421042844 https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421049825 Elliptical galaxies are round and smooth.

Are composed mostly of old stars. This indicates that the bulges and halos of spiral galaxies probably formed through the primordial collapse of individual gas clouds early in the history of the Universe.]]> 2021-04-15 13:49:44 UTC https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421052266 s1838654 https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421084276 The universe is a violent place, and collisions between galaxies are frequent — indeed, the Milky Way is due to crash into the Andromeda Galaxy in a few billion years. When two spirals collide, they lose their familiar shape, morphing into the less-structured elliptical galaxies.]]> 2021-04-15 13:55:39 UTC https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421084276 s1838654 https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421106821 The Milky Way – the galaxy that includes Earth and our solar system – is an example of a spiral galaxy. ... Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole.]]> 2021-04-15 13:59:33 UTC https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421106821 s1985181 https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421111360 Irregular galaxies get their odd shapes in many ways. One way irregular galaxies are formed is when galaxies collide or come close to one another, and their gravitational forces interact. Another source of irregular galaxies may be very young galaxies that have not yet reached a symmetrical state. Also known as peculiar galaxies, these non-conformists are thought to make up around a quarter of all known galaxies. In general, irregular galaxies contain large amounts of gas and dust, and can exhibit a significant degree of star formation activity.

They are preferentially found close to the centers of galaxy clusters. Elliptical galaxies range in size from tens of millions to over one hundred trillion stars.]]> 2021-04-15 14:01:02 UTC https://padlet.com/s1838654/nrer4c7kcuxda9qp/wish/1421114731
