- 100 years ago this week, Edwin Hubble announced his monumental discovery that the universe existed beyond our own Milky Way galaxy. He noted that the Andromeda nebula, also called M31, was nearly a million light years away – too remote to be a part of the Milky Way. https://carnegiescience.edu/news/carnegie-science-celebrates-edwin-hubbles-discovery-universe 57 comments space

- Astronomers discover new type of hyperactive star-producing galaxy. Study describes four galaxies, discovered almost by accident, that likely produce stars at the astonishing rate of more than 100 solar masses every year.

- Study shows that periods of seismic quiet occur immediately before eruptions and can thus be used to forecast an impending eruption for restless volcanoes. The duration of the silence can indicate the level of energy that will be released when eruption occurs. Longer quiet periods mean a bigger bang https://carnegiescience.edu/node/2050 15 comments science
