Feb 24 Recap

Some topics we talked about:

1. Astronomers found Type Ia SNe born differently in some elliptical galaxies than we originally thought. Read the Nature paper here.

2. Four dwarf galaxies relatively nearby (few hundred million light-years away), are in the process of merging, which usually happened billions of light-years away. Read the story here.

3. By studying the age and chemical properties of globular star clusters in our galaxy, astronomers believe at least a quart of star clusters are invaders from other galaxies. Read the story here.

4. Primitive stars have been found outside Milky Way galaxy. Read the news release here.
