Ah my friends, astrophysics. Even if it lacks the complexity of ecology, it is still a cool science. Kinda. In fact, the cosmos has several similarities with Nature (and with my ex), in particular, they are impressively beautiful and implacably deadly.
Did you know that there are hundreds of billion stars in our galaxy alone? And that there are hundreds of billion galaxies in the observable universe? Vertiginous. That reminds me of Fermi’s “where is everybody?”. Anyway, the point of this post was to point out to a very nice collection of photos put online by NASA, here.
So next times you science policy deciders vote for big budgets for physicists, look what they do at work. They take pretty picture. We can do that too!
