In today’s guest post, Caitlin Doughty discusses how carbon lines are misidentified and their impact on cosmology.
There she blows! A detective case tracking the motion of material ejected from a star to figure out when the star exploded.
High resolution observations of the Orion Nebula show a complex collision between two extreme types of gas.
Simulations of the first groups of stars display a variety of shapes and sizes, and may provide clues as to where their ancestors are hiding today
Major mergers (collisions between two galaxies of similar size) are some of the most dramatic cosmic events. But in the grand scheme of things, how important are they, really?
Giant galaxies are built out of a patchwork of many smaller galaxies, drawn together by gravity. But the stars in these precursor galaxies are disimilar. How does this process of galactic assembly affect what we can infer about star formation?
