Astronomy-related article

This week delve into any astronomy-related article you’d like–it’s all part of the universe! It could be primordial black holes, quasars, colliding galaxies, the largest stars, etc., anything that piques your interest! Please refrain from posting articles lacking in scientific results (constellations, astrology, etc.) though. If you post on something we consider ‘non-scientific’ or ‘not astronomy-related, you’ll be asked to redo/resubmit your summary.

You’re welcome to use any reputable scientific news source (major newspapers, Scientific American, Physics Today, National Geographic, etc.) or sites that aggregate astronomy news. Here are some good starting points:

• Spaceref.com: Good Astronomy news site
• Science Daily: Astronomy (and other science) news
• Spaceflight Now: Cool news on space flights

For this discussion, it is especially important that you reference your source.
