Welcome, come in to the 513th Carnival of Space! The Carnival is a community of space science and astronomy writers and bloggers, who submit their best work each week for your benefit. I’m Susie Murph, part of the team at Universe Today and CosmoQuest. So now, on to this week’s stories!

First, we head over to The Evolving Planet, where Donna Mapacpac tells us how Mice were sent to space to test a bone-building drug developed at UCLA. Then Donna shares a few fun facts about our solar system that you may not know!

Over at the Chandra X-Ray Observatory website, they’re Watching a Volatile Stellar Relationship by observing the red giant R Aquarii.

Finally, we return here to Universe Today. First up, Matt Williams tells us about how These 25 Billion Galaxies are Definitely Living in a Simulation. Then Evan Gough asks the question What Made this Mysterious Pit on Mars? Impact Crater or Natural Collapse? Finally, Fraser Cain presents a new video in the Guide to Space series – Construction Tips from a Type 2 Engineer: Collaboration with Isaac Arthur.

Thank you for all of your stories – we’ll see you next week!

And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space. If you’ve got a space-related blog, you should really join the carnival. Just email an entry to carnivalofspace@gmail.com, and the next host will link to it. It will help get awareness out there about your writing, help you meet others in the space community – and community is what blogging is all about. And if you really want to help out, sign up to be a host. Send an email to the above address.
