The carnival has been running for over six years now, and we continue to find new and amazing stories and contributors, so if you have any interest at all in space science or astronomy, this is the place to be! And if you'd like to join our stable of writers, just contact us via the link at the end to see if you qualify (spoiler: you do!)

We have a good turn-out this week, so let's get started:

Carnival of Space #383

Carnival of Space #383Another week, another Carnival of Space. We've been quiet here at Urban Astronomer while I work on a new project and (on a personal note) prepare for the birth of another child. But there's always time to curate a Carnival of Space so let's get started.

Mars vs the comet

Image Credit: Allen VersfeldLate last year, word started spreading through the local astronomical community that an exciting event was coming up: An Oort cloud comet named C/2013 A1 (Siding Spring) would be passing so close by Mars that there was a chance it might hit.  If it did, we on Earth would be treated to a spectacularly rare astronomical display of a comet slamming into a rocky planet.  The planetary science community were simultaneously excited about what they could learn from the resulting multi-megaton blast, and frightened for the possible loss of all their various robotic missions exploring the red planet.
