Welcome, come in to the 444th Carnival of Space! Â 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 now, on to this week’s stories! Our first stop is over at Aartscope, where Astroswanny continues a series of articles on Asteroid Astrometry, virtual impactors and the uncertainty parameter pending the close approach of 2013 TX68 on March 5th.Next, at Planetaria, they explore the â€˜Cauliflowerâ€™ silica formations on Mars: are they evidence of ancient life?Then Ryan Marciniak tells us that seeing an aurora means the Sun isn’t killing you.Â The harmful radiation from our life giving star could destroy all surface life, but Earth protects us and gives us a lovely glow to keep us entertained in the process.Next, we jump over to an unusual place for a timely topic – we head over to the Daily Beast for Kimberly Arcand’s and Megan Watzke’sAn op-ed on women in STEM.Then we head over to the Venus Transit, to read about the The Winter Hexagon shines in the sky.Finally, we come back to my home, Universe Today, to read about Rosettaâ€™s Philae Lander permanently going to sleep after it finished it’s mission to the Comet 67-P.That’s it for this week’s Carnival!
