STEM Saturday Post Promotion #27: Exploring supernovas and mass extinction events

When is a Supernova explosion dangerous to Earth's inhabitants? @jorgebgt answers that question in We are safe in the Universe.

Welcome to our 27^th STEM Saturday post promotion on the Steem blockchain. In celebration of the occasion, I have once again promoted a Popular STEM post to the top of the /promoted list.

This marks the twenty-seventh consecutive Saturday that our community has held the top of the /promoted page.

As previously announced, the promoted post will be pinned in our community, and it will remain pinned until payout time or until it drops out of the top-2 promoted posts for our community.

The Post

This week's promoted post is We are safe in the Universe from @jorgebgt.

As with prior weeks, the post was passed through three separate online plagiarism checks before promotion.

Here is the post at the top of /promoted:

Promotion Cost

In order to promote the post, I burned 0.05 SBD (equivalent to about ¹/₄ STEEM) by sending it to @null with the memo field set to: @jorgebgt/we-are-safe-in-the-universe.

The Community

The Popular STEM community is intended to be a place for accessible STEM conversations (Science, Technology, Engineering, and Mathematics). If you have an interest in STEM topics, please come join us!

About STEM Saturday

If members would like to have your own STEM content considered for future promotions, please come join us and start contributing. I don't know how long I'll be continuing the tradition, but while I do, here are the minimum requirements for consideration (subject to change without notice ;-).

1. Original, plagiarism-free content
2. Minimum word count: currently 300 words, but this may be adjusted.
3. The content must not be cross-posted on other web sites or blockchains. Correct use of the #steemexclusive tag is encouraged.
4. English language. (sorry, it's the only one I know)
5. Because a post leaves /promoted at payout time, posts created shortly before STEM Saturday may be more likely to be chosen than older posts.

All community members are invited to create original and exclusive content that can be considered for future promotions.

Please help grow the science & technology audience on the Steem blockchain by following the Science and Technology on the Social Blockchain Facebook page then liking & sharing our links!
