Double Post: Mini Stars & Morning Micrometeorites on Mercury

Alliteration is accessible to all! Okay I’m done. Start some science! Really done this time.  Today’s double post covers the smallest of stars, still larger than most planets, and the only weather Mercury will ever have. Humans are naturally interested in the extremes, the biggest, smallest, fastest, hottest, coldest, and every other characteristic outlier.  With stars, being so huge and powerful, we are often more interested in the largest, hottest, and most energetic.  Though on the opposite end of the spectrum, Cambridge University astronomers have discovered the smallest star in the known universe. The star, a red dwarf, has the...

A New Theory of Life: Physics to Evolution

When Isaac Newton quantified gravity, his theory explained how everything in the world around us behaved in it’s presence.  It opened a door to an understanding of something fundamental, yet elusive in explanation.   Then Einstein came along and too a step back, finding a larger more comprehensive theory of gravity, one that explained the strange things that happen in the grand universe, and could even explain things that Newton’s gravity could not, such as the odd orbit of Mercury around the Sun.  The greatest part of Einstein’s theory is this: If you use it to describe every day objects, it...

Happy Friday: New Photo Release from New Horizons!

It’s like a birthday to an astronomer when new science data comes in.  I will always love seeing new photos from the Pluto system, and with terabytes of data left to download from new horizons, we’re going to have a lot of presents over the next few months.  Our latest gift gives us some new images from the flyby, showing surface features and atmosphere.  These are stunning. These incredible photos show the surprising complexity of surface features on Pluto.  The gorgeous variation in the surface is reminiscent of Mars, amazing considering the lack of sunlight this distant world receives. The long...
