Of late, my ScienceSprings blog has been tilting heavily toward Astronomy. This is because of the availability of both American (NASA) and European (ESO, ESA) material at Twitter, Facebook and Google+, web sites.

There are great graphics, many many links back to original and explanatory material.

If you like, you can follow the blog or the Twitter feed for items of interest.
