The highest elevations in continental Portugal are found in the Serra da Estrela region. A few peaks here approach 6,500 ft (1,980 m). In valleys between mountain ridges, lakes routinely freeze even during Portugal's generally moderate winter climate. Some of the higher elevation lakes of this region remain frozen until mid-March. The on...

One of the trademarks of the Star Wars film episodes is the dreaded Death Star battle station that fires a beam of directed energy powerful enough to blow up planets. The real universe has such fireworks, and they are vastly more powerful than the Star Wars creation. These extragalactic jets are tearing across hundreds of light-years of space at 98 percent the spe...

Astronomers have spent decades trying to determine the oddball behavior of an aging star nicknamed "Nasty 1" residing in our Milky Way galaxy. Nasty 1 was identified as a Wolf-Rayet star, a rapidly evolving star that is much more massive than our sun. The star loses its hydrogen-filled outer layers quickly, exposing its super-hot and extremely bright helium-burning...

I am very familiar with Trifolium repens, or white clover, but I did not recognize it in Bruce Brethauer's (aka Glichidman@Flickr) close-up of Trifolium repens florets (a floret is a small flower in a composite of flowers). Thanks Bruce, for making me see a familiar plant species from an entirely different perspective.
There is a good chance that you have seen a Trifolium repens plant today. O...
