Astronomers announced today that they have discovered a new type of planet -- a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldn't form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas giant. This planet, though, is all solids and much bigger than previously discovered 'super-Earths,' making it a 'mega-Earth.'
It is often claimed that periorbital dark circles are caused by tiredness or working too hard or even just staying up late. While this can be true, the truth is that your genes play a huge role here. So what exactly is happening when you get dark circles under or around your eyes?
The problem with visionary research is that it often does not see the light of day. Facilities are often simply not available, or the experts needed to put scientific theories to the test cannot be found. This is true for a number of research fields, including cutting edge thinking on the future of ...
(Phys.org) —The amount of time it takes to mathematically simulate the path of ash from a volcano eruption or a satellite collision can take hours, even days. However a new method, the Conjugate Unscented Transform (CUT), has shortened the process to minutes.
This volume is full of unexpected revelations, not for the squeamish, starting with the fact that the preferred plural of “octopus” is “octopuses,” not “octopi.” Octopuses, we learn, can lurch onto land and can change color and shape in seconds. After 272 pages in the company of these animals, they no longer seem weird because of their four pairs of arms lined with suction cups. They’re weird because of the ways they contradict our ideas about intelligence.
A galaxy has thrown out a star cluster towards Earth at more than two million miles per hour. But it is, thankfully, likely to miss our planet and “drift through the void between the galaxies for all time,” says the Harvard-Smithsonian Center for Astrophysics.
