Watching a meteor race across the night sky is a romantic experience. And now it can be a scientific one as well. The new Fireballs in the Sky app lets you track fiery objects and enter them into a research database.
Scientists at Curtin University in Australia are tracking fireballs (meteors that are very large and bright) using cameras across Australia in a project called the Desert...
Under a microscope, the tiny trap of a carnivorous plant becomes an impressive gaping maw. Rootless and adrift in its wetland habitat, the humped bladderwort (Utricularia gibba) preys on water fleas and other small invertebrates. Organisms that trip the plant’s sensory hairs are sucked inside bladderlike traps to be digested.

Space may be peppered with “black holes.” This was suggested at the American Association for the Advancement of Science meeting in Cleveland by astronomers and physicists who are experts on what are called degenerate stars…. Degenerate stars are made of densely packed electrons and nuclei, or cores of atoms…. Because a degenerate star is so dense, its gravitational field is very...01/11/2014 - 09:31 Astronomy
Standing on a mesa high above the town of Rifle, Colo., Andres Aslan is having a hard time staying quiet.
