In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which a lifeless rocky planet around a sun-like star could evolve to have oxygen in its atmosphere.

Jeff Bezos' Blue Origin launched Wednesday from Texas what may be the last test flight for its New Shepard rocket before it carries people later this year.
The rocket lifted off about 12:50 p.m. EDT from the company's spaceport near Van Horn, about 120 miles southeast of El Paso. New Shepard soared into the hazy spring sky, reaching velocity of more than 2,200 mph.

Although there are telltale signs that a volcano is likely to erupt in the near future - an uptick in seismic activity, changes in gas emissions, and sudden ground deformation, for example - accurately predicting such eruptions is notoriously hard.
