Popocatépetl Volcano Volcanic Ash Advisory: CLEAR VA EM to 20000 ft (6100 m)

Background:

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano.  The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater.  The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. 
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano.  The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone.  Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano.  Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian

10 billion Milky Way stars might have habitable exoplanets after all

A research team led by the recipient of a U.S. National Science Foundation Faculty Early Career Development grant used computer simulations to determine that white dwarf stars have greater potential to host habitable planets than previously realized. The team concluded that many more stars in the Milky Way galaxy might be home to planets that could support life.

There are approximately 10 billion white dwarf stars in the Milky Way. Because such stars are colder than others, scientists have thought they likely would not support habitable exoplanets. Led by Aomawa Shields, a University of California, Irvine professor of physics and astronomy, researchers used a supercomputer provided by the NSF National Center for Atmospheric Research in Boulder, Colorado, to simulate conditions on a theoretical rocky planet orbiting a white dwarf. Using data from real exoplanets orbiting the non-white dwarf star Kepler-62, the researchers found that their simulated rocky planet could have liquid water if it closely orbited a white dwarf and had certain rotational characteristics. Their findings were published in The Astrophysical Journal.

“Not much consideration has been given to these stars’ ability to host habitable exoplanets,” says Shields. “Our computer simulations suggest that if rocky planets exist in their orbits, these planets could have more habitable real estate on their surfaces than previously thought.”
