    What the swirling storms on alien worlds can tell us about the climate on Earth. A somewhat alarming new phrase entered the American lexicon when parts of the United States were plunged into an especially bitter deep freeze in January 2014: “polar vortex.” News reports cast the polar vortex as a previously unknown phenomenon that had suddenly descended upon the country.

    Past lunar missions have detected evidence of large ice deposits in permanently shadowed regions near the Moon’s south pole. Such ice could provide astronauts with drinking water, oxygen, and rocket propellants, reducing the cost of lunar operations. But new research has found that astronauts might not have to dig very deep or journey especially close to the Moon’s poles to find water ice.

    This is an authorized translation of an Eos article. Esta es una traducción al español autorizada de un artículo de Eos. Los cinturones polvorientos de escombros provenientes del nacimiento de estrellas son extensos y dinámicos, alimentados por colisiones frecuentes entre exocometas y agitados por la gravedad de planetas cercanos, según un estudio reciente publicado en Astronomy & Astrophysics. Los hallazgos ofrecen nuevas perspectivas sobre el proceso de formación planetaria.

    A small star with a planet companion appears to be on a high-speed trip around the center of the Milky Way and could be destined to escape the galaxy. If confirmed, the system would be the first “hypervelocity” star-and-exoplanet combo yet seen, raising questions about how a star could maintain its grip on a planet as they’re both booted from the galaxy’s core.

    Dusty belts of debris from the birth of stars are wide and dynamic, fed by frequent collisions between exocomets and stirred by the gravity of nearby planets, according to a recent study published in Astronomy & Astrophysics. The findings offer new insights into the planet-building process. The belts are analogous to the solar system’s Kuiper Belt, a doughnut-shaped zone beyond the orbit of Neptune that holds hundreds of millions of icy bodies.
