Astronomers use astro-comb to seek Earth-like exoplanets

Astronomers looking for exoplanets are using a fine-toothed comb – a fine-toothed astro-comb, to be precise. And just to make sure it works, the first planet they’ll be looking for is Venus. Developed by astronomers Chih-Hao Li and David Phillips of the ... [Published Gizmag - 13 hours ago]

Quotes

...of Mars that is usually only possible for Earth," says MAVEN remote sensing team member Justin Deighan of the University of Colorado, Boulder. "On Earth, ozone destruction by refrigerator CFCs is the cause of the polar ozone hole. On Mars, ozone is just as easily destroyed by the byproducts of water vapor breakdown by ultraviolet sunlight. Tracking the ozone lets us track the photochemical processes taking place in the Martian atmosphere. We'll be exploring this in more complete detail during MAVEN's primary science mission."
"This set of research really delivers on the promise of IRIS, which has been looking at a region of the Sun with a level of detail that has never been done before" said Bart De Pontieu, the project's science lead at Palo Alto, California-based Lockheed Martin
"These nanoflares, as well as the energetic particles possibly associated with them, are difficult to study because we can't observe them directly" said Paola Testa from the Harvard-Smithsonian Center for Astrophysics (CfA) in the US
Asked if a deal for the release of the girls had been finalised, the head of the National Information Centre, Mike Omeri, said: "No. That part has not been agreed but we are inching closer and closer."
