Imaging Discovery of a Wide-Orbit Jovian Planet in a Triple System
July 7, 2016
This discovery was reported widely, including: CNN, The Guardian, History Channel, National Geographic, Spiegel, New York Times, Washington Post, Arizona Daily Star, USA Today, Forbes, Huffington Post, UA News,

According to a new paper co-authored by UA researchers, an ultra-rare spiral structure lives inside a planet-forming disk, some 400 light-years from here.

NASA is bringing together experts spanning a variety of scientific fields for an unprecedented initiative dedicated to the search for life on planets outside our solar system. The Nexus for Exoplanet System Science, or “NExSS”, hopes to better understand the various components of an exoplanet, as well as how the planet stars and neighbor planets interact to support life.
Our UA-led team Earths in Other Solar Systems is one of the two largest projects funded in the new program. For more information on our EOS program see the project website http://otherearths.org

Like galactic storm chasers, UA astronomers are leading an effort to discover how clouds and weather systems change over time on other worlds.
January 7, 2014
Swirling, stormy clouds may be ever-present on cool celestial orbs called brown dwarfs. New observations from NASA’s Spitzer Space Telescope suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter’s “Great Red Spot.”
Scientists Peer Into a Brown Dwarf, Find Stormy Atmosphere
Pointing the Spitzer and Hubble space telescopes simultaneously at a brown dwarf, a UA-led team of astronomers has obtained detailed images of the stormy atmosphere that enshrouds these strange objects, which are not quite planets and not quite stars. Their forecast shows planet-sized clouds and showers of sandy and iron rain.
Hubble and Spitzer See Weather Patterns in Brown Dwarf
Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange worlds.
Exoplanet Caught on the Move
For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves from one side of its host star to the other. The planet has the smallest orbit so far of all directly imaged exoplanets, lying almost as close to its parent star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. Because the star is so young, this discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms.
Life on Earth is thought to have arisen from a hot soup of chemicals. Does this same soup exist on planets around other stars? A new study from NASA’s Spitzer Space Telescope hints that planets around stars cooler than our sun might possess a different mix of potentially life-forming, or “prebiotic,” chemicals.
Disks around Failed Stars – a Question of Age
A team of European astronomers have observed eight Brown Dwarfs, i.e., small and faint objects also known as “failed stars”, with the TIMMI2 infrared sensitive instrument at the ESO 3.6-m telescope on La Silla. From two of these, mid-infrared radiation is detected – for the first time ever from such objects with a ground-based telescope . While the younger Brown Dwarf, aged a few million years, is found to be surrounded by a dusty disk, no warm dust is present around the older ones. The new observations support the following formation hypothesis for Brown Dwarfs: they are born in the same way as “real” stars, by contraction in interstellar clouds of gas and dust . During the later stages of this process, the infalling material is transferred onto the star via a gas and dust disk . This disk – in which planets may possibly form – then disperses with time.

Biology Students Learn to Scan the Stars for Signs of Life
You have to learn to crack eggs if you’re going to cook an omelet. You have to jump in the water if you’re going to learn to swim. And you have to get your hands on telescopes that can search for signs of life beyond Earth if you’re going to study extraterrestrial biology.
