This artist's concept shows a brown dwarf with bands of clouds, thought to resemble those seen on Neptune and the other outer planets in the solar system. By using NASA's Spitzer Space Telescope, astronomers have found that the varying glow of brown dwarfs over time can be explained by bands of patchy clouds rotating at different speeds.

For the first time, astronomers have seen atmospheric bands and waves, reminiscent of those seen in familiar gas giants like Neptune, in brown dwarfs, strange worlds that are not quite planets and not quite stars. Due to their similarity to giant exoplanets, brown dwarfs are windows into planetary systems beyond our own.

Since its debut in fall 2015, UA Online has seen 280 percent year-to-year growth and is on target to meet or exceed Arizona Board of Regents goals. Science classes such as Roger Miesfeld's biochemistry series have contributed to the increase.
During the 2009 total eclipse, the sun's corona became visible to observers on the ground, its swirls and streaks caused by our star's magnetic field interacting with the solar wind. (Image courtesy of Miloslav Druckmüller, Peter Aniol, Vojtech Rušin, Ľubomír Klocok, Karel Martišek, Martin Dietzel)

With the solar eclipse, junior Adriana Mitchell will be "passing the torch of collecting data all across the continent," poised to find answers to long-elusive questions about the sun.
Bright blue dot: Supernovae such as SN 2017cbv appear as "stars that weren't there before," which is why multiple images taken over time are necessary to reveal their true identity. SN 2017cbv lies in the outskirts of a spiral galaxy called NGC 5643 that lies about 55 million light-years away and has about the same diameter as the Milky Way (~100,000 light-years). Data are from the Las Cumbres Observatory Global Supernova Project and the Carnegie-Irvine Galaxy Survey. (Credit: B.J. Fulton/Caltech)

Astronomers have caught the fleeting explosion of a Type Ia supernova in detail. Understanding how they form could have implications for dark energy measurements.

It's an opportunity for course auditors to attend lectures and participate in discussions at a fraction of what regular students pay — and they're allowed to take two classes per year.
Water microbiologist Channah Rock of UA Cooperative Extension says it's important to get the message out about water issues.

Although a statewide campaign is garnering attention for turning wastewater into beer, it's really about educating the public, according to the UA's Channah Rock.
3-D printing is one of the pillars of a startup founded by Gabriel Vasquez in Honduras. The venture is called Craft3D, pronounced "crafted," and its mission is to employ technology to better the lives of Hondurans.
