An opportunity to experience an unseen side of Florence is now possible via a new smartphone App which brings the past to life through the eyes of an ordinary 15^th century Florentine.

In the Italian Renaissance city of Florence, tourists often take the well-trodden routes of seeing the iconic artworks of Botticelli’s Birth of Venus and Michelangelo’s David.

Now, this free history App is available providing an unconventional tour in which you walk in the footsteps of wool worker Giovanni, hunting for statues, street tabernacles and piazzas whilst being told vivid tales about the city. It is based around an interactive map, complete with audio directions and storytelling. The Hidden Florence App opens up a city overlooked by conventional tourist guides. (more…)

‘Finally American’: Poet Discusses Impact of Inaugural Poem

Is the inaugural poem a new sub-genre of poetry? According to two practitioners of the form, the answer might be “yes.”

Poet Richard Blanco and Yale professor Elizabeth Alexander, two of only five poets in history to have created works for a presidential inauguration, came together on Feb. 5 for a poetry reading and dialogue about their unique shared experience. Blanco read his work “One Today” at President Barack Obama’s second inauguration, while Alexander read her “Praise Song for the Day” at Obama’s first. Their discussion was hosted by Ezra Stiles College master Stephen Pitti. (more…)

Can Life Emerge on Planets Around Cooling Stars?

Astronomers find planets in strange places and wonder if they might support life. One such place would be in orbit around a white or brown dwarf. While neither is a star like the sun, both glow and so could be orbited by planets with the right ingredients for life.

No terrestrial, or Earth-like planets have yet been confirmed orbiting white or brown dwarfs, but there is no reason to assume they don’t exist. However, new research by Rory Barnes of the University of Washington and René Heller of Germany’s Leibniz Institute for Astrophysics Potsdam hints that planets orbiting white or brown dwarfs will prove poor candidates for life.

A Prime Seat to a Once-in-a-Lifetime Spectacle

Hosted by world-renowned astrophotographer Adam Block at the UA’s Mount Lemmon SkyCenter, a group of sky and astronomy enthusiasts watched Venus cross the sun from the highest vantage point in Southern Arizona.

On Nov. 24, 1639, in the tiny village of Much Hoole not far from Liverpool, England, a poor farmer’s son and self-taught astronomer affixed a sheet of paper in front of a makeshift telescope pointed at the sun and waited.

Thirty-five minutes before sunset, a dark, round spot appeared right next to the bright disc that was the sun’s face projected on the paper, and made Jeremiah Horrocks, only 20 years old at the time, the first known human to predict, observe and record a transit – the passage of a planet across the sun as seen from Earth.

Almost 373 years later, a group of sky enthusiasts is gathered beneath the dome of one of the University of Arizona’s observatories on Mount Lemmon just north of Tucson, Ariz. (more…)

NASA Discovers First Earth-Size Planets Beyond Our Solar System

PASADENA, Calif. — NASA’s Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet’s surface, but they are the smallest exoplanets ever confirmed around a star like our sun.

The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1,000 light-years away in the constellation Lyra. (more…)

NASA’s Kepler Confirms Its First Planet in Habitable Zone

PASADENA, Calif. — NASA’s Kepler mission has confirmed its first planet in the “habitable zone,” the region around a star where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets.

The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun. The planet is about 2.4 times the radius of Earth. Scientists don’t yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets. (more…)

NASA Develops New Game-Changing Technology

Two NASA California centers have been selected to develop new space-aged technologies that could be game-changers in the way we look at planets from above and how we safely transport robots or humans through space and bring them safely back to Earth.

NASA’s Jet Propulsion Laboratory in Pasadena, Calif., will use advanced compound semiconductor materials to develop new technologies for the High Operating Temperature Infrared Sensor Demonstration. The higher the temperature at which an infrared detector can operate, the less power is required to cool it. Reduced power needs can translate into operational cost and system weight savings. If successful, this sensor technology could be used in many future NASA Earth and planetary science instruments, as well as for U.S. commercial and defense applications. (more…)

Clocking Neptune’s Spin

*By tracking atmospheric features on Neptune, a UA planetary scientist has accurately determined the planet’s rotation, a feat that had not been previously achieved for any of the gas planets in our solar system except Jupiter.

A day on Neptune lasts precisely 15 hours, 57 minutes and 59 seconds, according to the first accurate measurement of its rotational period made by University of Arizona planetary scientist Erich Karkoschka.

His result is one of the largest improvements in determining the rotational period of a gas planet in almost 350 years since Italian astronomer Giovanni Cassini made the first observations of Jupiter’s Red Spot. (more…)
