PASADENA, Calif. — NASA has selected a new mission, set to launch in 2016, that will take the first look into the deep interior of Mars to see why the Red Planet evolved so differently from Earth as one of our solar system’s rocky planets.
The new mission, named InSight, will place instruments on the Martian surface to investigate whether the core of Mars is solid or liquid like Earth’s, and why Mars’ crust is not divided into tectonic plates that drift like Earth’s. Detailed knowledge of the interior of Mars in comparison to Earth will help scientists understand better how terrestrial planets form and evolve.(more…)
Researchers say Phoenix Cluster activity may cause scientists to rethink how galaxies evolve
A National Science Foundation-funded radio telescope in Antarctica has found an extraordinary galaxy cluster that may force astronomers to rethink how galaxy clusters and the galaxies that inhabit them evolve.
The galaxy cluster was discovered some 5.7 billion light years from Earth by the 10-meter wide South Pole Telescope (SPT) located at NSF’s Amundsen-Scott South Pole Station in Antarctica, which is funded by NSF’s Office of Polar Programs. (more…)
A third of Earth’s organisms live in rocks and sediments, but their lives have been a mystery
By some estimates, a third of Earth’s organisms live in our planet’s rocks and sediments, yet their lives are almost a complete mystery.
This week, the work of microbiologist James Holden of the University of Massachusetts-Amherst and colleagues shines a light into this dark world.
In the journal Proceedings of the National Academy of Sciences (PNAS), they report the first detailed data on methane-exhaling microbes that live deep in the cracks of hot undersea volcanoes. (more…)
The Umbrella Corporation’s deadly T-virus continues to ravage the Earth, transforming the global population into legions of the flesh eating Undead. The human race’s last and only hope, Alice, awakens in the heart of Umbrella’s most clandestine operations facility and unveils more of her mysterious past as she delves further into the complex. Without a safe haven, Alice continues to hunt those responsible for the outbreak; a chase that takes her from Tokyo to New York, Washington, D.C. and Moscow, culminating in a mind-blowing revelation that will force her to rethink everything that she once thought to be true. Aided by newfound allies and familiar friends, Alice must fight to survive long enough to escape a hostile world on the brink of oblivion. The countdown has begun. (more…)
A team of explorers discover a clue to the origins of mankind on Earth, leading them on a thrilling journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race. (more…)
A new study finds that the pattern of heat coming from volcanoes on Io’s surface disposes of the generally-accepted model of internal heating. The heat pouring out of Io’s hundreds of erupting volcanoes indicates a complex, multi-layer source. These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus.
A map of hot spots, classified by the amount of heat being emitted, shows the global distribution and wide range of volcanic activity on Io. Most of Io’s eruptions dwarf their contemporaries on Earth. (more…)
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…)
Global warming villain CO2 may have a surprisingly green future
The next frontier in the search for renewable energy lies less than two miles from where you are now.
Unless you’re reading this on the International Space Station.
Geothermal heat a mile or two deep in Earth’s crust is a potential source of energy that could be tapped by an unlikely carrier: carbon dioxide (CO2), the central villain in global warming. That energy, unlike solar and wind, could be easily turned on and off without the intermediate step of being stored in a battery. And it would be constant and reliable. (more…)
