The Science Behind Hawaii’s ‘Smiley Face’ Volcano

The Science Behind Hawaii’s ‘Smiley Face’ Volcano

[source] A “smiling” volcano has gone viral. Hawaii’s Kilauea volcano has been actively erupting since 1983, and it’s one of the most active volcanoes in the world, according to the U.S. Geological Survey (USGS). But the volcano received more attention recently when the volcano’s lava formed what looks like a smiley face. The smiley face appeared in a lava lake crater on the west flank of Pu’u ‘O’o, on Kilauea’s East Rift Zone, according to Janet Babb, a geologist with the USGS’ Hawaiian Volcano Observatory. [Explosive Images: Hawaii’s Kilauea Erupts for 30 Years] Pu’u ‘O’o also recently made headlines when the lava flow reached the ocean for the first time in three years. While it may seem like Kilauea was smiling for the cameras, the “face” has a more scientific explanation: The bright spots and incandescent line that created the face shape were produced by normal volcanic activity. As a lava lake circulates, lava upwelling and downwelling will occur on opposite sides of the lake, according to the Hawaiian Volcano Observatory. This often results in a spattering of molten lava, which creates bright spots on the dark-colored, semi-solid lake surface. Circulation can also cause sections of the surface to pull apart, revealing the lava beneath and creating lines. By chance, these processes occurred in a pattern that created the smiling image, Babb said. “The Pu’u ‘O’o lava lake just happened to produce two spattering sources (bright dots) that have been interpreted as ‘eyes’ and an incandescent line that has been interpreted as a ‘mouth’ — with the two lake surface features located relative to each other to produce the... read more
From atop Mauna Kea, UH scientists are finding exoplanets, boosting the chance of discovering alien life

From atop Mauna Kea, UH scientists are finding exoplanets, boosting the chance of discovering alien life

[source] University of Hawaii astronomers were part of a globe-spanning team that recently announced the discovery of more than 100 new planets orbiting stars beyond our own solar system. These new exoplanets, confirmed in part through observations made from Hawaii-based telescopes, reveal an unprecedented range of diversity in the places and ways in which planets can form. And the study’s findings further raise the probability of the existence of extraterrestrial life. “One of my favorite quotes comes to mind, from Arthur C. Clarke,” said Evan Sinukoff, a co-author of the study and a graduate student at the UH Manoa Institute for Astronomy. “‘Two possibilities exist: Either we are alone in the universe or we are not — both are equally terrifying.’” This artist’s concept shows a crop of more than 100 planets, discovered by NASA’s Kepler Space Telescope. Those planets include four in Earth’s size range orbiting a single dwarf star. NASA/JPL “We all know how easily fear can motivate people,” he laughed, then added, “What keeps me going into work every day is my desire for exploration and the notion that I’m contributing a chapter to a journey thousands of years in the making … and coffee.” The Flea And The Street Lamp To find these new planets, an international group of astronomers collaborated on a specific set of observations made with NASA’s orbiting Kepler Space Telescope, launched in 2009. Sinukoff said they started by taking measurements of more than 10,000 stars, in five different patches of the sky, each of which they monitored for three months. They looked for specific changes in a star’s brightness, potentially caused by an... read more

Richard Ha Expresses PUEO’s Support for TMT

Richard Ha Expresses PUEO’s Support for TMT

Yes, the state should allow TMT on Mauna Kea By Richard Ha (Editioral Published by Star Advertiser) September 7, 2016 Our group, Perpetuating Unique Educational Opportunities (PUEO), is made up of highly respected members of the Hawaiian community. We represent folks who believe our children are as competent as any in the world. We are about keiki education.  We are also about making sure our culture is not left behind as we move into the future. We can multitask. The Big Island has the lowest median family income, the highest rate of homelessness and the highest suicide rate. PUEO recognizes that education is the great equalizer. We believe through education, taking advantage of the resources around us and integrating our culture into what we learn, we can not only do better, we can lead the world. PUEO stepped up when we learned that Hokukea, the small University of Hawaii at Hilo teaching telescope, would go from Mauna Kea, the best viewing site in the world, down into Hilo, the rainiest city in the world.  Why? We also felt we needed to support astronomy in general and the Thirty Meter Telescope (TMT) in particular. That is why PUEO entered the contested-case hearing supporting the TMT, which has a track record of doing the right thing. The president of TMT, Henry Yang, is a humble man of the people, someone you can do business with on a handshake. Our people came from the south. Though they had not seen the northern skies, they used their knowledge of the stars and launched their canoes. Today, on Mauna Kea, we are in these... read more
