Other Solar Systems More Habitable Than Ours
2012-12-04 05:14:58

Lee Rannals for redOrbit.com - Your Universe Online A new study has found that many planets in other solar systems may be more habitable than our very own. Astronomers and geologists at Ohio State University teamed up to search for alien life in a whole new way; by studying eight "solar twins" of our sun in order to measure the amounts of radioactive elements they contain. Those stars came from a dataset recorded by the High Accuracy Radial Velocity Planet Searcher (HARPS)...

Breaking Through The Crust: Unraveling The Magma Mystery
2012-11-30 13:54:20

April Flowers for redOrbit.com - Your Universe Online Even though two-thirds of the Earth's solid surface is covered with oceanic crust, scientists still do not entirely understood the process by which it is made. But a recent study from the Carnegie Institution for Science, which analyzed more than 600 samples of oceanic crust, reveals a systemic pattern that alters long-held beliefs about how the process works. Findings of this study, published in the journal Nature, explain a...

Scientists Use TNT To Predict Volcanic Explosions
2012-11-26 15:50:37

[WATCH VIDEO: Using TNT To Understand Volcanoes] Lee Rannals for redOrbit.com — Your Universe Online Researchers chucked some TNT into the Earth in order to study maar craters and help predict the next big volcano. University at Buffalo scientists reported in the journal Geophysical Research Letters that they performed experiments to help examine maar carters, which resemble the bowl-like cavities formed by meteorites. By measuring meteorite impacts, scientists are able...

New Zealand Volcano From Lord Of The Rings Unexpectedly Erupts While Scientists Monitor Active Neighbor
2012-11-22 12:18:51

Lawrence LeBlond for redOrbit.com - Your Universe Online After more than a century of dormancy, a New Zealand volcano has erupted a second time in four months, sending a column of ash more than a mile into the sky and forcing school children and tourists to flee from the area, according to local reports. The Mount Tongariro volcano erupted at 1:25 p.m. local time (00:25 GMT) on November 21, and spouted off for about five minutes before settling back down. While scientists said there...

Scientists Present Recent Findings On The Subsurface Biosphere
2012-11-19 14:27:31

National Science Foundation "Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?" So wrote Jules Verne almost 150 years ago in A Journey to the Center of the Earth. Verne probably couldn't have imagined the diversity of life that researchers observe today under the ocean floor. Scientists affiliated with the National Science Foundation (NSF) Center for Dark Energy...

April Flowers for redOrbit.com - Your Universe Online According to an international team of scientists, led by the University of Durham, UK, the recent storms that have battered the east coast of America may have been much more frequent in the region 450 million years ago. The findings of their study, published in the journal Geology, pinpoint the positions of the Equator and the landmasses of the USA, Canada and Greenland, during the Ordovician Period 450 million years ago,...

Volcanic Eruptions Predicted With Satellite Imagery
2012-11-05 14:28:53

Brett Smith for redOrbit.com - Your Universe Online In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery. Using Interferometric Synthetic Aperture Radar (InSAR) over the active volcanoes in Indonesia's west Sunda arc, the vulcanologists from University of Miami uncovered evidence that showed the ℠inflation´ of several volcanoes prior to...

Hawaiian Volcanoes Compete For The Same Magma Supply
2012-10-24 06:12:27

April Flowers for redOrbit.com - Your Universe Online About 50 miles underground, there is a deep connection between two of Earth's most notable volcanoes, Hawaii's Mauna Loa and Kilauea, that could explain some of their enigmatic behavior. A new study, led by Rice University, is the first to model paired volcano interactions. It explains how a link in Earth's upper mantle could account for the competition between Kiluea and Mauna Loa for the same deep magma supply. The results of this...

Trigger For Explosive Volcanic Eruptions Identified
2012-10-13 09:27:11

Lee Rannals for redOrbit.com — Your Universe Online Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports. University of Southampton researchers investigated crystal cumulate nodules and their trapped magma to see what caused eruptions at the Las Cañadas volcanic caldera on Tenerife, in the Canary Islands. This volcano has generated at least eight major...

Indonesia Volcano Lets Out Roar Over Weekend
2012-10-08 14:49:15

Lee Rannals for redOrbit.com — Your Universe Online An active Indonesian volcano erupted once again, spewing out clouds of ash and alarming residents as far as three miles away. Mount Lokon, a 5,214-feet volcano on northeast Sulawesi island, has been very active recently, and on Sunday it added another eruption to its track record. Since its biggest eruption in July 2011, when over 5,200 people were evacuated, Mount Lokon has erupted and spewed clouds of ash about 600 times....

Mount Nyiragongo
2014-08-28 11:22:30

Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...

Nevado del Ruiz, also known as La Mesa de Herveo, is an active stratovolcano that is located along the border of the Colombian territories, or departments, of Caldas and Tolima. It reaches an elevation of 17,457 and is shaped like a cone. This volcano is protected within Los Nevados National Natural Park, along with many other volcanoes, and it is a popular tourist destination. Winter activities like skiing are conducted here as well as hiking and fishing. Nevado del Ruiz is part of the...

Galeras
2014-08-28 10:56:28

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...

Villarrica
2014-08-19 11:03:54

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...
