The gorgeous colors of Yellowstone National Park’s Grand Prismatic hot spring are among the park’s many hydrothermal features created by the fact that Yellowstone sits above a supervolcano – the largest type of volcano on Earth. (Robert B. Smith & Lee J. Siegel)

Possible New Power Source of Yellowstone Supervolcano Found

July 30, 2018

According to the US Geological Survey, the Yellowstone supervolcano, located in the Western United States, is known to have had three major eruptions between 640,000 and 2.1 million years ago. It’s been long thought that the volcano was powered by heat from the Earth’s core, like most other volcanoes. But, a new study suggests that […]

Volcanic Activity Created Martian Geological Oddity

June 19, 2018

Scientists have long been puzzled by a mysterious formation located near the equator of Mars called Medusae Fossae. A new study from a pair of scientists – Lujendra Ojha and Kevin Lewis – at the Johns Hopkins University in Baltimore suggests that the large deposit of soft rock was probably formed as a result of violent volcanic eruptions that […]

NASA Seeks Astronauts; Good Sleep = Good Mood; Device Finds Water in Space

November 4, 2015

Help Wanted – NASA As NASA continues to prepare to resume human spaceflight launches and readies its ambitious ‘Journey to Mars’, it is putting out its “help wanted” sign. The space agency announced that it will soon begin to accept applications for its next class of astronauts who will fly from the Space Coast of […]

Giant Magma Reservoir Found Beneath Yellowstone Supervolcano

April 23, 2015

Yellowstone National Park’s many geothermal features, including its estimated 10,000 hot springs and geysers, draw millions of visitors each year. There’s good reason why the approximately 8,983 square km park has such a high level of geothermal activity. You see, the park sits atop one of the world’s largest active volcanic systems. According to the […]

Scientists Move Closer to Predicting Volcanic Eruptions

June 12, 2012

Oregon scientists who correctly predicted the 2011 eruption of the Axial Seamount underwater volcano years before it occurred, now say another underwater volcano off the Oregon coast gave off signals just hours before it erupted. Underwater hydrophones showed a sudden increase in seismic energy about 2.6 hours before the eruption started about 400 kilometers off […]
