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 […]

Two new studies about Mars made news this week. Liquid Water Lake Detected on Mars First, a group of Italian scientists announced that they detected a 20-kilometer-wide lake of liquid water located about 1.5 kilometers beneath the ice of the southern polar ice cap of Mars. The scientists analyzed more than three years of data […]

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 […]

Hot Monster Planet; No Fountain of Youth; Sunscreen Snow on Exoplanet

November 3, 2017

Hot Monster Planet Found Orbiting Small Star British astronomers say they discovered a “monster” planet orbiting a tiny star, but, according to planet formation theory, the planet should not even exist. The theory suggests a planet of its size could not be formed around such a small star. Located about 600 light years from Earth, […]
