NASA showcases amazing images of gullies formed at Matara Crater on Mars

NASA's Mars Reconnaissance Orbiter (MRO) has sent amazing images of Matara Crater on the Red Planet. The high resolution images showcase many gullies that run through the sand dunes in the Matara Crater region. As per NASA release earlier this week, gullies on Mars are different from those seen on Earth. The gullies on Mars are created by ‘freeze and thaw of carbon dioxide frost’.

Ancient Oceans on Mars Could Have Formed After Massive Volcanic Eruptions: Research

Ancient Oceans on Mars Could Have Formed After Massive Volcanic Eruptions: Research

The shallow oceans on Mars could have formed due to massive volcanic eruptions on the Red Planet in the past, suggests a new research paper released by University of California, Berkeley researchers. Scientists suggest that shoreline-like structures on Mars could have been formed due to shallow oceans but there wasn’t an easy explanation about where the water disappeared. The research paper published in the journal Nature also points that massive volcanic eruptions could have changed the climate to such an extent that water couldn’t exist in liquid form.

Sierra Nevada Mountain Range registered 24 mm rise during drought years

Sierra Nevada Mountain Range registered 24 mm rise during drought years

Sierra Nevada mountain range in California witnessed a rise by 24 millimeters (one inch approximately) during the drought years in the state. A research conducted recently has noticed that the rise was witnessed between October 2011 and October 2015. The study conducted by NASA’s Jet Propulsion Laboratory scientists added that the natural phenomenon occurred due to loss of water from the Sierra Nevada mountain range. The study team evaluated data from 1,300 sensors placed at different locations in the mountain range in California, Oregon and Washington.

Yellowstone Supervolcano could erupt explode earlier than previous estimates

Yellowstone Supervolcano could erupt explode earlier than previous estimates

The Yellowstone super volcano could erupt much earlier compared to previous estimates, as per a new research team from Arizona State University working in the region in and around the Yellowstone National Park. The supervolcano has been analyzed by many research teams and independent volcanologists in the past. The Yellowstone supervolcano region has a massive magma reservoir. A study conducted in 2011 found that the region above the magma reservoir in Yellowstone has bulged up by 10 inches in seven years.

Massive wildfire blazing in Greenland

Massive wildfire blazing in Greenland

Scientists have spotted a massive wildfire raging across western Greenland, a region better known for thick ice and snow, NASA’s Earth Observatory confirmed.

Using satellite images, scientists spotted a “sizable fire” raging nearly 90 miles or 150 km northeast of the town of Sisimiut. It was first spotted on 31st of July.

Moon’s interior may contain water: Study

Moon’s interior may contain water: Study

A new study of ancient volcanic deposits on the Moon has suggested that earth’s only natural satellite might be containing substantial amounts of water deep under its surface.

A team of researchers from Brown University examined lunar pyroclastic deposits using satellite data. Pyroclastic deposits are layers of rock formed from massive volcanic eruptions. Magma associated with these explosive events came from very deep within the Moon’s interior.

Massive Iceberg breaks loose in Antarctic region

Massive Iceberg breaks loose in Antarctic region

After several months of widening of the rift, one of the largest ever recorded icebergs has finally broken away from Antarctica, scientists announced on Wednesday.

Scientists who have been monitoring the widening rift in the West Antarctic ice shelf for the last many years said that the calving of the 5,800 sq. km. iceberg has left the Larsen C Ice Shelf with 12 percent decline in area.

The iceberg in question is one of the largest recorded and its progress in the near future remains difficult to predict.

Volcanologists Reveal Interesting Information After Analyzing Crystals Deep Inside a Volcano

Volcanologists Reveal Interesting Information After Analyzing Crystals Deep Inside a Volcano

After checking crystals once deep inside a volcano, researchers are confident that they can better predict many factors that are linked to timing of eruption of a volcano. Volcanologists worked on an interesting project have published a research paper in journal Science after checking magma reservoir that lies below New Zealand's Mount Tarawera volcano. The research team added that before its eruption, a volcano offers many signals and it will be important to decipher those signals if we have to improve our prediction about volcanic eruptions.

Scientists discover new energy source in New Zealand

Scientists discover new energy source in New Zealand

A team of scientists drilled deep into an earthquake fault in New Zealand, and stumbled upon something that could provide a new source of energy for the South Pacific nation.

Led by Victoria University of Wellington’s Professor Rupert Sutherland, the scientists were surprised to find that water in the Alpine Fault was much hotter than their expectation. They concluded that it could be harnessed to generate electricity or to provide industries like dairy farming with direct heating.

Remote Island found littered with plastic debris

Remote Island found littered with plastic debris

A new study by a team of Australian and British researchers has revealed that a remote, uninhabited island in the South Pacific has the world’s worst plastic rubbish density.

The researchers found an estimated 37.7 million pieces of rubbish on the beaches of Henderson Island, which is part of the United Kingdom’s Pitcairn Islands group.
