Scientists proposed new type of planetary object

Space
In a new study. scientists have confirmed the existence of a new, huge, spinning, donut-shaped mass of hot, vaporized rock, formed as a planet-sized...

Earth is a less volatile version of the Sun, study

Space
A recent study by the ANU scientists has found that Earth is made from the same elements as the Sun, but has less of...
An image of Saturn's moon Enceladus backlit by the Sun, taken by the Cassini mission. The false color tail shows jets of icy particles and water that spray into space from an ocean that lies deep below the moon's icy surface. Future missions could search for the ingredients for life in an ocean on an icy moon like Enceladus. Credits: NASA/JPL/Space Science Institute

Study reproduces origins of life on ocean floor

Science
Since years, scientists believe that life originated in the oceans, as the primary divisions and the events of evolution took place there. Now, NASA...
A new study uses CubeSats to measure short-term changes in northern hemisphere lakes. The study region includes (clockwise starting at the top left): Mackenzie River Delta, Northwest Territories, Canada; Canadian Shield, north of Yellowknife, Northwest Territories, Canada; Yukon Flats, Alaska and Tuktoytaktuk Peninsula, Northwest Territories, Canada.

Tiny satellites reveal water dynamics in thousands of northern lakes

Environment
Scientists at the Brown University used an army of small satellites and have shown that water levels in small lakes across northern Canada and...

Research finds billion-year superocean cycles in Earth’s history

Science
According to Curtin scientists, ancient supercontinents framed and after that went into alternating cycles traversing hundreds of millions of years that included superoceans being gulped...

Earth’s oldest rock found on the Moon

Space
Scientists may have just found the oldest intact Earth rock—on the moon. Scientists have discovered the rock decades ago by the Apollo 14 crew. The Apollo...
Rice University petrologists have found Earth most likely received the bulk of its carbon, nitrogen and other life-essential volatile elements from the planetary collision that created the moon more than 4.4 billion years ago. (Image courtesy of Rice University)

Planetary collision that formed the moon made life possible on Earth

Space
A new study by the Rice University scientists suggests that most of the Earth's essential elements of life such as carbon, nitrogen and other life-essential...
Comet 46P/Wirtanen will be making a close pass of Earth December 16, 2018. It will be at its closest distance to Earth in over four centuries. It is a member of the Jupiter family of comets - their farthest point from the sun being near the orbit of Jupiter. It will be bright enough to see with the naked eye above the eastern horizon all month long, and can be seen even better with a telescope and/or binoculars. This 120 second image of the comet was taken Dec. 2 by an iTelescope 50 mm refractor located at an observatory near Mayhill, New Mexico. The streak below the comet was produced by a rocket body (upper stage) passing through the telescope's field of view during the exposure. Specifically, the upper stage is the one that placed the Indonesian Garuda 1 communications satellite into geostationary orbit back in February of 2000. At the time of this image, the Garuda 1 upper stage was 15,880 miles from the observatory; Comet Wirtanen was 10.3 million miles distant. Image Credit: NASA

The brightest comet of the year will be visible this Sunday

Space
On Sunday, Dec. 16, the comet named 46P/Wirtanen will make its 10 closest comet flybys of Earth in 70 years. And as scientists reported, you...
This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.

Global warming wiped out 95% of marine life 252 million years ago

Environment
A new study by the University of Washington has suggested that extreme global warming caused Earth's biggest ever mass extinction. The largest extinction in Earth's history...
