Congestion in the Earth's mantle
Seismic measurements show that in some regions of the Earth's mantle, plate tectonics stagnates. The causes of the 'congestion' of the subducted plate are still unknown. In the current issue of the science magazine Nature Geoscience mineralogists from Germany explain the phenomenon for the first time. (2013-03-31)

New model explains the moon's weird orbit
A new research paper suggests that the impact that formed the moon also sent the Earth spinning much faster, and at a much steeper tilt, than it does today. In the several billion years since that impact, complex interactions between the Earth, moon and sun have resulted in the Earth-moon system that we see today. In this scenario, the remaining anomalies in the moon's orbit are relics of an explosive past. (2016-10-31)

EARTH: Do-it-yourself lava flows
It's not every day that lava flows through a college campus parking lot. But, since January 2010, Syracuse University has been bringing the lava to Central New York. Using commercially available basalt gravel and a coke-fired furnace, the geologists involved with the Syracuse University Lava Project are able to produce a wide range of flow morphologies and other features at a scale comparable to natural flows.

Transit search finds Super-Neptune
Astronomers at the Harvard-Smithsonian Center for Astrophysics have discovered a planet somewhat larger and more massive than Neptune orbiting a star 120 light-years from Earth. While Neptune has a diameter 3.8 times that of Earth and a mass 17 times Earth's, the new world (named HAT-P-11b) is 4.7 times the size of Earth and has 25 Earth masses. (2009-01-20)

Sun sends out a significant solar flare
The sun emitted a significant solar flare, peaking at 5:12 p.m. EST on Nov. 5, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

3-D Simulation Predicts Earth's Coronal Mass Ejections
New ultra-high speed computer software can simulate the effects of solar surface eruptions on the Earth's magnetosphere. 3-D models of eruptions are created far faster than real time---meaning the simulation might some day predict the effects of space weather phenomena on Earth in ample time to prepare for them. (1997-12-11)

EARTH: US Navy navigates a sea change in the Arctic
The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism. Therefore, a more accessible Arctic not only means environmental changes, but also changes in our economy and our national security. (2012-04-17)

Climate changed in steps in the past
An international study published in Science significantly improves the potential for understanding how the Earth's climate system evolved over the past 66 million years. The work reveals that the Earth system shifted abruptly between 4 distinct modes: hothouse, warmhouse, coolhouse, and icehouse during the period. The EU Horizon 2020 TiPES project contributed to the results. (2020-09-10)

Researchers propose new way to chart the cosmos in 3-D

Oceanic crust breakthrough: Solving a magma mystery
Oceanic crust covers two-thirds of the Earth's solid surface, but scientists still don't entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust by a team including Carnegie's Frances Jenner reveals a systemic pattern that alters long-held beliefs about how this process works, explaining a crucial step in understanding Earth's geological deep processes. (2012-11-29)

Tides Recorded The Moon's Retreat From Earth, Shorter Earth Days
Layers of sediment deposited by tides show that 900 million years ago, a day on Earth was 18 hours long. The moon has been moving away from Earth at a constant rate, according to the same evidence. University of Arizona planetary scientists and collaborating geologists publish their analysis today (July 5) in Science (1996-07-05)

ICESat's lasers measure ice, clouds and land elevations
NASA's Ice, Cloud and land Elevation Satellite (ICESat) has resumed measurements of the Earth's polar ice sheets, clouds, mountains and forests with the second of its three lasers. Crisscrossing the globe at nearly 17,000 miles per hour, this new space mission is providing data with unprecedented accuracy on the critical third dimension of the Earth, its vertical characteristics. (2003-10-06)

'Lubricating' sediments were critical in making the continents move
Plate tectonics is a key geological process on Earth, shaping its surface, making it unique among the Solar System's planets. Yet, how plate tectonics emerged and which factors controlled its evolution remains controversial. Now, researchers from the German Research Centre for Geosciences GFZ, the University of Potsdam and the University of Maryland, in a study published in Nature, propose that natural lubrication by debris from surface erosion was crucial in starting and maintaining plate tectonics. (2019-06-05)

NJIT solar physicists report paradox: Less sunlight, but temps rise
Less sunlight reaching the Earth's surface has not translated into cooler temperatures, according to a team of solar physicists at New Jersey Institute of Technology. The scientists, who monitor the Earth's reflectance by measuring what is known as the moon's earthshine, have observed that the amount of light reflected by Earth -- its albedo -- has increased since 2000. The result has been less sunlight reaching the Earth's surface. (2006-01-23)

NASA spacecraft show three-dimensional anatomy of a solar storm
Twin NASA spacecraft have provided scientists with their first view of the speed, trajectory, and three-dimensional shape of powerful explosions from the sun known as coronal mass ejections, or CMEs. This new capability will dramatically enhance scientists' ability to predict if and how these solar tsunamis could affect Earth. (2009-04-14)

Scientists expect to calculate amount of fuel inside Earth by 2025
Scientists have developed numerous models to predict how much fuel remains inside Earth to drive its engines -- and estimates vary widely -- but the true amount remains unknown. In a new paper published in Nature Scientific Reports, a team of geologists and neutrino physicists boldly claims it will be able to determine by 2025 how much nuclear fuel and radioactive power remain in the Earth's tank. (2016-09-09)
