Earth’s vibrational "hum" - frequencies at which our planet naturally vibrates measured

Scientists have long known earthquakes can cause the Earth to vibrate for extended periods of time. However, in 1998 a research team found the Earth also constantly generates a low-frequency vibrational signal in the absence of earthquakes. Since then, seismologists...

Unearthing the underground effects of earthquakes and volcanoes

Japanese researchers find predictive potential in underground changes associated with 2016 Kumamoto earthquake and subsequent volcanic eruptions. Most of what we know about earthquakes and volcanoes is based on what we can observe at the Earth's surface....

K2 18b

Two Super-Earths around red dwarf K2-18

New research using data collected by the European Southern Observatory (ESO) has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the...

Astronomer's map reveals location of mysterious fast-moving gas

An Australian scientist has created the most detailed map ever of clouds of high-velocity gas in the Universe around us. The map covers the entire sky and shows curious clouds of neutral hydrogen gas that are moving at a different speed to the normal rotation of the...

Earthquakes in Himalaya bigger because tectonic plates collide faster

Earthquakes that happen in densely populated mountainous regions, such as the Himalaya, spell bigger earthquakes because of a fast tectonic-plate collision, according to a new study in Earth and Planetary Science Letters. Researchers from Geophysical Fluid Dynamics...

Quantum internet goes hybrid

Researchers at the Institute of Photonic Sciences made the first demonstration of an elementary link of a hybrid quantum information network, using a cold atomic cloud and a doped crystal as quantum nodes and single photons as information carriers. In a recent...

The most tightly coupled pair of supermassive black holes ever seen

An intriguing source has been discovered in the nearby Andromeda galaxy using data from NASA's Chandra X-ray Observatory and ground-based optical telescopes. Previously thought to be part of the Milky Way's neighbor galaxy, the new research shows this source...

When magma prevents volcanic eruptions

Why does the floor of calderas lift disproportionately without erupting? Researchers from UNIGE and Roma Tre used thermal and experimental models to explain one of the least-understood processes in volcanology: 'Caldera resurgence' A spectacular proof of our...

phytoplankton boom

Southern Ocean drives massive bloom of tiny phytoplankton

Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 % of the global ocean. Known as the Great Calcite Belt, this dense group of a microscopic phytoplankton, coccolithophores, can be seen in satellite images...

Mass of warm rock is rising beneath New England

Slowly but steadily, an enormous mass of warm rock is rising beneath part of New England, although a major volcanic eruption isn't likely for millions of years, a Rutgers University-led study suggests. The research is groundbreaking in its scope and challenges...

North Texas earthquakes occurring on faults not active for 300 million years

Study by Beatrice Magnani, USGS and other SMU scientists shows recent seismicity in Fort Worth Basin occurred on faults not active for 300 million years. The study indicates reactivation of long-dormant faults as a consequence of waste fluid injection. Recent...

Parkfield segment of San Andreas fault can host large earthquakes

Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of...

High-latitude volcanic eruptions also have global impact

Volcanic eruptions always seize the attention of climate scientists, because the sulfate aerosols formed in the volcanic plumes may stay months to years in the stratosphere - the second layer of the Earth's atmosphere - resulting in the increase of radiation...

Unexpected atmospheric vortex behavior on Saturn’s moon Titan

A new study, led by a University of Bristol earth scientist, has shown that recently reported unexpected behavior on Titan, the largest moon of Saturn, is due to its unique atmospheric chemistry. Titan’s polar atmosphere recently experienced unexpected and...

Breakthrough in tornado short-term forecasting

When mere seconds of storm warning could mean the difference between harm or safety, two researchers with Western University ties have developed a tornado-prediction method they say could buy as much as 20 minutes more warning time. These radar-based calculations...

IceCube experiment measures Earth's ability to absorb neutrinos

For the first time, a science experiment has measured Earth's ability to absorb neutrinos - the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with...
