Study: Modern Grand Solar Minimum (2020 - 2053) leads to cooling, important implications for entire planet

In a new study published recently in the journal Temperature, Prof. Valentina Zharkova demonstrates that the Sun has entered into the modern Grand Solar Minimum (2020 - 2053) that will lead to a significant reduction of the solar magnetic field and activity like...

New equatorial wind patterns observed in Antarctica, revealing new connections in global circulation

A team of researchers found evidence of a new equatorial wind pattern at Antarctica, unveiling a crucial connection between winds at the Earth's equator and atmospheric waves about 10 000 km (6 000 miles) away at the South Pole. The findings highlight how winds...

Eruptive origins of pyroclastic deposits on the Moon

A new study by researchers from Arizona State University (ASU) suggests that the early Moon may have been more volatile-rich than previously believed. Previous studies concluded that lunar volcanoes had exploded primarily cold bedrock, but the ASU team said there...

Earth moving through radioactive remnants of supernovae for the past 33 000 years

A new study suggests that the Earth has been moving through the remnants of an ancient exploded star for at least the past 33 000 years. The research team extracted a special isotope of iron called iron-60 from sea sediment samples and found that the isotope is...

Mysterious, spiral-shaped ultraviolet light pulses over Mars

New images from NASA's MAVEN spacecraft reveal wide areas of Mars' night sky pulsing in ultraviolet light. While researchers understand the light's source, its mysterious spiral shape left them puzzled. "There is a vast spiral of ultraviolet light...

Researchers measure Earth's magnetic field in Jerusalem in 586 BCE

Researchers from Tel Aviv University, the Hebrew University of Jerusalem, and the Israel Antiquities Authority were able to measure the Earth's magnetic field in Jerusalem in 586 BCE-- the time when the city was destroyed by the Babylonians. The groundbreaking...

Our Sun started its life with a binary companion, new study suggests

A new theory published this week in the AAS' The Astrophysical Journal Letters suggests that our Sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar companion increases the likelihood that the Oort cloud was...

First high-resolution optical seismometer survives 'hellish' peak of La Grande Soufrière

A team of scientists successfully installed an optical seismometer on La Grande Soufrière volcano's summit-- the first high-resolution instrument placed on an active volcano. The seismometer, used to monitor gas and steam eruptions, survived the...

Florida Current at its weakest in the past 110 years

New research by the Woods Hole Oceanographic Institution (WHOI) found that a key component of the Gulf Stream-- a warm Atlantic ocean current stretching to the tip of Florida-- has steadily slowed and is now weaker than at any other point in the past 110 years. The...

Cosmic rays increase remarkably as solar activity shows persistent decline, resembles Dalton minimum of 1790 - 1830

Recent solar conditions indicate a persistent decline in solar activity‐‐‐possibly similar to the past solar grand minima, scientists reporting in AGU's Space Weather write. During such periods of low solar activity, the fluxes of galactic cosmic rays...

Lasers detect space debris in daylight for the first time

For the first time, scientists have used lasers to detect space debris in broad daylight. Prior to this, lasers could only be used to measure the distance to space debris during a few twilights hours. A new study proved that it is possible to use lasers in full...

Study suggests volcanic eruptions caused global cooling 13 000 years ago, not meteors

Some scientists believe that an extraterrestrial impact, such as a meteor collision, caused global cooling around 13 000 years ago. However, a new study presents evidence left in layers of sediment showing that the event was most likely caused by volcanic eruptions....

Study finds herbivores at highest risk of extinction

A new study by Utah State University (USU) suggests that modern megaherbivores-- plant-eaters that weigh more than 1 000 kg (2 200 lbs)-- have the highest risk of going extinct among mammals, birds, and reptiles, just like what happened to their prehistoric...
