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...

volcanic eruptions cooled the earth aug 7 2020

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...

Scientists resolve origin of oddball meteorites with X-rays

Scientists at the Lawrence Berkeley National Laboratory conducted X-ray experiments to resolve the origin of rare, odd meteorites that have puzzled many researchers since they were discovered about 50 years ago. Also known as Type IIE iron meteorites, these objects...

Most detailed seafloor depth map of Arctic Ocean released

An international team of researchers released the most detailed seafloor depth map of the Arctic Ocean. The map, which is the 4.0 version of the International Bathymetric Chart of the Arctic Ocean (IBCAO), expands up to 19.6 percent of the submarine surface mapped...

New method helps predict big solar flares

Scientists developed a new physics-based technique that successfully predicted seven of the Sun's largest flares from the past solar cycle, out of a set of nine. With further improvement, the new model could be used to inform forecasters of these intense...

Research offers new clues about where and how subduction starts on Earth

An international team of researchers published a new study providing new clues about how and where subduction begins on Earth, the process behind the deadliest volcanic eruptions. The Earth's largest earthquakes and most explosive volcanoes occur at subduction...

Extremely elongated cloud returns over Arsia Mons volcano, Mars

The Visual Monitoring Camera (VMC) attached to Mars Express captured a mysteriously long, thin cloud over the 20 km (12 miles) high Arsia Mons volcano on July 17 and 19, 2020. According to ESA, the cloud is a recurrent feature made up of water ice and is influenced...

Snowball Earth events linked to drastic drop in Sun's radiation

Scientists from the Massachusetts Institute of Technology (MIT) suggest that Snowball Earth-- a hypothesis proposing that the planet's surface became entirely frozen at least twice 700 million years ago-- might be linked to dramatic plunges in the amount of...

Hurricane "Lane" caused first known case of both heavy rainfall and multiple instances of fire simultaneously

A recent study by the University of Hawaii examined the impacts of the 2018 Hurricane "Lane" and revealed that preceding moisture conditions brought by the storm exacerbated fire hazards, and both fire and rain severity were impacted by the hurricane...

Deep recurring earthquakes detected beneath dormant Mauna Kea volcano, Hawaii

USGS seismologists have detected deep long-period earthquakes beneath the dormant Mauna Kea volcano in Hawaii at depths of about 20 to 25 km (12 to 15 miles) occurring with surprising regularity every 7 to 12 minutes. While low-frequency earthquakes are not unusual,...

Study reveals South Atlantic magnetic anomaly is a recurring feature

In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly...
