Study: Earth's magnetic reversal in combination with Grand Solar Minimum 42 000 years ago caused sudden, massive climate change

Around 42 000 years ago, the Earth's magnetic fields reversed, triggering sudden, major climate change, extinction events, and long-term changes in human behavior, a new study shows. Authors said they have precisely characterized the geomagnetic reversal and...

Research suggests water is naturally occurring on all rocky planets

A new study published recently in Science Advances suggests that water may be naturally occurring on planets and does not require an external source like water-rich asteroids. The study turns the current theory about the emergence of water upside down. The research...

Study identifies second alignment plane of solar system

According to a new study published in The Astronomical Journal, comet motions indicate that the solar system has a second alignment plane. The discovery has significant implications for models of how comets originally formed in the solar system. The study, led by...

Scientists find 'domino-like' sequence of ruptures in Ridgecrest Earthquake Sequence, California

A new study of the Ridgecrest Earthquake Sequence, the largest earthquake sequence in Southern California, that began on July 4, 2019, provided new evidence that massive earthquakes can happen in a more complex fashion than commonly expected. The observation by...

Study links big earthquakes to Earth-Moon-Sun alignments

In a new study published in Nature Geoscience yesterday, Japanese researchers have found that many of the largest earthquakes occurred near the time of maximum tidal strain — or during new and full moons when the Sun, Moon, and Earth align. The possibility...

Earth's magnetic field showing signs of significant weakening

​The first set of high-resolution results from ESA’s three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects us from cosmic radiation and charged particles that bombard Earth. Magnetic field is in a permanent...
