Magnitude 6.9 earthquake strikes Mariana Islands region in the Pacific

A magnitude 6.9 earthquake has struck near the Northern Mariana Islands in the Pacific, according to an announcement from the US Geological Survey. The earthquake...

Life might be easiest to find on planets that match an earlier Earth

We're inching closer and closer to reliably detecting biosignatures on distant planets. Much of the focus is on determining which chemicals indicate life's presence. But...

An asteroid came uncomfortably close to Earth in July. Could we have stopped it?

In July of this year, an asteroid roughly 30 to 60 meters across passed Earth to within one-quarter of the distance to the moon....

Venus had Earth-like plate tectonics billions of years ago, study suggests

Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred...

Minerals in ancient meteorites offer insights into the origin of most of the Earth’s surface

Dr. Alice Stephant, an astrophysicist, is helping to solve a longstanding mystery about water on Earth: where it came from. Scientists long thought that water,...

Iron atoms discovered on the move in Earth’s solid inner core

The iron atoms that make up the Earth's solid inner core are tightly jammed together by astronomically high pressures—the highest on the planet. But even...

Ascertaining distances for supernovae that struck the Earth 3 million and 7 million years ago

A study, released on the pre-print server arXiv, examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that...

NASA readies for dramatic return of asteroid sample to Earth

The climactic end of a seven-year voyage comes Sunday when a NASA capsule is due to land in the Utah desert, carrying to Earth...

Largest asteroid sample ever collected is coming down to Earth

Chunks of asteroid that could tell us about the earliest days of the 4.5 billion-year-old solar system and the possible origins of water on...

Venus on Earth: NASA’s VERITAS science team studies volcanic Iceland

With its crushing atmospheric pressure, clouds of sulfuric acid, and searing surface temperature, Venus is an especially challenging place to study. But scientists know...

An ambitious new technology might be needed to see other Earths

The race is on to discover truly habitable Earth-like worlds. While we are starting to observe the atmospheres of large potentially habitable planets such...

Earth’s crust, tectonic plates gradually formed, geoscientists find

The Earth's crust continued a slow process of reworking for billions of years, rather than rapidly slowing its growth some 3 billion years ago,...
