Field Geology at Mars’ Equator Points to Ancient Megaflood

Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago - a finding that hints at the possibility that life may have existed there, according to data collected by NASA's Curiosity rover and analyzed in joint project by scientists from Jackson State University, Cornell University, the Jet Propulsion Laboratory and the University of Hawaii.

The Milky Way Galaxy has a Clumpy Halo

University of Iowa astronomers have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars.

Magnetic Fields on the Moon are the Remnant of an Ancient Core Dynamo

Presently, the moon does not have an internal magnetic field as it can be observed on Earth. However, there are localized regions on its surface up to several hundred kilometers in size where a very strong magnetic field prevails.

Geoscience: Cosmic Diamonds Formed During Gigantic Planetary Collisions

It is estimated that over 10 million asteroids are circling the Earth in the asteroid belt. They are relics from the early days of our solar system, when our planets formed out of a large cloud of gas and dust rotating around the sun.

Remnants Ancient Asteroid Shed New Light on the Early Solar System

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system.

Venus’ Ancient Layered, Folded Rocks Point to Volcanic Origin

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.

Meteorite Strikes May Create Unexpected Form of Silica

When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site?

Spinning Black Hole Powers Jet by Magnetic Flux

Black holes are at the center of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light.

Sustained Planetwide Storms May Have Filled Lakes and Rivers on Ancient Mars

A new study from The University of Texas at Austin is helping scientists piece together the ancient climate of Mars by revealing how much rainfall and snowmelt filled its lake beds and river valleys 3.5 billion to 4 billion years ago.

Discovery Lays Blame on Supernova for Extinction Event Nearly 360 Million Years Ago

Between a decline in biodiversity and a series of extinction events, the Late Devonian period was not the most hospitable time on Earth.

How Stars Form in the Smallest Galaxies

The question of how small, dwarf galaxies have sustained the formation of new stars over the course of the Universe has long confounded the world's astronomers.

Academics Develop New Method to Determine the Origin of Stardust in Meteorites

Meteorites are critical to understanding the beginning of our solar system and how it has evolved over time.
