Study uncovers new evidence supporting Younger Dryas Impact Hypothesis

The Younger Dryas Impact Hypothesis (YDIH) proposes that a cometary or meteoric body exploded over the North American area sometime around 12,900-years-ago.

Moon may have influenced Stonehenge construction

A study by a team of archaeoastronomers are investigating the possible connection of the moon in influencing the Stonehenge builders.

The Alaca Höyük meteoric dagger

The Alaca Höyük meteoric dagger is an iron forged dagger with extraterrestrial origins.

Ancient celestial map found at Castelliere di Rupinpiccolo

Castelliere di Rupinpiccolo is an ancient hillfort, located in the Province of Trieste, Italy.

Possible traces of protoplanet found in Earth’s mantle

In a study of the Earth’s mantle, scientists have identified two compositionally distinct continent-sized anomalies which could be traces of a protoplanet which impacted with Earth during its early formation.

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.

Inside the Ice Giants of Space

A new theoretical method paves the way to modelling the interior of the ice giants Uranus and Neptune, thanks to computer simulations on the water contained within them.

Ring-like Structure on Ganymede May Have Been Caused by a Violent Impact

Researchers from Kobe University and the National Institute of Technology, Oshima College have conducted a detailed reanalysis of image data from Voyager 1, 2 and Galileo spacecraft in order to investigate the orientation and distribution of the ancient tectonic troughs found on Jupiter’s moon Ganymede.

Tracing Evolution From Embryo to Baby Star

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state.

A New Look at Mars’ Eerie, Ultraviolet Nighttime Glow

Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet's sky: a soft glow created by chemical reactions occurring tens of miles above the surface.

Global Magnetic Field of the Solar Corona Measured for the First Time

An international team of solar physicists, including academics from Northumbria University, in Newcastle upon Tyne, has recently measured the global magnetic field of the outer most layer of the Sun’s atmosphere, the solar corona, for the first time.

NASA Data Helps Uncover Our Solar System’s Shape

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.

Ammonia Sparks Unexpected, Exotic Lightning on Jupiter

NASA's Juno spacecraft - orbiting and closely observing the planet Jupiter - has unexpectedly discovered lightning in the planet's upper atmosphere, according to a multi-institutional study led by the NASA/Jet Propulsion Laboratory (JPL), which includes two Cornell University researchers.

Lava Tubes on Mars and Moon Wide Enough to Host Planetary Bases

The international journal Earth-Science Reviews published a paper offering an overview of the lava tubes (pyroducts) on Earth, eventually providing an estimate of the (greater) size of their lunar and Martian counterparts.

Early Mars Was Covered in Ice Sheets, Not Flowing Rivers

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously though.
