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.

The Moon is 40 million years older than previously thought

According to the giant-impact hypothesis (also known as the Theia Impact), the moon was formed when a giant object such as a protoplanet crashed into the Earth when the solar system was still young.

Scientists solve solar secret

The further we move away from a heat source, the cooler the air gets. Bizarrely, the same can’t be said for the Sun, but University of Otago scientists may have just explained a key part of why.

Death spiral: a black hole spins on its side

Researchers from the University of Turku, Finland, found that the axis of rotation of a black hole in a binary system is tilted more than 40 degrees relative to the axis of stellar orbit. The finding challenges current theoretical models of black hole formation.

Cosmic cataclysm may have caused downfall of the Hopewell Culture

Researchers from the University of Cincinnati have found evidence of a cosmic cataclysm 1,500 years that may be responsible for the downfall of the...

Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust.

Scientists from the University of Cambridge and the Ecole normale supérieure de Lyon, have proposed a new model of crystallisation where crystals remained suspended in liquid magma over hundreds of millions of years as the lunar ‘slush’ froze and solidified. 

Study pinpoints timing of Chicxulub asteroid impact

Groundbreaking study confirms time of year when asteroid wiped out dinosaurs and 75 percent of life on Earth. A groundbreaking study led by researchers at...

Fiery dragon’s breath may scorch young planets

A research group led by Kosuke Namekata and Hiroyuki Maehara at the National Astronomical Observatory of Japan (NAOJ) has been monitoring EK Draconis, a young solar-type star located 111 light-years away in the constellation Draco, the Dragon.

Map of Earth’s Asteroid and Meteor Impact Craters

Impact craters are caused when the planet is struck by solid objects travelling at high velocity, producing shock waves and the compression of material to form a circular crater.

Space Archaeology study: life & culture on the International Space Station

In an out of this world study, space archaeologists are reconstructing life on the International Space Station (ISS) over the past two decades, to better understand space culture and get an inside look at how astronauts interact with their tools and colleagues when above Earth.

Ancient meteorite found in England could reveal the origins of life on Earth

A 4.6-billion-year-old meteorite found in a field in Gloucestershire, England, is likely a remnant of cosmic debris left over from the birth of the solar system and could answer questions about how life began on Earth.

Comet strike may have sparked key shift in human civilization

A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilisation, research suggests.

New evidence of how and when the Milky Way came together

New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy.

Black Hole Pairs Found in Distant Merging Galaxies

Astronomers have found two close pairs of quasars in the distant Universe. Follow-up observations with Gemini North spectroscopically resolved one of the distant quasar pairs, after their discovery with the Hubble Space Telescope and Gaia spacecraft.

Rocky Planet Discovered in Virgo Constellation Could Change Search For Life in Universe

A newly discovered planet could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows.

Astronomers Accurately Measure the Temperature of Red Supergiant Stars

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.

The Search For Second Earth

In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward.
