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.

Cosmic radio burst offers path to weigh the Universe

In an article published in the latest issue of Science, Dr. Stuart Ryder from Macquarie University and Associate Professor Ryan Shannon from Swinburne University of Technology, leading a global team, have unveiled their groundbreaking discovery: the oldest and most distant fast radio burst ever detected, dating back approximately eight billion years.

The Maya predicted annular solar eclipses

On October 14th, 2023, a celestial event will unfold as the Sun, Moon, and Earth, align to create an annular solar eclipse.

Study reveals new secrets of the Maya calendar

A team of anthropologists from Tulane University have deciphered new secrets of the Maya calendar.

Meteorite crater found in Southern France

Researchers from Goethe University Frankfurt have found a meteorite crater in the grounds of a winery near the town of Béziers in Southern France.

Researchers discover earth sized planet

Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.

Origins of the Mesoamerican astronomy and calendar from the Olmec and Maya regions

In a paper published in the journal, Science Advances, researchers have applied archaeoastronomical studies to demonstrate how the civic and ceremonial buildings in Mesoamerica were largely oriented to sunrises or sunsets on specific dates from the Olmec and Maya regions

Filmmakers discover large fragment from Challenger space shuttle

A documentary film crew have discovered a large fragment from the Challenger space shuttle, while searching for the wreck of a WW2 aircraft off the Florida coast, United States.

Tree rings reveal devastating radiation storms

A study by the University of Queensland has revealed new insights into the cosmic radiation storms that have occurred approximately once every thousand years.

Impact that killed the dinosaurs triggered “mega-earthquake”

66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs.

Potential first traces of the universe’s earliest stars

Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe.

Byzantine solar eclipse records illuminate obscure history of Earth’s rotation

Japanese researchers investigated ancient texts from the 4th to 7th centuries AD to identify five total solar eclipses near the Eastern Mediterranean and improve the model of the Earth's rotation over time

Astronomers have discovered an exoplanet that could be completely covered in water

An international team of researchers led by Charles Cadieux, a Ph.D. student at the Université de Montréal and member of the Institute for Research on Exoplanets (iREx), has announced the discovery of TOI-1452 b, an exoplanet orbiting one of two small stars in a binary system located in the Draco constellation about 100 light-years from Earth.

Underwater snow gives clues about Europa’s icy shell

Below Europa’s thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines.

Telescope reveals images of supermassive black hole at centre of galaxy

Astronomers have revealed images of a supermassive black hole at the centre of the Milky Way galaxy using the Event Horizon Telescope (EHT), a telescope array consisting of a global network of radio telescopes.

Researchers open lunar time capsule from Apollo 17 mission

Scientists from NASA have opened a lunar time capsule from the Apollo 17 mission conducted in 1972.

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.
