‘Fossils’ of galaxies reveal the formation and evolution of massive galaxies

An international team led by researchers at Swiss Federal Institute of Technology in Zürich observed massive dead galaxies in the universe 4 billion years after the Big Bang with the Subaru Telescope's Multi-Object InfraRed Camera and Spectrograph (MOIRCS).

Globally unique double crater identified in Sweden

Researchers at the University of Gothenburg have found traces of two enormous meteorite impacts in the Swedish county of Jämtland, a twin strike that occurred around 460 million years ago.

scientists think ‘planetary pebbles’ were the building blocks for the largest planets

Researchers at Southwest Research Institute (SwRI) and Queen's University in Canada have unraveled the mystery of how Jupiter and Saturn likely formed. This discovery, which changes our view of how all planets might have formed, will be published in the Aug. 20 issue of Nature.

Meteorite impacts can create DNA building blocks

A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.

First measurements taken of South Africa’s iron age magnetic field history

Earth’s magnetic shield is 500 million years older than previously thought

Since 2010, the best estimate of the age of Earth’s magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older.

Lost lithium destroyed by ancient stars

Lithium, the lightest metal, used in batteries and mood-stabilising drugs, is rarer than it should be. Models of the period after the Big Bang explain how it, hydrogen and helium were synthesised in nuclear reactions, before the universe cooled enough for the stars and planets that we see today to come into being.

Technique may reveal the age of moon rocks during spaceflight

Researchers are developing instruments and methods for measuring the ages of rocks encountered during space missions to the Moon or other planets.

Dust pillars of destruction reveal impact of cosmic wind on galaxy evolution

Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they...

Why we live on Earth and not Venus

Compared to its celestial neighbours Venus and Mars, Earth is a pretty habitable place. So how did we get so lucky? A new study sheds light on the improbable evolutionary path that enabled Earth to sustain life.

Death of a dynamo – a hard drive from space

Hidden magnetic messages contained within ancient meteorites are providing a unique window into the processes that shaped our solar system, and may give a sneak preview of the fate of the Earth’s core as it continues to freeze.

The Jacobean space programme

The 17th century saw unprecedented changes in our understanding of the universe.
