Due to the difficult accessibility and the high risk of collapse or explosion, the imaging of active volcanoes has so far been a great challenge in volcanology.
Researchers around Edgar Zorn from the German Research Centre for Geosciences GFZ in…

Higher Sea Level Rise Predicted by Melting Ice Sheets
A new study by the Nanyang Technological University has been studying melting polar ice sheets and predicts that ocean levels will rise by as much as 1.3 metres by 2100.
The new study makes sea-level rise projections which are significantly…

The lower mantle can be oxidized in the presence of water
If we took a journey from Earth’s surface to the center, the midway point locates roughly at 1900 km depth in the lower mantle.
The lower mantle ranges from 660 to 2900 km depth and occupies 55% of our planet by volume. The chemical composition…

ALMA spots twinkling heart of Milky Way
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*.
The team interpreted these blinks to be due to the rotation of…

ALMA discovers massive rotating disk in early universe, nicknamed the Wolfe Disk
In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late.
But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk…

Telescope reveals signs of star being born
The European Southern Observatory has revealed signs of the birth of a star system.
Around the young star AB Aurigae lies a dense disc of dust and gas in which astronomers have spotted a prominent spiral structure with a ‘twist’ that marks the…

Bayesian statistics applied to shed light on how extraterrestrial life might evolve on other planets
We know from the geological record that life started relatively quickly, as soon our planet’s environment was stable enough to support it.
We also know that the first multicellular organism, which eventually produced today’s technological…

The story of Earth’s evolution is being deciphered
Around 1800 miles beneath the Earth’s surfaces is a magmatic region between the solid silicate-based mantle and molten iron-rich core: The core-mantle boundary.
It’s a remnant of olden times, the primordial days about 4.5 billion years ago…

Mars – The planet where mud erupts and flows
Mars today has no active volcanoes, much of the heat stored inside the planet has been lost over millions of years creating a thick outer crust preventing molten rock reaching the surface.
A study today of the planet’s surface shows possible…

‘Hot and messy’ entanglement of 15 trillion atoms
Quantum entanglement is a process by which microscopic objects like electrons or atoms lose their individuality to become better coordinated with each other.
Entanglement is at the heart of quantum technologies that promise large advances in…
