Mapping the chemistry of the Earth's mantle
Mapping the chemistry of the Earth’s mantle
The Earth's mantle makes up about 85% of the Earth's volume and is made of solid rock. But what rock types is the mantle exactly made of, and how are they distributed throughout the mantle? An international team of researchers - including UT researcher Dr Juan Carlos Afonso (Faculty of ITC) - have been able to reveal the existence of pockets of rocks with abnormal properties that suggest that they were once created at the surface, transported to vast depths along subduction zones, and accumulated at specific depths inside the Earth's mantle.

NASA's Webb Reveals an Exoplanet Atmosphere as Never Seen Before
NASA’s Webb Reveals an Exoplanet Atmosphere as Never Seen Before
NASA's James Webb Space Telescope just scored another first: a molecular and chemical profile of a distant world's skies. This is shown in five new articles by an international team of scientists, including Jean-Michel Désert, Hinna Shivkumar and Saugata Barat from the University of Amsterdam are soon to be published in leading science magazines.

A navigation system with 10 centimeter accuracy
Researchers of Delft University of Technology, Vrije Universiteit Amsterdam and VSL have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy of 10 centimeter.

The distance to the Moon and the length of the day 2.46 billion years ago
The distance to the Moon and the length of the day 2.46 billion years ago
At a slow pace, the Moon is moving away from the Earth and the Earth is rotating more slowly around its axis. To say something about these changes in the distant past, geologists use information stored in rocks and fossils. But the further back in time they look, the more difficult it becomes to retrieve this information.

Astronomers detect hot gas bubble swirling around the Milky Way's supermassive black hole
Astronomers detect hot gas bubble swirling around the Milky Way’s supermassive black hole
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. The research was led by Maciek Wielgus of the Max Planck Institute for Radio Astronomy in Bonn, Germany.

Explosive neutron star merger captured for the first time in millimeter light
Explosive neutron star merger captured for the first time in millimeter light
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)- an international observatory co-operated by the US National Science Foundation's National Radio Astronomy Observatory (NRAO)- have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star.
