The new dataset introduces a seamless, annual Leaf-On Landsat composite data cube for China, spanning from 1985 to 2023.

Scientists have been able to recreate the extreme conditions found on icy moons in deep space - and revealed the unstable behaviour of water. 

- The HeH⁺ ion was the first molecule to form in the early universe, before the first stars were born.

- Researchers have investigated reactions of HeH⁺ with hydrogen atoms under conditions similar to those in the early universe for the first time, revealing significant discrepancies with previous theories.

- The results significantly impact our understanding of the early chemistry of the universe and the processes that contributed to the formation of the first stars.

An international team led by the Universities of Geneva (UNIGE) and Montreal published the first results today from the NIRPS spectrograph installed on the European Southern Observatory’s (ESO) 3.6-meter telescope in La Silla, Chile. This new instrument, which operates in the near infrared, offers exceptional performance in detecting and characterising exoplanets, particularly around red dwarfs. By combining NIRPS with the HARPS spectrograph, which operates in visible light, astronomers have access to unrivalled spectral coverage for studying exoplanets. The first five scientific papers can be found in the journal Astronomy & Astrophysics.

A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar system. 

Bridges endure constant environmental and operational stresses—some visible, others imperceptible.
