Super-dense packing of hydrogen molecules on a surface

Hydrogen (H2) is currently discussed as an ideal energy carrier of renewable energies. Hydrogen has the highest gravimetric energy density of all chemical fuels (141 MJ/kg), which is three times higher than gasoline (46 MJ/kg). ...

Astronomers discover sunscreen snow falling on hot exoplanet

Astronomers at Penn State have used the Hubble Space Telescope to find a blistering-hot giant planet outside our solar system where the atmosphere "snows" titanium oxide. These Hubble observations are the first detections ...

Is K2-18b covered in oceans of water or oceans of lava?

In the search for potentially life-supporting exoplanets, liquid water is the key indicator. Life on Earth requires liquid water, and scientists strongly believe the same is true elsewhere. But from a great distance, it's ...

Satellite research reveals smaller volcanoes could cool climate

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can ...

CU-Boulder to build $6 million instrument for NASA lunar orbiter

The University of Colorado at Boulder has been awarded a $6 million grant from NASA to build a high-tech lunar dust detector for a 2011 mission to orbit the moon and conduct science investigations of the dusty lunar surface ...

NASA study traces decade of ammonia air pollution in Africa

A new NASA-led study is the first to document changing atmospheric ammonia (NH3) concentrations in Africa over an extended period. Ammonia is an air pollutant which can lead to heart and lung related illness. When present ...
