Better solutions for making hydrogen may lie just at the surface

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be derived from another substance that contains ...

Hubble spots double quasars in merging galaxies

NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based ...

Dozens of ultra-compact dwarf galaxies detected

Astronomers from the University of Groningen and elsewhere have identified 44 new ultra-compact dwarf galaxies (UCDs). The newly found objects most likely belong to the Fornax Cluster. The discovery is reported in a paper ...

Space Exploration

All aboard! Next stop space...

Several hundred people have already booked their tickets and begun training for a spectacular voyage: a few minutes, or perhaps days, in the weightlessness of space.

Exploration of ocean currents beneath the 'Doomsday Glacier'

For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the "Doomsday Glacier." They find that the supply of warm water to the glacier is larger than previously thought, ...

Abrupt ice age climate changes behaved like cascading dominoes

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the ...
