Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

This train can travel an astounding 46 hours before needing to charge.

A famous radio signal from space long considered as a possible sign of another civilization, in the end, falls flat.

We can now report success in observing this line. A micro-wave radiometer ... field (involving spontaneous emission) and exchange with gas-kinetic energy of the hydrogen atoms (via H-H collisions ...

A super powerful space laser could be the source of a mysterious signal that has puzzled astronomers for nearly 50 years.

A commuter train that emits only water vapor will start carrying SoCal passengers in early 2025. State officials have already ...

Astronomers have long imagined that a good part of the radio spectrum to search is around 1411 to 1419 MHz, close to the 1420 ...

That’s because this new, 390-foot-long superyacht (designed by RWD with owner’s representation by Edmiston) can provide carbon-emission-free power from hydrogen ... the bottom line is that ...

By using readily available natural gas as the feedstock, C-Zero hopes to produce emission-free hydrogen for less than other green hydrogen startups, which typically rely on expensive electrolyzers ...

Hydrogen fuel cells are the latest focus of BMW in its quest to achieve zero emissions for its clean energy fleet, and it introduced its latest efforts which would see fruition come 2028.
