H3+: The molecule that made the Universe

(Phys.org) -- In a study that pushed quantum mechanical theory and research capabilities to the limit, University of Arizona researchers have found a way to see the molecule that likely made the universe - or at least the ...

Observation of the hyperfine spectrum of antihydrogen

A Canadian-led investigation has opened a new chapter in antimatter research. In a study published today in Nature, the ALPHA Collaboration, which includes 50 physicists from 17 institutions, reports the first detailed observation ...

Is the universe actually shrinking?

Whoa, here's something to think about. Maybe the Universe isn't expanding at all. Maybe everything is actually just shrinking, so it looks like it's expanding. Turns out, scientists have thought of this.

Mystery of dwarf galaxy could be ejected black hole

An international team of researchers analyzing decades of observations from many facilities—including the W. M. Keck Observatory on Mauna Kea, the Pan-STARRS1 telescope on Haleakala and NASA's Swift satellite—has discovered ...

Solving the riddle of neutron stars

It has not yet been possible to measure the gravitational waves predicted by Einstein's theory of general relativity. They are so weak that they get lost in the noise of the measurements. But thanks to the latest simulations ...

Dual-color lasers could lead to cheap and efficient LED lighting

(Phys.org) —A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally ...

The cosmic chemistry that gave rise to water

Earth's water has a mysterious past stretching back to the primordial clouds of gas that birthed the Sun and other stars. By using telescopes and computer simulations to study such star nurseries, researchers can better understand ...
