The pions, in turn, will decay rapidly into very high-energy light, or gamma rays.
The High-Altitude Water Cherenkov Observatory or Hawc, high on a Mexican plain, now holds the record for the highest-energy light it can capture.
The skies are currently being flooded with the brightest display of gamma rays - the Universe's highest-energy light - ever seen by astronomers.
Responsible individuals across our country are taking action by using low-energy light bulbs, purchasing fuel-efficient and hybrid vehicles, and trying to live their own lives more sustainably.
Energy advice and two low-energy light bulbs are also available.
Astrophysicists can determine how the blazar grew brighter in different parts of the spectrum at different times and refine their models of how fast-moving particles within the jets give rise to the high-energy light.
This happened in Japan, where low-energy fluorescent light now accounts for more than 95% of residential lighting.
They need relatively small amounts of energy to light schools, run health services, increase production and create jobs.
Centaurus A is the closest of the "active galaxies", which are galaxies spewing out huge amounts of energy and light.
As the particles are absorbed by the crystals, they give up their remaining energy as light providing further information about their identity.
Supernovae are the result of the explosion of a massive star, and they release so much energy and light that they can actually be brighter than the combined light of an entire galaxy.
The energy consumption data also could help home and business owners take stock of their energy use and take actions to save money, such as putting in more energy efficient light bulbs and appliances or running washers and dryers only when electric rates are low.

When this sort of star implodes, to create a black hole, it generates jets of material that punch their way out of the collapsing mass at near light-speed, to produce extremely high-energy emissions of light.
The advance provides evidence to support a controversial idea, called multiple-exciton generation (MEG), which theorizes that it is possible for an electron that has absorbed light energy, called an exciton, to transfer that energy to more than one electron, resulting in more electricity from the same amount of absorbed light.

She radiates charm and energy and can light up any room (or computer screen).
Yet TCP is facing a new problem: technology used in energy-efficient light bulbs is changing.

Solar panels use light energy from the sun to generate electricity through the photovoltaic effect.
BBC: Bristol and Bath Science Park gets new solar roof panels
Light Energy that produces and sells solar-powered LED lanterns to replace kerosene lights in the emerging market villages.
Another local firm in Bodmin has already fitted more than 700 low energy LED (light emitting diode) lights at Eden.
To get a LEED certification, for instance, homes collect points for green features, such as energy-efficient light bulbs and water-saving toilets.
Thanks to an energy saving LED light source, the light-weight presenters offer a long battery life of up to 80 minutes.
ENGADGET: Toshiba outs Lumileo pico projectors, only one of which requires a plug
Switch to energy-saving light bulbs and smaller TVs and refrigerators, she advises.
They were bold, confident, and had an energy that could light up a room, and did every single day that we were there.
They then have nowhere to put all the light energy they are absorbing, and the resulting breakdown of biochemical pathways creates toxic oxygen-containing molecules known as free radicals.
Fluorescent and LED lights use nearly two-thirds less energy than regular light bulbs, are significantly brighter, and, according to Consumer Reports, will last nearly 50-times longer than incandescent bulbs.
Technologies on display ranged from solar powered water purification units to military vehicles using next generation materials and energy sources to light weight batteries that can give better range and endurance.
If less than 1% of MTV's potential viewers around the world switched to three energy-efficient light bulbs, it would be equivalent to taking 100, 000 cars off the road, Roedy adds, the well-rehearsed statistics rolling off his tongue.
Yes, I have energy-efficient light bulbs too.
