Sentences with phrase «ionised gas»
"Ionized gas" refers to a type of gas where some of its atoms or molecules have gained or lost charged particles called ions. This process creates an electrically conducting gas that can produce colorful light or carry electricity more easily. Full definition
The Lancaster team used the Subaru and Keck telescopes on Hawaii, and the Very Large Telescope in Chile to discover several galaxies which seem to have large bubbles of ionised gas around them, allowing light to pass through.

Clouds of electrons created by ionised gas in the beam chamber and microscopic dust particles — playfully known as unidentified falling objects, or UFOs — are interrupting the beams and making it harder to get the LHC running consistently.
They say clouds of electrons created by ionised gas in the beam chamber and microscopic dust particles — UFOs — are interrupting the beams and making it harder to get the LHC running consistently.
This would create a layer of plasma from ionised gas, which would generate a thermonuclear shock wave that ripples through the fuel, promoting compression (Energy & Environmental Science, DOI: 10.1039 / b904609g).
Observations released in 2003 from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) suggested that the first stars started ionising gas after only 200 million years.
The original WMAP data suggested that the first stars started ionising gas after only 200 million years, seemingly leaving too little time for gas to gather into clumps and make stars.
The light's wavelength can also change noticeably when photons are scattered off ionised gas moving through space, providing a way to probe the velocity of such gas.

Outside the pyramid, they also used detectors that record muons indirectly when the high - energy particles ionise the gas inside.
In planetary nebulae, thought to be the evolved stage of pre-planetary nebula, the core is exposed and the hotter radiation it emits ionises the gas in the now weaker jets, which in turn glow.
