Sentences with phrase «ultraviolet radiation from stars»

New Hubble telescope images show ultraviolet radiation from stars born during the universe's adolescent phase.

The Australian telescope was one of several payloads carried into space by the shuttle Endeavour to observe ultraviolet radiation from stars and galaxies.

Here, the bright orange lanes have been whittled away by ultraviolet radiation from the star, turning them into knots with cometlike tails.

This discovery refutes existing theories, indicating that ultraviolet radiation from the star would destroy molecular gas and dust, and bringing the first direct detection of ionized gas wind along with a supersonic jet and an accretion disk.

Not exact matches

These globules are under fierce bombardment from the ultraviolet radiation from nearby hot young stars.

Larger Bok globules in quieter locations often collapse to form new stars but the ones in this picture are under fierce bombardment from the ultraviolet radiation from nearby hot young stars.

Scientists think that when the first stars were born, these luminous objects and the galaxies they formed eventually pumped out X-rays and ultraviolet radiation that ripped electrons from their proton partners.

Ultraviolet light from early, blueish stars (illustrated) interacted with hydrogen gas, causing it to absorb background radiation, and creating a signature scientists have now detected.

Although Proxima Centauri's dimness provides the planet with a balmy climate, the star is prone to outbursts of harsh X-ray and ultraviolet radiation, which could damage any chance of life on the planet — X-rays hit the surface 400 times more often than those from the sun pummel Earth.

A computer model developed by the team suggests that the grains must reach the size of boulders within a million years; otherwise, the dust particles and circumstellar gases will be blown apart by fierce ultraviolet radiation from the nebula's hottest, most massive young stars.

Using data gleaned from the Hubble telescope, researchers have calculated the amount of ultraviolet (UV) radiation the planets receive from their star, a Hubble press release reports.

This radiation comes from established stars, rather than newborn stars that blaze furiously in ultraviolet light.

Astronomers have known for about a decade ultraviolet and X-ray radiation from the main star in HD 189733 are evaporating the atmosphere of HD 189733b over time.

Gas and dust clouds in 30 Doradus, also known as the Tarantula Nebula, have been sculpted into elongated shapes by powerful winds and ultraviolet radiation from these hot cluster stars.

When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.

The formation of a stratosphere layer in a planet's atmosphere is attributed to «sunscreen» - like molecules, which absorb ultraviolet (UV) and visible radiation coming from the star and then release that energy as heat.

Eventually, as the early stars grew in numbers and brightness, they would have emitted enough ultraviolet radiation to «reionize» the hydrogen, removing the electrons from their bonded protons and neutrons.

The first stars, however, also began emitting intense ultraviolet radiation that «re-ionized» neutral hydrogen atoms formed after the Big Bang by tearing electrons from their proton nuclei.
