Sentences with phrase «more radiation from its star»

Not exact matches

Infrared radiation passes through interstellar dust much more easily than visible light, so by looking at the infrared light from a galaxy we can learn about the new stars forming within the clouds of dust and gas.

Incrementally adjusting its angle as it approaches to soak up more radiation pressure from the stars, that sail could bleed off enough speed to be captured into orbit within the system.

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.

As more stars and galaxies formed, they eventually generated enough radiation to flip hydrogen from neutral, a state in which hydrogen's electrons are bound to their nucleus, to ionized, in which the electrons are set free to recombine at random.

Because Proxima b is so much closer to its star than Earth is to the sun, the flare would have blasted Proxima b with 4,000 times more radiation than Earth typically gets from the sun's flares.

In 1983, an orbiting satellite called IRAS discovered far more infrared radiation — which has waves longer than red light — coming from the Vega than expected for small interstellar dust grains found around young, early - type stars (Harvey et al, 1984).

Webb's giant sunshield will protect it from stray heat and light, while its large mirror enables it to effectively capture infrared light, bringing us the clearest picture ever of space objects that emit this invisible radiation beyond the red end of the visible spectrum — early galaxies, infant stars, clouds of gas and dust, and much more.

So while it's true that organisms living deep in the Earth are not exposed to the high - energy radiation found when you travel between planets or more hypothetically between stars, the systems that cells have evolved to repair damage done by reactive oxygen species will be useful whether they arise from rocks or from cosmic rays.

For about two weeks the star could be seen in daylight, but at the end of November it began to fade and change color, from bright white over yellow and orange to faint reddish light, finally fading away from visibility in March, 1574, having been visible to the naked eye for almost 16 months (more about Brahe's «acid tongue and silver nose,» the cultural shock of the «new star,» and how supernovae create high - energy radiation from Wallace H. Tucker).

it's much more reasonable to conclude that our solar system is receiving more radiation, either from the sun or nearby stars, for whatever as yet unknown reason.
