Sentences with phrase «light reaches a planet»

If comparatively more bluish or reddish light reaches a planet's surface than on Earth, photosynthetic plant - type life may may not be greenish in color, because such life will have evolved to different pigments in order to optimize their use of available and so color the appearance of the planet's land surfaces accordingly.

Oh, so in the vast known Universe, which reaches out for 15 BILLION light years in all directions, with over 100 BILLION galaxies, containing an average of 100 BILLION stars each, with most of those stars now thought to have multiple planets orbiting around them, you can't imagine that there would be at least ONE little planet SOMEWHERE with the right conditions for life without divine intervention?

3) knowing the speed of light is the universal constant, we can judge age of universe from how long it took those beams of light to reach our planet.

To reach the potentially habitable planet Proxima b, these «photogravitational» assists counterintuitively require first sending the light sail swooping blisteringly close to the bright, sunlike stars Alpha Centauri A and B — even though they are nearly two trillion kilometers farther from us than Proxima b's smaller, dimmer host star, Proxima Centauri.

We observed and spatially resolved the disk around the ~ 10 Myr old protoplanetary disk HD 100453 in polarized scattered light with SPHERE / VLT at optical and near - infrared wavelengths, reaching an angular resolution of ~ 0.02», and an inner working angle... ▽ More Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form.

First, such a planet is potentially close enough, at just over four light years, for us to reach and colonize it if we used nuclear rockets (NASA has proposed a plan for accomplishing this, dubbed Project Longshot).

New Horizons will shed light on this mystery once the spacecraft reaches closest approach to the dwarf planet.

Armed only with a backpack and an anti-gravity like light beam, he must transverse this crazy planet to reach his destination and hopefully catch a ride home.
