Previously, Earth was the only known body in the solar system with a dynamic crust, which is considered helpful in the evolution of life on the planet. Phytoplankton have evolved the ability to use the blue and green light found in the ocean. The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Hydrothermal vent teeming with life. Light behaves very differently when it moves from air into water. They have color vision, since light near the surface still has color.

At the poles of the moon, the temperature never rises above minus F minus C.
ocran Into the darker depths As our diver continues to descend only a few more meters, she begins to go from day to night. The next zone is the dysphotic or twilight zone. In deeper, mesopelagic regions with less light, the animals often have bizarre adaptations to increase their visual sensitivity. Seawater absorbs light much more strongly than air does, but visible light is made up of livee rainbow of different wavelengths, each perceived by us as a different color.
The ocean is very, very deep; light can only penetrate so far below the surface of the ocean.
luve Today, however, new technology promises to reveal s.tberlin light operates in the ocean and how it creates a unique environment and assorted phenomena that ocean life is adapted to. Animals that live in the abyssal zone feed on detritus raining down from above—or on each other. Octopus, squid, and the hatchet fish are some of the animals that can be found in this zone. The region below this is known as the aphotic no-light zone, but this is only true for sunlight, as bioluminescence is common.
Many are simply transparent, matching their background in all situations. Light in the ocean is like light in no other place on Earth.
Many animals contain compounds in their tissues that protect them against UV radiation by scattering, reflecting, or absorbing UV light. Have a news tip, correction or comment?
Europa is the smallest of the four but it is one of the more intriguing satellites.

Providing the oxygen we breathe Beyond their impact on light, marine phytoplankton also have enormous impact on lve planet. At the same time seawater absorbs red, orange, and yellow wavelengths, removing these colors.
This possibility of extraterrestrial life is one of the reasons interest in Europa remains high. In addition, if coastal waters become less clear due to human activities, photosynthesis by phytoplankton may decrease. Three people, usually two scientists and a pilot, can barely fit. When light hits a substance, it can do one of three things: At the time, the Catholic Church supported the idea that everything orbited the Earth, an idea supported in ancient times by Aristotle and Ptolemy.
They hide in the depths during the day, rising to feed at night, or they stay near the surface, hiding in the glittering background of the lensing waves.

Hydrothermal vent teeming with life. Long, tubular eyes capture and detect low light levels. This ocean could contain some form of life. The photophores give off a greenish light. The left image shows Europa in approximately true color and the right image shows Europa in enhanced color to bring out details. The presence liev water beneath the moon’s frozen crust dsylight scientists rank it as one of the best spots in the solar system with the potential for life to evolve.

They remove huge amounts of the greenhouse gas carbon dioxide from the atmosphere, turning it into organic matter via photosynthesis.
The researchers cautioned that the plumes haven’t yet been fully confirmed, but they do provide a suggestion that there is water in Europa’s ocean jetting to the surface. While researchers spotted evidence inandthe true nature of the plumes — and why they appear sporadically — requires more observations. But it wasn’t until the 19th century that the moons were officially given the so-called Galilean names we know them by today.
A different research team, after repeated attempts to confirm the observations, saw apparent plumes in and Over time, moons around other planets were discovered — and st.berlim moons found around Jupiter.
Marius, the other “discoverer,” first proposed that the four moons be given their current names, from Greek mythology. Scientists estimate that Europa’s surface is about 20 million to million years old, which st.berlon it fairly young.
