This fluctuation is analogous to genetic drift â a change in the population's allele frequency resulting from a random variation in the distribution of alleles from one generation to the next. It is even possible that in any one generation no marbles of a particular colour are chosen, meaning they have no offspring.
SOHO stands for Solar and Heliospheric Observatory and is a satellite that studies the Sun 24 hours a day, 365 days a year without interruptions. The spacecraft has 12 scientific instruments collecting information about the Sun ranging from activity in the Sun's corona to vibrations deep in the Sun's interior.or SOHO there are two main reasons: the unstable orbit at the L1 point and facility of communication in a halo orbit. If SOHO was sitting directly at the L1 point, it would always be right in front of the Sun.
Solar activity, such as solar wind, sometimes causes this and other problems. Scientists are trying to find ways to understand and forecast solar events. The SOHO mission is one way we are working to find the the answers. The Solar and Heliospheric Observatory is a byproduct of the European Space Agency and NASA. Together they have created and monitored the spacecraft since 1995. Although the primary mission was completed in 1997, scientists are still using the satellite, especially during the upcoming solar maximum. SOHO has 12 very important instruments.
