ScienceCasts: An Early Start for Noctilucent Clouds


Noctilucent clouds, clouds that can only be seen when the Sun is below the horizon, are behaving differently this year according to NASA. The clouds, which are the highest in altitude of all the clouds are normally very faint, often too faint to be seen with the naked eye, but they become visible when illuminated by sunlight shining up from below the horizon. Their appearance earlier in the year than usual may hint that there are changes occurring in the Earth's atmosphere. You can read a very full explanation of the phenomenon here.
There are two coronal holes on the Earth side of the Sun and the winds blowing from them will hit on June 9-10th and will give rise to auroras at high latitudes.

A robotic spaceship called Albert Einstein was launched on June 5th taking cargo to the international space station. It was launched by the European Space Agency and will dock with the space station on June 15th.
