lesson 6

i think that they have successfully taken knowledge from the first time we shared, for example giving more time for notes etc. I think that the kahoot was very knowledgeable. despite that, there was too much information on each slide, and it was not very visible, whereas our's had less information to comprehend and I give probs to them for sharing.

notes:

The night sky refers to the nighttime appearance of celestial objects like stars and planets visible in clear sky bet. Sun rise&set. It is also not completely dark. The scientific study of celestial objects visible at night takes place in the night sky Is called observational astro. Light pollution is the presence of unwanted, inappropriate or excessive artificial lighting. Clouds obscure the view of other objects in the sky, through varying thicknesses of cloud cover have different effects. A constellation is the area on the celestial sphere in which a group of visible stars forms a perceived outline or pattern, typically representing an animal, mythological subject or inanimate object. Astronomers use constellations as a map for the night sky.The Big Dipper is helpful for navigation in the northern hemisphere because it points to the Polaris, the North Star. Planets, named from the greek word for ‘wandered’, process through the star field a little each day, executing loops with time scales dependent on the length of the planet’s year of orbital period around the solar system. With telescopes or good binoculars, the planets appear as discs demonstrating finite size, and it is possible to observe orbiting moons which cast shadows onto the host planet’s surface. Comets come into the night sky only rarely. Meteors streak across the sky very infrequently. Earth’s Moon appears as a grey disc in the sky with cratering visible to the naked eye. Some of the most spectacular moons come during the full moon phase near sunset or sunrise.shortly after sunset and before sunrise, artificial satellites often look like stars, similar in brightness and size, but relatively larger. Zodiacal light is a glow that appears near the points where the sun rises and sets, and is caused by sunlight interacting with interplanetary dust.
