eclipse
Q. When the moon is just a shadow and looks like no moon at all?
A lunar eclipse happens when the Earth’s shadow covers all or part of the moon. This can only happen during a full moon, so first, it helps to understand what makes a full moon. Like the Earth, half of the moon is illuminated by the sun at any one time.

Q. When the moon looks like a big white circle?
What you were seeing is an optical illusion, caused by reflections of ice crystals in the upper atmosphere from cirrus or cirrostratus clouds. This is called the “halo effect,” or a Lunar Halo, and it is caused by light rays diffracting around the moon. Twenty thousand feet above your head are thin wispy cirrus clouds.
Q. On which day we Cannot see the moon?
new moon day
Q. Why does the moon look so low in the sky tonight?
It’s a true physical effect, caused by the fact that – when the moon is low in the sky – you’re seeing it through a greater thickness of Earth’s atmosphere than when it’s overhead. The atmosphere filters out the bluer wavelengths of white moonlight (which is really reflected sunlight).
Q. Why is the moon so big and low?
This happens because the Moon’s light travels a longer distance through the atmosphere. As it travels a longer path, more of the shorter, bluer wavelengths of light are scattered away, leaving more of the longer, redder wavelengths.
Q. What is the bright star next to the moon tonight?
Regulus
Q. What is the orange star in the sky tonight?
Orange Arcturus
Q. What is the bright white star in the sky?
Why is Sirius so bright? Sirius is bright enough to dominate the night sky after sunset particularly if there are no planets around. It’s very bright because: Sirius is a big blue-white star 25 times the mass of our Sun.
Q. How hot is the hottest star in the universe?
210,000 K.
Q. What are the hottest types of stars?
The spectral sequence is also a colour sequence: the O- and B-type stars are intrinsically the bluest and hottest; the M-, R-, N-, and S-type stars are the reddest and coolest.
Q. How does Venus look like?
From space, Venus is bright white because it is covered with clouds that reflect and scatter sunlight. At the surface, the rocks are different shades of grey, like rocks on Earth, but the thick atmosphere filters the sunlight so that everything would look orange if you were standing on Venus.
