Why is the sky blue question?
Why is the sky blue question?
Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. The white light coming from the Sun is really made up of all the colors of the rainbow.
Why is the sky blue for kids?
The sky is blue because the air scatters blue light from the Sun across the sky and down to our eyes. Nitrogen molecules scatter blue light more than they do the other colors. So a little bit of blue light bounces around in the sky and then enters our eyes. That makes the sky look blue.

Why is the sky blue and sunsets red?
Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. This is why sunsets are often yellow, orange, and red.
Why evening sky is red?
Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining.
Why is space black?
At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day.
Are black holes?
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Why can’t you see the stars in space?
Our daytime sky is bright because of the diffusion of light through the atmosphere. Even in space, stars are relatively dim, and simply don’t produce enough light to show up in photos set for bright sunlight.
Can you see stars in space during the day?
Stars can be seen in the daytime sky, but this is a bit of a cheat. Stars, along with the brighter planets already mentioned, can be seen with the unaided human eye in a daytime sky (that is, when the sun is above the horizon) normally only during a total solar eclipse.
Are there any dead astronauts in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
Why is Venus so bright?
Venus is one of the brightest objects in the night sky. Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth.
Can I see Venus right now?
December 2020 will show you 3 bright planets as soon as darkness falls: Mars, Jupiter and Saturn. Venus, the brightest planet, is in the east before sunrise.4 days ago
What is the brightest light in the sky tonight?
It’s the star Sirius in the constellation Canis Major, brightest star in the sky. The bright planet Venus is also up before dawn now. But you’ll know Sirius, because Orion’s Belt always points to it.
Is Venus getting brighter?
Venus is now nearly three times brighter than it was at its faintest some months ago. And that’s saying something, because Venus always ranks as the second-brightest heavenly body in the night sky (after the moon). Venus’ reign in the evening sky started on Aug, and will come to an end on J.

Which is the biggest star?
The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
