Supernova. There are Chinese and European accounts from centuries ago of "guest stars," new stars that appeared and faded from view. We can see the expanding remnants of those supernova today--one is the Crab Nebula.
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
All sight its based on the light that objects either emit, reflect, or refract. The stars are little different in this regard. We judge distance using a number of different cues, a number of which indicate that the stars are far away.More distant objects will tend to appear smaller. The stars appear small.Any object that blocks a portion of the sky will block the stars from view, so we know the stars are more distant than those objects.When we move, objects we are looking at appear to change position relative to us. The farther away they are, the smaller the change. No matter how much we move there is no apparent change in the position of the stars, meaning they must be very far away.Indeed, the stars are much farther away than they appear to be as we are not able to perceive such distances directly.
Stars would appear much like our Sun when viewed at closer range and most would have planets and other objects orbiting them.
No. Stars are not fixed objects.
A galaxy is a massive collection of billions of stars, whereas a constellation is a group of stars (Sometimes other objects) that appear to form a pattern in the sky.
In the night sky, you can see stars, planets, the Moon, constellations, and sometimes satellites or shooting stars. These objects appear as points of light against the dark backdrop of space and can be observed with the naked eye or with the help of telescopes or binoculars.
They are not actually, moving, they just appear to be moving because we are. Consider that if you are on a train moving forward, objects that you pass by appear to move toward the read of the train.
The color of a star is related to its temperature. More massive stars are typically hotter and appear bluer, while less massive stars are cooler and appear redder. This relationship is described by Wien's law, which states that hotter objects emit more blue light and cooler objects emit more red light.
stars dont move, but as we move they appear to.
All stars eventually turn into Red Giants or Super Giants
Celestial objects appear to rise in the east and set in the west due to Earth's rotation. Their path across the sky is from east to west, following the motion of the stars. Additionally, celestial objects move at different rates depending on their distance from Earth and their orbital speeds.
Stars appear yellow because of their surface temperature. When a star is at a medium temperature, it emits a mix of colors that our eyes perceive as yellow. Stars cooler than the Sun appear more red, while hotter stars appear more blue.
