They have reflective surfaces so lights from the stars and earth are reflected making it seem to give out light. In greater depth: Some satellites, such as the International Space Station and the Space Shuttle, are big objects with large reflective surfaces. Other satellites are smaller, and not as easily visible. When the satellite is in sunshine, it reflects light like anything else.
It's easy to see satellites in the hour after sunset and hour before sunrise. Look for small bright objects moving rapidly in roughly west-to-east directions. It is common for satellites to quickly fade from view as they move from sunlight into the Earth's shadow in the evening, or suddenly appear in the morning going from dark to light.
There are several web sites that you can visit to see what satellites ought to be visible from your location; a few are linked in the "Related Links" section below this text.
One neat thing to watch for is an "Iridium Flare". The early-model Iridium satellite telephone system deployed a number of very large high-orbit satellites. Iridium satellites have very large solar power arrays, which act like giant mirrors in space. When the Sun's light is reflected from these panels, it is frequently visible as a very bright flash. These flares are only visible for a few seconds, and do not leave a trail like a meteor would.
The North Star is visible from any part of the northern hemisphere. So on a clear night, it can be seen from Dublin.
On any night of the year, Polaris can be seen from the northern hemisphere and cannot be seen from the southern one. (Assuming the sky is clear in the north.)
they traveled at night so that they couldn't be seen as easily.
No. There has never been any proof of this and there have been billions of people who have seen dead people at night.
There was a stoker who had been to sea for 26 years who said that he'd never seen it as flat, calm, and smooth as that night.
Artificial satellites can be seen with the naked eye when they reflect sunlight. The best time to see them is typically during dusk or dawn when the sun is below the horizon but the satellite is still illuminated. Satellites appear as moving points of light against the night sky.
Planets, moons, asteroids, artificial satellites.
It means that you are outside, the moon is in a clear patch of sky and probably full, and in the opposite direction from the moon, there is probably the leftovers of a rainshower.
Yes. It could be seen from anywhere on Earth, if the night sky was clear there.
Objects observed in the sky during the day include the Sun, clouds, and sometimes the Moon, along with birds and aircraft. At night, notable objects include the Moon, stars, planets, and constellations. Additionally, artificial satellites and meteor showers can also be seen under the right conditions. Weather phenomena like auroras may also be visible at night in certain regions.
light emitted by the satellites
Yes, easily, on any clear night.
Stars and planets appear in the night sky. The Moon also appears every night in different phases. Additionally, satellites and other human-made objects can sometimes be seen passing overhead.
Objects that reflect light and can be seen from Earth include the Moon and planets in our solar system, such as Venus and Mars. These celestial bodies do not produce their own light but instead reflect sunlight, making them visible in the night sky. Additionally, artificial satellites and space debris can also reflect light, sometimes appearing as bright points moving across the sky.
Stars are typically seen at night when the sky is clear and dark, away from light pollution. You can also see some stars during the day if the conditions are right, but they are most visible at night.
A dim rainbow can be seen at night anywhere, when the moon is behind you in a clear patch of sky and the air in front of you is loaded with heavy fog or droplets of water after a rain.
White is a color that can be easily seen both day and night. During the day, white stands out against most backgrounds, while at night, white objects can be more visible under artificial lighting or moonlight.
