What objects can form tails millions of kilometers long when they pass near the sun?
Comets are objects that can form tails millions of kilometers long when they pass near the sun. The heat from the sun causes the comet's icy nucleus to vaporize, creating a glowing coma and two tails: one composed of dust and the other of ionized gas.
What does an astronomer need to observe either part of the sun's atmosphere?
An astronomer need not have any particular need to observe any part of the sun's atmosphere.
Is there gravity near the sun?
Yes, there is gravity near the sun. Gravity is a fundamental force that exists between all objects with mass, and the sun's mass creates a gravitational field that affects all objects in its vicinity, including planets and other celestial bodies.
What event helped prove Einsteins prediction that light bends near the sun?
The 1919 total solar eclipse provided the observational proof for Einstein's prediction that light bends near the sun due to its gravitational pull. This event allowed for scientists to observe stars near the sun during the eclipse and confirm that their positions shifted slightly, supporting Einstein's theory of general relativity.
What are asteroid sized objects that develop a huge bright tail when they come near the sun?
Asteroid-sized objects that develop a bright tail when they approach the sun are known as comets. Unlike asteroids, comets are composed largely of ice, dust, and rocky material. When they near the sun, the heat causes the ice to vaporize, creating a glowing coma and a tail that always points away from the sun due to solar wind. This distinctive tail can be quite striking, making comets visible even from Earth.
Who studies the sun moon and stars?
Astronomers study the sun, moon, and stars. They observe and analyze celestial objects in order to learn more about their properties, behavior, and evolution. Astronomy is a branch of science that focuses on the study of objects and phenomena in outer space.
How can you safetly observe the sun?
you can observe the sun with ou safety equipment but it is much better if you don't look at the sun with your naked eye.
What objects can form tails millions of kilometers long when they pass near the sun?
Comets are objects that can form tails millions of kilometers long when they pass near the sun. The heat from the sun causes the comet's icy nucleus to vaporize, creating a glowing coma and two tails: one composed of dust and the other of ionized gas.
What are the objects on the sun?
No objects on the sun. but there are sunspots and flares.
How can you safley observe the sun?
you cant
The sun and moon appear elliptical near the horizon due to?
The sun and moon appear elliptical near the horizon due to atmospheric refraction. This bending of light causes the celestial objects to look slightly flattened when they are closer to the horizon.
What will you observe in the sky if the moon appears above the horizon before the sun has gone below the horizon?
You will observe both the Sun and the Moon.
Why do the telecopes faceing the sun?
If a telescope is facing the sun it is being used to observe the sun (our local star). However, solar telescopes are SPECIAL and have a filter in them to block the sunlight down to a safe level. NOTE. If you stare at the sun or look at the sun through binoculars or a telescope the strength of the sunlight WILL BLIND YOU PERMANENTLY.
How do objects travel around the sun?
icy objects travel around the sun
Is it safe to look at the Sun?
No, it is not safe to look directly at the Sun. Doing so can cause permanent damage to your eyes, including blindness. Specialized solar viewing glasses or equipment should be used to safely observe the Sun.
What are the icy objects with huge trials that orbit the sun?
Tails, not trials. They're called comets, and their "tails" form when the comet gets near the sun, vaporizing away some of the ice.
Should you aim the mirror of a microscope at the sun?
Absolutely not. A microscope is designed to magnify and focus light to observe small objects, and aiming the mirror at the sun can cause intense heat and light to be focused onto the microscope's components, potentially causing damage or even starting a fire. It is crucial to always use a microscope in a controlled environment with appropriate lighting sources to ensure safe and accurate observations.
