Today's astronomers inherit the benefit of literally centuries of measurements
with ever greater accuracy and precision. Standing as they do on the shoulders
of giants, they have begun to perceive a true sense of the huge ginormity of the
sun and its dimensions, and are coming to recognize that the sun is so gigantic
that it has never been lost.
What else can I help you with?
How long do astronomers estimate the sun will last before it begins to die?
Astronomers think the sun will die in 2012
What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
What did most ealy astronomers think made up the universe?
Early astronomers believed that the universe was made up of the Earth at the center, surrounded by concentric spheres holding the Moon, Sun, planets, and stars. This model of the universe, known as the geocentric model, was proposed by Ptolemy in the 2nd century.
Did astronomers believe that the sun was part of earth?
No.
How long have astronomers been trying to find out what the sun orbits?
For two or three hundred years, astronomers have had a fair idea the the Sun is not the center of the Universe.
Why can astronomers predict eclipses?
Astronomers can predict eclipses because they understand the movements of the Earth, Moon, and Sun in space. By tracking their positions and orbits, astronomers can calculate when the Moon will pass in front of the Sun (solar eclipse) or when the Earth will pass between the Sun and the Moon (lunar eclipse). This knowledge allows astronomers to forecast eclipses with accuracy.
Why do astronomers use special filters to look at the sun?
Astronomers use special filters to observe the sun because the sun emits high-intensity light that can damage the eyes and sensitive equipment. These filters help to reduce the brightness of the sun and allow astronomers to safely study its features, such as sunspots and solar flares.
What scientist studies the function of the sun?
Astronomers study celestial bodies, helio astronomers specifically study suns.
How do astronomers know that hydrogen is present in almost every star in the universe?
Astronomers use spectroscopy to analyze the light emitted by stars. By studying the absorption lines in a star's spectrum, astronomers can identify the elements present in its composition. Since hydrogen leaves a distinct signature in these absorption lines, scientists have found that hydrogen is the most abundant element in stars, including our Sun.
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
Who did aristarchus influence?
Aristarchus of Samos influenced later astronomers by proposing a heliocentric model of the universe, where the Sun, not the Earth, was at the center. His ideas laid the foundation for the work of astronomers like Copernicus and Galileo.
What is it about the Sun's corona that astronomers don't understand?
the corona is much hotter than the layers of the sun that are closer to the sun's interior
