Eventually, as the sun exhausts its fuel, it will lose energy and begin to expand. It may become so large it will engulf the earth, destroying it. Whether or not the Earth is engulfed, at most a lifeless charred mass will be left behind. This will happen no matter what in three to five billion years.

Astronomers use telescopes on Earth to collect and analyze light from celestial objects, which allows them to study their properties, such as composition, distance, and motion. By employing various types of telescopes—optical, radio, and infrared—they can observe different wavelengths of light, revealing information that might not be visible to the naked eye. Advanced imaging and spectroscopy techniques enable astronomers to resolve complex problems, such as mapping star formation in galaxies or detecting exoplanets. Additionally, ground-based telescopes are often equipped with adaptive optics to compensate for atmospheric distortions, enhancing the clarity and detail of observations.
From Encyclopedia we can get a list of famous & not famous astronomers & astronauts of the past & present.
THE EARTH WOULD END. All things would stop eventually, leaving a hot core and a very, VERY dead Earth. Earth would PROBABLY stop moving, disrupting the Solar System. SO: Convection currents, if you stop, the universe will END.
Before space photos confirmed Earth's roundness, evidence included observations such as the way ships disappear hull-first over the horizon, the curved shadow Earth casts on the Moon during a lunar eclipse, and variations in star visibility when traveling north or south. Additionally, early astronomers like Aristotle noted the circular shape of the Earth's shadow during eclipses and observed that different constellations are visible in different latitudes, supporting the idea of a spherical Earth.
India astronomers recognized that the earth was a sphere.
That would be planet Earth. Our very own home planet.
They are called astronomers.
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
Arab astronomers determined that the Earth was round in shape through a combination of observations and mathematical calculations. They also accurately calculated the Earth's circumference to an impressive degree of accuracy for their time.
No.
Earth
Astronomers study celestial objects such as stars, planets, and galaxies, which are located in space above Earth. While astronomers may not focus on the geology or atmosphere of Earth, their work is still aligned with studying the natural phenomena of the universe, making them closely related to Earth scientists.

Astrologers look at stars and predict events according to what they see. They are different from astronomers because astronomers have a scientific basis, while astronomers do not.
