Early astronomers used devices like the astrolabe and the sextant to find the altitude of a star. The astrolabe, which dates back to ancient Greece, allowed astronomers to measure the angle of celestial bodies above the horizon. The sextant, developed later, is more precise for measuring angular distances and was particularly useful for navigation at sea. Both instruments played a crucial role in understanding the positions of stars and planets.

Why is it difficult for astronomers to see new stars in the process of birth?
Astronomers find it challenging to observe new stars in the process of formation because these nascent stars are often hidden within dense clouds of gas and dust. These materials can obscure visible light, making it hard to see the stars directly. Instead, astronomers rely on other wavelengths, such as infrared and radio, which can penetrate these clouds and reveal the stars' early development stages. Additionally, the timescales for star formation can vary significantly, complicating the observation of specific birth events.
Why do astronomers find it difficult to locate extrasolar planets with telescopes-?
Light from the stars they orbit makes it difficult to see them.

How long had astronomers been searching for Pluto?
Astronomers had been searching for Pluto since the early 20th century, particularly after the discovery of Neptune in 1846, which led to speculation about an additional planet due to irregularities in Uranus's orbit. The search intensified in the 1920s, culminating in the discovery of Pluto by Clyde Tombaugh on February 18, 1930, after extensive observations and calculations. Thus, the search spanned several decades, driven by the quest to find the elusive ninth planet of our solar system.
What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
Why astronomers do what they do?
astronomers do what they do because they want to find bigger and better things that have yet to be discovered.
How do astronomers find out about changes in galaxies over time?
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
How do you find the altitude of a triangle?

What was the obsession of early alchemists?
One was to find the "philosopher's stone" a device that could turn lead (a base metal) into gold.
Why do astronomers find it necessary to identify the stars?

How do you find slope altitude?
If the slope of a line is m then the slope of an altitude to that line is -1/m.
How could the altitude and azimuth be important?
There are a number of ways to describe locations or positions. One of these is to describe the direction toward an object in degrees; this is the "azimuth". For objects in the sky, we must also know the angular elevation above the horizon, or "altitude angle". This is usually shortened to "altitude". By specifying the azimuth angle and altitude angle, we can describe precisely the direction of any object in the sky.
Find The altitude of an equilateral triangle if one of its sides measures 12cm?
Altitude = 10.4 (10.3923) cm
Do astronomers find life in the universe?
Other than us, not yet.
Why astronomers go to the outerspace?
To learn about space & find out more about Mars.
Will Astronomers find evidence of life on Sedna?
It's very unlikely.
