Astronomers study celestial objects and phenomena, such as stars, planets, and galaxies, to understand the universe's structure and evolution. They often use telescopes and other instruments to collect data, analyze it, and develop theories about cosmic processes. Additionally, astronomers may engage in public outreach and education to share their findings with the broader community.
Scientists who study stars are known as astrophysicists or astronomers. Astrophysicists focus on understanding the physical properties, processes, and evolution of stars, while astronomers may also study their positions, movements, and interactions in the universe. They utilize telescopes and other instruments to observe stellar phenomena and often work in research institutions or universities.
A telescope is used to see stars and planets by collecting and magnifying light from distant objects in the night sky. Telescopes come in different types such as refracting, reflecting, and compound telescopes, each with its own advantages for observing celestial bodies. Professional astronomers and amateur stargazers alike use telescopes to explore the universe and observe objects like galaxies, nebulae, and planets in detail.
Ratio telescopes, often referred to as radio telescopes, are used to study the structure of the Milky Way galaxy because they can detect radio waves emitted by celestial objects, allowing for observations through interstellar dust that obscures optical wavelengths. This capability enables astronomers to map the distribution of hydrogen gas and other components of the galaxy, revealing its spiral structure and dynamics. Additionally, radio telescopes can capture data from various wavelengths, providing a more comprehensive understanding of the galaxy's morphology and behavior.

Astronomers find it challenging to locate planets with telescopes primarily due to the vast distances involved and the relative faintness of planets compared to their host stars. Planets do not emit their own light; instead, they reflect light from their stars, making them much less visible. Additionally, the glare from stars can easily obscure nearby planets, complicating detection. Advanced techniques, such as transit photometry and radial velocity measurements, are often required to identify these distant worlds.
Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.
Nowadays, the bulk of the work astronomers do is on computers. They spend a small portion of their time at telescopes actually taking data. Astronomically-useful telescopes rarely have eyepieces you can look through. Radio, ultraviolet, or infrared telescopes collect light that you can't even see with your eye! Telescopes that collect visible light often have electronic cameras called CCD cameras that create an image in a computer. Many telescopes are used to create a spectrum (the light is split into a rainbow, and the brightness of each color is measured). Radio telescopes record signals that astronomers can reconstruct using a computer to make an image or a spectrum.
Large telescopes are often housed in observatories located in remote and high-altitude areas to minimize light pollution and atmospheric interference. These locations provide clearer skies and better visibility for astronomical observations.

The primary problem overcome by radio interferometry is the limited resolution of individual telescopes. By combining signals from multiple telescopes, interferometry creates a virtual telescope with a larger diameter, which improves the resolution and allows astronomers to see finer details in the radio sources being observed.
Radio telescopes are often placed in valleys because the surrounding hills and mountains shield them from radio interference generated by human activities. Valleys provide a natural barrier that helps to block out unwanted signals and enhance the sensitivity of the telescopes to detect faint radio signals from space. Additionally, valleys can also help to reduce the impact of wind and atmospheric disturbances on the telescopes, leading to clearer observations.

To take pictures of other galaxies, astronomers use telescopes equipped with sensitive cameras to capture light emitted by the distant galaxies. These telescopes are often placed in space or in remote locations to minimize interference from Earth's atmosphere and light pollution. The images captured are then processed and analyzed to study the properties and characteristics of the galaxies.
The collective noun is team; a team of astronomers.
