Astronomers work year-round, but they may have different focuses during specific times. Observational work is often done when the night sky is clearest, which can vary depending on the location. The summer and fall months are generally good for observing, with fewer weather disruptions.
Yes, measuring parallax from the same spot every year helps astronomers accurately calculate the distance to stars by observing their apparent shift in position. By observing the parallax over time, astronomers can account for the Earth's orbit and improve distance calculations.
Astronomers use the principles of physics, chemistry, and mathematics to learn about the fundamental nature of the universe, including the sun, moon, planets, stars, and galaxies. As such, astronomy is sometimes considered a subfield of physics. They also apply their knowledge to solve problems in navigation, space flight, and satellite communications and to develop the instrumentation and techniques used to observe and collect astronomical data.Almost all astronomers do research. Most of them also have teaching as part of their work, usually in a university.Some are theoreticians, working on the laws governing the structure and evolution of astronomical objects. Others analyze large quantities of data gathered by observatories and satellites and write scientific papers or reports on their findings. Some astronomers actually operate large space-based or ground-based telescopes, usually as part of a team. However, astronomers may spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments.A small number of astronomers work in museums housing planetariums. These astronomers develop and revise programs presented to the public and may direct planetarium operations.Work environment. Most astronomers do not encounter unusual hazards in their work. Astronomers who make observations with ground-based telescopes may spend many hours working in observatories. This work usually involves travel to remote locations and may require working at night. Astronomers whose work depends on grant money may spend a lot of time writing grant proposals to keep their work funded.Astronomers may need to work at odd hours to observe celestial phenomena, particularly those working with ground-based telescopes.
Astronomers often call this the planet's year. For Earth that's about 365 and 1/4 days.
The salary of a professional astronomer in South Africa can vary depending on experience, qualifications, and employer. On average, a professional astronomer in South Africa can earn between ZAR 300,000 to ZAR 800,000 per year.
A light year is the distance that light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers). The riddle often plays on the concept of distance rather than time, as it can be misleading to think of it as a measure of time when it actually quantifies space. Astronomers use light years to express vast distances in the universe, such as the distance to stars and galaxies. The riddle emphasizes the fascinating relationship between the speed of light and the immense scales of the cosmos.
In a day? In a year? Over their careers? Very vague question!

They don't. Light years are a distance measurement, not a time measurement.

Most astronomers are college faculty or staff. Their salary varies considerably depending on how prestigious the college is, how prestigious they themselves are, how experienced they are, whether they have study grants or not, and a variety of other factors.
Astronomers measure light years in space by calculating the distance that light travels in one year. They use the speed of light, which is about 186,282 miles per second, to determine how far light can travel in a year. This distance is equivalent to one light year. By observing the time it takes for light to reach Earth from distant objects in space, astronomers can estimate their distance in light years.
they Egyptians made a calendar by looking at the stars and each year they found out it flooded at the same time period all the time
the most wonderful time of the year is Christmas!

Astronomers have not yet made any findings regarding the possibility of life on Mars.
