How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. By observing how a star's position changes when viewed from different points in Earth's orbit around the Sun, astronomers can calculate the star's distance based on the angle of this apparent shift.
How do astronomers measure the distance to stars that are less than 1000 light-years from the earth?
Because the angle of shift is very small and extremely difficult to measure, scientists usually use photography to measure the shift. The star is photographed at the beginning and end of a six-month period, and its position in relation to other stars is studied each time.
How do astronomers determine whether stars have moved?
The easiest way is to look at a picture of the star and then look at another one taken six months later. If it has moved, that can be seen on the photo when you look at it in relation to the stars in the background of the photo. That was the first method used to find the distance to the nearest stars, and it was a big surprise to find out how far they actually were.
Why can't astronauts stay in space longer than six months?
Astronauts can't stay in space longer than six months primarily due to the harmful effects of prolonged exposure to microgravity and cosmic radiation. Extended time in microgravity can lead to muscle atrophy, bone density loss, and fluid shifts that affect vision and overall health. Additionally, the risks associated with radiation exposure increase over time, potentially leading to higher chances of cancer and other health issues. Support systems for life, such as food, water, and psychological well-being, also become increasingly challenging to maintain beyond this duration.
How many kids did Zeus have with rhea?
none. she was zeuse's mother. so that woould be kind of weird.
What kind and how much education is required to be a astronomer?
Typically, professional astronomers have a PhD in astrophysics, or something similar. This requires a lot of mathematics, physics and some chemistry, and would take about six to seven years of university study, full-time. Amateur astronomers can and do make contributions to the field, but it doesn't pay.

What are the early signs of radiation sickness?
The first indicators of radiation sickness are nausea and vomiting. Symptoms will begin within the first six hours after over exposure.
What are the six sub-intelligence disciplines of masint?

Why you study about six stroke engine?
This is a new and emerginf technology and needs to have a lot of research work for this.. so we have to study about this new technology too. Like the innovative design of NIYKADO Six Stroke Engine.
