Astronomy through time worksheet

How do we know how many light years away something is?
There is no direct method currently available to measure the distance to stars farther than 400 light years from Earth, so astronomers instead use brightness measurements.
It turns out that a star's color spectrum is a good indication of its actual brightness..
How is time used in astronomy?
The basic unit of astronomical time is the day—either the solar day (reckoned by the Sun) or the sidereal day (reckoned by the stars).
Apparent solar time is based on the position of the Sun in the sky, and mean solar time is based on the average value of a solar day during the year..
Which subject is best for astronomy?
Required Skillset for Astronomy
The ability to solve complex problems, conduct research, analyse data, math, physics and knowledge in basic science-related subjects are the most important skill sets of an individual pursuing astronomy or aspirants of an astronomer..
Astronomer work environment
They spend a lot of their time working from a computer, where they conduct their research using the latest technologies.
Some astronomers also travel frequently.
They visit other laboratories across the world to learn about different experiments, share information or borrow equipment.
One of the oldest ways of finding the time is with a sundial.
The further west you are, the later the Sun rises and the later it sets.
When a sundial in Greenwich is showing 9.00 a.m., one to its west in Cardiff will show 8.47 a.m.
The time indicated by a sundial is called the 'local apparent time'.
Sedna is three times farther away from Earth than Pluto, making it the most distant observable object known in the solar system.
It is 143.73 billion km from the Sun, thus giving the Solar System a diameter of 287.46 billion km.

How does Hubble measure the age of the universe?

Hubble also uses galaxies as “markers of space” to measure the expansion rate
And hence the age
Of the universe. Studies of galaxy motion (building on earlier studies of stellar motion) provide evidence that an invisible form of matter
Later d믭 dark matter
Dominates the universe.
