What else can I help you with?
How does an astronomer estimate the temperature of a star by observing it?
By the color.
How can you tell whether you are looking at a planet or a star in the night sky over the course of a nights observation?
We know it by observing that the stars blink in the sky while planets do not blink.
What will you see if you observe a star?
When observing a star, you will see a bright point of light in the night sky.
Can A planet's mass can be determined by observing it transit a star?
Yes, a planet's mass can be determined by observing its transit across a star. By measuring the dip in the star's brightness during the transit, astronomers can calculate the size of the planet and its gravitational effect on the star, which provides information on the planet's mass.
What information can you get in observing the star?
In observing a star, you can determine its brightness, color, position in the sky, and any variations in brightness over time. You can also analyze the star's spectrum to learn about its chemical composition, temperature, age, and evolutionary stage. By studying the motion of the star, you can infer its distance from Earth and its relative motion in space.
Can our eyes tell us our sexuality?
Eyes can tell our sexuality or sexual orientation by observing pupil dilation.
How do astronomers tell if a star is binary or has planets?
a way to tell if a star has planets is to observe a wobble in its position. i.e when a planet orbits a star it pulls at it making the star move slightly in its direction. when seen from far away it looks like the star is moving back and forth. This is a very rough explanation and can no doubt be improved upon.
Describe four methods for discovering extrasolar planets?
Discovering the essential Universe by Neil F. Comins fourth edition Extrasolar planets can be discovered by observing them indirectly by using microlensing, by observing the Doppler shift of the star due to the pull of the orbiting planet, by observing the periodic variation of the proper motion of a star, and by observing the periodic variation of the starlight due to the planet passing between that star and Earth, an event called a transit.
What are 3 things that we can learn about a star by observing it's spectrum?
By observing far away stars in our galaxy through a spectroscope, we are able to see the spectrum that appears from the substances in these stars. Each element has a unique spectrum when light is shone through it, so we are able to determine what elements make up certain stars.
How can you tell a specimen is a eukaryote?
By observing its organells. If a nucleus or membranous organelle present
You are observing a star about 100 light years away how old is the most recent information you can get aboutthis star?
The most recent information we can receive about the star would be from about 100 years ago, as it takes light around 100 years to travel a distance of 100 light years from the star to reach us on Earth.
What is the location of a star when it twinkles a lot?
Outerspace ... the twinkling effect happens when observing the star(s) through earth's atmosphere. If you were in space, they would not twinkle.
