A 1.43MSun main sequence star is found to have a planet in its habitable zone. What is the expected lifetime (in years) of the star? (Assume that the expected lifetime of the Sun is 11 ✕ 109 years. Round your answer to at least three significant figures.)
Using the figure above, if Earth orbited this star, how far along the timeline would it get?
Your astronaut twin brother is exploring a planet of a star far out in space. Ignoring the time spent exploring the planet (during that time your watches run equally fast) also ignoring the time spent getting up to cruising speed, and slowing down for landing, (after all those times are very short compared to the time cruising,) how fast will that space ship have to cruise in order for your brother to age 2 years for every year you age?
Using the GUFSA Template. Round off your final answer to the nearest hundredths. As we already know, rockets travel at very high speeds. How much time will it take a rocket (in seconds) to reach the moon if the moon is 238,900 miles away from the Earth, and the rocket is travelling 1,800,000 centimeters per minute? (express your answer in meters per second)

- Based upon the evolution of stars, place the following elements in order of least to most common in the Galaxy: gold, carbon, neon. What aspects of stellar evolution formed the basis for how you ordered the elements?arrow_forwardWhat does it mean to say that the universe is expanding? What is expanding? For example, is your astronomy classroom expanding? Is the solar system? Why or why not?arrow_forwardSuppose astronomers discover a radio message from a civilization whose planet orbits a star 35 lightyears away. Their message encourages us to send a radio answer, which we decide to do. Suppose our governing bodies take 2 years to decide whether and how to answer. When our answer arrives there, their governing bodies also take two of our years to frame an answer to us. How long after we get their first message can we hope to get their reply to ours? (A question for further thinking: Once communication gets going, should we continue to wait for a reply before we send the next message?)arrow_forward
- Human civilization is about 10,000 years old as measured by the development of agriculture. If your telescope collects starlight tonight that has been traveling for 10,000 years, is that star inside or outside our Milky Way Galaxy? Is it likely that the star has changed much during that time?arrow_forwardDo the previous problem again, this time using the information that the Sun is 150,000,000 km away. You will get a very large number of km as your answer. To get a better feeling for how the distances compare, try calculating the time it takes light at a speed of 299,338 km/s to travel from the Sun to Earth and from Alpha Centauri to Earth. For Alpha Centauri, figure out how long the trip will take in years as well as in seconds.arrow_forwardImagine that in the future, scientists plan on colonizing planets that orbit other stars. Based on your knowledge of the life cycle of stars, decide which type of star (High mass or Low mass) the planet should orbit that would allow for human life to safely live on that planet for the longest period of time. Explain your answer using examples from the life cycle of each star.arrow_forward
- Why are so many astronomical objects in the universe flat today? (Like the solar system, Saturn's ring, black hole accretion discs) Let's focus on our galaxy. Originally, the galaxy was a huge spherical cloud of gas and dust, much larger than it is today, and rotating much more slowly. Explain using gravity and the conservation of angular momentum, why the galaxy today is a flat disc that rotates faster.arrow_forwardIf the speed of light is 3.0 × 105 km/s, how many kilometers are in a light-year? How many meters? (Hint: First look up or calculate how many seconds are in a year.)arrow_forwardThink of our Milky Way Galaxy as a flat disk of diameter 100,000 light-years. Suppose we are one of 1000 civilizations, randomly distributed through the disk, interested in communicating via radio waves. How far away would the nearest such civilization be from us (on average)?arrow_forward
