- Let's assume it took Voyager 1 13 years to reach the edge of solar system at a distance of 40 AU. How fast was voyager 1 traveling in Km/hr?Please help me with this question. A=.2At rest carbon emits a spectral line at 364.0 nm. If this line is observed at 410.0 nm from exoplanet host Helvetio's, how fast is Helvitios moving toward or away from us in km/s?
- If there was a planet orbiting a first generation star, which planet in our solar system would it resemble most? Would it be likely for such a planet to have life?In a globular cluster, astronomers (someday) discover a star with the same mass as our Sun, but consisting entirely of hydrogen and helium. Is this star a good place to point our SETI antennas and search for radio signals from an advanced civilization? Group of answer choices No, because such a star (and any planets around it) would not have the heavier elements (carbon, nitrogen, oxygen, etc.) that we believe are necessary to start life as we know it. Yes, because globular clusters are among the closest star clusters to us, so that they would be easy to search for radio signals. Yes, because we have already found radio signals from another civilization living near a star in a globular cluster. No, because such a star would most likely not have a stable (main-sequence) stage that is long enough for a technological civilization to develop. Yes, because such a star is probably old and a technological civilization will have had a long time to evolve and develop there.When Mars is 90 million km (9 x 10^10 m) from Earth, a) How long would it take for a radio wave from a video camera mounted on the back of a Mars Rover to tell ground control on earth that the Rover is about to go over a cliff? b) How long would it take for a radio signal from Earth to reach the Rover saying "STOP". c) Why do our Mars Rovers have to be "intelligent" enough to figure out how to deal with obstacles themselves?
- The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…The transit method is used to detected exoplanets by measuring the reduced starlight caused by the planet passing in front of its host star. Say you measure multiple transits of the same exoplanet. What does the time in between the transits represent? Group of answer choices - Orbital period - Semi-major axis - Ecentricity - Planet's massFor the following light curve, which of the answers best illustrates the orientation of the exoplanet and its host star during the dip at Time 3? Light curve Time 1 Time 2 Time 3 Time 4 Choose one: А. O C. D. Intensity B.
