List three major ideas of astronomy that help frame the context of the search for life in the universe. Describe each one, along with its importance to astrobiology.
The three major ideas of astronomy that frame the context of the search for life in the universe.
Answer to Problem 1RQ
Life can be possible only when the basic requirements of the life are fulfilled on other planets.
Explanation of Solution
The three major ideas of astronomy that frame the context of the search for life in the universe are given below as.
- 1. The universe is vast and old:
In the universe, there are a number of planets or worlds in which life is possible. The universe has many galaxies like “Milky way”, planets, moons, stars, and a solar system. The age of the universe is 13.8 billion years old. At present, there are few planets where life is possible. The old age of the universe means it will take plenty of time to begin life.
- 2. The elements of life are widespread:
The observation of elements indicates the basic requirements of atmosphere that can make the life possible on the planet in a universe. It means life can also be possible on the other planets if the atmosphere is convenient for the growth of life on it.
- 3. The same physical laws that operate on Earth operate throughout the universe:
Some basic law’s which are valid on the earth surface they should also valid in the whole universe then only life can be possible on the other planets.
Conclusion:
Thus, life can be possible only when the basic requirements of the life are fulfilled on other planets.

- Hi can u please solvearrow_forward6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter and with 10 mm thickness. Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function.
