Astronomy benefits society and humankind in several important ways: 1) Developments in astronomy help answer fundamental questions about the universe and where we came from. 2) Technologies developed for astronomy have practical applications in daily life, such as X-ray machines used for security screening. 3) Key sectors such as medicine, energy, aerospace, and industry utilize technologies from astronomy, including MRI machines, solar energy monitoring, GPS satellites, digital camera sensors, and computer programming languages.

Today, many people and industries across the globe are affected by developments in
astronomy. Many questions are asked about the universe creation, where we came from among
others. As such, every development in astronomy moves the world closer to the answers of these
queries. In our daily life we utilize developments in technology intended for astronomy. For
example, X-ray viewpoint technology is utilized in X-ray bags belts. In addition, an instrument
known as gas chromatograph developed for a Mars assignment is currently used to scrutinize
luggage for explosives. Other sectors that benefit from astronomy include;
Medicine; a radio astronomer developed aperture synthesis, the process of merging data
from various telescopes to produce one image of the entire collection. Aperture synthesis has
been used by many medical imaging apparatuses, including MRIs and CAT.
Energy; Monitoring of fusion is now done by a technology developed from imaging X-
rays. Binary atomic nuclei combine to create heavier nucleus that could be the explanation for
clean energy.
Aerospace; Space- based telescopes have new defense satellites, that require identical
hardware and technology. Global Positioning System (GPS) satellites depend on astronomical
objects like distant galaxies and quasars to determine exact positions.

Industry; iPhone’s camera is a (CCD) Charge-Coupled Device. This is an instrument
that transforms electrical charge movement into a digital value. Originally, CCDs were
developed for astronomy but they are currently being used in most cell phones, webcams, and
cameras. Additionally, astronomers developed Forth; a computer language established for the
36-foot telescope. Forth is currently used by FedEx to trail packages. Equally, astronomers who
were studying the sun created Kodak film which is currently being used widely by industrial and
medical industries, artists and photographers.
