What technology are scientists using to search for other planets? how are they using this technology to identify other planets?

They use radiometry and pyrometry

NASA uses the Transiting Exoplanet Survey Satelite (TESS) telescope that employes this technology

This telescope measures the brightness/luminosity of stars. When this brightness drops regularly, every more or less in the same number of years, then there is the likelihood of a planet orbiting the star. The dip in brightness of the star is directly proportional to the size of the planet and the distance between the star and the orbiting planet.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
