Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.

Infrared spectroscopy helps to identify the atoms and molecules in the object.

The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.

The Doppler shift enables astronomers to discover extrasolar planets.

As a planet orbits its star, the star is alternately moving away from or toward us.

Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

One of the most important scientific discoveries was penicillin. Research the discovery of penicillin, what produces this drug,
artcher [175]

Answer:

It is essentially a broth culture filtrate of the penicillium mould.

Explanation:

  • Alexander Fleming invented penicillin an antibiotic in 1928. These have been rated as the most important scientific discovery, being among the first antibiotics to be effective against bacterial infection.
  • Penicillin belongs to different families that are selective against a large variety of bacteria.
  • In fact, this antibiotic was discovered by fleming and accident in which he left a platter containing staphylococci open and was contaminated by green mould. There was an area of inhibited bacterial growth around the mould from which he inferred that the mould produced a material that inhibited bacterial growth. This was found to be a penicillium mould through further study.
  • I assume penicillin is the most significant discovery so far because it was the first antibiotic ever discovered against bacterial infection in the absence of any drug.
