Q. From which space probe scientists have found evidences indicating building blocks for life on earth may have come from outer space?- Published on 30 May 16a. Rosetta
b. Cassini
c. MOM
d. None of the above
ANSWER: Rosetta
Scientists have found further evidence supporting the theory that building blocks of life may have come to earth from outer space
- Instruments used abroad the European space probe Rosetta detected glycine and phosphorous in the dusty world around the comet
- Glycine is an amino acid which is one of the molecules needed to make proteins while phosphorous is needed for DNA and cells
- Presence in the coma enveloping comet 67P indicates that comets delivered key molecules for prebiotic chemistry through the solar system and in particular, to the early Earth
- Scientists also said adding a high concentration of these molecules to bodies of water could have produced the primordial soup giving birth to life on the planet more than 4 billion years ago.
