Do you know: what have astrobiologists have found so far?

Here's a more detailed look at some key findings:
1. Evidence of Water and Past or Present Life on Mars:
Past Water:
Evidence suggests Mars was warmer and wetter in the past, with lakes and rivers on the surface.
Current Water:
Scientists have found evidence of water, including frozen water and potentially current flowing water, though in limited quantities.
Potential for Past Life:
Evidence suggests the presence of organic molecules and minerals that hint at the possibility of ancient life on Mars.
2. Discovery of Exoplanets:
Thousands of Exoplanets:
Astronomers have confirmed nearly two thousand exoplanets, with thousands more awaiting confirmation.
Habitable Zones:
Many exoplanets have been discovered within the habitable zones (the "Goldilocks zones") of their stars, where conditions could potentially allow for liquid water and life.
3. Building Blocks of Life in Space:
Organic Molecules:
Astrobiologists have found amino acids and other organic molecules in meteorites and comets, which are fundamental building blocks of life.
Nucleobases:
Nucleobases (the building blocks of DNA and RNA) have been discovered in meteorites and on the asteroid Ryugu, further demonstrating that these molecules are common in space.
Helium Hydride:
SOFIA detected the first known molecule in the early universe, helium hydride.
4. The Search for Life Beyond Earth:
Extremophiles:
Studying extremophiles (organisms that thrive in extreme environments on Earth) helps researchers understand the potential limits of life.
Biosignatures:
The search for biosignatures (signatures of life) in the atmospheres of exoplanets is a key area of astrobiology research.
