Specifically, I’m curious about: Characteristics of Promising Exoplanets: What are the key characteristics that make an exoplanet a good candidate for supporting life (e.g., size, composition, atmosphere, distance from its star, etc.)? Significant Discoveries: What are some of the exoplanets that have garnered the ...

According to Bhagavad Gita, one of the main instructions to life is to trust the process and focus on the process instead of the results. I believe the core purpose of human life is to just exist. Some days are better than the others. Sometimes things may not go according to your plan, and that’s okay. If we don’t have bad days, how can we appreciate the good days?
So, the main purpose of human beings and mortality in general is to simply be. Sometimes just being there can create a huge shift in evolution. It doesn’t matter what you do or how you live, as long as you don’t give up. The universe will always look out for you if you look out for yourself.

### Dark Matter and Dark Energy
**Dark Matter**:
1. **WIMPs (Weakly Interacting Massive Particles)**: Hypothetical particles interacting via weak nuclear force and gravity. Evidence includes gravitational effects unexplained by visible matter.
2. **Axions**: Extremely light particles potentially solving quantum chromodynamics issues. Indirect evidence from astrophysical observations.
3. **Sterile Neutrinos**: Hypothetical non-weak-interacting neutrinos, supported by some cosmological observations.
**Dark Energy**:
1. **Cosmological Constant (Λ)**: Constant energy density explaining the universe’s accelerating expansion, evidenced by Type Ia supernovae.
2. **Quintessence**: Dynamic field varying over time, with potential but lacking strong observational support.
### Promising Exoplanets and Their Characteristics
**Key Characteristics**:
1. **Size and Mass**: Earth-sized or super-Earths.
2. **Composition**: Rocky planets.
3. **Atmosphere**: Capable of supporting liquid water.
4. **Distance from Star**: Within the habitable zone.
5. **Stellar Type**: Stable, long-lived stars (G-type, K-type).
**Significant Discoveries**:
1. **Proxima Centauri b**: In Proxima Centauri’s habitable zone.
2. **TRAPPIST-1 System**: Seven Earth-sized planets, three in the habitable zone.
3. **Kepler-452b**: In the habitable zone of a Sun-like star.
4. **LHS 1140 b**: Super-Earth with a stable orbit in the habitable zone.
### Detection Methods
1. **Transit Method**: Observes star dimming during planet transit.
2. **Radial Velocity Method**: Measures star’s wobble due to orbiting planets.
3. **Direct Imaging**: Captures images of exoplanets.
4. **Spectroscopy**: Analyzes light for atmospheric composition.
### Future Missions
**James Webb Space Telescope** and **European Extremely Large Telescope** will enhance atmospheric studies and habitable planet identification.
