Caltech Researchers Found Aliens but May Be Dead

 As if the stories of Area 51 want to ooze out and show their real existence. Or, one day, a Thanos-like creature will come on Earth, challenging our existence. Many stories have floated regarding the aliens. The speculations regarding the same have created a series of probabilities when humans would interact with the aliens for the first time. However, it is the first time when one can say that there is a concrete and clear picture of the alien civilizations. It is different from the study done a week ago when scientists detected radio emissions from a distant exoplanet. Hence, it is essential to extract crucial inferences from the study.

Latest Development

Researchers from the California Institute of Technology, NASA’s Jet Propulsion Laboratory, collaborated with the Santiago High School to expand the famous Drake Equation. This study presented the outlook of several factors that could establish the norms for habitable or Goldilocks zone. In addition to this, it focused on determining the presence of intelligent life that emerged in our galaxy. According to the observations of the scientists, there are some tenets as the attributes leading to the end of some of the civilizations. These attributes include radiation exposure, a halt to evolution, extreme climate change, war, and technological advancements. However, there are no concrete results that can give suggestions showing that the aliens have gone through self-annihilation. The scientists asserted their hypothesis and inferences giving better results due to the Hubble Space Telescope and Kepler Space Telescope. Both the telescopes provided lots of data about the densities of gases and stars present in the Milky Way galaxy. Apart from this, the telescopes have given details on star formation rates, the occurrence rate of supernova explosions, and exoplanet formation.

Inferences and Results

After the data modeling, collected from the Milky Way over time, the scientists evaluated the probability of life. It observed that there came a peak when there was an emergence of life about 13000 light-years from the galactic center. In comparison to this, Earth is 25,000 light-years away from the galactic center. The results also discussed the human civilization that evolved and developed on the planet’s surface about 13.5 billion years after the Milky Way formed. The scientists have published the results through a research paper, which is waiting for peer reviews.

Drake Equation

Frank Donald Drake, an American astrophysicist, and astronomer devised the Drake equation in 1961. The equation never had the very targeted purpose of formulating the number of civilizations formed after the universe’s evolution. It initiated and triggered the dialogue of search for extraterrestrial intelligence (SETI). This equation summarized the necessary parameters that can consolidate the answer to the existence of other radio-communicative life. The equation skipped the determination to create the vibe to move ahead with the study as the equation has considered many estimations. The factors on which the Drake equation depends are:

• The aggregate rate of star formation in our galaxy
• The fraction of those stars having planets
• The average number of planets that has the potential to support life per star that has planets
• The fraction of planets supporting life and develop life at some instance
• The fraction of planets with life that form intelligent civilizations and life
• The fraction of the intelligent life and civilizations that develop a technology that can release detectable signs of their existence into space (by generating signals or emissions)
• Amount of time taken by the civilizations to release detectable signals or emissions (belonging to the electromagnetic spectrum) into distant space

There has been an issue with quantifying the numerical values of the last four parameters. This issue arises because the range of values has many orders of magnitude.

Conclusion

Though it requires peer reviews, the study has opened the ways to study the presence of extraterrestrial life in distant space. The results may somewhere help humanity to understand the evolution of the universe. Also, it has expanded the potential of the Drake Equation that was in the phase of under-utilization. Even the results can scale-up the capacity-building measures to find more alternatives to detect the presence of aliens outside in space.
