Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.
Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.
“Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”
However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids |

| A job for the Webb space telescope

We got 53 candidates for anomalies that cannot be well explained, but cant say that all of them are Dyson sphere candidates, because thats not what we are specifically looking for, said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazos model to see how many tie into it.

You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere, she added. To do so you need to also rule out that its not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy so its a win-win.
Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASAs James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? If you picture ourselves having as much energy as the sun is providing every second, we co |
