When astronomers announced last month they might have discovered the most promising hints of alien life yet on a distant planet, the rare good news raised hopes humanity could soon learn we are not alone in the universe.
But several recent studies looking into the same data have found that there is not enough evidence to support such lofty claims, with one scientist accusing the astronomers of “jumping the gun.”
The debate revolves around the planet K2-18b, which is 124 light years away in the Leo constellation.
In that paper for the SETI Institute, Kershenbaum and colleagues concluded that animal communication research is the closest we are likely to get to studying extraterrestrial signals, until such signals are actually received.
“Many of the challenges facing SETI research are similar to those already addressed in the investigation of animal behavior, and the evolutionary origins of human language,” they wrote. “Indeed, the evolution of language on Earth may in fact have been driven and constrained by similar principles to those operating on life on other planets.”
The researchers have proposed the establishment of a large cross-species database of communicative signals, made available to all SETI and animal behavior researchers.
This is the weapon that will destroy our solar system in Season 3 of Netflix’s 3 Body Problem: the Dual-Vector Foil. It’s a Dimensional Strike deployed by a super advanced alien civilization called the Singers. Once activated, it expands at light speed, consuming everything in its path. It’s expected to be featured in Season 3 of Netflix’s 3 Body Problem series.

Efforts are underway to search for extraterrestrial life. Imagine how amped this search could be if we applied advanced AI that reaches AGI. Here’s the insider scoop.
Ringworld, by sci-fi author Larry Niven is based on hypothetical megastructures in space called Dyson Spheres but, says Niven, “I took just the equator… the poor man’s Dyson sphere!”

Science students and academics wrote papers about the mathematics and physics of Ringworld after it was published. Larry Niven discusses whether this would happen if Ringworld was published today.

The earliest cells harnessed energy through geochemical reactions, a process that LMU researchers have now successfully replicated in the lab. The earliest ancestor of all life on Earth likely thrived in warm environments, relied on hydrogen for energy, and produced methane as a byproduct. Resear
Launched on March 11, NASA’s SPHEREx space observatory has spent the last six weeks undergoing checkouts, calibrations, and other activities to ensure it is working as it should. Now it’s mapping the entire sky—not just a large part of it—to chart the positions of hundreds of millions of galaxies in 3D to answer some big questions about the universe.
On May 1, the spacecraft began regular science operations, which consist of taking about 3,600 images per day for the next two years to provide new insights about the origins of the universe, galaxies, and the ingredients for life in the Milky Way.
“Thanks to the hard work of teams across NASA, industry, and academia that built this mission, SPHEREx is operating just as we’d expected and will produce maps of the full sky unlike any we’ve had before,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington.
