Typically, the search for alien life begins with the search for Earth-like planets - but there may be another class of alien world that is just as conducive to life, a study published in the Astrophysical Journal in August contends. Alien planets may look nothing like Earth The researchers are currently developing algorithms to search through existing telescope data in search of those telltale signatures.
That re-radiated energy would create a distinct wavelength signature that astronomers could detect from Earth, the study authors suggested. To do this, aliens could use high-tech structures called Dyson spheres (giant, energy-siphoning orbs first proposed in the 1960s) to steal energy from the disc of white-hot matter swirling around a black hole’s horizon, then radiate that energy outward into space. Because black holes can radiate up to 100,000 times more energy than a star like our sun, they may make tempting targets for alien civilizations looking to power their interstellar enterprises, the study authors wrote. While alien hunters spend plenty of time searching for habitable planets beyond our solar system, a study published in July in the journal Monthly Notices of the Royal Astronomical Society warns that scientists shouldn’t overlook nature’s most extreme objects: Black holes. However, anyone hoping for an acknowledgement of extraterrestrial intelligence may have been let down when the report failed to link any of the 144 encounters to alien activity. On one hand, the brief, 9-page assessment confirmed that “most of the UAP reported probably do represent physical objects,” which range from birds and balloons to foreign surveillance equipment and top-secret U.S. The report was meant to assess “the threat posed by unidentified aerial phenomena (UAP),” and officially confirmed several UFO sightings that had, until then, only been shared through viral media. In June, the Pentagon released a highly anticipated report detailing 144 UFO encounters between 20. UFOs are real (and the government knows it) Here are 9 things we learned about aliens (and where to look for them) in 2021. But it also gave them answers - from a hotly anticipated Pentagon report on military UFO sightings, to new insights on habitable exoplanets, to the truth about a so-called “alien signal” from the sun’s nearest neighboring star. The year 2021 gave truth-seekers and alien hunters no shortage of mysteries to ponder. A saucer-shaped blob plunging suddenly into the ocean. Strange green lights vanishing into the clouds above Canada. A “ doughnut UFO” in the skies over Switzerland.
