☆ Dyson spheres: Could alien megastructures exist in the Milky Way? Scientists found 7 places to look

Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. If Dyson spheres really exist, what could they be used for? “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. However, he added, the radiation fingerprint of the seven Dyson sphere candidates might be explained by natural phenomena as well.

But there is a possibility that residual underground lava tubes may still exist. HUM Images/Getty ImagesIf these lava tubes are anything like Earth's, they could be the perfect place for astronauts to hunker down during their stay on Mars. It's unclear if lava tubes on Mars would also be this warm — it's not a stretch to imagine, just a challenge to confirm. But to be clear, just because there could be life in these pits, doesn't mean Mars definitely hosts extraterrestrials. "This is a good place to look, but we don't know if there's life on Mars at all," Johnson said.

The Harvard professor's research is bankrolled by tech tycoons "pissed off" at academia's dogma. But this boundary-pushing is exactly why he's backed Loeb's research. AdvertisementDesch, the astrophysicist from Arizona University, posted a critique of Loeb's work on arXiv alleging "multiple fatal flaws with the manuscript's arguments." Asked whether he no longer believes in a possible technological origin for the meteor, Loeb said they need to investigate further. As he plans more extravagant expeditions to prove the origin of the interstellar meteor, Loeb likens his critics to crows pecking at the neck of an eagle.

CNN —Scientists may have pinpointed a massive, oddly shaped volcano taller than Mount Everest on the surface of Mars — and it has been hiding in plain sight for decades, according to new research. Some of the largest volcanoes on Mars lie relatively close to the proposed “Noctis volcano.” Shown here: 1) Olympus Mons, the tallest known volcano in our solar system. This NASA visualization of the Tharsis rise shows Olympus Mons, Tharsis Montes, Noctis Labyrinthus, and Valles Marineris.

CAPE CANAVERAL, Fla. (AP) — Astronomers have found the best evidence yet of a vast, young ocean beneath the icy exterior of Saturn’s Death Star lookalike mini moon. Barely 250 miles (400 kilometers) in diameter, the heavily cratered moon lacks the fractures and geysers — typical signs of subsurface activity — of Saturn’s Enceladus and Jupiter’s Europa. Photos You Should See View All 45 ImagesThe ocean is believed to fill half of Mimas’ volume, according to Lainey. But at the seafloor, he said the water temperature could be much warmer. Co-author Nick Cooper of Queen Mary University of London said the existence of a “remarkably young” ocean of liquid water makes Mimas a prime candidate for studying the origin of life.

☆ Saturn’s ‘Death Star’ moon is hiding an internal ocean, scientists say

CNN —Astronomers have uncovered additional evidence that one of Saturn’s smallest moons, Mimas, is hiding a global ocean beneath its icy surface. Discovered in 1789 by English astronomer William Herschel as a tiny dot near Saturn, Mimas was first imaged from space by the Voyager probes in 1980. Craters cover the surface of Mimas, but the largest one is 80 miles (about 130 kilometers) across and causes the moon to resemble the Death Star from the “Star Wars” films. But Saturn’s Enceladus appears younger because active geysers have contributed to resurfacing, or depositing of new, fresh material on that moon’s surface. “Mimas certainly demonstrates that moons with old surfaces can be hiding young oceans, which is pretty exciting,” Rhoden said.

Efforts to detect alien technological signatures previously have focused on a narrowband radio signal type concentrated in a limited frequency range or on single unusual transmissions. The search involves a frequency range covering a bit less than a tenth the width of an average FM radio station. "Aliens may possibly use such beacons for galaxy-wide communications, for which the core of the Milky Way is ideally placed. The scientists in the various monitoring efforts passively scan for signals of alien beings and do not actively send their own signals advertising our presence on Earth. "In my personal opinion, as a relatively young species in the grand cosmic scale, it would be prudent for us to focus on listening and investigating before embarking on deliberate transmissions," Gajjar said.

Extraterrestrial life could exist, but mysterious objects in the sky aren't evidence of aliens. Scientists have thought they were close to discovering alien life a few times — none of it via UFOs. As the US discovered a flurry of UFOs — officially called "unidentified anomalous phenomena," or UAPs — in early February, Google searches for "extraterrestrial life" and "are aliens real" spiked. There have been incidents in the past where some researchers thought they'd come close to discovering signs of alien life — or even extraterrestrial intelligence — but none were UFOs. They dubbed the first interstellar object 'Oumuamua, which is a Hawaiian term meaning "a messenger from afar arriving first."
