Beyond Earth, the general scientific consensus is that the best place to search for evidence of extraterrestrial life is Mars. However, it is by no means the only place. Aside from the many extrasolar planets that have been designated as “potentially-habitable,” there are plenty of other candidates right here in our solar system. These include the many icy satellites that are…

Hostile space weather might not be all bad for exoplanet life
A new study from Northwestern University shows that solar flares – space weather – might not always be as dangerous for life on exoplanets as typically thought. In fact, it might even help astronomers discover alien life on distant worlds. Source: https://earthsky.org/space/hostile-space-weather-might-not-be-all-bad-for-exoplanet-life…
Huge Puerto Rico radio telescope to close in blow to science
The National Science Foundation announced Thursday that it will close the huge telescope at the renowned Arecibo Observatory in Puerto Rico in a blow to scientists worldwide who depend on it to search for planets, asteroids and extraterrestrial life.

Researchers model source of eruption on Jupiter’s moon Europa
On Jupiter’s icy moon Europa, powerful eruptions may spew into space, raising questions among hopeful astrobiologists on Earth: What would blast out from miles-high plumes? Could they contain signs of extraterrestrial life? And where in Europa would they originate? A new explanation now points to a source closer to the frozen surface than might be expected.

Astronomers Find No Signs of Alien Tech After Scanning Over 10 Million Stars
A new large-scale survey of the sky looked into the dark forest of the cosmos, examining over 10 million stars, but failed to turn up any evidence of alien technologies. CNET reports: The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of…
A breakthrough in the search for extraterrestrial intelligence
The researchers called their new analytical technique “a milestone in SETI.” One researcher commented: “We now know that fewer than one in 1,600 stars closer than about 330 light years host transmitters just a few times more powerful than the strongest radar we have here on Earth.” Source: https://earthsky.org/space/analytical-breakthrough-seti-expand-search-200-times…
Is there life below the Martian surface?
Galactic cosmic rays are high energy particles from explosive events like supernovae, zinging through our solar system, constantly bombarding both Earth and Mars. A researcher suggests they supply enough energy to make subsurface life on Mars possible. Source: https://earthsky.org/space/is-there-life-below-the-martian-surface…
