Alien life may not be carbon-based, new study suggests
Self-sustaining chemical reactions that could support biology radically different from life as we know it might exist on many different planets, a new study finds.
UFOs, or Unidentified Flying Objects, and extraterrestrials are perennial favorites in science fiction, but to date there have been no confirmed encounters on Earth. Still, strange sights in the night sky have been attributed to UFOs or aliens over the decades, most famously in Roswell, New Mexico, where many believers claim an alien craft crashed on a farm in 1947. In 2017, the existence of a secret U.S. government program that tracked "UFO" sightings by military pilots, which shut down in 2012, was brought to light in a New York Times report.
