NASA says Voyager 2 may be nearing interstellar space

  NASA says Voyager 2 may be nearing interstellar space Voyager 1 could soon welcome its twin to the space outside our solar system.Voyager 2 has been traveling through the heliosheath, the outermost layer of the heliosphere, for over a decade. NASA describes the heliosphere as a "vast bubble around the Sun and the planets dominated by solar material and magnetic fields.

A Nasa scientist says Earth may have already been visited by extraterrestrials - but that humans may not have noticed.

In a research paper, Silvano P Colombano, a computer scientist at NASA Ames Research Centre and a professor, suggests that aliens may look vastly different than the expectations that humans have of them - such as being carbon-based organisms - which would allow them to remain undetected.

“I simply want to point out the fact that the intelligence we might find and that might choose to find us (if it hasn’t already) might not be at all produced by carbon-based organisms like us,” Colombano wrote in the paper.

Silvano Colombano, a NASA scientist for Intelligent Systems Division, has urged the scientific community to broaden their views of potential alien lifeforms 04/12 20:01 NASA Scientist Says 'Tiny Super-Intelligent' Aliens Might Have Visited Earth . Confirmation instructions have been sent to.

According to Colombano, to advance in the search for extraterrestrial life, scientists must “revisit our most cherished assumptions” and consider the idea of different characteristics - as well as the possibility that interstellar travel is already feasible for extraterrestrials.

“The size of the ‘explorer’ might be that of an extremely tiny super-intelligent entity,” he hypothesised. “If we adopt a new set of assumptions about what forms of higher intelligence and technology we might find, some of those phenomena might fit specific hypotheses, and we could start some serious enquiry.”

Colombano also suggests that it is worth re-considering what civilization may actually look like when scanning the universe and “considering further that technological development in our civilisation started only about 10,000 years ago and has seen the rise of scientific methodologies only in the past 500 years” when doing so - as humans may have a “real problem predicting technological evolution even for the next thousand years, let alone six million times that amount.”

Additionally, Colombano suggests the reasons UFO phenomena may have gone unnoticed or overlooked in the search for extraterrestrial intelligence are because, in addition to assuming a low likelihood of extraterrestrial travel and a high likelihood of hoaxes, the subject is generally avoided by the scientific community.

The paper, which was submitted as part of SETI’s Decoding Alien Intelligence workshop, concludes by proposing a “more aggressive” approach to future SETI exploration by considering such things as a “willingness to stretch possibilities as to the nature of space-time and energy” and speculation about “what kinds of societies we might expect to find.”

NASA's new Mars lander has taken a selfie from above, using a camera on its long robotic arm. The InSight lander snapped a series of pictures that NASA turned into a stunning mosaic released Tuesday. InSight landed on Mars on Nov. 26. In the two weeks since, scientists are thrilled to find the area in front of the spacecraft pretty much free of rocks, hills and holes. That should make it a safe place for InSight's two geology experiments, which will be moved to the ground in the coming weeks. Lead scientist Bruce Banerdt of NASA's Jet Propulsion Laboratory says the red sandy expanse might seem "pretty plain" — if it weren't on Mars.
