Saturn’s Moon, Enceladus, Is Our Closest Great Hope For Life Beyond Earth

“Cassini provided scientists with a wealth of data about Enceladus’ surface and the composition of its powerful plumes. This data showed evidence of a deep saltwater ocean with an energy source beneath Enceladus’ surface. The presence of water, warmth, and organic molecules are the necessary requirements for sustaining life as we know it. Water is proven to exist, while the tidal forces from Saturn provide the necessary heat. Based on observations of other bodies in the Solar System, Enceladus likely contains the raw ingredients for life as well. The suspected existence of all three hints at the possible presence of the precursors to amino acids in this vast subsurface ocean. Should we find extraterrestrial life on Enceladus – or in the geyser-like plumes erupting into space – the implications are almost incomprehensible.”

When you think about life beyond Earth, you likely think of it occurring on a somewhat Earth-like planet. A rocky world, with either a past or present liquid ocean atop the surface, seems ideal. But that might not even be where life on Earth originated! Deep beneath the Earth’s surface, geologically active hydrothermal vents currently support diverse colonies of life without any energy from the Sun. Saturn’s icy moon, Enceladus, has a subsurface ocean unlike any other world we’ve yet discovered. The tidal forces of Saturn itself provide the necessary heat, and also create cracks in the Enceladean surface, enabling massive geysers. This subsurface ocean rises hundreds of kilometers high, regularly resurfaces the world with a coat of fresh ice, and even creates the E-ring of Saturn. But most spectacularly, it may house actively living organisms, and could be the next-best world for life, after Earth, in the Solar System today.

Artificial intelligence: don’t fear AI. It’s already on your phone – and useful

See on Scoop.it - Knowmads, Infocology of the future

When Joe Weizenbaum found his secretary using a computer program he had created, he was so upset he devoted the rest of his life to warning people not to use its technology. The program was “Eliza”, which gives a passable imitation of a nondirectional psychiatrist; you type sentences such as: “I wonder what I should write,” and it replies :“What answer would please you the most?” (You can try a version at psych.fullerton.edu/mbirnbaum/psych101/Eliza.htm). Weizenbaum’s distress came because he had written Eliza as an experiment, to see whether he could simulate “artificial intelligence” in a question-and-answer system by parsing sentences and throwing relevant bits back at the questioner. But his secretary saw it as real, and asked him not to intrude on “sessions”; Weizenbaum saw this as an omen that we would be too easily fooled into trusting machines.

Could the demand for a cure to autism be coming exclusively from neurotypical parents given the existence of advocates against a cure who...

It could be that most of The Demand for a Cure for Autism comes from Neurotypicals. Answer by Zem Jones:

To "cure" me would be to change the person I am into someone I don't recognise. To "cure" some of the issues caused by my autism, such as my heightened anxiety, or hyperacusis, or my bowel problems, would be a blessed relief. People who want a cure for autism do not understand what needs curing and generally they must be people who don't know autism from the inside, or people who have been taught that it is autism that is the whole problem when it is probably a sensory difference or comorbid condition or combination of them that causes the discomfort and distress they see on the outside. I have a friend who has a child with Kanner's autism. He also has epilepsy. She tells me that when his epilepsy is under control he thrives as if his presentation was more like Asperger's rather than Kanner's but she always knows when a big fit is coming because he regresses into classic autistic behaviours for days beforehand. To me this says the autism is not the problem for him and I suspect the same is true for most children diagnosed with classic autism - if they could tell us what the problem really is and we could cure that then how much better would their lives be? I think people who want to cure the autism itself don't even know what autism really is.

Astronomers using NASA’s Spitzer Space Telescope have detected arrangements of carbon atoms known as buckyballs outside of the Milky Way galaxy for the first time. Sir Harry Kroto of Florida State University, who won a Nobel Prize for discovering buckyballs, says life may even owe its existence to the atom “cages” which resemble soccer balls. The discovery of buckyballs in the Small Magellanic Cloud suggests that these complex molecules may be present around many stars where it was predicted they would be unlikely to form. Extensive follow-up studies using ground-based telescopes will be used to establish the conditions helpful for the formation of buckyballs in our galaxy and other galaxies.

At Least 94 More Exoplanets were just recently discovered by Astronomers and Astrophysicists using NASA's Kepler Space_Telescope.

Scientists discover almost 100 new exoplanets

“We started out analyzing 275 candidates of which 149 were validated as real exoplanets. In turn 95 of these planets have proved to be new discoveries,” said American PhD student Andrew Mayo at the National Space Institute (DTU Space) at the Technical University of Denmark.

Scientists Discover Almost 100 New Exoplanets

“This research has been underway since the first K2 data release in 2014.”

Mayo is the main author of the work being presented in the Astronomical Journal.

The research has been conducted partly as a senior project during his undergraduate studies at Harvard College. It has also involved a team of international colleagues from institutions such as NASA, Caltech, UC Berkeley, the University of Copenhagen, and the University of Tokyo.

This is The Smallest Sized EXOPLANET Discovered by NASA's TRANSITING EXOPLANET SURVEY SATELLITE so far!

NASA's TESS mission finds its smallest planet yet

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star. The planet, called L 98-59b, marks the tiniest discovered by TESS to date.

Two other worlds orbit the same star. While all three planets’ sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets – that is, planets beyond our solar system – that have the best potential for this kind of follow-up.

“The discovery is a great engineering and scientific accomplishment for TESS,” said Veselin Kostov, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the SETI Institute in Mountain View, California. “For atmospheric studies of small planets, you need short orbits around bright stars, but such planets are difficult to detect. This system has the potential for fascinating future studies.”

A paper on the findings, led by Kostov, was published in the June 27 issue of The Astronomical Journal.
