Hawking's Aliens --"I Am More Convinced Than Ever That We are Not Alone" (WATCH/LISTEN)

 

Arrival

 


"As I grow older I am more convinced than ever that we are not alone. After a lifetime of wondering, I am helping to lead a new global effort to find out," Stephen Hawking said in a video. "The Breakthrough Listen project will scan the nearest million stars for signs of life, but I know just the place to start looking. One day we might receive a signal from a planet like Gliese 832c, but we should be wary of answering back," Hawking added.

NASA Scientists: "Pluto Flybys Point To Ingredients for Life Below Its Surface" (VIDEO)

 

Pluto2


Pluto has long been viewed as a distant, cold and mostly dead world, but the first spacecraft to pass by it last year revealed many surprises about this distant dwarf planet. The data from the New Horizons flyby finished downloading to Earth in October, and while it will take many years for scientists to complete their inventory and model the results, early studies offer intriguing hints of its complex chemistry, perhaps even some form of pre-biological processes below Pluto’s surface. Complex layers of organic haze; water ice mountains from some unknown geologic process; possible organics on the surface; and a liquid water ocean underneath — all of these features point to a world with much more vibrancy than scientists have long presumed.

“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”

NASA LIVE HEADLINE: Announces Discovery of New TRAPPIST-1 Red-Dwarf Solar System With 7 Earth-Sized Planets --"Best Chance Yet of Alien Life"

NASA has just announced discover new solar system with ‘best chance yet of alien life’ .Life may have evolved on at least three planets in a newly discovered solar system just 39 light years from Earth, NASA has announced.​ Astronomers have detected no less than seven Earth-sized worlds orbiting a cool dwarf star known as TRAPPIST-1. The six inner planets lie in a temperate zone where surface temperatures range from zero to 100C. Of these, at least three are thought to be capable of having oceans, increasing the likelihood of life. No other known star system contains such a large number of Earth-sized and probably rocky planets.

There is an interesting paper with press conference participants Sara Seager and Michael Gillon among the authors in 2015 "Hubble Space Telescope search for the transit of the Earth-mass exoplanet Alpha Centauri Bb" that says results from exoplanet surveys indicate that small planets (super-Earth size and below) are abundant in our Galaxy. However, little is known about their interiors and atmospheres.

NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious dark side of  the universes known as dark matter. The signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

A clue to the discovery NASA will reveal  tomorrow might well be the presence of Michael Gillon, astronomer at the University of Liege in Belgium; Sean Carey, manager of NASA's Spitzer Science Center at Caltech/IPAC; and  Sara Seager, professor of planetary science and physics at Massachusetts Institute of Technology. All three have been intensely focused on the discovery of new Earth-like planets in the Alpha Centauri Star System.

The Brightest, Most Distant Pulsar in the Observable Universe --"1,000 Times More Luminous Than Thought Possible"

“This object is really challenging our current understanding of the ‘accretion’ process for high-luminosity stars,” says Gian Luca. “It is 1000 times more luminous than the maximum thought possible for an accreting neutron star, so something else is needed in our models in order to account for the enormous amount of energy released by the object.” The scientists think there must be a strong, complex magnetic field close to its surface, such that accretion onto the neutron star surface is still possible while still generating the high luminosity.

"SMASH" --An Amazing New Theory of the History of the Universe (From Big Bang to the Present Day)

“Overall, the resulting description of the history of the universe is complete and consistent, from the period of inflation to the present day. And unlike many older models, the individual important values can be calculated to a high level of precision, for example the time at which the universe starts heating up again after inflation,” emphasises Andreas Ringwald at DESY, a research institute in Hamburg Germany for high-energy and particle physics.
