AS usual I will be posting on the developments with our search for a new home after we blow this one up…..
First, most people interested in planetary exploration knows what is meant by the “Goldilocks Zone”……if you are not one of them then Google is just a click away (look it up)……
But does this “Zone” mean we should think it is a good spot for us humans?
“Any type of planet can orbit in the habitable zone,” but only such Earthlike planets are likely to have liquid water on their surfaces, says astrophysicist Elizabeth Tasker of the Japan Aerospace Exploration Agency. “We all secretly know this, as both the moon and Mars orbit within the habitable zone, but neither have lakeside retreats.”
Why just being in the habitable zone doesn’t make exoplanets livable
Without a proper mode of transportation we humans are stuck on this planet…regardless what we do to destroy it…..why?
Humans will never migrate to a planet outside of Earth’s solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said
Mayor and his colleague Didier Queloz were on Tuesday awarded the Nobel Prize for Physics for their research refining techniques to detect so-called exoplanets.
“If we are talking about exoplanets, things should be clear: we will not migrate there,” Mayor told AFP near Madrid on the sidelines of a conference when asked about the possibility of humans moving to other planets.
“These planets are much, much too far away. Even in the very optimistic case of a livable planet that is not too far, say a few dozen light years, which is not a lot, it’s in the neighbourhood, the time to go there is considerable,” he added.

Beyond our chances of migrating to a new home…..we have other space news…..like researchers have found large structures at the center of our galaxy….
There’s something really, really big in the middle of our Milky Way galaxy — one of the largest structures ever observed in the region, in fact. An enormous pair of bubbles in an hourglass-like arrangement is sending out radio emissions hundreds of light-years beyond our galaxy. Scientists aren’t sure how it formed, but its existence will likely teach us more about the supermassive black hole lurking in the center of the Milky Way.
Then a researcher for SETI has made an interesting claim…..
A physicist who’s on the hunt for extraterrestrial life says there’s a chance that an ancient alien civilization has been spying on Earth for millions of years.
That’s not to say that he’s suggesting they walk among us, but physicist and independent SETI researcher James Benford suggests that aliens could have visited a rock orbiting the Sun in a path similar to that or Earth, according to Live Science. While such an extraterrestrial visit is extremely unlikely, it’s technically within the realm of possibility that alien tech is sitting on one of those so-called co-orbitals, waiting to be uncovered.

Speaking of SETI….after all these years of trying why have we not made contact as of yet?
Didier Queloz, a physicist from the University of Cambridge, was named a co-winner of the Nobel prize in physics on Tuesday for his discovery of the first exoplanet orbiting a sun-like star.
Queloz, who calls himself a “planet hunter,” said following the award ceremony that his work has led him to become “absolutely convinced” that humans will detect alien life in the next 100 years.
“I can’t believe we are the only living entity in the whole universe. There’s just way too many planets, way too may stars … the chemistry that led to life has to happen elsewhere,” Queloz in a talk at the Science Media Center in London on Tuesday.

Now speaking of finding life…..did we find it on Mars in the 70s?
Nasa found evidence of alien life in the 1970s, according to a former senior scientist – and ignored it.
The Viking landers were sent to the Martian surface more than 40 years ago, with the aim of exploring the planet. They included an experiment known as Labeled Release, or LR, which was intended to look for signs of life on the planet.
The results came back in 1976 – and seemed to indicate that something was happening on the surface. Gilbert V Levin – an engineer and inventor who was the principal investigator on the experiment – has now written a long article arguing that those findings were indications of life on Mars, which were ignored by Nasa.
Finally, I mentioned Mars and the rover has discovered something kinda amazing……an ancient oasis….
NASA scientists believe Mars may have had an oasis environment around 3.5 billion years ago, they said Monday. Evidence of ponds scattered across a 100-mile-wide basin called the Gale Crater was found by the Curiosity rover, which discovered mineral salts mixed with sediment in rocks.
Curiosity is currently exploring each layer of the Gale Crater and Mount Sharp to uncover the history of Mars, which scientists think may have gone from an underwater landscape with deep lakes to an oasis-style series of shallow ponds.
“Streams might have laced the crater’s walls,” NASA said Monday, adding “climate fluctuations” changed the environment from wet to desert. Curiosity had previously found evidence of freshwater lakes on Mars, too.
