Moving On Up…To The Stars

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.

My tour of Space News is at an end…..I read and write so you do not have to…..you are welcome.

For your musical enjoyment…..

I Read, I Wrote, You Know

“Lego Ergo Scribo”

Space Sunday

It is that time again…..time for me to bring my readers up to date on the happenings in space and our soon to be active, Space Force.

Most people could care less but I grew up with Buck Rogers, Rocky Jackson, Flash Gordon, etc……so I like space stuff and after all it is my blog so guess what?  Space News!

Lots of stuff to report…..us space nerds are on the job……

Lots of talk about settlers for the Moon……

It’s the year 3000. Having used up all of Earth’s natural resources, humans have become a spacefaring race and established colonies on the moon. Vast, sealed domes cluster across its surface, housing cities populated by hundreds of thousands of people. This cold, gray rock has somehow become humanity’s new home.

Of course, this is pure science fiction. But no vision of the future is complete without an extraterrestrial colony of humans, and since the moon is the closest celestial body to our planet, it’s the easiest to imagine as our futuristic home.

But does this vision align with reality? Will the moon one day be a hot property, and if so, how many people could its unwelcoming landscape realistically support?

https://www.livescience.com/how-many-humans-could-live-moon.html

Then those settlers will reach out to Mars……where will they call home?

The smaller of Mars’ two moons, Deimos, was named after the Greek god of terror — but the way former NASA flight surgeon Jim Logan sees it, Deimos could be a comfort zone for space settlers.

“The Mars-facing side of Deimos is probably the most valuable real estate in the solar system,” Logan, co-founder of the Space Enterprise Institute, said today at Seattle’s Museum of Flight.

Logan laid out his case for Deimos during a conference on space settlement, presented this week by the Space Studies Institute to highlight the late Princeton physicist Gerard O’Neill’s vision for humanity’s expansion into the solar system.

Will we ever find life on Mars?

Nasa is close to finding life on Mars but the world is not ready for the “revolutionary” implications of the discovery, the space agency’s chief scientist has said.

Dr Jim Green has warned that two rovers from Nasa and the European Space Agency (ESA) could find evidence of life within months of arriving on Mars in March 2021.

The ExoMars Rover, which has been dubbed “Rosalind” in memory of British chemist Rosalind Franklin, will search for extra-terrestrial life by drilling 6.5 feet down into Mars’ core to take samples.

https://www.independent.co.uk/news/science/nasa-mars-life-discovery-space-exomars-rover-chief-scientist-jim-green-a9125076.html

Stay on the topic of Mars……what if “life” is found by the rovers now crawling their way across the planet?

Chief scientist at NASA Jim Green believes we’re just years away from finding life on Mars — thanks to the agency’s Mars rover and the European Space Agency’s ExoMars Rover, both scheduled to launch in 2020.

If the missions find life, Green is terrified of the implications.

“It will start a whole new line of thinking,” he told The Telegraph. “I don’t think we’re prepared for the results. I’ve been worried about that because I think we’re close to finding it and making some announcements.”

What about the other neighbor that we do not talk about much….Venus?

It seems that Venus once had a stable environment for awhile…

Venus likely maintained stable temperatures and hosted liquid water for billions of years before an event triggered drastic changes in the planet, according to a new study.

Now, Venus is a mostly dead planet with a toxic atmosphere 90 times thicker than ours and surface temperatures that reach 864 degrees, hot enough to melt lead. It’s often called Earth’s twin because the planets are similar in size. But the modern comparisons stop there.
However, a recent study compared five climate simulations of Venus’ past and every scenario suggested that the planet could support liquid water and a temperate climate on its surface for at least three billion years. Like the other planets in our solar system, Venus formed 4.5 billion years ago.
 
Life and water on Saturn’s moon, Enceladus…….

Scientists just found the most basic ingredients for life bursting from an ocean on Saturn’s moon Enceladus.

A new analysis of NASA data reveals the presence of organic compounds in the plumes of liquid water that shoot into space from the ocean below Enceladus’s icy crust.

These compounds, which carry nitrogen and oxygen, play a key role in producing amino acids ⁠- complex molecules that serve as the building blocks of proteins. Without proteins, life as we know it on Earth couldn’t exist.

Scientists have long suspected that the ocean below Enceladus’s surface could harbour the ingredients for life. Researchers had detected other organic molecules coming from the icy moon before, but this is the first time anyone has detected them dissolved in the water.

That’s critical, since it means the compounds could undergo deep-sea chemical reactions that produce amino acids.

Space For A Saturday

I begin my weekend reporting on stuff most people never think about….SPACE–the final frontier or something like that…..

I had a thought…..we have been “beaming” messages into space for decades…messages of greetings and some on our location and so far no one has answered…..could it be like that bum on the street that you avoid you hear their pleads but pretend not to understand?  That is Earth!

Since a young age I have been interested in Space and the exploration of said domain…..I have the original Buck Rogers and Flash Gordon to help peak my interest…..

The nation’s planetary scientist have been jumping up and down trying to find worlds that could support life……

The hunt for nearby exoplanets has just heated up considerably.

A new instrument designed to find potentially habitable alien worlds in Alpha Centauri, the nearest star system to our own sun, began operations on May 23, project team members announced today (June 10).

The instrument, called NEAR (Near Earths in the Alpha Cen Region), is a thermal coronagraph installed on the European Southern Observatory’s (ESO) Very Large Telescope (VLT) in Chile.

https://www.space.com/alien-planets-alpha-centauri-breakthrough-watch.html

I have heard that could be billions of planets that could support life…that is billions with a “B”…..but are there?

Where is complex alien life hanging out in the universe? Likely not on planets stewing in toxic gases, according to a new study that dramatically reduces the number of worlds where scientists will have the best luck finding ET.

In the past, researchers defined the “habitable zone” based on the distance between the planet and its star; planets that, like Earth, orbit at just the right distance to accommodate temperatures in which liquid water could exist on the planetary surface would be considered “habitable.” But while this definition works for basic, single-celled microbes, it doesn’t work for complex creatures, such as animals ranging from sponges to humans, the researchers said.

When these extra parameters — needed for complex creatures to exist — are taken into account, this habitable zone shrinks substantially, the researchers said. For instance, planets with high levels of toxic gases, such as carbon dioxide and carbon monoxide, would drop off the master list.

NASA and JPL are pushing the limits of exploration these days……

Finally, NASA has said it wants a man on Mars within the next 20 years……and how is that going?

When a female astronaut first sets foot on the Moon in 2024, the historic moment will represent a step toward another NASA first: eventually putting humans on Mars. NASA’s latest robotic mission to the Red Planet, Mars 2020, aims to help future astronauts brave that inhospitable landscape.

While the science goal of the Mars 2020 rover is to look for signs of ancient life – it will be the first spacecraft to collect samples of the Martian surface, caching them in tubes that could be returned to Earth on a future mission – the vehicle also includes technology that paves the way for human exploration of Mars.

That is it for my Space news….hopefully it was informative for those that like and are fascinating by space…….

Please…..watch this “SPACE”.  (I could not resist)

May The Fourth Be With You–2019

Saturday….MoMo has hunted down a mole, dug it up and is now playing with it….

Apparently it just pissed her off….now she is just pissed at me for spoiling her fun……

Onward……

Since today is May the Fourth I feel compelled to post on space and a galaxy far far away ………..it is only a matter of time until we discover life on another planet….


Extraterrestrial life, that familiar science-fiction trope, that kitschy fantasy, that CGI nightmare, has become a matter of serious discussion, a “risk factor”, a “scenario”.

How has ET gone from sci-fi fairytale to a serious scientific endeavour modelled by macroeconomists, funded by fiscal conservatives and discussed by theologians?

Because, following a string of remarkable discoveries over the past two decades, the idea of alien life is not as far-fetched as it used to seem.

Discovery now seems inevitable and possibly imminent.

https://theconversation.com/why-the-idea-of-alien-life-now-seems-inevitable-and-possibly-imminent-115643

This seems to be the consensus among planet scientists…..they are trying desperately to find that life and to justify the money spent in that pursuit.

Of course we could all just sit back and buy into the “Ancient Alien” BS….for me I prefer a more scientific approach than some silly leap of faith from a bunch of deluded and washed up pundits.

Then there is Mars……I read a piece about human life on Mars after colonization…..

A city on Mars could provide the first-ever truly blank slate to organize a new kind of economy.

While attempts to re-organize the means of production are as old as humankind itself, these experiments have always been limited to some extent by the economic systems that came before. People can only change so much so fast. Space exploration, and the establishment of new colonies, may be humanity’s first shot at creating an economy from the ground up. Its first settlers could opt for pure socialism — where all ownership was shared — just as easily as they could establish a city that enshrines property rights so much there are no other laws at all. The dusty red surface, in other words, will provide us with what could be the first history-free moment to start anew.

“To an economist, this is perhaps the most exciting thing about space settlement!” Matt Weinzierl, a professor at Harvard Business School who has written about the economics of space, tells Inverse. With Jeff Bezos and Elon Musk possibly on the verge of opening up space to society, a prospect that has venture capitalists excited, this developing area of research has started to grapple with how economics may shift as humans explore beyond Earth.

https://www.inverse.com/article/55060-a-mars-colony-could-be-humanity-s-best-shot-at-a-purely-designed-economy

That is an ambitious and glowing prospect for a Mars colony…….and then it may not happen as quickly as some have predicted…..

An independent report concluded that NASA has no chance of sending humans to Mars by 2033, with the earliest such a mission could be flown being the late 2030s.

The report, while completed prior to the March 26 speech where Vice President Mike Pence directed NASA to return humans to the moon by 2024, does offer insights into how much a lunar return might cost and how it fits into long-term plans to send humans to Mars.

NASA contracted with the Science and Technology Policy Institute (STPI) to prepare the report, which Congress directed NASA to perform in the 2017 NASA authorization act. That bill called specifically for a technical and financial assessment of “a Mars human space flight mission to be launched in 2033.”

https://www.space.com/human-mars-mission-is-not-feasible.html

It is possible that a Mars colony will have to wait awhile longer.

There is my round-up from a galaxy far far away……

May the Fourth be with you!

By The Way….MoMo is now onto a new adventure.

Have a good day and see you later….chuq
