Barry’s Gleanings: Planets, Planets . . .

“Science-fiction writers have been dreaming up alien planets for decades . . . [S]cience had to wait until 1992 for proof that such planets did exist .. . Thanks to a combination of ground-based telescopes and planet-hunting satellites, particularly one called Kepler, which was launched in 2009, more than 3,500 such worlds are known.

Unlike their depiction in fiction, reasonably few are much like Earth . .. And almost all are far, far away . . . .

By April 2016, Kepler was about 100 million miles from Earth.

From 2017, though, that will change.  In December a successor to Kepler, called TESS (for Transiting Exoplanet Survey Satellite), will be launched into orbit.  It is designed to survey the entire sky, looking for the sorts of exoplanets that are of most interest to humans – ones that are small (like Earth), rocky (like Earth), and relatively close by . . . . The new satellite should spot about 3,000 planets.

In August 2016, scientists announced the discovery of an Earth-like planet orbiting Proxima Centauri, which, at 4.25 light-years away, is the closest star to the Sun.

Yuri Milner, a Russian billionaire and physicist . . . is already working with Stephen Hawking, a British theoretical physicist, on plans for a tiny, laser-propelled probe that could cover the distance in about 20 years”  (139).

From “Planets, planets everywhere” by Tim Cross in The Economist: The World in 2017. 

Our fiction and our scientific facts are changing  — and all most interesting.

About reneeriley

Our blog was begun as a way to share our experiences in China. From August 2010 to July 2011, my husband, Barry Kristel, and I were at our University of Hawaii Maui College sister school, Zhejiang Agriculture and Forestry University in Lin'an, China, a city considered rural because it has only 500,000 people! We had a wonderful time. Then in February 2012, we returned to teach this time at our other sister school, Shanghai Normal University, in a city of over 21 million people. We've made many discoveries. Did you know that now Chinese girls, at least the ones who go to university, for the most part feel they are luckier than the Chinese boys? Did you know that Shanghai saved over 20,000 European Jews during WWII? Do you know how Chinese university students would deal with problems that come up in Dear Abby letters? What's it like to be on the Great Wall of China? Do you know how many Chinese girls had their feet bound and why? And we have recipes from many of the places we've visited. Among others, you can find instructions on how to fry cicadas from one of my ZAFU students and how to make chocolate-Kahlua waffles from my brother Mike in Gainesville. You can also look back to our earliest entry to see what we experienced in Oaxaca, Mexico, in 2006 during the mainly peaceful six months of protest until the Mexican government sent in the troops. Between our stays in China, Barry and I have been on the Mainland U.S. visiting family, friends and Servas hosts as we traveled home to Maui. We share those experiences too. Welcome to our blog! Aloha and Zài Jiàn, Renée and Barry

    That’s actually interesting, but, sincerely, I do believe that, if we colonize other planets, we’ll repeat same mistakes and mass destruction – even of ourselves – that we’re doing here in Earth…sadly, but that’s our reality. And we should change our habits, or, at least, try to change them, before we decide whether we should colonize other planets, that’s, IF they have same aspects Earth has. I do believe that, when God put us in Earth, He did it on an attempt we’d care about our planet, but, sadly, we don’t seem to take certain issues such as global warming and pollution as seriously as they should be treated and we do extinct species who do – or rather, did – an important role on ecosystems, which is invariably leading to planet’s destruction. God might be sad with wha’ are we doing to our planet, but He gives us second chances daily, so, let’s try taking care of our planet, or at least,try to, before we destructs it? Are y’all already doing yuh part in global warming and pollution control and awareness, apart from taking care of planet on other ways? If yah, how?
    Hope y’all are good,
    R
