News from Space: First Earth-Sized Exoplanet Found!

kepler78bFor the past three and a half years, the Kepler space telescope has been hurtling through space and searching the Milky Way for signs of of other planets orbiting distant stars. In that time, Kepler has identified many Earth-like exoplanets, many of which reside within our own stellar neighborhood. However, it has found only one planet in recent months that is Earth-sized.

That planet is known as Kepler-78b, the existence of of which was recently verified by NASA scientists at Cape Canaveral. Of all the planets discovered beyond our Solar System, this one is both rocky in composition and weighs in at roughly 1.2 times Earth’s mass. Beyond that, however, the similarities between this planet and our own end.

Basically, this means that Kepler-78b is thirty to forty-five times closer to its Sun than Mercury is to ours, and experiences a full year in under nine days. This makes Kepler 78b an extremely hostile environment, unsuitable for life as we know it.

Andrew Howard, of the University of Hawaii at Manoa’s Institute for Astronomy and the lead author on one of two papers published in Nature magazine about the discovery of the new planet, said in recent webcast:

We’ve been hearing about the sungrazing Comet ISON that will go very close to the Sun next month. Comet ISON will approach the Sun about the same distance that Kepler-78b orbits its star, so this planet spends its entire life as a sungrazer.

Kepler78b1A handful of planets the size or mass of Earth have been discovered, but Kepler-78b is the first to have both a measured mass and size. At 1.2 times the size of Earth with a diameter of 14,800 km (9,200 miles), astronomers say it has a density similar to Earth’s, which suggests an Earth-like composition of iron and rock. Its star is slightly smaller and less massive than the sun and is located about 400 light-years from Earth in the constellation Cygnus.

Verification of the planet’s existence and characteristics was made by two independent research teams that used ground-based telescopes for follow-up observations. The team led by Howard used the W. M. Keck Observatory atop Mauna Kea in Hawaii. The other team led by Francesco Pepe from the University of Geneva, Switzerland, did their ground-based work at the Roque de los Muchachos Observatory on La Palma in the Canary Islands.

According to current theories of planet formation, it couldn’t have formed so close to its star, nor could it have moved there. Given that its star would have surely been larger when the system was in formation, Kepler-78b’s orbit would have put in inside the swollen star. Hence, the planet’s existence is an enigma.

To make matters worse, Kepler-78b is a doomed world. Gravitational tides will continue to pull Kepler-78b even closer to its star, and eventually it will move so close that the star’s gravity will rip the world apart. Theorists predict that the planet will vanish within three billion years. And while this may sounds like an eternity to us, in astronomical terms it represents a life cut short.

Repitching an Old Idea: The Council of Muraqaba

world_religionsHey folks! A lot of things have got me thinking about another old idea that I think needs to be updated and brought forward. This one comes from many years back, roughly 2007, when I was working on the series of short stories that make up my Legacies series. As one of several ideas I was working with back then, it kind of fell by the wayside as I busied myself with writing the others – Flight of the Icarus, Eyes in the Dark, Turncoats, Vega Rising.

Eventually, as with many ideas us indie writers come up with, it lost my interest after lingering so long in my Inbox. But after a few conversations with respected colleagues, I found myself thinking about it again and looking to update it, add a new spin, and just generally give it another try. The story, in its updated version, is called The Council of Muraqaba, and it concerns humanity’s efforts to create a universal religion in the future.

world_religions_distWhen I first came up with the idea for a universal faith as part of my Legacies universe, I was still in my Frank Herbert phase and borrowed many crumbs off his table. His own notes in Dune about the Orange Catholic Bible and the Commission of Ecumenical Translators that created it really inspired me, and it put me in mind of the World Religions class I took in high school, which just happened to be one of my favorite subjects.

In 2007, the short story that was to feature the attempts to create this religion was more of an original idea, at to me. I envisioned a world where the council behind the religion’s creation established a permanent seat where matters of interfaith exchanges could take place, and where research into what made them all tick could be done and universal principles uncovered.

world_religions_popThis seemed like a timely idea to me given just how controversial, central, and daunting the issue of faith continues to be in our world today. Between people who demand that others conform to their religion to those who condemn religion of any kind, and from those who use it justify violence and persecution to those who blame it for the problems of entire regions of the world (i.e. Africa, the Middle East and Islamophobia), it’s almost inescapable.

Because of this, and because of the way humanity has a hard time outgrowing old habits, I figured a story that dealt with humanity’s continued difficulties with religion and sectarian differences should be included in my Legacies bundle. But as I said, I’ve been updating the idea a bit thanks to some conversations with friends which raised some poignant issues about the future, and thanks to some research about what the future is likely to hold…

gliese-581.jpgWhat I am envisioning now is a world where a group of mystic settlers originally established a colony on Gliese 581 d – aka. Muraqaba – in the hopes of creating a community where traditional faiths could still be practiced, free from the fear of ongoing progress and how it was leading many to conclude that religion was obsolete. Named after the Sufi practice of meditation, they sought to live in peace and practice freely, and were on guard against what they saw as “needless augmentation”.

In time, this community expanded and became dedicated to finding a way to bring all faiths together and finding common ground not just between religions but between faith and science itself, something which still eluded people in this age. Eventually, this led to the creation of the Council of Muraqaba, a permanent institution where scholars and religious authorities could meet, discuss, and network with people in the universe at large to iron out matters of spirituality.

matrix_cyberspaceIronically, the Council became a hub for some of the most advanced interstellar learning and education since people who were light years away from each other could communicate using a quantum array that allowed FTL communications to take place. The experience of this is central to the story, as it provides a sort of mystic mental sharing that is akin to a spiritual connection, emotions and thoughts shared instantaneously between people.

And of course, there will be a twist as a regular day at the Council turns into something sinister. Just because the local inhabitants have succeeded in creating a dialogue with the universe at large doesn’t mean that everyone is interesting in what they have to say. And some people are concerned that all this “common ground” stuff is eroding the things that make their faith special and want it to end.

And some… some are interested in what the Council has to say for reasons that go far beyond matters of faith! Be sure to check it out, as I think this story just might be one of my more inspired pieces of writing. And my thanks once again for Khaalidah for turning on the light in my head. There’s a reason I call you “Lady Inspiration” you know 😉
