From My Nature Journal: So What’s a TCO?

And now, from the 'It Might Give a Whole New Meaning to the Phrase New Moon' category, it appears that our earth has a new traveling partner, at least for a while.

I saw in the news earlier this week that a second moon has been discovered in the Earth’s gravitational system, a discovery at the Catalina Sky Survey that took place only two weeks ago, February 15. What’s the Catalina Sky Survey? According to the Internet, it's "a NASA-funded project supported by the Near Earth Object Observation Program (NEOO) under the Planetary Defense Coordination Office (PDCO), based at the University of Arizona's Lunar and Planetary Lab in Tucson, Arizona." All those abbreviations make it sound pretty important. Who knew? Essentially, their job is to discover comets and asteroids. And since at least one of those programs is there to recognize threats to our earthly existence, I guess that's a good thing, though I often think that would be a way better way to go than our destroying ourselves (either militarily or environmentally), which we sure seem bent upon sometimes...


The article's title is what grabbed my attention: Earth Captures Object Temporarily, Possible Mini-Moon. It's not very large, this object, somewhere only between six and eleven feet in diameter, so it can hardly be compared to Ol' Luna, but it's finding a chaotic path through our gravitational system, influenced by both Earth's and moon's pulls. It has even been given a name. 2020 CD3. Cute, hey> Leave it to NASA. Additionally and amusingly, we find it has been hanging around the vicinity for two or three years by now, which also gives us a great boost of NASA confidence. Lots of asteroids actually fly by Earth, though, and the only reason it's being considered a mini-moon at this point is that it has been hanging around so long. But astronomers feel it will eventually 'tire' of sticking around here and get back within a few weeks to its heliocentric (sun-centered) orbit, being flung somewhat differently as a result of its 'close encounter of the Earth kind.' 

This kind of thing is not that rare. It happened about thirteen years ago as well, an object adoringly named 2006 RH120, rotating Earth for eight months or so before it was jettisoned. But here’s the interesting thing to me: this phenomenon has a name, and that’s where my title comes in. In the astronomy field, these bodies are called Temporarily Captured Objects, or TCOs.

Temporarily captured objects. As usually happens with this blog, it’s a phrase like that one that will seize my interest and draw me to a faith parallel. In the spiritual realm, there are a lot of people like this, people whose spiritual attention is gotten, usually in some kind of crisis or time of need, but whose attention is only temporary. I was fascinated by the stories that came out of Hawaii back in January of 2018 when they had gotten that North Korean missile scare, tales of all kinds of people turning to prayer who had never prayed in their lives, prayer to a God they had not even believed had existed. And I prayed for those people at that time that such a thing might actually cause them to stop and think: why did I pray to a God I did not even think was there? But that’s extreme, that sort of Armageddon-ish fright. I think people do this all the time, God temporarily capturing their hearts, but over time, often fairly quickly, moving away from a Son-centered orbit. Actually, I not only think people do this all the time, I see people doing this all the time, and it’s heartbreaking. Temporarily captured objects.

Jesus called it out. He spoke about it in the Parable of the Soils when he explained some of its meaning by saying, ”The seed that fell on the rocky soil is likened to those who receive the Word with joy, but they send down no roots, believe for a while, then fall away in time of trouble. The seed that fell among the thorns are those who heard the Word, and as they go on their way are choked with the cares, riches, and pleasures of life, and bring no fruit to maturity.” These are the temporarily captured objects. Then there are those of a different nature, of whom Jesus said, ”Those in the good soil? These are they with an honest and good heart, having heard the Word, hold it tightly, and bring forth fruit with patience.”

Lent is upon us, a season in the church’s year that is meant for introspection, for repentance, for consideration of just why you and I needed an Easter. It’s a good time for self-examination, for soul-searching, for contemplation of whether or not we are ‘all in’ with God. And if not, why not?

God has captured me and has never let me go. It is the same with many I know, and it is my prayer he will capture you as well.

Blowin' in the Wind: Pope Francis and Laudato Si'


(Blowin’ in the Wind is a regular feature on my blog consisting of an assortment of nature writings – hymns, songs, excerpts, prayers, Bible readings, poems or other things – pieces I may not have written but that inspire me or have given me joy. I trust they will do the same for you.)



Many of you have paid attention to the news this week and have read or heard of Pope Francis’ Laudato Si’ Papal Encyclical on the environment. It is a landmark document, long awaited not only by the church but also by all who love God’s creation. Indeed, it is addressed to ‘every living person on this planet;’ How’s that for an audience? I guess a pope can do that.

Here’s something the New Zealand Herald said about it:

While the encyclical will influence the political debate, its most powerful impact could come in its instruction to the world's 1.2 billion Catholics through an "ecological conversion", transforming their own lifestyles to cut waste and end the "throwaway culture…” If taken as seriously as previous encyclicals, such as Humanae Vitae of 1968 which prohibited artificial birth control, it would mean millions of families committing themselves to cooking less food to avoid waste, switching off lights and recycling.
"Nobody is suggesting a return to the Stone Age, but we do need to slow down and look at reality in a different way, to appropriate the positive and sustainable progress which has been made, but also to recover the values and the great goals swept away by our unrestrained delusions of grandeur," the Pope said.

These can only be good developments.

I love the title, Laudato Si’, Latin for “Praise Be to You.” Subtitled “On the Care for Our Common Home,” the main title is taken from the first words of St. Francis’ great 13th Century hymn of praise for creation, Canticle of the Sun, about which I wrote in one of my earlier blogposts nearly two years ago. (I also wrote elsewhere on the hymn based upon St. Francis’ Canticle, All Creatures of Our God and King.) I find it lovely that the Pope chose to honor his namesake in this way.
  
Though the focus for my blog is going to be Pope Francis’ prayer included in the encyclical, here are several of the document’s key points:

- Christians have misinterpreted Scripture and "...must forcefully reject the notion that our being created in God's image and given dominion over the earth justifies absolute domination over other creatures."

- The international community has not acted enough: "Recent World Summits on the environment have not lived up to expectations because, due to lack of political will, they were unable to reach truly meaningful and effective global agreements on the environment." He writes, "The Church does not presume to settle scientific questions or to replace politics. But I am concerned to encourage an honest and open debate so that particular interests or ideologies will not prejudice the common good."

- But individuals must also act. "An integral ecology is also made up of simple daily gestures which break with the logic of violence, exploitation and selfishness."

- Technocratic domination leads to the destruction of nature and the exploitation of people, and "...by itself the market cannot guarantee integral human development and social inclusion."

- Finally, by the way, what is one of the main tasks we have on earth, "...but to be stewards of God's creation?"

The Pope ended the document with a prayer for our Earth that he has asked Christians and others around the world to pray, one that connects faith with nature. (What a concept!) Will you join me in praying this?

High Lord, Who art present in the whole universe
and in the smallest among your creatures,
You who envelop with Your tenderness everything which exists:
You pour into us the strength of Your love,
So that we can take care of life and beauty.
Flood us with peace, so that we may live like brothers
and sisters without harming anyone.
Father of the poor, help us deliver the abandoned and the
forgotten of this earth that mean so much to you.
Restore our life, so that we may protect the world,
not so that we may plunder it,
so that we seed beauty, not pollution and destruction.
Touch the hearts of those that only look for advantages
at the expense of the poor and of the earth.
Teach us to discover the value of everything, to contemplate
with wonder, to recognize our being deeply united with all
creatures on our path toward your infinite light.
Thanks for being with us every day.
Please support us in our fight for justice, love and peace. Amen.

Amen and amen.

From My Nature Journal: It's a Big Place out There...


Some have looked at that same sky and have found themselves discounting the existence of a personal God, what with the vastness of the universe and all; maybe a God could exist who created all of this, but he surely could not trouble himself with the minutiae of me. On the contrary, I have always found David’s confession to be my own: I don’t get it, I don’t know why he’d want to do it (except for love’s sake), but somehow, when it comes down to it, God both knows us and cares for us. Of that I am certain.

…Maybe a God could exist who created
all of this, but he surely could not trouble
himself with the minutiae of me.

It’s this constant source of amazement that has made me a skywatcher ever since my youth. In fact, I had cause to celebrate Psalm 8 again just this week while trying to spot Comet Lovejoy last Sunday night.

What always blows me away, however, is just how big it is out there. So I thought I’d blog this week on some of the celestial objects David himself might have been considering, using some illustrations I ran across years ago for which I do not have a source. I’ll start out with this one, an illustration I call “It’s a Big World out There…”


You can see how much larger Earth is than most of the other planets in our solar system. By the way, if you read this post soon, check out the low western sky about an hour after sunset: the incredibly bright ‘star’ is actually the planet Venus, and the tiny and much dimmer light nearby, a little bit lower and to the right, is Mercury. It’s a rare naked-eye evening conjunction of these two inferior planets, and an exceptionally lovely sight while the sunset’s color still hangs tight against the horizon. (An inferior planet is one in our solar system inside Earth’s orbit around the sun.) Get out and see these soon, though, as the show won’t last long. In fact, in my experience, it is really, really hard to see Mercury at all with the naked-eye, especially when it’s not close to something that helps us pin it. Ready for the next one? I call it, “…Or Not!”


The gaseous superior (outside Earth’s orbit from the sun) planets are enormous compared to Earth. It can almost give you an appreciation for why Pluto was demoted from planet status in 2006. Yet I hear that support is gathering that might allow the little guy to make a comeback soon. Stay tuned. Here’s the next one that I title “But Jupiter’s Not So Hot Either...”


We can hardly fathom the size of our favorite star, by volume equivalent to 1.3 million earths. It makes even Jupiter look more like a marble compared to a beach ball. And heat? The sun’s varies, twenty-seven million degrees Fahrenheit at the core and four million in its coolest spots. But you probably know where I’m going next, though. I call this one “…Because It’s a Big Galaxy Out There.”


Our sun is actually on the tiny size as stars go, and exponentially cooler than the hottest. Sirius is the ‘dog star’ in the constellation Canis Major, The Big Dog (yes, there’s also a Little Dog, but he naturally gets no billing…); Sirius is also the brightest true star in the sky (the planets Jupiter and Venus can appear brighter), and can be found to the lower left of winter’s popular Orion the Hunter. Pollux is one of the twin stars in Gemini, The Twins. Arcturus is in the constellation Bootes the Herdsman, and can always be easily found by following the arc of the handle of the Big Dipper when it is high in the sky (“Arc to Arcturus”). We’ve got one more to go, though: “Actually, It’s all Relative.”


Rigel is the bright, bluish star in the lower right of Orion. This constellation is high overhead in the evenings right now. Aldebaran is the reddish star that constitutes the eye of Taurus the Bull, also directly overhead on early winter evenings. Betelgeuse is the red giant in the upper left of Orion, and huge Antares is the red ‘heart’ of Scorpio the Scorpion, low in the south in the summer evening sky, often confused with ‘The Red Planet’ Mars. Of course, a star’s apparent brightness is always relative to two things: its size and its heat intensity (blue-white stars are hotter than red). But more than this... From our perspective, it is the star’s distance from Earth that plays the biggest part. So obviously, that’s why smaller stars can appear way more luminous to us than larger, hotter ones. Most people cannot see the star closest to Earth, the weak Proxima Centauri, less than five light years away. Sirius, the brightest in the sky, is about nine light years distant. However, it is hundreds of thousands of times smaller than Antares: Antares is likely one of the largest stars in our galaxy, but it is over six hundred light years away, and is a cooler red star compared to the white-hot blue Sirius, so to us it’s only the fifteenth brightest in the night sky.

Even the Bible got that one right, though: “The sun has one kind of splendor, the moon another and the stars another. And star differs from star in splendor (1 Corinthians 15:41).”

By the way, I was successful at spotting Comet Lovejoy last Sunday. It has been cloudy ever since, so another opportunity has not afforded itself. But that night I needed binoculars to do it, and Lovejoy was just a fuzzy ball, not the tailed comet I had hoped to see. Still, it was fun to find, blazing through what would be our constellation Taurus. On the night I observed it, it was about fifty million miles away -- about half as far away as the sun is from us -- and actually heading toward its solar encounter later this month. From there, it is always interesting to see what impact perihelion will have on a comet. (Perihelion is an object’s closest meeting with the sun.) Once the skies clear (tonight?), I’ll try to keep my binocs pointed its direction in the days ahead, all the while praising my Creator:
“Oh, Lord, our Lord, how majestic is thy name in all the earth! (Psalm 8:1, 9)”

And beyond.

P.S. If you’re interested in spotting the comet, here’s a URL sky map that’ll give you the way to find it in the next couple weeks. It’s barreling past and to the right of the Pleiades this weekend.
