Science, Faith, and Me



This universe is bigger and older than some folks thought, a few centuries back.

I don't mind, at all. Besides, it's hardly new information. We've known that we live in a big world for a long time.
"4 Indeed, before you the whole universe is as a grain from a balance, or a drop of morning dew come down upon the earth." (Wisdom 11:22)
If that bit from Wisdom doesn't sound familiar, I'm not surprised. It's not in the Bibles many Americans have. The one I read and study frequently is the unexpurgated version....

Finding New Worlds

We could detect oxygen in Proxima Centauri b's atmosphere. It's a biosignature, but not proof of life.

Some extrasolar planets are like Earth, almost. Many are unlike anything in the Solar System.

I'll be looking at recently-discovered worlds; some almost familiar, others wonderfully unexpected. Also an informal 'top 10 best exoplanets' list.

Planet 9, Maybe; Nibiru, No

The world didn't end last Saturday. That's nothing new, and neither is another fizzled End Times prediction.

I'll be talking about how a current End Times prediction affected someone whose name is the same as the wannabe prophet's; but is an entertainer, not a doomsayer.

I'll also take a look at the continuing, and serious, search for Planet 9; predictions involving close encounters of the cometary kind; and what we're learning about the outer Solar System....

Cassini-Huygens Mission

The Cassini-Huygens mission ends this week, after 13 years in orbit around Saturn. Scientists found answers to some questions they had, and uncovered new questions.

I think they'll be studying Cassini's and Huygens' data for years. Decades.

I'll take a quick look at what we've learned, and why scientists want follow-up missions to the Saturn system.

The Enceladan subsurface ocean wasn't a complete surprise.

Expectations



Danae's odd view of Papal infallibility isn't accurate. (July 30, 2017)

But I'm not upset by Non Sequitur's 'Church of Danae,' particularly since I see the funny side of the cultural quirks Wiley Miller highlights.

I do, however, occasionally use Danae's distinctive theology and Eddie's "Biblical Prophecies" as a contrast to my faith.

I'm a Christian, and a Catholic.

I have well-defined views on social and legal issues: but I am not conservative or liberal. I'm Catholic.

That means acting as if Jesus, love, and people matter....

Repeatable Results That Aren’t

I'll be talking about scientific research that may not be "fake:" but isn't reliable, either. The good news is that many scientists want to fix the problem.

I'll also take a look at truth, beauty, Copernicus, and how a science editor sees faith and science.

Mars: Leaky Red Planet

What we're learning about Mars, and a new type of really small spacecraft, reminded me of earth, air and kilts.

Also pharaohs, Thomas Paine, and Lord Kelvin. By then I was running out of time to write something more tightly-organized.

I figured you might be interested in some of what I have written. On on the other hand, maybe not. So I added links to my ramblings before and after what I said more-or-less about the science news, and figure you can decide what's interesting and what's not.

Tides and Our Moon’s Origin

Scientists have been wondering how our moon formed, and why its orbit isn't over Earth's equator.

It looks like our moon formed after something about the size of Mars hit Earth, roughly 4,500,000,000 years back.

But the giant-impact hypothesis didn't explain why our moon orbits Earth only five degrees away from Earth's orbital plane. The math had said that our moon would be orbiting pretty much over Earth's equator....

...God is Large and In Charge


I occasionally wonder if I should keep explaining why reality doesn't offend me, and why facts don’t threaten my faith....

Europa, Mars, and Someday the Stars

Scientists think they've detected more plumes of water, shooting up from near Europa's south pole. It's early days, but we may have found a comparatively easy way to collect samples from the Jovian moon's subsurface ocean.

Stephen Hawking says humanity needs to keep exploring space. I agree, although not quite for the reasons he gave.

SpaceX tested an engine they plan to use on their Mars transport, and Gaia's data seems to have raised as many questions as it answers.

Philae, Jupiter, and Life

Scientists spotted Philae, the European Space Agency's spacecraft that crash-landed on 67P/Churyumov-Gerasimenko in 2014: which will help them make sense of data sent back while the probe still functioned.

Other scientists think they’ve worked out where carbon near Earth's surface came from, and the Juno orbiter has been sending pictures of the giant planet.

Studying Thousands of New Worlds

Scientists studied the atmospheres of two exoplanets, planets orbiting another star, earlier this year. Both planets are roughly Earth-sized, with atmospheres a bit like the Solar System's terrestrial planets.

Juno arrived at Jupiter last month, and will start its science mission in October.

Finally, scientists found more than a thousand new planets; including more than a hundred Earth-sized ones.

Barsoom Development Ltd.

The Curiosity Mars Rover sent a 'postcard' from Mars, a 360-degree view of dunes and a mountain in Gale Crater....

...As usual, I'll ramble on about science, technology, and being human before getting to the interesting stuff: assuming that you think a robotic selfie from Mars is interesting.

Not-entirely-as-usual, I wasn't finished rambling when I started the 'postcard' stuff, so this post has an afterword. I've done that before....

On Mars by 2040?

Robots have orbited Mars, landed there, driven around, taken pictures, and studied Martian rocks.

But humanity's exploration of Mars has been by proxy: Nobody's gotten farther from Earth than Lunar orbit.

That could change before 2040. NASA has worked out a step-by-step plan for getting humans back into deep space: provided that Congress doesn't change its mind.

Even if that happens, my guess is that it wouldn't be long before someone else decides that people should act like humans....

SpaceX, Mars, and Someday the Stars

First of all: Merry Christmas! I'll have something more seasonally-appropriate ready by Sunday. That's the plan, at least.

Today I'll be talking about spaceships, practical and otherwise: and why NASA cancelled InSight's March 2016 launch....

...Instead of trying to analyze the reasons, I'll just get started with the December 1938 issue of Amazing Stories, Columbus, Robert Goddard, the Hanseatic League, and why airlines don't use disposable airplanes — not necessarily in that order....

Ceres, Pluto: There’s More to Learn

That's part of a picture from New Horizons: a sample from the highest-resolution images the spacecraft has started sending back.

We're pretty sure that the mountains are frozen water, and the flat parts softer "ice:" probably including frozen nitrogen.

The first journal paper using New Horizons' flyby data was published in October: but there's a great deal left to study, and even more still stored on New Horizons. (November 13, 2015)

Other scientists think they've found evidence that those bright spots in Occator Crater are frozen water, exposed when something hit Ceres. If they're right, the impact(s) happened recently. I'll get back to that.

Pluto’s Cup-Capped Mountains

Before the New Horizons mission, we knew Pluto was very cold, had little or no atmosphere, and that was about it. (October 30, 2015; July 10, 2015)

Now scientists think they've spotted 'ice volcanoes' on Pluto that look a lot like shield volcanoes on Earth and Mars....

...we're rational creatures, created in the image of God, and "little less than a god." Studying this universe, and using that knowledge is part of our job. So is using our power responsibly....

Kerberos, Mars: Answers Raise New Questions

Images sent back from New Horizons gave scientists their first opportunity to see how big Kerberos is. It's much smaller than they expected, which raises new questions.

Meanwhile, the Mars Reconnaissance Orbiter's instruments provided evidence that there's running water on Mars: every summer, on some crater slopes. It's not the Mars of Burroughs' Barsoom tales: but I think the planet is getting more interesting, the more we learn about it.

New Horizons and Ceres

New Horizons will pass by another Kuiper Belt object in January, 2019, if NASA's proposal gets the go-ahead.

Closer to home, Dawn is still sending back data from Ceres: including an image of a very odd-looking mountain....

Pluto, Earth 2.0, and Life in the Universe


Pluto may have nitrogen glaciers, and the planet's air pressure is much lower than scientists expected.

Kepler 452b, "Earth 2.0," isn't the first roughly Earth-size planet found in a star's habitable zone: but the star, Kepler 452, is remarkably similar to our sun.

Another planet, HIP 11915b, is the first we've found that's around Jupiter's size: and orbiting its star at about the same distance as Jupiter. This is the first other planetary system that 'looks like' our Solar system.

Scientists still haven't found life elsewhere in the universe: but the odds seem to be getting better that we will, eventually....

...A 'science threatens faith' op-ed got my attention this week, so I wrote about beliefs, reasonable and otherwise, before getting around to the interesting stuff. Feel free to skip ahead to Pluto's Probable Glaciers, take a walk, or whatever suits your fancy....

Pluto's Unexpected Terrain; SETI, Radio, and Drums

Pluto's still in the news, as New Horizons starts sending data from its July 14 flyby. That will take more than a year, but there have already been surprises: including "not easy to explain terrain" near Pluto's equator.

Meanwhile, the DSCOVR Solar weather monitor sent back a snapshot of Earth; and Professor Stephen Hawking is supporting a new search for intelligent life in the universe.

I think the Royal Society in London's Breakthrough Initiatives group will collect interesting facts while listening for extraterrestrial radio broadcasts. But I also think that our neighbors could easily have been using wireless telegraphy when Oldowan tools were our high tech.

Antarctic 'Hot' Spots

Some scientists say there'll be more carbon dioxide in Earth's atmosphere this year. They may be right. I think the information...
