Another gravitational wave observation gave scientists the best evidence yet about one aspect of merging stars. On August 17, 2017, folks with the LIGO/Virgo collaboration observed three clusters of gravitational waves. This time astronomers found an infrared, visible, and X-ray event near where the gravitational wave source. The August gravitational wave observation, GW170817, is the first one where astronomers found electromagnetic waves coming from the same spot. It's a very big deal.

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. More at A Catholic Citizen in America .

Einstein's theories gave scientists good reasons for thinking gravitational waves exist. A century later, instruments detected the elusive radiation. Three American scientists won this year's Nobel Prize in Physics for work that led to the discovery. Observatories in America and Italy have detected three more gravitational wave signals. What they learned wasn't quite what they expected.... More at A Catholic Citizen in America .

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....

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. More at A Catholic Citizen in America .

A Solar eclipse sweeping from coast to coast dominated Monday's news in America. I saw headlines describing the event, weather in different states, how folks had prepared and how they reacted, and some of the science involved. It was nice while it lasted.... More at A Catholic Citizen in America .

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....

We wouldn't expect to find life on 51 Eridani b, even if were the size of Earth and at the right distance from its star. The planet is only a bit over 20,000,000 years old. At that point in our home's long story, the earliest critters wouldn't appear for at least another several million years. We've discovered thousands of new worlds so far, some a bit like Earth, most not; and many not like anything in our Solar System. Scientists are starting to make sense of what's being found, and discovering that we have a very great deal left to learn. More at A Catholic Citizen in America .

There's a huge telescope under construction in Chile: the E-ELT. When compete, astronomers using it plan plan on looking for new worlds, and observing the early universe. We may have spotted a second super-Saturn. We'll know more about that in September.... ...Telescopes have come a long way since Galileo repurposed the " Dutch perspective glass " for astronomical observation. About Galileo, Copernicus, the sun, and the Church: it's true.... More at A Catholic Citizen in America .

We haven't found life on — or in — Enceladus. But we've found organic compounds in the Saturnian moon's salt-water geysers. Scientists detected an atmosphere around Gliese 1132 b, a planet about 39 light-years away. It's Earth-like, in terms of size; but too hot for life as we know it. We'll almost certainly learn a great deal, though, by studying its atmosphere.... ...Abraham, Moses, and Minnesota I take the Bible, Sacred Scripture, very seriously. (Catechism of the Catholic Church, 101 - 133 ) I don't, however, insist on believing only what I find in the Bible. That's just as well, since I live near the center of North America. I'm pretty sure that Abraham, Moses, Joshua, Saint Peter, and the rest, didn't know that the land I live on exists. But I'm quite sure that the State of Minnesota is real: even if it's not "Biblical."... More at A Catholic Citizen in America .

These are exciting, or disquieting, times. Which it is depends partly on how much a person likes living in a world where scientific knowledge is rapidly changing. I like it, a lot.... ...Since this is a "religious" blog, I'll be discussing — briefly, for me — how my faith relates to experiments using CERN's Large Hadron Collider and science in general....

TRAPPIST-1's planets may support life: or not. We don't know. Not yet. We're pretty sure that all seven are rocky worlds, like the Solar System's inner planets. Three are in the star's habitable zone. The inner two definitely do not have one sort of atmosphere that would make life as we know it impossible. Even if we don't find life there, we'll learn a great deal while looking. More at A Catholic Citizen in America .

Scientists found PCBs and PBDEs in deep-sea critters, armyworms are on the march in Africa, and Mexico City's air isn't as clean as we'd hoped. Rational concern seems reasonable.... ...Last week I talked about blaming our tools for our mistakes. ( February 10, 2017 ) This week I'll revisit Lovecraft's "placid island of ignorance,"sort of....

Statues 1 of Caspar , Melchior , and Balthazar started near the clock in our living room. I took those pictures of them on Wednesday. Their trip to the nativity scene ended today, Epiphany Sunday. We read about "magi from the east" in today's Gospel: Matthew 2:1 through 12 : " 1 When Jesus was born in Bethlehem of Judea, in the days of King Herod, 2 behold, magi from the east arrived in Jerusalem, "saying, 'Where is the newborn king of the Jews? We saw his star 3 at its rising and have come to do him homage.'" ( Matthew 2:1 - 2 ) "Magi" is how μάγοι, mágoi, looks in my native language. That's the Greek version of an Old Persian word that would sound something like "magus" if I tried pronouncing it. More at A Catholic Citizen in America .

I'd love to be talking about unambiguously artificial signals picked up by the Allen Telescope Array , or reports of a ship from beyond the Solar System settling into orbit around our moon. But that hasn't happened, and probably won't. Not in my lifetime. Instead, I'll talk about why I don't "believe in" extraterrestrial life; and do not assume that we are alone in the universe. That puts me in the third of folks who aren't sure, and I'll get back to that. My 'Friday' posts are usually about more-or-less-current 'science news.' That won't happen this week. I've read a few interesting articles, and will be talking about them — after the Christmas-New Year's gymkhana is over. This week I'm using material that didn't quite fit into an earlier post. I'll also talk about the Great Moon Hoax, Nicola Tesla and Martians; and what I think about life in the universe. More at A Catholic Citizen in America .

Pip's Christmas doesn't have much to do with Christmas, or Advent, but I figured this post should have something that looks 'seasonal.' "...Blessed is the One Who Takes No Offense at Me" We'll be hearing Matthew 11:2 - 11 this morning. The readings still aren't particularly 'Christmassy.' " 2 When John heard in prison 3 of the works of the Messiah, he sent his disciples to him " 4 with this question, 'Are you the one who is to come, or should we look for another?' "Jesus said to them in reply, 'Go and tell John what you hear and see: " 5 the blind regain their sight, the lame walk, lepers are cleansed, the deaf hear, the dead are raised, and the poor have the good news proclaimed to them. "And blessed is the one who takes no offense at me.' " ( Matthew 11:4 - 6 ) Our Lord balanced that rebuke with a reminder of the Baptist's great function in Matthew 11:7 - 15 , and a complai

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....

KIC 8462852, Tabby's Star, has been in the news recently. Scientists are pretty sure that something very large orbits the star, but haven't worked out what it is. A few scientists, looking at the data, say that it's probably a really odd natural phenomenon: but that it might something built by folks who aren't human. SETI, the Search for Extraterrestrial Intelligence, is still a science in search of a subject. But quite a few scientists are taking it seriously, which is why Berkeley SETI Research Center added few stars to the Automated Planet Finder's observing queue.... ...What I say about SETI and science in general may take some explaining, if you're new to this blog. Basically, I think God is large and in charge; and that part of my job is appreciating God's work — not telling the Almighty how it should have been made...." More at A Catholic Citizen in America .

Scientists spotted 2016 UR36 days before it passed by Earth. "Killer asteroids" headlines notwithstanding, we knew it would miss our planet by a comfortable margin. Sooner or later, though, something big will hit Earth: again. We still can't prevent that, not yet. More at A Catholic Citizen in America .

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.
