Super Blood Wolf Moon for January 2019 - Details, How to Watch, and More
It's a lunar trifecta you can't miss.
Just when I thought things couldn't get any weirder, the news mentions a Super Blood Wolf Moon is coming this month and I instantly question everything. But it's my absolute pleasure to say this lunar trifecta is, in fact, a real thing. Here's everything you need to know about the event so you don't miss it.
What Is A Super Blood Wolf Moon?
Yes, a super blood wolf moon is as crazy as it sounds. Aside from being a rare phenomenon, a super blood wolf moon is three events happening at the same time, a supermoon, a blood moon, and a wolf moon. To start, EarthSky says a supermoon occurs when a new or full moon coincides with the closest point to Earth in its monthly orbit. A blood moon happens when a moon is in total eclipse and appears red because of it's relation the sun. Finally, a wolf moon is simply the first full moon of the year, named after wolves. So what happens when a supermoon, blood moon, and wolf moon take place at the same time? Obviously a super blood wolf moon. Get ready for it.
When Will It Take Place?
The super blood wolf moon of 2019 will take place late on January 20th and/or January 21st, depending on your time zone. According to National Geographic, totality will begin at 11:41 p.m. EST on January 20th and is expected to last for 62 minutes. That said, they note that the entire event will last for three and a half hours.

Galileo’s Newly-Discovered Letter - The Catholic Astronomer
This past September the journal Nature reported on how a long-lost letter of Galileo has been recently found by a science historian at the University of Bergamo, Salvatore Ricciardo. And Nature said Galileo lied. Lied? So what was the letter, and what was he lying about?
Before we get to the lying, let us consider the situation surrounding the letter (some of this will borrow material from an earlier post). The story gets started in about 1608, with the invention of the telescope. Copernicus’s book about his heliocentric theory (saying the Earth circles around the sun and revolves on its own axis), a book entitled De Revolutionibus, had been published in 1543; seven decades had passed with no great interest in that book from outside the world of science. But the telescope and the discoveries Galileo made using it—like the phases of Venus, which demonstrated that Venus must circle the sun, or the moons of Jupiter, which showed that celestial bodies could circle other celestial bodies—had made astronomy into something that was on the minds of people who probably would not have had astronomy on their minds otherwise.

Have Aliens Found Us? An Interview with the Harvard Astronomer Avi Loeb About the Mysterious Interstellar Object ‘Oumuamua | The New Yorker
I recently spoke by phone with Loeb, who was frustrated that scientists saw ‘Oumuamua too late in its journey to photograph the object. “My motivation for writing the paper is to alert the community to pay a lot more attention to the next visitor,” he told me. During our conversation, which has been edited and condensed for clarity, we discussed why Loeb thinks we need to consider the possibility that ‘Oumuamua was sent by aliens, the dangers of unscientific speculation, and what belief in an advanced extraterrestrial civilization has in common with faith in God.

Have Aliens Found Us? An Interview with the Harvard Astronomer Avi Loeb About the Mysterious Interstellar Object ‘Oumuamua | The New Yorker
On October 19, 2017, astronomers at the University of Hawaii spotted a strange object travelling through our solar system, which they later described as “a red and extremely elongated asteroid.

The moon’s craters suggest Earth hasn’t erased lots of past impacts | Science News
History of now - Snowball earth, moon, craters,

The lack of ancient impact craters on Earth (older than 650 mya) was presumed to be due to erosion, plate tectonics.

New evidence from lunar craters suggest otherwise. The bombardment rate between 650mya and 290mya was low and picked (hence few craters on Earth), with an uptick in bombardment around 290 mya (evidence of which does survive on Earth).

The reason for lack of craters before 650 mya? Snowball Earth ~650mya wiped away evidence of earlier bombardments, not plate tectonics and slow erosion from wind and rain.

APOD: 2019 January 17 - Cabin Under the Stars
Explanation: Gocka's, a family nickname for the mountain cabin, and a wooden sled from a generation past stand quietly under the stars. The single exposure image was taken on January 6 from Tanndalen Sweden to evoke a simple visual experience of the dark mountain skies. A pale band of starlight along the Milky Way sweeps through the scene. At the foot of Orion the Hunter, bright star Rigel shines just above the old kicksled's handrail. Capella, alpha star of Auriga the celestial charioteer, is the brightest star at the top of the frame. In fact, the familiar stars of the winter hexagon and the Pleiades star cluster can all be found in this beautiful skyscape from a northern winter night.

Why is the night sky dark?
The mystery of the dark sky is solved by the fact that this history has a beginning—a time before stars and galaxies. Many cosmologists think the universe started out as a very small point, and then started inflating like a balloon in an event called the Big Bang. If you look deep enough, you can see so far back in time that you get close to the Big Bang. “You just run out of stars,” Kinney says. “And you run out of stars, in the grand scheme of things, relatively quickly.”

[1809.05128] Nuclear Processes in Other Universes: Varying the Strength of the Weak Force
Motivated by the possibility that the laws of physics could be different in other regions of space-time, we consider nuclear processes in universes where the weak interaction is either stronger or weaker than observed....

We then consider stellar structure and evolution for the different nuclear compositions resulting from BBN, a wide range of weak force strengths, and the full range of stellar masses for a given universe. We delineate the range of this parameter space that supports working stars, along with a determination of the dominant nuclear reactions over the different regimes....

Although stars in these universes are somewhat different, they have comparable surface temperatures, luminosities, radii, and lifetimes, so that a wide range of such universes remain potentially habitable.

Have Aliens found us? An Interview with the Harvard Astronomer Avi Loeb About the Mysterious Interstellar Object ‘Oumuamua | The New Yorker
Isaac Chotiner talks to Loeb, who thinks that the mysterious object dubbed ‘Oumuamua is an alien artefact:
<p>the evidence in this particular case is that there are six peculiar facts. And one of these facts is that it deviated from an orbit shaped by gravity while not showing any of the telltale signs of cometary outgassing activity. So we don’t see the gas around it, we don’t see the cometary tail. It has an extreme shape that we have never seen before in either asteroids or comets. We know that we couldn’t detect any heat from it and that it’s much more shiny, by a factor of ten, than a typical asteroid or comet. All of these are facts. I am following the facts.

Last year, I wrote a paper about cosmology where there was an unusual result, which showed that perhaps the gas in the universe was much colder than we expected. And so we postulated that maybe dark matter has some property that makes the gas cooler. And nobody cares, nobody is worried about it, no one says it is not science. Everyone says that is mainstream—to consider dark matter, a substance we have never seen. That’s completely fine. It doesn’t bother anyone.

But when you mention the possibility that there could be equipment out there that is coming from another civilization—which, to my mind, is much less speculative, because we have already sent things into space—then that is regarded as unscientific…

…Given the data that we have, I am putting this on the table, and it bothers people to even think about that, just like it bothered the Church in the days of Galileo to even think about the possibility that the Earth moves around the sun. Prejudice is based on experience in the past. The problem is that it prevents you from making discoveries. If you put the probability at zero per cent of an object coming into the solar system, you would never find it!</p>

Weirdly compelling. If it comes back... everyone hide.
