Oh, sure, the Democratic leadership says it takes climate change seriously, but that same leadership has sidelined the Green New Deal and gutted the climate committee, replacing it with a lame-duck committee led and staffed by beneficiaries of big energy sector dollars. Read the rest

r/megalophobia is a my new favorite subreddit, specializing in things that are very big and therefore very, very scary. Postings range from Lovecraftian monsters looming in the mist to zoom-out animations impressing upon the viewer the insignificance of Planet Earth and all human concerns. Currently popular are disturbing photoshops of large comets looming over the major cities they are about to destroy.

First discovered a year ago, Oumuamua is the strange cigar-shaped object of interstellar origin that flew through our solar system at 196,000 mph. Since it was first spotted, scientists haven't decisively determined whether it's a mildly active comet or something else. Now, astronomers Shmuel Bialy and Abraham Loeb of the Harvard Smithsonian Center for Astrophysics have released a scientific paper asking if Oumuamua could be a "lightsail of artificial origin," part of a space probe developed by an advanced extraterrestrial civilization. Of course this is not a statement of fact but rather a question, albeit a very very interesting one. From CNN:

"'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.

The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018.

"Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.

Fireball is Werner Herzog's forthcoming documentary "about meteorites and comets and their influence on mythology and religion," according to Variety. He's once again collaborating with British geoscientist Clive Oppenheimer, his partner on the volcano documentary Into the Inferno. From Variety:

The producers of “Into the Inferno,” Andre Singer and Lucki Stipetic, are both on board “Fireball.” Herzog and Oppenheimer will co-direct. They will once more go globe-trotting, this time to visit sites that yield insight into comets and meteorites and help them understand what they can tell us about the origins of life on Earth.

In the late 19th century, artist/astronomer Étienne Léopold Trouvelot (1827-1895) painted thousands of stunning works illustrating the beauty and science of the known planets, comets, and celestial phenomena. The Huntington Library near Los Angeles holds 15 of Trouvelot's chromolithographs that were published in 1882 in two portfolios, the Trouvelot Astronomical Drawings:

Initially, the Astronomical Drawings portfolios were sold to astronomy libraries and observatories as reference tools, but as early 20th-century advances in photographic technology allowed for more accurate and detailed depictions of the stars, planets, and phenomena, Trouvelot’s prints were discarded or sold to collectors.

Now that's a pretty comet. ESA:

Enjoy this compilation of with the last images taken by Rosetta’s high resolution OSIRIS camera during the mission’s final hours at Comet 67P/Churyumov-Gerasimenko. As it moved closer towards the surface it scanned across an ancient pit and sent back images showing what would become its final resting place.

The pretty far reaching study we blogged last week, about Octopi coming from outer space, is really most likely, probably, near certainly not true.

Via Space.com

For evidence of the panspermia hypothesis, the authors wrote in their new paper, skeptics need only look to the octopus.

Octopuses have complex nervous systems, camera-like eyes and a capacity for camouflage that evolved suddenly and without precedent in their family tree, according to the study authors. The genes for these adaptations, the authors wrote, do not seem to have come from octopus ancestors, but "it is plausible then to suggest [these traits] seem to be borrowed from a far distant 'future' in terms of terrestrial evolution, or more realistically from the cosmos at large."

In one theory laid out in the paper, the authors posit that fertilized octopus eggs crashed into the sea aboard an icy comet at the onset of the Cambrian explosion. Another explanation, they propose, could be that an extraterrestrial virus infected a population of early squid, causing them to evolve rapidly into octopuses as we know them today.

Other researchers were not quick to embrace this theory. "There's no question, early biology is fascinating — but I think this, if anything, is counterproductive," Ken Stedman, a virologist and professor of biology at Portland State University, told Live Science. "Many of the claims in this paper are beyond speculative, and not even really looking at the literature."

For example, Stedman said, the octopus genome was mapped in 2015. While it indeed contained many surprises, one relevant finding was that octopus nervous system genes split from the squid's only around 135 million years ago — long after the Cambrian explosion.

Landru79 created this spectacular GIF from images captured in 2016 on the surface of Comet 67P/Churyumov–Gerasimenko by the European Space Agency lander Philae deployed by the Rosetta probe. The video is significantly sped up, compressing 25 minutes into a few seconds of intense action. But what exactly are we looking at in this pandemonium? From New Scientist:

Much of this apparent “snow” wouldn’t actually be visible if you were standing on 67P’s surface. It is made of cosmic rays – charged subatomic particles that flit across the universe. As they hit the camera’s sensors, they register as streaks of light.

Some of bright specks are actually snow – dust and ice particles floating above the comet’s surface. And many of them are stars behind the rocky cliffside on 67P’s surface.

Some new calculations suggest that a small red-dwarf star -- accompanied by a smaller brown dwarf -- flew so close to our solar system 70,000 years ago that it passed through the Oort Cloud.

This blows my mind.

That is dementedly close to Earth! I mean, viewed one way, the Oort Cloud -- the ring of icy material that surrounds the solar system, and which is the likely source of the comets we see on Earth -- is very far away: 0.8 light-years. But considered in terms of interstellar enormitude, that's basically our backyard. Consider that the original Voyager space probe will probably enter the Oort Cloud in 300 years.

Or to put it another way, an object made by humans will, in just a few generations, be chilling in the same region that not too long ago saw another damn star swing by. And yeah, 70,000 years is, in cosmological time, not that long ago at all.

In fact, our ancestors may have seen the star as it swung through the neighborhood. As a press release by the scientists notes:

Currently, Scholz’s star is a small, dim red dwarf in the constellation of Monoceros, about 20 light years away. However, at the closest point in its flyby of the solar system, Scholz’s star would have been a 10th magnitude star – about 50 times fainter than can normally be seen with the naked eye at night. It is magnetically active, however, which can cause stars to “flare” and briefly become thousands of times brighter.

Courtesy the International Comet Quarterly, here's a list of meteorite strikes that focuses on situations where the meteorite hit something -- ranging from houses to cars to mailboxes and even a dog. There are a surprising number of tragic deaths; I can't imagine what the odds are of being maimed or killed by a meteorite, but it's got to be awfully high.

Political scientist and sf fan Henry Farrell (previously) argues persuasively that the dystopian elements of our everyday life are best viewed through the lens of Philip K Dick (whose books repeatedly depicted a world of constructed realities, whose true nature was obscured by totalitarians, conspiracies, and broken computers) and not Orwell or Huxley, whose computers and systems worked altogether too well to be good parallels for today's janky dystopia.

The climate in Game of Thrones is incredibly weird, not least because of the strange timing of the oddly-long seasons. A group of climate scientists from the Universities of Bristol, Cardiff, and Southampton decided to figure out what's going on by making a climate model of the world -- based on the weather data they could scrounge from George R. R. Martin's novels. They wrote it up as a mock academic paper authored by the GoT character "Samwell Tarly".

Their/his key finding? The only way to create a model that behaves like the world described in the books is to assume the planet in Game of Thrones "tumbles" as it orbits its sun:

One way that seasons can be made to last longer is to allow this tilt of the spinning axis to change throughout the year, so that the Earth ‘tumbles’ on its spin axis, a bit like a spinning top. If the Earth ‘tumbles’ exactly once in a single year, then the spin axis always points towards (or away) from the Sun, and the winter (or summer) is then permanent (Figure 3(b)).
