Way back in the late 1980s when the rocks were still cooling, I wrote a pair of novels, From a Changeling Star and Down the Stream of Stars, that proposed an interstellar highway (sort of a modified wormhole) created by the joining of two black holes with a long strand of cosmic hyperstring. That same starstream features prominently in my new work, The Reefs of Time / Crucible of Time.
Now, I read here that real scientists have proposed that one could create a real wormhole, using—are you ready?—two black holes and a couple of strands of cosmic string. Seriously, is that cool or what? God, I love science!
Mars Reconnaissance Observer (MRO) took pictures from orbit of the Phoenix Mars lander, roughly ten years apart. If this animated gif from NASA works correctly, you’ll see a blink comparison of the site ten years ago, and now. The evidence could not be more striking: Little Green Men (LGMs) have been systematically covering our lander with sand! They work slowly but steadily; they’ve even hidden the parachute (bottom). My theory is they’re part of the Flat Mars Society and are covering up evidence of life from off world. How devious.
This, combined with the famous hex-wrench socket on top of Saturn (see in motion here), offer clear proof of aliens meddling in and around our solar system. I suspect they live inside Saturn and go in and out through the hex hatch, but this has not yet been shown. Sciency research continues.
The Cassini spacecraft is about to end its role in one of the most incredible scientific journeys in history. Launched almost twenty years ago on a billion-mile trip to Saturn, Cassini has been sending back astounding images and data ever since. An international collaboration of U.S. and European space agencies, Cassini has probably delivered more surprises to researchers on Earth than any probe before or after—ranging from pictures of the mist-shrouded surface of Titan with its methane lakes and rivers, to the water geysers and hidden ocean of Enceladus, to the stunning beauty and complexity of the rings, to the crazy giant hexagon* on the north pole of Saturn itself.
NASA has produced a breathtaking video summary of Cassini’s journey, which I would embed here if I could find the embed code. But click here, and watch it in full screen. It’ll be the best five minutes you spent today.
Cassini has been a workhorse of stellar quality. But it’s finally running out of fuel—years after the originally planned end date of its mission—and to keep it from accidentally colliding with one of the potentially life-hosting moons, it’s going out in a blaze of glory, burning up tomorrow morning in Saturn’s upper atmosphere. It makes me sad. I wish it could have been kept in a parking orbit somewhere safe, so that some future exploration crew could have docked with it, put placards on it, and turned it into the Saturn branch of the Smithsonian, to be kept in perpetuity. But caution ruled, and rightly so, I guess. We’re looking eagerly for extraterrestrial life, and it wouldn’t do for the field to be littered with bits of Earth life. Plus, she’ll be doing science all the way in as she augers into Saturn, where she’ll melt and burn and vaporize at the end. What a way to go.
I feel kind of weepy, imagining that. But you can watch it live right here, Friday morning at 7-8:30 a.m. EDT.
I was just reading in Astronomy Magazine that astronomers have predicted that a binary pair of stars will merge into one in 2022, and set off an explosion called a red nova, similar to this image of V838 Monocerotis, from the Hubble space telescope. It’ll be as bright as the North Star, and last for up to six months. That’s a pretty striking prediction, and not the sort of prediction astronomers usually make. (More here.) But here’s the thing…
I was most of the way through the article when I went, Wait—who? I scrolled back up to read again, who’s being quoted here. I wasn’t seeing things—it’s Lawrence Molnar of Calvin College in Michigan. Way to go, Larry! Larry Molnar and his wife Cindy are friends from way back, having lived right above us for several years right after Allysen and I got married. We went to the same church; we exchanged babysitting. He was my first consultant on the question of how one could theoretically set off a supernova (From a Changeling Star), and he introduced me to other consultants at Center for Astrophysics at Harvard. We also made a snow dog together (modeled on Sam, our first border collie mix), back in the 1980s.
This is cool. I’m going to be watching, Larry, to see if it happens on time.
Curly and Moe were not mentioned as participants in the study.*
*Sorry. That’s the only part of this post that’s an April Fools joke. The rest is real.
Huge news from the world of astronomy! A planet has been discovered circling the closest star to ours, just 4.25 light-years away! And it may be in the Goldilocks zone—neither too close to its star nor too far away to have liquid water. Proxima is a red dwarf, much smaller than our sun, and Proxima b (the planet) is orbiting much closer to its star than Earth, with an orbit around its sun every 11.2 days. The net effect of this is that, depending on what kind of atmosphere it has, the surface temperature could be moderate enough for water to exist in liquid form: ideal for our kind of life. This is big news, even bigger than the apparent discovery a few years ago of a planet circling Alpha Centauri (part of the same star group, but a little further away). Read the details on Phil Plait’s Bad Astronomy blog. And here’s a video from the European Southern Observatory:
Regarding that previous discovery around Alpha Centauri, it was (according to Phil Plait’s article) later found to be an error. But he thinks the evidence for this one is a lot more solid. So here’s hoping, and let’s start tuning up that stardrive!
What better way to crown the Fourth of July, a celebration of the birth of the U.S.A., than to plunk a billion-dollar spacecraft—Juno, the fastest-moving probe ever launched by humanity—into a perfect orbit around Jupiter? This isn’t just any orbit. NASA had to thread Juno into a precise path taking the craft between the planet’s upper atmosphere and its hellish radiation belt. Too close to that belt, and the instruments would have been instant toast. Fortunately, NASA eats challenges like that for lunch. Juno will be flying a highly elliptical path over the huge planet’s poles, zooming repeatedly to within a few thousand miles of the atmosphere and then whipping way out for a long-distance view.
Like so many space stories, there’s a lot in this that echoes my current work in progress. Readers of The Chaos Chronicles might remember that Li-Jared comes from Karellia, a planet with a fiery radiation belt surrounding it. In The Reefs of Time, Li-Jared (and we) get a chance to visit that world, which features things even weirder than the “beautiful, perilous sky” that its inhabitants know so well.
Take a moment to enjoy this view of Jupiter’s moons circling the great planet, shot by Juno on its flight inbound.
Astronaut Scott Kelly is coming home from the International Space Station after 340 days in orbit. Click here at the Boston Globe for a gallery of some amazing images he shared during his time at the edge of the great Up-and-Out.*
*If the “Up-and-Out” is unfamiliar to you, you may not have had the pleasure of reading any of the stories of the late Cordwainer Smith. Here’s one of my favorites, The Game of Rat and Dragon. It starts this way:
