I love the “illustrative diagram” note for people who might complain this is not scientifically accurate due to scale.
…if you are lucky enough to live Western Europe, parts of northwestern Africa, and some of the Americans…
As for why the Moon appears red…
“You’ll actually be seeing every sunrise and every sunset occurring around the Earth at once. All of that light will be projected on to the Moon.” (Dr Gregory Brown, Royal Observatory
And if you happened to be standing on the Moon at the time, you’d see a blood ring encircling the Earth in front of you (ah, assuming you were not on the other side of the Moon).
Come on. Somebody has got to figure out how to get a picture of that.
“Perhaps most intriguing among the documents are the several dozen Defense Intelligence Reference Documents (DIRDs), which discuss the viability of various “advanced technolog[ies].” This collection includes reports on “traversable wormholes, stargates, and negative energy,” “high-frequency gravitational wave communications,” “warp drive, dark energy, and the manipulation of extra dimensions,” and many other topics that will sound familiar to fans of science fiction.”
(Note: You won’t be able to see the planets actually looking like these photoshopped images…unless you happen to have a really powerful telescope in your backyard.)
Not sure why I first got this info from a site based in New Jersey. The info about what time of day and in what part of the sky is only relevant to people living in the NJ_NYC area.
Still, it’s an interesting phenomenon that occurs once every few years…
2005. 2016. 2020. And 2022. Not exactly a regular pattern, it seems.
And, no, there is no “spiritual significance” to a planetary alignment. It’s an illusion, an imaginary lining up of the solar system that doesn’t affect you personally. Sorry.
But it’s still fun to watch. Er, if you enjoy getting up before dawn (I don’t).
According to nj.com, “The planetary parade of sorts will occur when Jupiter, Venus, Mars and Saturn all appear to be lined up in a row above the horizon during the pre-dawn hours — starting Saturday morning, April 23. The alignment will also be visible during the next few mornings, and April’s crescent moon will soon join the parade, according to experts from LiveScience and AccuWeather.”
Yeah, lots of web sites are covering this. At least the one I linked above doesn’t have automated videos, flashing ad gifs, and other random pop-ups that drain your smartphone battery.
In short, the algae will use sunlight to transform CO2 into sugars that are then enhanced by bio-engineered E.coli into 2,3-butanediol. Interestingly, 2,3-BDO is not entirely conceptual as it currently exists and is mainly used to produce rubber components. It has just never been thought of as fuel before.
Psyche is an asteroid that was probably once the heart of a planet in the early system, one that didn’t survive the violent process of planet formation.
Yep — that “worth more than the global economy” rock in space.
But we’ll have to wait a few years to find out if it’s “less metal and more hard rock” — the Psyche Mission rockets off in August 2022 and the probe won’t arrive for four more years.
“We give off waste heat (from industry and homes and so on) and artificial light at night, but perhaps most significantly, we produce chemicals that fill our atmosphere with compounds that wouldn’t otherwise be present. These artificial atmospheric constituents just might be the thing that gives us away to a distant alien species scanning the galaxy with their own powerful telescope.”
SuperCam showed that the coatings are enriched in hydrogen and sometimes magnesium. In addition, images from Mastcam-Z suggest that they also contain iron oxides. Both the hydrogen and iron oxides point to past water being involved in the formation of the coatings. That shouldn’t be too surprising, perhaps, since this area in Jezero Crater used to be a lake a few billion years ago.
The rocks resemble so-called desert varnish, which protect microbes from the sun’s radiation. It’d be interesting to find out whether cyanobacteria that once existed on Mars did this…but the four billion year old question is, how did those bacteria get there in the first place?
They slice. They dice. They perform complicated microsurgery without the aid of doctors…
US researchers say a robot has successfully performed keyhole surgery on pigs all on its own – without the guiding hand of a human. Furthermore, they add, the robot surgeon produced “significantly better” results than humans.
New analysis of one of Saturn’s moons suggests that it may harbor a liquid ocean. No, not the usual suspects – the new culprit is Mimas, the little moon with a big crater, which gives it more than a passing resemblance to the ‘Death Star’ from Star Wars.
