Are we alone in the universe? It's a question whose answer—whether it’s yes or no—would philosophically and scientifically rock our world to the core.
To find out, scientists have long been turning powerful radio telescopes to the cosmos. The theory is that, like us, other intelligent species are perhaps broadcasting radio signals with the distinctly "unnatural" signature of a technological civilization.
But despite decades of intent listening, we’ve yet to pick anything up. Even in a recent survey of 10 million stars by the Murchison Widefield Array radio telescope in Western Australia—one of the most extensive to date—scientists found nothing of note.

The Harvest Moon of 2020 rises tonight! But why is it in October? | Space
If it seems a bit late to you, you're not alone. Each year, the full moon that occurs nearest to the autumnal equino x and is thus christened the Harvest Moon. Usually this title goes to the September full moon . There are other versions of this rule that classify the Harvest Moon as the full moon that comes either at or just after the equinox, which, more-often-than-not, would also put it in October.
While the average occurrence of an October Harvest Moon is once every three years, sometimes as much as eight years can pass between such cases. In fact, the next time we will see a Harvest Moon in October will be in 2028.
Texas company aims to 3D-print buildings on the moon with 'Project Olympus' | Space
Austin-based startup ICON, known for 3D-printing houses here on Earth, just launched Project Olympus, an ambitious effort to develop a space-based construction system. The program will eventually help humanity get a foothold on the moon and Mars, if all goes according to plan.
"From the very founding of ICON, we've been thinking about off-world construction. It's a surprisingly natural progression if you are asking about the ways additive construction and 3D printing can create a better future for humanity," ICON co-founder and CEO Jason Ballard said in a company statement .
Your Stargazing Guide To October: Halley's Comet Meteors, Dazzling Mars And Halloween's 'Blue
October is always a great month to go stargazing, and in 2020 it's got some truly unmissable sights.
In the northern hemisphere October means longer nights, and when the clocks change it makes stargazing a possible in the early evening.
Insert a couple of meteor showers—one that's visible right after sunset and another caused by none other than Halley's Comet—and you've got a busy celestial month that deserves an intriguing finale.

Was the moon magnetized by impact plasmas? | Science Advances
The crusts of the Moon, Mercury, and many meteorite parent bodies are magnetized. Although the magnetizing field is commonly attributed to that of an ancient core dynamo, a longstanding hypothesized alternative is amplification of the interplanetary magnetic field and induced crustal field by plasmas generated by meteoroid impacts.
The Moon presently lacks a core dynamo magnetic field. However, it has been known since the Apollo era that the lunar crust contains remanent magnetization, with localized surface fields reaching up to hundreds of nanoteslas or higher and spanning up to hundreds of kilometers ( 1 ). Magnetic studies of Apollo samples and the lunar crust indicate that the magnetizing field likely reached tens of microteslas before 3.56 billion years (Ga) ago ( 1 , 2 ).
Watch BMX bike legend Terry Adams dance with the Harvest Moon (video) | Space
Here's the Harvest Moon as you've probably never seen it before — beneath the handlebars of a BMX icon.
Terry Adams, one of the best BMX trick riders in the world, danced on two wheels in the orange light of a rising Harvest Moon Thursday night (Oct. 1), as a new video shows.

Adams did his thing in northwest Arkansas, rolling on a platform built into a scenic, bouldery shoulder of the Ozark Mountains.
"This project proves you can take flatland BMX anywhere in the world," Adams said in a statement. "I've always dreamed about riding next to a cliff or edge of a mountain, so doing something so special feels like a dream come true."
'Giant impact' theory of moon's formation gets another boost | Space
Scientists have found fresh evidence in lunar rocks showing that the moon was likely formed after a Mars-sized planet crashed into the proto-Earth more than 4 billion years ago.
A NASA-led team examined moon rocks brought back to Earth by Apollo astronauts more than 50 years ago. Investigating the samples with advanced tools not available to researchers in the 1960s and 1970s, the team found further evidence of the "giant impact theory" by focusing on the amount and type of chlorine in the rocks, a new study reports.
I see the moon... | Outdoors | grandrapidsmn.com
Some people think about "carrying moonbeams home in a jar," duck hunters are fine with them over decoys.
If you have ever hunkered in a ducking "hide" (old school for duck blind) in the deep shadows of night's swan song under the light of a silvery full moon listening to a light breeze ruffle cattails while a far-off mallard quacks marsh revelry, you know there is much more to this thing we of the camo and hip-boot ilk call duck hunting.
Oddly enough, those of us who have without hesitation frittered away many mornings duck hunting with reckless abandon don't think twice about how there is very little talking because waterfowl partners pretty much know exactly what to do and when to do it. We also understand how every predawn is as awesome as any good son or daughter of the North could ask for.
