kenkenken, w NASA's solar sail successfully spreads its wings in space
@kenkenken@fedia.io avatar

Oh no, Ramiel is already here!

flicker,

Poor Shinji.

PunnyName, w Highest-resolution black hole images ever taken usher in a new era

Yeah, science!

moon, w [Scott Manley] How Failed Gyros Are Making Hubble's Life Harder
lvxferre,
@lvxferre@mander.xyz avatar

Yeah. I’m half-drunk but the first thing that I thought was, “I could use some gyros. Preferably with a buttload of tzatziki”. (The video is about gyroscopes though. Also cool. But not edible.)

RamblingPanda,

Not half drunk but in the same boat. And it took me a while to get the headline.

Diplomjodler, w [Eric Berger] Seeing this eclipse is probably the highest-reward, lowest-effort thing one can do in life

Except of course, when it’s cloudy. The only eclipse that ever happened where I lived in my lifetime was a total disappointment because you couldn’t see anything.

troyunrau, w Regulation needed to protect space tourists from cosmic rays
@troyunrau@lemmy.ca avatar

Easy. If you can afford to be a space tourist, you can afford to put $5M in escrow for your future medical expenses.

Let’s take risks people!

troyunrau, w Want to be a NASA astronaut? Applications are open

A half dozen years ago, or thereabouts, I entered the Canadian version of this competition, just to see how I’d fare, and to look at the process. Made it through the first couple levels of screening (from 3200 applicants, I was still in the hunt at 300 remaining) but then got filtered.

Some interesting bullet points if you’re thinking of applying, assuming the NASA questions are similar to the CSA ones:

(1) ham radio, morse code, or other amateur radio operator experience is an asset.

(2) Anything aviation or amateur rocketry is an asset, but in particular a pilot’s license. Anything aviation adjacent is still useful.

(3) Russian language (this might be changing in the current political environment)

(4) Experience in an “operational environment” – I suspect this is military jargon, but if you’d don’t field research as a scientist out of wilderness camps, or anything like that where you’re in a small group for work/adventure might apply here.

(5) Medical degrees, or advanced science degrees.

(6) Physical fitness and perfect vision

When I applied, my Russian sucked, my aviation experience was tangential (but copious), and I was a grad school dropout (from a planetary science program), so I didn’t float to the top. But it was enough to make it through the first layers.

There person who ended up winning was a medical-degree air force pilot. Hard to compete haha.

deegeese, w Webb directly images two planets orbiting white dwarfs
JoMomma, w Japan’s moon landing picture might be the space photo of the decade

“The lander was at most 10 meters off its mark, according to space agency officials, which is comparable to 11 yards or less.” Lol

Are we adding yards to clarify the distance for the benefit of American football players?

@HurlingDurling@lemmy.world avatar

As an American, I need this in hamberders in order to understand, don’t give me none of that commie metric system crap.

/jk

huf,

how much is that in sqrt(football field)? i’m lost.

f2sfljLhdtTZ, w NASA finally figures out how to open a $1-billion canister

OP you need to work on your emotions and stop the clickbaity titles.

@fossilesque@mander.xyz avatar

Haha, not my title, the article’s. I don’t change them too often because it disrupts my flow going through my RSS feeds while I select things I want to get into in depth myself, and I know publishers make these decisions for a reason. The text is pretty ok though. Feel free to downvote them.

ChicoSuave, w A black hole ripped apart a supernova

The saga started two years ago at Caltech’s Zwicky Transient Facility located at the Palomar Observatory in San Diego County, California. There, astronomers from Harvard University, the Smithsonian’s Center for Astrophysics, and MIT tasked a newly designed machine learning algorithm to scan the night skies for odd explosions in real time. Operators hoped that quickly flagging possible targets in this way could offer vital extra time for ground and space telescope array observations around the world. In July 2023, the AI system sighted one such event, which astronomers classified SN 2023zkd.

Comparative scanning of the night skies is a good use for AI.

stephen01king,

Yep, finally some proper use of AI instead of shoving them down our throats.

NightFantom,

There’s lots of good uses for AI, but people seem to equate AI with LLMs these days so I feel the need to point out that this is not a good use case for LLMs

Zachariah, w The New, Farthest Galaxy has Been Found by Webb. Only 280 Million Years After the Big Bang
@Zachariah@lemmy.world avatar

The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it’s sensed light from a galaxy only 280 million years after the Big Bang, the most distant galaxy ever detected.

Prior to the JWST, we had no infrared telescopes with large enough mirrors to detect light from the early galaxies. The Hubble can see near-infrared light, but only has a 2.4-meter mirror. It found only one galaxy from the Universe’s 500 million years. The Spitzer Space Telescope was a dedicated infrared telescope, but it only had an 85 cm mirror. Not only does the JWST have a much larger mirror, but detector technology has advanced so much that the veil obscuring the early Universe is being lifted one ancient galaxy at a time.

AbouBenAdhem, w Scientists hail ‘strongest evidence’ so far for life beyond our solar system

My theory is that the inhabitants of K2-18b are deliberately flooding their atmosphere with dimethyl sulfide to make it unappealing to humans.

HylicManoeuvre, w NASA Shuts Off Voyager Science Instrument, More Power Cuts Ahead to Keep Both Probes Going
@HylicManoeuvre@mander.xyz avatar

Oh noo I’m literally using Voyager to browse Lemmy

5714, w 'It's extremely worrisome.' NASA's James Webb Space Telescope faces potential 20% budget cut just 4 years after launch

Fermi- MAGA-Paradox

fallowseed, w Euclid reveals an Einstein ring around a nearby galaxy

‘nearby’ … speaking of relativity.
