Zachariah, w NASA’s James Webb Space Telescope Finds Most Distant Known Galaxy
@Zachariah@lemmy.world avatar

Over the last two years, scientists have used NASA’s James Webb Space Telescope (also called Webb or JWST) to explore what astronomers refer to as Cosmic Dawn – the period in the first few hundred million years after the big bang where the first galaxies were born. These galaxies provide vital insight into the ways in which the gas, stars, and black holes were changing when the universe was very young. In October 2023 and January 2024, an international team of astronomers used Webb to observe galaxies as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. Using Webb’s NIRSpec (Near-Infrared Spectrograph), they obtained a spectrum of a record-breaking galaxy observed only two hundred and ninety million years after the big bang. This corresponds to a redshift of about 14, which is a measure of how much a galaxy’s light is stretched by the expansion of the universe

AlolanYoda, w The first train will be built on the moon, its real?

Not true at all, there were plenty of trains built on the Earth. The one on the moon will be far from the first.

This is fine 😬

    Meuzzin, w Hundreds of black 'spiders' spotted in mysterious 'Inca City' on Mars in new satellite photos

    They really expect us to believe this shit!? Those are definitely large alien spiders that are coming to the surface to mate and multiply as they prepare to attack Earth. I need to join up with United Citizen Federation, quick. I suggest you all do the same…

    Manos, w Hundreds of black 'spiders' spotted in mysterious 'Inca City' on Mars in new satellite photos

    TLDR: It’s gas deposits, not Martian spiders… yet.

    tiredofsametab, w Car-size asteroid discovered 2 days ago flies 30 times closer to Earth than the moon

    I know that's not how the phrase is meant to be read, but I can't unsee it as it flying separately by the earth and the moon and deciding to buzz one of the two a bit closer.

    Serinus,

    Than vs then.

    tiredofsametab,

    Hrm, so there's a third interpretation.

    Macallan, w After 30 years, I'm finally going to see a total solar eclipse. Also, Potato World is a thing.

    So, How was it? Did it live up to your expectations? Did you get any good pictures?

    Kichae,

    Pictures turned out ok! I should have done a dry run for my totality setup, as I wanted to do some bracketed exposures and assumed my DSLR would let me do that the same way in live display mode as it does in optical viewfinder mode, and it… didn’t. But the pictures I did get are a reasonable, if insufficient facsimile of the experience.

    As for the real deal… I’ll have to update everyone once I’ve processed it. It was clear as crystal, and a perfect day. I was totally unprepared in every way that mattered. I don’t yet have words.

    Macallan,

    Sounds like it was enjoyable. My son’s mother took him out of school and drove them 2.5 hours to go see it in totality.

    That seems like a lot of work for potato world.

    ReallyActuallyFrankenstein, w Fake Vs Counterfeit Eclipse Glasses. Did You Get Any?

    I am near the totality line, but stressing over this problem resulted in me giving up planning to see it.

    Seeing the eclipse directly would be cool, sure, but it will certainly be photographed extensively. I feel like permanently damaging my vision is way too likely buying something off of Amazon, and I don’t have a clue where else I can find them.

    BeardedBlaze,
    @BeardedBlaze@lemmy.world avatar

    For what it’s worth, I bought 2 pair at Lowes.

    ReallyActuallyFrankenstein,

    Thank you, where did you find them? Is there a display, or was it in a certain section?

    OsaErisXero,

    I got mine at home depot, there was a tub of them between the checkout and power tools. Like 2 bucks per.

    BeardedBlaze,
    @BeardedBlaze@lemmy.world avatar

    There was a tub of them middle of the walkway, close to the check out registers

    ArtieShaw,

    If you can get to an area where it will be in totality, you can see it without eye protection during that brief 2-3 minute window. The danger to your eyes is when it's at anything less than full total eclipse.

    Workaround: You can see the eclipse with a low tech solution of a pinhole camera. Google it for a better explanation, but

    -poke a pin through a sheet of paper.
    -during the eclipse, just hold it over something like another sheet of paper and you can see an accurate projection of the sun as the eclipse progresses

    It's actually pretty neat.

    But if your weather is good, consider going to a place where the eclipse will be total. I'm in the path, but I'm seriously considering driving several hours to a place with a better weather forecast. I've seen good quality photo and video of total eclipses since I was a child. And the people who showed it to me (astronomy nerds from a club) told me "it's not the same."

    ReallyActuallyFrankenstein,

    Thank you, yes…I’ll probably do the pinhole camera I suppose. I won’t be quite in totality, so definitely don’t want to risk it without protection. But I might try Lowes, from BeardedBlaze’s recommendation, since I assume there’s accountability in their distribution chain.

    I have a set of these: www.bestbuy.com/site/…/5869208.p?skuId=5869208

    I think they are pretty legit? They come with like, a whole kit and stuff…

    ArtieShaw,

    Celestron is a name I know and would trust. My dad had one of their telescopes and it was pretty nice. That was in the '80s though.

    KittenBiscuits,

    I’m driving about 15 hours (over 2 days, not all at once, lol) from Virginia to the totality path with a “just ok” forecast. I made a similar trip in 2017. It is definitely not the same as looking at a picture. It’s the changes in atmosphere, the insects’ behavior, the light quality all around you that make a totality viewing special. If you can make it somewhere with decent enough skies, you will be glad you did.

    I had no idea we could image exoplanets at a resolution high enough to be able to detect something like this, huh (and no I don’t mean the artist rendering)

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

    Nuhuh. I tried planning a trip a month ago and everything was sold out and airfare was astronomical. I’m gonna plan a trip for the Spanish one in 2026 a year early
