TLDR: it’s the hot gas filaments between galaxies that they confirmed

That’s some hard long science right there.

I always love seeing the telltale Webb diffraction spikes. Great new pictures.

maegul, do astronomy w Euclid discovers a stunning Einstein ring
@maegul@lemmy.ml avatar

I’m confused about what exactly the ring is in the image or the main image at least. There seems to be an enhanced image in the article that highlights the ring more clearly as an outer edge, which makes sense (I suppose).

But I don’t understand what I’m to make of the top image. It’s the diffuse light part of the ring?

Balthazar,

You need to zoom in to the center of the bright elliptical. It would have been easier to see without zooming if they’d subtracted off the elliptical.

Ah yes! Thanks! The enhanced image does day “close up” after all! A bit lazy of me!

Very cool though! A zoomed inset in the main image would have helped I think.

Buzztiger, do esa w Farewell, Gaia! Spacecraft operations come to an end

So Gaia relies on maintaining very accurate pointing at the stars while measuring their position. For this purpose it uses special cold gas (Nitrogen) thrusters with very low flow noise. These cold gas tanks are now empty and Gaia simply cannot continue to operate.

proper, do esa w Juice confirms that Earth is habitable
@proper@lemmy.world avatar

“We are obviously not surprised by these results… it would have been extremely concerning to find out that Earth was not habitable! But they indicate that MAJIS and SWI will work very successfully at Jupiter, where they will help us investigate whether the icy moons could be potential habitats for past or present life.”

The number of galaxies present in JWST images always makes me want to puke

    Zachariah, do esa w First detection of negative ions on the Moon
    @Zachariah@lemmy.world avatar

    The first ESA instrument to land on the Moon has detected the presence of negative ions on the lunar surface produced through interactions with the solar wind.

    The European team working with the Negative Ions at the Lunar Surface (NILS) instrument confirmed the success of this scientific mission that flew to the far side of the Moon aboard the Chang’e-6 spacecraft.

    The discovery of a new component of plasma at the surface of the Moon opens a new window for space physics and for human and robotic missions in an era of renewed lunar exploration.

    Sniff, our most successful scientific Spacecraft by publications. The new Voyage 2050 programme certainly provides science topics that could lead to a worthy successor.

    @troyunrau@lemmy.ca avatar

    Godspeed! I don’t think Ariane 6 will go down in history as a successful rocket, mostly on account of the shift in economics forced on the rest of the industry by SpaceX. But I do get excited for debut launches – some very clever people worked very hard on this. :)
