subway76, w Jupiter's Clouds from Juno

The player must learn speed control and obstacle jumping to succeed in run 3, as even the slightest error can cause accidents and failure to complete stages.

subway76, w IC 342: Hidden Galaxy in Camelopardalis

Geometry Dash SubZero throws you right into the action with levels that don't mess around and graphics that are as cold as ice. You need to have great timing and quick reflexes—one mistake and you have to start over.

protist, w Why doesn't Argentina have more telescopes?

You’ll find most of Chile’s observatories are in the Atacama Desert, and that almost all of the Atacama Desert is in Chile. The high elevation, incredibly low humidity, and remote location make for dark, clear skies

Tollana1234567, w Astronomers discover fastest-ever spinning asteroid — over half a kilometer wide — using the world's largest digital camera stationed at the Rubin Observatory

half a kilometer isnt that big as far as most asteroid goes. the most devastating ones were over 10km.

I don’t care how big it is, spinning asteroids should not be allowed to use digital cameras.

Whiskey_iicarus, w Astronomers learn galaxies mature faster than previously believed after analyzing detailed images of 18 galaxies located 12.5 billion light-years away
@Whiskey_iicarus@lemmy.dbzer0.com avatar

A key finding from the survey is that the galaxies are maturing faster in several ways than researchers previously believed. For one, the galaxies are more chemically enriched than expected, which means they have produced more heavy elements, in particular carbon and oxygen, than was thought possible during this early age of the cosmos.

As galaxies evolve, pockets of gas within them condense and ignite into stars. The new stars churn out heavy elements like carbon, which then become building blocks for the next generation of stars. Ultimately, these heavy elements (referred to as metals in astronomy) are required to make planetary systems, and even humans, in the case of our own solar system.

“How do metals form in less than 1 billion years? It was a surprise to see such chemically mature galaxies,” Faisst says. “It’s like seeing 2-year-old children act like teenagers.”

Why is this so different looking compared with the previous Jupiter pictures?

antonim,

Perspective (this is a view from up/downsides, where the clouds/atmosphere behaves differently), and, I presume, different colour processing (fitting the colour spectrum into what is visible to the human eye, which is not necessarily straightforward).

Good question. I went looking for a source and am going to stop now but here are some links.

I suspect the source is one of the social media links here:

www.missionjuno.swri.edu/junocam/processing?id=17…

It doesn’t give much info for the specifics of how it was processed:

This processed view enhances cloud-top texture and reveals swirling filaments, compact vortices, and bright high-altitude clouds embedded in a chaotic flow.

It does list the source data for processing as this:

www.missionjuno.swri.edu/junocam/processing?id=JN…

Here is a brief summary of the instrument from one of the groups involved with the Junocam:

oracle_of_vp,

Wow many thanks for the background info. The picture really is amazing 😊

You can see that it’s a shot from one of the poles. Also, keep in mind that while the patterns in weather last a long time, they aren’t set in stone. The way Jupiter looks slowly changes over time, just like any other planet. Even the Big Red Spot hasn’t been there forever, and will eventually disappear.

Akt0, w Question about lunar calendars

But we don’t have a ‘Year 0’, it goes 1BCE to 1 CE.

Lunations are only ~29.5 days long, between specific moon phases. They still count one year as 12 lunations, ~354 days. Right now is Rajab on the Islamic Calendar, but that’s still the month, not the moon. According to the Farmers Almanac, January is the Wolf Moon, taking from both Native American and European Colonial traditions.

Yes, there are multiple counts. Rajab is the 7th month of the Islamic (Hijri) Calendar, AH 1447, while Tevet is the 4th month of the Hebrew Calendar, AM 5786.

Hopefully this helps, and I understood you correctly. If not, Wikipedia has charts of the current date according to multiple calendars when looking at specific calendars, like the Islamic Calendar, or you can look more at Lunar Calendars, and the differences between Solar, Lunisolar, and Lunar Calendars.

Awesome document! I never realized it was only so late, I guess there is a difference between balloons and “serious record-breaking ballons”!
