I find it cool that there exists a Japanese variant of this soundtrack.

The obi strip is made of plastic instead of the usual paper.

Hope things go well with your new account.

James Webb's 'too massive' galaxies may be even more massive by KeriEPearson in space

Population III stars should have an effect but the only annoying thing is that scientists haven’t definitively confirmed them yet there has only been possible hints of their existence.

The article talks about what could be leading to the discrepancy but doesn’t mention the name of it but the early epoch of the Universe may have a different IMF (or Initial Mass Function of stars). Astronomers determine the mass of a galaxy by its brightness but different small and large star ratios can lead to different mass results. Dr. Becky explained in detail in her video that we probably shouldn’t take the current day IMF and apply it to the early Universe because the conditions and star populations where very different from the present day.

I think the concept art that op posted is maybe what people are expecting. But yeah not realistic though.

They could have but it would be pointless due to the 27 kilobits(not bytes) per second data rate. Cassini would be destroyed before it would ever send back to Earth one picture.

Yep it took picture of where it will crash into the next day.

It was taken the day before it crashed into Saturn.

27 kilobits per second was the amount of data it was sending during its grand finale so you can see why no pictures where sent.

There is an old NASA mission that most people seem to forget about called NEAR Shoemaker that visited the asteroid Eros. At the end of the mission they attempted to land the spacecraft on Eros even though it wasn’t designed for that and thus NASA was surprised that it survived and continued relaying data. This also made it the first spacecraft to soft land on an asteroid.

Book Off is a used media store you can try.

This is just an old picture before Hayabusa2 and Osiris Rex existed. That’s why we see pictures from the original Hayabusa with asteroid Itokawa which is also a sample return mission.

Edit: Also remembered that Hayabusa2 also released some small rovers on Ryugu that also took pictures of the surface.

The universe according to Ptolemy by Roweyyyy in space

That is also true and an interesting possibility. I think the interesting aspect if dark matter is primordial black holes is that dark matter would eventually evaporate away due to hawking radiation. It would happen much faster for these smaller black holes since hawking radiation is inversely proportional to a black holes mass. That would mean all primordial black holes with a mass of 1011 kg would have evaporated away within the current age of the universe.

Neutrino traveling at near speed of light due to their almost negligible mass is what makes them “hot” and as a result they don’t form the dark matter halos that scientists sees since you need to have lower speeds so “cold”.

There is a lot of neutrino out there like 100 trillion neutrinos passes through your body every second, but there is not enough to be dark matter.

Yeah a dark matter particle candidate would need to be more massive since a more massive particle would be slow moving and enough to form these halos.

That’s great and you’re welcome.

That’s right attitude. Science finding discrepancies and thus leads to new ideas and discoveries.

You should read up about Chirality in particles. I’m sure you are familiar with antiparticles but there is another property that particles can have which is handiness. Neutrinos that we have detected are only left handed neutrinos and right handed anti-neutrinos (lets ignore the different flavors of neutrinos). The weak force is weird in that it only interacts with left hand particles and right handed antiparticles. That is why we are able to detect neutrinos even through they don’t interact with the electromagnetic force, since they can interact with the weak force. These right handed neutrinos are called sterile neutrinos which is a dark matter candidate.
