Re: Science and Astronomy News

Sorry to change topic but there's a very nice recent paper about the possibility of having rings around exomoons and how to spot them in transit light-curves. It seems that there are some possibilities for detection. And importantly for SE: the configuration space for these systems is not so restric...

Re: The Gaia Mission

So, in just 24 days (13th of June, 2022) we will have the new data release from Gaia (this is called DR3). There will be no updates in astrometry (parallax and proper motions) since Gaia EDR3 (which was released in December 2020), but the new release will present low-resolution spectra for the first...

Re: Work progress 0.991

Massive WIP but a test I did earlier today.
That is simply spectacular. Congratulations.

38952 this graphic is my own, made for a course in computational physics I would love to hear you in that course. You are a wonderful teacher. And I always loved these simple computational models that anyone that knows a little bit of Python can reproduce to convince itself. Share as much as you li...

38881 That's awesome. Great animation. Not surprisingly, although the wave is somewhat intensified, it is quite nonuniform and does not come into a sharp focus at the antipode, thanks to the effects of Earth's oblateness and probably reflections as well. True that. There's now a beautiful visualiza...

38813 This is incredible. If you look closely in satellite imagery you can still see the effect of the pressure wave moving through the atmosphere A similar image processing now shows the pressure wave concentrating at the antipodes of Tonga (Algeria - Mali border) and the subsequent rebound: https...

38813 It was all so subtle that you'd never notice or think twice about it if you did not know to look for it. But it definitely happened. It was exactly like how clouds behave in footage of nuclear explosions when the shockwave passes through them, just slower. It was extremely weird. I'm still ki...

Old forum

38798 Does it even matter now when SE is dead? What is the purpose with this kind of passive aggressive comments? I mean, it has been well explained why SE has and always had a slow pace in regards to development, in quite a lot of posts . There's no need for you to restate your opinion on the matt...

Recently Derek Muller made a video about a fascinating topic that blew some minds apparently: [youtube]bHIhgxav9LY[/youtube] The video has become a bit controversial between fellow physicists. This time Veritasium seems to be just partially correct and he might have introduced a new missconception t...

SE kaput?

38619 Debate between whom? As far as I know people hope for the clouds since 2017. It's no matter if they discuss, it's only matter if developer is really doing it. Which I seriously doubt. Actually all of this looks like a dead project's forum with what is left of the fans. People that like SE hav...

COMMUNITY FEEDBACK - Fine-tuning SpaceEngine's realism with scientific updates

Claim: The probability of finding a wide-orbit (defined as from 5 AU to 15 AU from its star) ice-giant planet (broadly defined as massive planets) around any star is 1.4^{+0.9}_{-0.6} . Source: Poleski et al. 2021, Acta Astronomica Comment: This means that almost all stars should have at least one ...

COMMUNITY FEEDBACK - Fine-tuning SpaceEngine's realism with scientific updates

- SCIENTIFIC UPDATES TO IMPROVE REALISM IN SPACE ENGINE - WHAT IS THE PURPOSE OF THIS THREAD? I've wanted to do this for a long time. The goal here is to give accurate (better if it is peer-reviewed than not) and updated (recent, or if old at least giving context to the status of the debate) scient...

37998 Added articles about discovery of Neptune. Not sure about the first one, it is a mess of a many forum posts, but it have interesting information.Thank you for the explanation. It is clear for me You are right. And that's my fault. I need time to rearrange the information there and make a good...

Asteroids, meteors, and meteorites

37943 My understanding that, like in Tunguska, there is no evidence of a ground impact.  However, there could be still have been fragments reaching the ground which would leave no crater or craters small enough to get eroded away after this many years.  Such fragments themselves could have been ero...
