Swift J011511.0-725611 - an rare SMC BeWD binary

3 days after discovery (yes, its that close), a new binary will show up - and that one is:

White dwarf with giant blue star

Disk occultation of the main star, 2MASS J01151085-7256102.


The main source is the discovery paper, which is Kennea et al. 2021.

Re: Project Sisyphus - Texturing/painting every exoplanet known

Isnt that one of the principles of Project Sisyphus? Each and every person has its own version and its own opinion of what each planet looks like. Its no problem if a person does a planet someone else did, since they probably have a different opinion on it.

Re: Spacecrafts for Celestia

I'm preparing the trajectory of the Fly Safe spacecraft to release on this thread... which turns into political discussion out of nowhere! Please tell me we can put the thread on topic again... What the heck did we do to deserve this...

Re: Spacecrafts for Celestia

Yeah, albeit last time i checked, Starship (the grain silo-looking crewed second stage) is 50 meters tall, and its 2017 design had an pressurized volume of ~825 m3... So its not small at all!

This is not accurate at all, because magenta does not exist, let alone being an blackbody color! Its an illusion of the human eye due to us not being able to see non-visible light.

Re: Which are the most underdeveloped parts of Celestia?

Performance improvements with extremely large catalogs, and render limits for hyperdistant quasars.

Re: Hypothetical: Specific Rogue planet. When could be its discovery date given its orbital, size, and albedo parameters?

The rogue planet itself would had likely been discovered in the 1970s or 1980s, with the discovery survey likely being the Catalina Sky Survey (limiting magnitude: +21.5). Its moons would had likely been found at around the time Hubble was first operational, so around the early-to-mid 1990s.

For non-gamers, its like having many variants of the same thing. For example, CO has around a dozen variants of jovian textures, from Pioneer 10/11 in the 70s, to Juno and Hubble today.

Re: Pictures from Celestia

Trappist, that's enough. Could you please be on topic and post "Pictures from Celestia", like the title of this thread says and like what I'm about to do, instead of pestering everyone to release their stuff in 5 seconds?
