Hey folks!

We have reverted the bug that was causing magnitudes to display wildly incorrect values. The change was intended to be an accuracy improvement, but it wasn't playing nice with existing calculations. While fixing the bug, we determined that proper integration will affect SpaceEngine's procedural generation, so to preserve your locations and keep the universe stable, we will delay releasing that improvement until a future major version.

The purpose of this Beta is to ensure magnitudes have been returned to the values you currently see on the public branch. Please file bug reports in the usual channels (Bug Reports on the official Discord and Troubleshooting and Bug Reports on the Steam forums) with any inconsistencies you find!

• Removed apparent magnitude fix that was causing multiple bugs

We have received a lot of reports of issues with the display of magnitudes for planets and other non-Star objects after the last release. We have rolled back to the previous version on the main branch while we work on a fix. Thank you for your patience!

The JuMBO update is still available on the Beta branch, if you would like to explore it in the interim:

Hey folks!

We're bringing your monthly dose of catalog updates, featuring several recently discovered JuMBO's in the Trapezium cluster!

If your first thought was of overly large trapeze swings, you're not alone. Dr. Megan has written up a blog post explaining these rogue pairs and featuring one among the recent discoveries! Read all about it here: https://spaceengine.org/news/blog240924/

• Updated the exoplanet and host star catalog (new planets and hosts), including new Jupiter Mass Binary Objects (JuMBOs)
  
• Fixed duplicates in the white dwarf catalogs, so white dwarf binaries won’t have an extra white dwarf at the barycenter
  
• Fixed an assortment of one-off errors in object properties in the catalogs
  
• Fixed a bug where planemo displayed large numbers for daylight hours at equator and an annual fraction of polar day at current latitude
  
• Fixed an issue with AgX tonemapping name

Hey folks!

Thanks again for your diligent Beta testing! Today we're bringing the High-Resolution Screenshot Tool to public, enabling you to take a screenshot of any reasonable (or unreasonable!) resolution, even if you have less than stellar hardware! The new tool can be found on the left tool bracket and shares an icon with the default screenshot button.

In case you missed it: we celebrated five years on steam with the Beta launch of the new tool; the accompanying blog post includes a brief look back on our development as well as a guide on using said tool. Read up on it here: https://spaceengine.org/news/blog240611/

We're still on the lookout for any bugs that sneak through. Keep us posted in the Troubleshooting Discussion threads!


[h4]New Additions[/h4]

• Fixed a bug in the Star Browser where planet/moon temperature and temperature class results didn't match the actual system when visited
  
• Fixed several bugs and issues with the high-resolution screenshot tool

[h4]Additions from Beta[/h4]

• Added high-resolution screenshot tool (See linked blog post for a how-to!)
  
• Improved integration of Settings and Tools windows with the main menu
  
• Updated exoplanet and host star catalog
  
• Updated binary asteroid catalog
  
• Improved the appearance of Eris and Sedna (for real this time!)
  
• Miscellaneous catalog fixes, such as the distance to galaxy and black hole S5 0836+71
  
• Added button to video capture dialog to open the output folder
  
• Added missing gamma correction to several tone mapping options
  
• Added new tone mapping options: AgX Punchy, Reinhard SE, Rec 709, and sRGB
  -Rec 709 and sRGB are mainly for reference, they are not designed for HDR content and clip harshly with bright pixel values; manual exposure adjustment recommended for best results.
  
• Fixed some settings not saving while in the main menu

Hey folks!

It's been five years to the day since SpaceEngine was released on Steam. We're celebrating this milestone with the addition of a high-resolution screenshot tool, letting you capture the universe in greater detail than ever before!

We've put together a blog post with a how-to for the new tool, as well as a retrospective of our development! Check it out here: https://spaceengine.org/news/blog240611/


We're also expecting some bugs with this Beta, so be sure to report any you find in the Troubleshooting and Bug Reports Discussion tab on Steam or #bug-reports on the official Discord! (Remember to include as much detail as possible!)

• Added high-resolution screenshot tool (See linked blog post for a how-to!)
  
• Improved integration of Settings and Tools windows with the main menu
  
• Updated exoplanet and host star catalog
  
• Updated binary asteroid catalog

Thanks to everyone who partook in the Beta! The public release has a few more additions which will be highlighted along with the patch notes from the Beta. Dr. Megan highlighted one of the new exoplanets, as well as two new black hole systems, in celebration of our new celestial neighbo(u)rs!

Hey folks!

Hope you enjoyed the eclipse! The ongoing refactoring process still demands high commitment, but we wanted to get something out to address the new science and add our newest exoplanetary neighbors as our work continues!

Dr. Megan's pick this round is our newly discovered neighbour, TOI-715 b. Discovered by the Transiting Exoplanet Survey Satellite (TESS), this super-Earth is only 137 light years from our Solar System. TOI-715 b orbits within a conservative habitable zone around its cool, red host star, meaning it could potentially host liquid water! That's not to say TOI-715 b is a hospitable world; it is on a tidally locked orbit, so the same hemisphere always faces its host star, giving it a hot front-side and a cold back-side. TOI-715 b is 0.08 AU from its host star (closer than Mercury is to the Sun!), and its orbital period is only 19 days!

This may just be the beginning of the exciting news from the TOI-715 system, as it is suspected that another, smaller planet may also be present. If this second planet is confirmed, be sure to be on the look out for its future appearance in SpaceEngine!
