2024 Digital Universe Data Update (#3335)

Browse Source 
* Update 2dF.asset

* Changes to the filename metadata, as wekll as the description.

* 2024 DU updates.

* Apply suggestions from code review

Co-authored-by: Alexander Bock <mail@alexanderbock.eu>

Apply suggestions from code review

* Changes to the asset descriptions, the GUI path, and some of the settings.

* Fixed minor error in a variable name.

* Wrote the individual descriptions for each asset.

* Adjusted the size (brightness).

* Update identifier to one that works

* Update asset versions and correctly format asset files

* Reset exoplanet rings size

To make them visible when viewed further away, e..g at the distance of the radiosphere, and make the Kepler FoV more apparent

* Clean up scale variables

* Line-break long descriptions

As long as we expect users to manually edit files, they need to be readable

* Remove letters that sorts the grids by size

* Split allsky into two assets

Remove asset that was split in two and update DU meta asset

* Replace dwarfs texture with generic point texture resource

* Remove all DU version comments, to reduce "noise"

These would be confusing to our users

* Some final cleanup

* Remove commented radii

* Local Universe -> Nearby Surveys

* Remove asset versions

* Apply suggestions from code review

Co-authored-by: Alexander Bock <alexander.bock@liu.se>

* Remove background setting (non-existing) for spheres

* Rmeove commented out lines in star orbits asset

They are confusing, and the label file they refer to does not exist

* Apply suggestions from code review

* Fix some missing line breaks

* Update sync identifiers to match updates in BigBang PR

* Reuse point textures from the same resource instead of having one copy per dataset

The texture used is the same

* Set brown dwarfs dataset version to 1

* Update bookmarks file with updated star poistions

Description = [[Hydrogen-alpha is a term that describes light from the ground state of
the hydrogen atom. When an electron in an atom moves from one energy level to a
higher one, we say the atom is excited. When the electron moves back down to the
lower energy level, light is released at a wavelength commensurate with the energy
between the two levels. For the H-alpha line, this energy difference translates to a
wavelength in the extreme red end of the visible spectrum. This survey of the sky is
a snapshot of light from this wavelength.
One distinctive element of the sky at this wavelength is the presence of large,
spherical bubbles surrounding hot stars. Many nebulae and star-forming regions are
visible, including the Great Nebula of Orion. We also see that galaxies emit H-alpha
light, including the Andromeda Galaxy and the faint M33, the large face-on spiral in
Triangulum, and the Large and Small Magellanic Clouds (LMC and SMC) in the southern
sky. Census: 1 all-sky image.]]

signals in space. Before television carrier waves, early-warning radar first used
in World War II, and the detonation of atomic weapons, Earth was radio-quiet to the
universe (AM and FM radio signals bounce off the atmosphere and do not escape it).
After the use of these and other radio emitters began, in the late 1930s and early
1940s, signals were able to escape the atmosphere and travel into space at the speed
of light. Since then, we have been broadcasting to the universe. We mention earlier
that this is the theoretical extent of these signals. In reality, these signals
will dissipate rapidly into the ambient cosmic noise of the universe. All light
falls off as the square of the distance, and radio waves are no different. The
signals that emanate from Earth are likely lost in the noise before they leave the
solar system, but the radio sphere remains a visually compelling astronomical
concept.]]

billion objects, and obtained spectra to more than 4 million objects. This is
not an all-sky survey, so there are large parts of the sky that remain
unobserved, which produces the bow tie distribution and the black areas where
there surely are galaxies, but we have yet to observe them. These galaxies
appear to extend beyond the 2dF survey to distances that exceed 5 billion
light years. However, the weblike structure of clusters, filaments, and voids
seems to fade by about 2 billion light years. Beyond this distance, the
completeness of the survey drops so that only the intrinsically bright

Description = [[Cosmic voids are vast, empty spaces where there are either no
galaxies, or very few galaxies. They are associated with cold spots in the cosmic
microwave background (CMB) light, the earliest picture we have of the universe.
Those cold spots in the CMB evolved into large voids, some as much as 300 million
light years in diameter. Labels roughly denote the location of cosmic voids in the
Tully galaxies. Voids are only visible with motion cuing as you spin around these
data. The labels help to guide the eye and provide sign posts for the largest voids
in our cosmic neighborhood. Census: 24 cosmic void labels.]]

not massive enough to end in a neutraon star or black hole will evolve into a white
dwarf. This is the ultimate fate of over 95% of the stars in our Galaxy. As the
star is dying, the outer layers will expand out and the gas will glow and become a
planetaery nebula, while the core of the star transforms into a white dwarf. Census:
