About Ho'oleilana
The light we see from it set out 0.936 billion years ago, when the universe was 12.9 billion years old (redshift 0.068).
The map lists it as a large-scale structure and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.
Its distance or nature is debated, and the map shows one published value.
A candidate single baryon-acoustic-oscillation shell about 1 billion light-years across (Tully et al. 2023).
Key numbers
| Distance (comoving, today) | 0.967 billion light-years (296 Mpc) |
|---|---|
| Redshift z | 0.068 |
| Light travel time | 0.936 billion years |
| Universe's age when this light left | 12.9 billion years |
| Distance method | redshift (Planck 2018 cosmology) |
| Supergalactic coordinates | SGL 70.6°, SGB +31.2° |
| On the map | The dashed circle marks its approximate size around its centre. Structures this large have no sharp edge, and the circle is not drawn to an exact shape. |
| Size | about 1 billion light-years across |
Where it is

From Wikipedia
In cosmology, baryon acoustic oscillations (BAO) are fluctuations in the density of the visible baryonic matter of the universe, caused by acoustic density waves in the primordial plasma of the early universe.
