Black holes are generally considered to be spherical in shape, with their event horizons appearing round. However, rapidly spinning black holes may have slightly oblate shapes. The singularity at the center of these black holes could potentially be disc-shaped rather than a point. Future advancements in quantum gravity theories may provide further insights into the nature of singularities. Understanding the shape of black holes remains an evolving topic in astrophysics.

I want to know what is the shape of a Black Hole? Is it round like a globe, or is it flat or oval shaped?
For all practical purposes, black holes are spherical. The event horizon of a rapidly spinning black hole may be slightly oblate. The putative singularity at the center of a rapidly spinning black hole could be disc shaped, as opposed to a point. Chances are good, however, that singularities will be resolved by a correct treatment of quantum effects [i.e., a theory of quantum gravity].

Partial solar eclipse from Twizel, South Isl., New Zealand ...
almost missed it due to cloud, didnt see max at 0710 NZST as it went back into cloud.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons.
Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
