AstroKobi Story of November 2, 2026Trari Newsroom

Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.

How Big Is The Biggest Black Hole?

Shrink the Sun into a black hole, and AstroKobi's animated comparison makes it just six kilometres wide. That is only the starting point of "How Big Is The Biggest Black Hole?", a brisk climb through objects whose proportions quickly leave familiar landmarks behind.

The host moves from the stellar black hole Gaia BH3 to Sagittarius A* at the centre of the Milky Way, then M87* and Phoenix A. The last is presented as a possible heavyweight at around 100 billion solar masses, with its event horizon supplying the video's most dizzying scale comparison. In the comments, several viewers ask why TON 618 is absent, turning the size tour into a discussion about what belongs on the list.

The black-hole upload is the most-watched of AstroKobi's two new videos, reaching roughly 166,000 views. "The Moon Is Leaving Us" supplies the other celestial question. The black-hole explainer also has the strongest daily momentum among the channel's active videos, followed by October's "The Sun Saved Your Life" and "The Apple In An Infinite Box Theory".

AstroKobi added 10,000 subscribers over the week, even as daily viewing currently sits a little below its usual level. Among nearby science channels, CrunchLabs had a larger week for views and subscriber growth, while Technology Connections is enjoying a particularly busy spell of daily viewing. For AstroKobi, the week's freshest draw is a familiar teaching device taken to cosmic extremes: start with the Sun, then keep widening the frame.

We probably won’t reach any of these in the far future, only watching it with telescopes, hoping for a day we might be able to get close.
