A midnight photo of the Sun, taken through the Earth, for AstroKobi
Kobi Brown's one new video follows the neutrino from a physics crisis to an image shot with the camera pointed at the ground.
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.
This Photo Should Not Be Possible
Among the science channels nearest AstroKobi in size, most are running above their usual pace right now, PBS Eons, Technology Connections and Physics Girl among them, while CrunchLabs and Astrum are a touch quieter than normal. AstroKobi sits right beside Hank Green at around 3.2 million subscribers.
Kobi Brown posted one video, and its premise is a good one: a picture of the Sun taken at midnight, with the camera aimed straight down. The description says a physicist of a century ago would have called it impossible, and the chapters walk the long way round to explain it. Physics in trouble, the birth of a ghost, three flavors, a new messenger. The tags give the ghost away: it is the neutrino, the particle that passes through the whole planet almost untouched, which is exactly how sunlight of a kind can arrive from below your feet. Malte Ullrich and Mikael Jutbo did the animation, and Brown is credited with everything else.
It went up only hours ago and already has more than eleven thousand views. The channel's real momentum belongs to older work, though. "The Fastest Star Ever Discovered", a month old, is closing on two million views and still draws the most each day, with the dark matter video about half its pace and "The True Scale Of The Universe" not far behind that.
A star, dark matter, the scale of the universe and now a ghost particle: the last month on this channel has been a tour of the things that are hardest to see.

The first image of the Sun made with neutrinos came from which Japanese detector?
Super-Kamiokande, a huge underground water tank in Japan, produced the well-known neutrino image of the Sun, which it can record even at night through the Earth.
