[00:11:28] The first ever image of a black hole’s accretion disk was revealed this year. xkcd made a graphic showing the size of M87 compared to our solar system.
[00:15:30] NASA’s InSight lander has been trying to drill a heat probe into the Martian surface, but it’s been a heartbreaking story of progress and setbacks.
[00:19:38] DNA testing has found that the same variety of grapes used 9,000 years ago to make wine are still being used today by some winemakers in France.

[00:31:34] Australian scientists have developed an artificial intelligence algorithm that developed a new flu vaccine.
