Black hole photographed for the first time.

My high school physics teacher said this would never ever happen. I bet him it would. If he's still alive, he owes me a soda.
Such potential!

Be prepared for a lot of scrolling: http://joshworth.com/dev/pixelspace/pix ... ystem.html. But it seriously helps for grasping all the immensity out there. (And that's only the Solar System. :| )

this phenomenon was discussed in that other thread, but here's a more spectacular pic (with explanation):

https://apod.nasa.gov/apod/ap190408.html
Explanation: What's happening in the sky? The atmosphere over northern Norway appeared quite strange for about 30 minutes last Friday when colorful clouds, dots, and plumes suddenly appeared. The colors were actually created by the NASA-funded Auroral Zone Upwelling Rocket Experiment (AZURE) which dispersed gas tracers to probe winds in Earth's upper atmosphere. AZURE's tracers originated from two short-lived sounding rockets launched from the Andøya Space Center in Norway. The harmless gases, trimethylaluminum and a barium/strontium mixture, were released into the ionosphere at altitudes of 115 and 250 km. The vapor trails were observed dispersing from several ground stations. Mapping how AZURE's vapors dispersed should increase humanity's understanding of how the solar wind transfers energy to the Earth and powers aurora.

Prediction: someone will use this as fodder for a conspiracy theory, like they did with The High Frequency Active Auroral Research Program (HAARP).

M87 is in the lower right (you can just barely make out the jet); the string of galaxies is Markarian's chain.

Geostationary satellite exploding, apparently:



Problems start to occur about 20 seconds into the video.

The Intelsat 29e anomaly comes amid a string of satellite issues in geostationary orbit, where large communications and observation satellites can look down at the same area of the planet without expending fuel to maintain their position. During the last two years, satellites such as AMC-9, Telkom-1, AMOS-5, Eutelsat-33B, EchoStar-3, and Galaxy 11 have all experienced on orbit anomalies.
weirdness means aliens. OTOH, two years is about how long Trump has been in office.

First gravity waves from the M87 black hole are reaching us.
