Time-Lapse of the Star S301 Orbiting the Black Hole in the Center of the Galaxy

What does it feel like to zoom around a spinning supermassive black hole? The featured video is an animation showing a time-lapse of 4 years of observations of the star S301 orbiting Sagittarius A*, the 4-million-solar-mass black hole in the center of our Galaxy. S301 was discovered in 2023 with the Very Large Telescope Interferometer of the European Southern Observatory, located in the Atacama Desert in Chile. Astronomers recently found that S301 takes approximately 8.7 years to go around the black hole and reaches speeds of 25,000 km/s. It comes closer to the black hole than any other stars detected before, at a distance similar to that from Saturn to the Sun. Because it comes so close to Sagittarius A*, S301 could be used to directly measure how fast the black hole spins and test Einstein's theory of general relativity. According to the theory, a spinning black hole drags the fabric of spacetime around itself, affecting the orbits of close-by objects.

The Elephant's Trunk in Cepheus
Image Credit & Copyright: Eddie Sgarbossa
Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long. The detailed telescopic view...

What if you could play a Begena without actually touching one?
I built a small web app that lets you play Begena using only the camera on your phone or computer.
The idea came to me after seeing people use cameras to create musical sounds with hand movements. I wanted to try making something similar with one of EOTC's instruments.
So I gave it a shot.
The app tracks the hand and detect finger movements. Each finger is mapped to a different Begena string, so by bending your fingers in front of the camera, just like you normally do, you can play the instrument in real time.
It uses MediaPipe for hand tracking, JavaScript for finger detection and Web Audio API to play the sounds. (I recorded each sound from my Begena)
Has 4 ቅኝትs (ሰላምታ ስለቸርነትህ ዋኔን አምባሰል) all in D major for now.
I’ve attached a demo video.
Try it: [BEGENA CAM]
Built with some AI assistance😁
Apparently, I could.
Would you actually try playing a Begena this way?
