For the first time, we’ve seen the heart of our galaxy. The Event Horizon Telescope captured an image of Sagittarius A*, the Milky Way’s supermassive black hole - 4 million times the mass of our Sun. A glowing ring of gas outlines its shadow, confirming Einstein’s predictions. shorturl.at/7eFBF
We finally have an image of the black hole at the heart of the Milky Way
New observations from the Event Horizon Telescope reveal the turbulent region around our home galaxy’s black hole, Sagittarius A*, in extreme detail.

New evidence of ancient hunting rituals reveals what we consider "modern" human behavior to have existed much earlier than previously thought, and being used by our evoluntionary relatives like Neanderthals. Humanity's capacity is maybe more than we thought.

Ancient horse hunts challenge ideas of ‘modern’ human behavior
An archaeological site in Germany suggests communal hunting and complex thinking emerged earlier in human evolution than once thought.

The Doppler Effect
Stage 1: the car approaches, sound waves are compressed in the shrinking space between us, and the pitch sounds higher.
Stage 2: The car is level with me and the pitch shifts
Stage 3: The car moves away from me, the sound waves stretch out and the pitch grows lower and fades away.

Dolphins have long been called the smartest animals but they now help the military using their natural sonar. It has proven effective in detecting underwater mines and divers. I've learned about echolocation via bats since I was young, but we can now use it as part of our technological advancements!

I've never seen a pink dolphin in real life, but I would love to one day. I always wondered what made them that hue. I always thought it was just the boto dolphins that were pink, but turns out it can happen to bottlenose dolphins too, but it's not permanent for them. It happens in excitement.

Arctic terns use an avian magnetic compass to guide them. This built-in natural compass uses Earth's magnetic field lines to tell the bird where to go. Light enters the eyes and triggers certain chemical reactions depending on the direction of the magnetic field.

Took a walk through Rowlett park and couldn’t help but looking up throughout most of it. The sky does crazy things and I’ve found clouds and their classifications interesting since I was a child. I would classify this one as cirrocumulus, a mix between light and airy cirrus and large puffy cumulus.
