Did you know that black holes are spinning?🌀🔎 To find out just how fast, EHT researchers used AI to connect simulated data to actual EHT measurements of M87 and SgrA*. They found that the black hole in SgrA* spins almost as fast as physically possible!

Could you starwatch all night? The IRAM 30-m telescope can!✨🌌 This observing mode is called VLBI, which involves telescopes around the world viewing the same object at the same time, such as a black hole, then combining the data to get super-high-resolution images.

As we've seen this Black Hole Week, black holes have gone from theory to image, from mysteries to measurements. Now, the EHT is entering a new era, where more telescopes around the world — and maybe in space — will capture time-lapse “movies” of black holes. Popcorn, anyone?🎥🍿

About 27,000 light years away, with a mass of more than 4 million Suns, lies the Milky Way’s supermassive black hole Sagittarius A*. If you were to approach it, you’d be deceived by its size - the shadow is roughly twice as big as the black hole’s actual surface!⚫️

Behold Perseus A, one of the closest active supermassive black holes, at 230 million light years away. Composite images like this one from the NRAO, Chandra, Hubble, and the EHT can help us study black holes and their environments, which influence each other.🛰️

Centaurus A is the closest radio galaxy to Earth. Radio galaxies feature two-sided jets that are ejected from the galaxy’s central black hole and measure up to millions of light years long. These jets are theorized to spread energy and affect the growth of their host galaxies.💫

Happy Black Hole Week! This is Messier 87; despite being located about 55 million light years away, the EHT peered at its beating heart in 2017 for its first image. Did you know that the location of the brightest region around the black hole, and its shadow, can change yearly?🔭

Last but not least, say hello to the SMA, also located on Hawaii's tallest mountain, Mauna Kea🌈🌋!. The telescope's eight 6-meter radio dishes all work together to act as one telescope that studies black holes with the EHT, as well as the births of planets, stars, and galaxies.

You shouldn't stare directly at the Sun - but the JCMT can☀️! A unique membrane in front of its antenna lets radio waves through while reflecting visible and near-infrared light, allowing JCMT to make daytime observations. JCMT sits on the dormant volcano Mauna Kea in Hawaii🌺.

Skyscrapers aren't the only towering structures in Seoul, South Korea - the KVN Yonsei telescope makes its home in the bustling city🇰🇷🏙️. The telescope is the furthest east in the EHT, filling an important gap between Europe and Hawaii to make more accurate black hole images.

There's no room for a fear of heights at APEX - at 5100 km high in Chile, it's one of the highest observatories in the world!🌄 . As the largest telescope for its target wavelengths in the southern hemisphere, APEX helps map regions like the Galactic Plane and Galactic Center.
