New EHT images show M87*’s magnetic fields changing: turning one way in 2017, settling in 2018, then reversing by 2021. The flip may result from internal magnetic structure and external effects like a Faraday screen. Credit: EHT Collaboration | Animation: Amy C. Oliver (CfA)

What are the stripes in the images of M87*? They show the direction of polarized light. This animation shows how M87 would look over the years through a polarizer- like the filters in reflex cameras or 3D glasses. Animation: I. Martí-Vidal (Univ. Valencia)

The new image of M87* just released today comes to life in this stunning animation, revealing its incredible evolution over the years! Watch closely and see how this mysterious supermassive black hole changes over time. Credit: EHT Collaboration | Animation: Saurabh (MPIfR)

Did you know? ✈️

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* is spinning almost as fast as physically possible! www.aanda.org/10.1051/0004...

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.

"You asked, we answered!🫡 Here are some of our favorite questions from last Friday's Reddit Ask Me Anything for #BlackHoleWeek2025 Have more questions about the mysteries of black holes❓Read the full thread here: www.reddit.com/r/askscience...

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?🎥🍿

Do you have burning black hole questions? Are you curious about the process of astronomy imaging and engineering, space physics or theory? To wrap up Black Hole Week, join the EHT for an Ask Me Anything on Reddit this afternoon from 3-5 pm ET! redd.it/1kig9rj

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?🔭 #BlackHoleWeek2025

Ever wonder how to study the nature of spacetime and the edges of physics? These mischievous black holes have a clue! Join the Event Horizon Telescope for #BlackHoleWeek2025, May 5th-9th, as we highlight pieces of the black hole science jigsaw puzzle.🌟 #astronomy #astrophysics #blackholes

Observing the sky for days at a time is hard work - for pets and humans🐈! Here are some of the incredible astronomers who made the 2025 EHT Observing Campaign a success.🌟 See more on our Instagram: www.instagram.com/p/DI4xFR0NSC...

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.

6 years ago this week, the Event Horizon Telescope released the world's first black hole image🎉🎊 #blackhole #astronomy #astrophysics

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.

NOEMA, located in the French Alps, has "vision" sharp enough to see someone's computer 500 km away in Venice👀💻. Its 12 dishes operate together like a single dish with a diameter of 1.7 km, making NOEMA the most sensitive array of its kind in the northern hemisphere.

Astronomers at the Greenland Telescope (GLT), located 1200km inside the Arctic Circle, can experience temperatures down to -65ºC on clear nights🧊🇬🇱. GLT has widened the EHT's earth-sized telescope lens beyond the North Pole, enabling higher resolution pictures of black holes.

Located on Mount Graham, AZ, the Submillimeter Telescope has withstood forest fires in 2017, 2004, and 1996 to take observations of the universe⛰️🚒. Astronomers aren't the only ones interested in the telescope - amid the charred trees, 4 deer were spotted roaming this week.

Let's travel to Spain's sunny Sierra Nevada mountains with the IRAM-30 Meter Telescope, the most sensitive single dish in the EHT🇪🇸! The instrument is adjusted to the width of a human hair and weighs about 800 tons, far more than a fully loaded Airbus A380 airplane.

At Chile's Atacama Large Millimeter Array (ALMA), the more the merrier - they have 66 telescopes!🇨🇱 During EHT observations, this army of radio dishes has their antennae oriented to behave as a single instrument. Its sensitivity helped determine the shape of a black hole's ring.

This snowy site is the 12-meter telescope at Kitt Peak, Arizona❄️. While beautiful, snow and rain cause water vapor which absorbs the electromagnetic waves that radio telescopes capture. As a result, radio telescopes are built at high altitudes - Kitt Peak soars 1900 meters up!

Meet the Large Millimeter Telescope (LMT), located on a dormant volcano in Sierra Negra, Mexico🌋🇲🇽! The LMT's dish is as long as an Olympic sized swimming pool and its distance from other EHT telescopes has made it crucial in observing the shadows of black holes.
