Breaking: Global effort to film MRI of M87’s heart of darkness kicked into action with spring movie campaign
The Event Horizon Telescope (EHT) coalition is preparing a pioneering “movie campaign” to capture a moving depiction of the colossal black hole at the center of the Messier 87 galaxy. Spanning March and April, this coordinated effort stitches together data from a global network of radio telescopes to reveal the spinning disk that marks the edge of the event horizon—the boundary beyond which nothing can escape.
What’s happening and when
Over the coming weeks, the EHT will observe M87’s central black hole as the Earth’s rotation brings diffrent telescopes into view.The aim is to assemble successive snapshots into a time-lapse sequence, offering the most complete look yet at the black hole’s immediate environment. A full image can be built anew roughly every few days as viewing angles change.
Why this matters
Experts say mapping the black hole’s rotation speed could help discriminate between competing growth models. If growth is dominated by steady accretion, the hole should spin at extremely high rates. If mergers between black holes play a larger role, spin may be moderated by each collision.
Beyond spin, the campaign could illuminate how black holes launch jets—the remarkable beams that channel material across galaxies and influence star formation. Understanding jets helps explain how galaxies evolve and interact with their surroundings.
How it works
The EHT umbrella brings together 12 radio observatories across Antarctica, Europe, and Asia. In 2019,the network delivered the first direct image of a black hole’s shadow; this time,scientists aim to produce a moving sequence by combining observations as different stations capture the same region from varied angles.
Because M87’s central black hole weighs about 6 billion solar masses and spans roughly the size of our solar system, the photon paths shift slowly enough to be stitched into a coherent movie rather than a single still image.
what scientists hope to learn
By tracking the spin, researchers can test how black holes reach such staggering sizes and how jets are launched. The results could distinguish whether accretion or mergers dominate the growth of the most massive black holes in the universe.
As one leading researcher notes, black holes are not merely cosmic vacuum cleaners; thay are key to understanding the earliest galaxies and how they shape the cosmos. They play a critical role in regulating star formation and can influence the evolution of neighboring galaxies.
Data, delays and global collaboration
The operation will generate an enormous volume of data. Because processing requires moving hard drives from Antarctica to facilities in Germany and the United States, experts anticipate a delay before the wider public can view the results. The team expects to have enough data by Antarctic summer to begin deeper analysis and eventual public sharing.
Spotlight on leadership
Sera Markoff,recently named the Plumian professor of astronomy and experimental beliefs at Cambridge university,is a founding member of the EHT consortium. She emphasizes that the mission reflects a broader shift in how scientists view black holes—from feared voids to essential laboratories for understanding the universe’s history.
“We may be able to pinpoint how fast the black hole spins and how jets are launched—two central questions in our field,” she remarked. Markoff also highlights the human side of the science, noting her own journey into astrophysics—from science fiction to a career in research—and her hope to broaden participation in science.

evergreen context
Black holes are increasingly recognized as laboratories for studying gravity, quantum physics, and galactic evolution. The techniques used by the EHT—precise synchronization of multiple global telescopes and high-speed data processing—are advancing our ability to observe extreme environments in unprecedented detail. As technology and collaboration improve, similar campaigns may illuminate other cosmic heavyweights and test the limits of our understanding of space-time.
