How Do You Photograph a Black Hole? The Telescope the Size of Earth Is Still Rewriting the Answer.

On April 10, 2019, the Event Horizon Telescope revealed the first image of a black hole: a lopsided orange ring around a dark shadow in the galaxy M87, 55 million light-years away. The image was not a photograph in any conventional sense. It was assembled from radio signals captured by dishes on four continents, synchronized by atomic clocks, and combined into a virtual telescope with the resolving power of a single dish the diameter of Earth. Here is how the impossible image gets made, why the Milky Way's black hole took three more years to resolve, and what the collaboration is still discovering about magnetic fields, relativistic jets, and the edge of spacetime.

Physicists Finally Built a Quantum Material Predicted a Decade Ago. It Conducts Electricity Only Along Its Edges.

For more than a decade, a two-dimensional topological crystalline insulator existed only in equations. Now researchers at the University of Jyväskylä and Aalto University have built one: a two-layer film of tin telluride on niobium diselenide that blocks electricity in its interior while conducting it along its edges. The compressive strain from the substrate stabilizes the topological phase, and the band gap, larger than 0.2 electron volts, should keep the edge states working at room temperature.

The Fastest Object Ever Built Keeps Touching the Sun. Parker Solar Probe Just Made Its 28th Close Pass.

The fastest object ever built has now flown through the Sun's outer atmosphere 28 times. On June 8, 2026, Parker Solar Probe matched its own records, 3.8 million miles from the solar surface at 430,000 mph, with its heat shield at an estimated 1,700 degrees Fahrenheit. Here is what the mission has found so far, and why it keeps going back.

NASA's Juno Measured the Temperature Below Io's Surface for the First Time. The Most Volcanic World in the Solar System Got Stranger.

For more than four decades, everything scientists knew about the heat inside Io came from infrared readings of the moon's surface. Now Juno's Microwave Radiometer has measured the temperature below the crust for the first time, during two close flybys. The results, published in JGR: Planets in July 2026, show heat rising more than 40 degrees Fahrenheit just a few feet down, a surface as smooth and light as volcanic ash, and a technique that could one day help study volcanoes on Earth.

A Wandering Black Hole Tore a Star Apart 30,000 Light-Years From Its Galaxy's Center. It Was the Most Misplaced Star-Killing Event Ever Seen.

Every tidal disruption event astronomers had ever confirmed happened at the center of a galaxy, exactly where supermassive black holes are supposed to live. Then an AI scanning half a million nightly flashes from the Zwicky Transient Facility flagged a flare in a galaxy 750 million light-years away, in a place no black hole was expected: 30,000 light-years from the galaxy's core. Follow-up observations with the SOAR telescope and NASA's Swift confirmed the most misplaced star-killing event ever seen, a wandering supermassive black hole roughly a million times the mass of the Sun.

Physicists Recreated Black Hole Energy Extraction in the Lab Using Synthetic Rotation. A 50-Year-Old Theory Finally Works.

Researchers at CUNY's Advanced Science Research Center demonstrated the Penrose-Zel'dovich process in a laboratory for the first time. Using a ring of electronic resonators that simulate extreme rotation without physically moving, they showed that electromagnetic waves can extract energy from synthetic rotation, confirming a black hole energy theory proposed by Roger Penrose in 1969 and extended by Yakov Zel'dovich in 1971. The findings, published in Nature on July 10, 2026, open new avenues in optics, communications, and quantum science while validating one of the most extreme predictions of general relativity.

The Sun Has a Hidden Switch-Off Signal That Can Predict the Next Solar Cycle Years in Advance

Scientists discovered that the Sun's most extreme space weather does not fade away gradually. It switches off suddenly at a specific point in every solar cycle, and the number of sunspots at that moment predicts how active the next cycle will be up to seven years before it peaks.

Physicists Created a Tiny Universe From 24,000 Atoms and Watched Time Emerge All by Itself

A physicist at the University of Birmingham sealed 24,000 ultracold atoms inside an isolated chamber and watched as time emerged naturally from the system, without any external clock. When the distribution of atoms stopped changing, time effectively stopped. The experiment tests whether time is fundamental or emerges from change.

The Nancy Grace Roman Space Telescope, NASA's next flagship astrophysics observatory, launches August 30 aboard a SpaceX Falcon Heavy. With a field of view 100 times larger than Hubble, a billion-galaxy dark energy survey, and a coronagraph that could pave the way to imaging Earth-like planets, Roman is built to answer questions no existing telescope can touch.

Astronomers Found the First Atmosphere on a Rocky World in the Habitable Zone. A Helium Leak Gave It Away.

For the first time, astronomers have confirmed an atmosphere around a rocky planet orbiting inside another star's habitable zone. LHS 1140 b, 48 light-years away, was found through escaping helium detected by the WINERED spectrograph at Chile's Magellan Observatory. The atmosphere has likely survived for more than 3 billion years, making it the strongest candidate yet for studying potentially habitable worlds beyond our solar system.
