White dwarf’s eight-minute radio pulse & Euclid opens vast cosmic map - Space News (Nov 12, 2026)

A dead star thousands of light-years away is sending out radio flashes with the regularity of a cosmic clock—and its companion is surprisingly similar to our own Sun. We will explain why that pairing has caught astronomers’ attention. Welcome to The Automated Daily, space news edition. The podcast created by generative AI. I’m TrendTeller, and today is November 12th, 2026. In this edition, we have a vast new view of the universe, fresh confidence in the first black hole image, an asteroid-defense mission reaching its target, new clues from Bennu and another secret military launch.

White dwarf’s eight-minute radio pulse

We begin with a radio signal that repeats roughly every eight minutes. Astronomers have traced it to an unusual binary system containing a white dwarf—the compact remnant of a dead star—and a living star broadly similar to the Sun. The white dwarf appears to rotate extraordinarily quickly, producing radio pulses that become visible for several hours before disappearing as the two stars move through their orbit. This is the first known radio-pulsing white dwarf found with a Sun-like companion. That matters because astronomers have discovered several slow, repeating radio sources in recent years without fully understanding what produces them. This system gives researchers a concrete example that may help explain at least part of that mysterious population. [161][54]

Euclid opens vast cosmic map

Next, the European Space Agency’s Euclid telescope has opened a major new window onto the large-scale universe. Its first substantial public data release contains about thirteen months of observations and captures light from more than a billion objects across a huge section of the sky. Among them are hundreds of millions of galaxies and thousands of candidates for gravitational lenses, where foreground matter bends and magnifies light from more distant objects. Euclid’s larger goal is to build an exceptionally detailed three-dimensional map of the cosmos. By following how galaxies are distributed across space and time, scientists hope to test how dark matter shaped cosmic structure and how dark energy influenced the universe’s expansion. The release is not the finished map, but it gives researchers the foundation—and an immense amount of raw material—for years of discoveries. [87][92]

Black hole image independently confirmed

There is also reassuring news about one of astronomy’s most famous pictures. An independent team has reprocessed the original Event Horizon Telescope observations of M87, the galaxy whose central black hole became the first ever directly imaged. The researchers used a different reconstruction method designed to reduce the influence of calibration errors and subjective processing choices. Their result still produced the same basic ring structure and size. In other words, the glowing ring was not simply an artifact of the original image-making process. The finding strengthens confidence that the picture genuinely represents light bending around the black hole’s shadow. That confidence is important because astronomers use images like this to test gravity under some of the most extreme conditions in the universe. [43][52]

Hera reaches NASA-struck asteroid pair

A second black hole study focused not on a shadow, but on the enormous jets emerging from Centaurus A. These streams of plasma appear brighter along their edges than through their centers, a pattern that has been difficult to explain. New simulations suggest that electrons moving through the jet’s complex magnetic field naturally produce this edge-brightened appearance. The model recreated the pattern seen in observations, offering a more complete picture of how magnetic fields shape the light from powerful cosmic jets. This does not settle every question about how black holes launch and sustain those jets, but it helps connect the underlying plasma behavior with what telescopes actually see. [148]

Bennu organics reveal scattered origins

Closer to home, Europe’s Hera spacecraft has arrived at the Didymos asteroid system and begun its first close survey. Hera is observing Didymos and its smaller moon, Dimorphos, from only a few dozen kilometers away. Dimorphos is the asteroid that NASA’s DART spacecraft deliberately struck in 2022, successfully changing the time it takes to orbit its larger companion. DART showed that a spacecraft could alter an asteroid’s motion. Hera’s job is to examine the result in detail, including the impact site and the physical character of Dimorphos. This follow-up is essential because planetary defense requires more than proving that an impact can work. Scientists need to understand how the outcome changes with an asteroid’s mass, structure and surface. Hera is now beginning that real-world investigation. [117][119]

Second secret Space Force launch

Samples from asteroid Bennu are providing another lesson about the early solar system. Researchers compared the isotope patterns inside an amino acid found in Bennu material with the same molecule in the Murchison meteorite. The two samples showed a similar internal pattern, suggesting related chemistry, but their overall isotope values were notably different. The leading interpretation is that the molecules formed through comparable processes in separate regions of the young solar system. One carbon measurement from Bennu was especially unusual, producing the strongest isotope anomaly yet reported in an organic molecule from an asteroid or meteorite. The result suggests that the chemistry capable of producing ingredients associated with life was not confined to one narrow environment. Instead, similar organic reactions may have unfolded across a wide and varied solar system. [101][147]

Finally, a Falcon 9 rocket has launched another classified payload for the United States Space Force from Vandenberg Space Force Base in California. The mission, known as USSF-627, reached space late Wednesday local time. Officials have not identified the payload or described its intended work. It was the second similarly secret Space Force mission launched from Vandenberg in just six days. With so little public information, it is not possible to assess the spacecraft itself. The wider significance lies in the pace of national-security launches and the increasingly routine use of commercial launch vehicles to place military systems in orbit. Secrecy remains part of that activity, but the launches themselves are becoming much more frequent and operationally familiar. [131]

That is today’s look at the latest developments beyond Earth, from a strange stellar radio beacon to new maps, asteroid investigations and orbital activity.
