A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering both star-forming regions and the remains of ancient stellar explosions. Scientists can now better distinguish where stars are being born versus where they’ve met dramatic ends. The discovery opens powerful new ways to study the life cycle of stars and the shape of our galaxy.

$99,000 smart observatory captures the cosmos with Canon optics
One would think that a US$99,000 telescope requires specialist training and a thick instruction manual. But the new Hyperia from French company Vaonis flips that assumption on its head. It’s powerful enough for professional observatories yet runs entirely from a simple smartphone app.
Vaonis has been bringing astrophotography to the masses for years now. The company has stripped away the complexity, allowing anyone to snap spectacular images of galaxies and nebulae hundreds of light-years away without wrestling with multi-component setups requiring serious technical chops – all wrapped in Vaonis’s trademark minimalist design.
The Hyperia started as a custom build for the Palais de la Découverte in Paris, which needed a next-gen digital observatory. After wrapping up the installation, Vaonis saw the bigger picture and decided to sell the system commercially.
A white dwarf’s cosmic feeding frenzy revealed by NASA
Using NASA’s IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star’s magnetic field and glowing in intense X-rays. These features are far too small to image directly, but X-ray polarization allowed scientists to map them with surprising precision. The results open new doors for understanding extreme binary star systems.
Scientists have, for the first time, used NASA’s IXPE (Imaging X-ray Polarization Explorer) to investigate a white dwarf star. The mission’s ability to measure the polarization of X-rays allowed astronomers to closely examine EX Hydrae, a type of system known as an intermediate polar. These observations provided new insight into the physical structure and behavior of powerful binary star systems.
During 2024, IXPE spent nearly a full week observing EX Hydrae. This white dwarf system lies about 200 light-years from Earth in the constellation Hydra. The results of the study were published in the Astrophysical Journal. Researchers from the Massachusetts Institute of Technology in Cambridge led the work, with additional contributors from the University of Iowa, East Tennessee State University, the University of Liége, and Embry Riddle Aeronautical University.
The shape of things to come: How spheroid geometry guides multicellular orbiting and invasion
As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues. There are no anatomical molds shaped like lungs, livers or other tissues for cells to grow into. Rather, these structures form through the coordinated activity of different types of cells as they move and multiply.
No one is sure exactly how cells manage this collective construction of complex tissue, but a study by Brown University engineers could offer some new insights.
The study, published in Nature Physics, looked at how human epithelial cells behave as spherical aggregates confined inside a collagen matrix. The research revealed surprising ways in which cell clusters first rotate collectively within the confined space, then eventually reconfigure their surroundings to allow individual cells to venture out of the sphere.
Reentry and disintegration dynamics of space debris tracked using seismic data
Therefore, there is a pressing need to develop tools that can be used to determine the trajectory, size, nature, and potential impact locations of reentering debris in near real time. This is a critical step toward mobilizing appropriate response operations (7). In this work, we have demonstrated that open-source seismic data are capable of fulfilling this requirement.
Past work has demonstrated the sensitivity of seismometers to reentry-generated shockwaves and explosions of natural meteoroids [for example, (8–10)]. However, the trajectories, speeds, and fragmentation chains of artificial spacecraft falling from orbit are distinct from those of natural objects entering from beyond the Earth‒Moon system. This means that the patterns of debris fallout that artificial spacecraft produce are also potentially more complex; for example, some components such as fuel tanks are structurally reinforced and hence more likely to survive and impact the ground, whereas others (such as solar panels) are deliberately designed to demise during reentry. Therefore, techniques used for natural objects require modification.
Hubble Images of 3I/ATLAS During Its Rare Alignment with the Sun-Earth Axis on January 22, 2026
Good news. The rare cosmic alignment between the interstellar visitor 3I/ATLAS, the Earth and the Sun, was captured by the Hubble Space Telescope on January 22, 2026.
A new set of six 170 second exposures, taken by the Hubble Space Telescope between 13:10:30 and 13:43:33 UTC on January 22, 2026, were just posted here. The exposures display brightness maps of the glowing halo surrounding 3I/ATLAS. The glow is elongated by about 100,000 kilometers in the direction of the Sun, a length scale which is about ten times larger than the Earth’s diameter.
In a new paper that I published with Mauro Barbieri here, we alerted astronomers to this “full Moon phase” of 3I/ATLAS when observers from Earth will see it from the direction of the Sun to within an extremely small misalignment angle of just 0.012 radians. This rare alignment resulted in a brightness surge whose magnitude and growth rate are dictated by the composition and structure of the particles shed by jets of 3I/ATLAS. No new data other than the Hubble images was made public as of yet.
