- High school student identifies three dwarf galaxies near M101 — Universe Today
Julian Shapiro discovered the galaxies while still in high school during research on star formation rates. The galaxies are now named Shapiro I, II, and III. They sit near the spiral galaxy M101 and show star formation behavior that deviates from typical patterns for dwarf systems. Shapiro is now an astrophysics undergraduate at the University of California, Berkeley, working with Alexei Filippenko. He published the findings in The Astrophysical Journal and received a Davidson Fellowship for the work. Public archival telescope data enabled the discovery without new observations. Shapiro said, “I envision my work serving as inspiration for young people aspiring to pursue research in astrophysics.” Filippenko noted that Shapiro conducted remarkably sophisticated research while still in high school. Dwarf galaxies range from a thousand stars to a few billion and form through material spun out during larger galaxy collisions.

The agencies signed a Memorandum of Understanding titled “Accelerating American Leadership in Space Nuclear Power and Propulsion” on October 8. The agreement covers research, fuel production, testing, launch integration, and operations for fission and radioisotope systems. It takes effect November 1 and supports the Space Reactor-1 Freedom mission planned for 2028. NASA Administrator Jared Isaacman stated the work lays groundwork for fission-powered spacecraft. The Dragonfly mission to Titan will use a Multi-Mission Radioisotope Thermoelectric Generator and 24 heater units under this framework. Lunar Reactor-1 is described as a planned fission surface power system to support future lunar infrastructure. The MOU strengthens existing collaboration on fission and radioisotope power systems.

Observations captured a planet forming from material ejected by a dying star. The system shows the planet assembling from debris in a process that mirrors early solar system conditions. The finding adds to evidence that planetary formation can occur late in a star’s life cycle. Source: vietnam.vn - Dead Soviet satellite breaks apart in orbit again — Space
A defunct Soviet-era satellite fragmented in orbit, adding to a series of similar events. Experts describe the repeated breakups as part of a worrying trend in orbital debris generation. The incident highlights ongoing risks to active spacecraft from legacy hardware. Source: space.com - Far-infrared telescope PRIMA advances toward 2033 launch — Astronomy
NASA selected the PRobe far-Infrared Mission for Astrophysics, or PRIMA, to proceed in development. The mission carries a 1.8-meter mirror and will be the first in a new mission class. It will study the evolution of the universe through far-infrared observations. Source: astronomy.com - Solar Orbiter traces origin of solar wind magnetic switchbacks — ESA Activities
The spacecraft flew through an S-shaped kink in the solar wind’s magnetic field. Fingerprinting of particles inside the switchback allowed researchers to trace its source back to the Sun’s surface. The data reveal new details about how solar magnetism generates these structures. Source: esa.int - ESA and IAU sign agreement to protect dark and quiet skies — ESA Activities
The European Space Agency and the International Astronomical Union’s Centre for the Protection of the Dark and Quiet Sky formalized cooperation at the International Astronautical Congress. The partnership will develop technical solutions to reduce satellite interference with astronomy and stargazing. Growing numbers of satellites have increased both reflected light and radio frequency issues. Source: esa.int - James Webb Space Telescope detects most distant fast radio burst — Phys.org Space

The James Webb Space Telescope examined young star systems in the extreme debris disk phase containing large amounts of warm dust. A team from multiple institutions compiled a sample of 21 such disks using Spitzer and Webb archival data. The systems proved rarer than predicted, appearing around only about one percent of young stars. Source: universetoday.com
Cosmic Spotlight
Julian Shapiro’s discovery of the three Shapiro galaxies stands out because it relied entirely on archival data rather than new telescope time. While still in high school he measured star formation rates in dwarf systems near M101 and identified objects whose behavior challenges standard models of isolated galaxy evolution. The galaxies are now formally named and will be studied further during his undergraduate work at Berkeley. Shapiro noted that public archives offer a critical route for young researchers to make original contributions. His paper in The Astrophysical Journal demonstrates that meaningful cosmological insights remain accessible without major new facilities. The work also highlights how dwarf galaxies serve as building blocks in larger galaxy formation processes.
Cosmic Deep Dive: How Fast Radio Bursts Cross Billions of Light Years
A fast radio burst carries as much energy in a few milliseconds as the Sun emits over several days, yet the signal arrives at Earth as a faint radio whisper after traveling more than ten billion light years. Picture the burst as a lighthouse flash that left its galaxy when the universe was less than a quarter of its current age; by the time the wave reaches us it has spread across a volume larger than the entire Milky Way’s stellar disk stretched end to end a million times. The wave travels through intergalactic plasma that slightly slows lower frequencies, creating a measurable delay that astronomers use like a cosmic ruler to estimate distance. James Webb’s recent detection at redshift 2.148 shows the burst originated when the universe was roughly three billion years old, a period when galaxy formation was still ramping up. We can record the arrival time, polarization, and dispersion measure with increasing precision, but the physical process that releases such concentrated energy in a millisecond remains unknown. No model yet explains why some bursts repeat while others appear only once, or why their host galaxies range from quiet ellipticals to vigorously star-forming dwarfs.
