- 1Hubble spots spiral galaxy spinning two ways at once▼NASA's Hubble sees an exotic spiral galaxy spinning two ways at once
NASA's Hubble Space Telescope has observed an exotic spiral galaxy that appears to be rotating in two opposite directions at the same time. The rare finding, reported by NASA and covered by outlets including Mashable, offers astronomers an unusual case study in galactic dynamics and may prompt further research into how such counter-rotating structures form.
- 2Astronomer turns sinking Starlink satellites into planetary barometer●Astronomer watches Starlink satellites sinking to build a 'planetary barometer'
An astronomer is tracking the gradual orbital decay of Starlink satellites to measure density changes in the upper atmosphere, effectively turning the satellite constellation into a global 'planetary barometer'. As satellites sink, the drag they experience reveals how the thin air at their altitude expands and contracts with solar activity. Space scientists are discussing the approach as a clever reuse of existing mega-constellation telemetry for atmospheric research.

The U.S. Federal Communications Commission can single-handedly approve massive spaceflight projects, including large satellite constellations that could fundamentally alter the appearance of the night sky for everyone on Earth. Despite growing public outcry and concern from astronomers, space law experts say the FCC remains effectively the only gatekeeper, with very little other regulatory oversight available to check these approvals.
- 4Astronomers warn proposed 50,000 orbital mirrors would harm sky observation●"'They're saying we want to launch 50,000 mirrors by 2035,' Benvenuti said. 'That would be catastrophic for astronomy, t
Astronomer Benvenuti said plans to launch 50,000 light-reflecting mirrors into orbit by 2035 would be 'catastrophic for astronomy.' The comment came after the FCC reportedly granted approval to Reflect Orbital, a company that intends to bounce sunlight back to Earth as a commercial service. Researchers fear large numbers of bright reflective satellites would interfere with telescope observations and darken the night sky science relies on.
- 5Astronomers say AST SpaceMobile satellites far exceed brightness limits●"Our measurements reveal an average brightness seven times brighter than mitigation targets cited in FCC filings and pea
Astronomers report that measurements of AST SpaceMobile satellites show an average brightness seven times above mitigation targets cited in FCC filings, with peak values more than 200 times brighter than the International Astronomical Union's recommended threshold of magnitude 7. The findings raise concerns as the company prepares to deploy more satellites, with researchers warning of growing interference with ground-based astronomy.
