An astronomer has found a new use for Starlink satellites: tracking how the spacecraft's orbits gradually decay as they sink through the upper atmosphere. By measuring that orbital drag, the researcher aims to turn the satellite constellation into a 'planetary barometer' that reveals density changes in the atmosphere. The idea highlights both the scientific potential and growing concerns around SpaceX's massive satellite fleet.

Spanish media report that astronomers have found evidence of a planet that appears to have formed after its host star died, built from material the star expelled during its death. Outlets including MARCA, ABC and El Debate describe it as a 'second-generation' or 'phoenix planet', a world that rose from the ashes of its dead star. If confirmed, it would be an unusual case of planetary formation around a stellar remnant.

Astronomers report a possible planet in the habitable zone of a star roughly 2,000 degrees hotter than our Sun, a rare find given such stars' intense radiation. If confirmed, it would show planets can survive around very hot stars, prompting discussion about how habitable zones work around extreme hosts.

Saturn reached opposition on Sunday, October 4, meaning the planet is directly opposite the Sun from Earth's perspective. Astronomers note this is when Saturn appears brightest and largest in telescopes, remaining visible all night.

The SETI Institute is explaining how astronomers can tell whether a star has consumed its own planets. Lithium naturally disappears inside stars over time, making it unreliable as evidence, but beryllium lasts far longer. Its presence can therefore indicate that rocky worlds were swallowed, offering a new chemical clue in stellar detective work.
