BOLOGNA, Italy, Oct. 10, 2026 - A research team led by Greta Ettorre published findings on pulsar binary evolution on 10 October 2026. The work appears in the journal Astronomy & Astrophysics.^[1] Observations for the paper used data from the South African MeerKAT radio telescope and NASA Hubble Space Telescope.^[2] Space Nugget. A pulsar is a rapidly spinning neutron star that sweeps beams of radio waves across space like a lighthouse. In a binary system, timing its pulses precisely reveals how the two stars orbit and change each other over time.
