Blue Eye Pulsar radio comeback
Our first story centers on that mysterious cosmic lighthouse: the so‑called Blue Eye Pulsar. Astronomers have just reported renewed radio signals from this extremely rare object after decades of near silence, making it one of the most intriguing neutron stars in the sky. A pulsar is the collapsed core of a massive star that exploded, spinning rapidly and sweeping beams of radiation across space like a lighthouse. The Blue Eye Pulsar sits at the center of a nebula and was already unusual because of its striking X‑ray and optical appearance, but it had stubbornly refused to shine in radio, which is how most pulsars were originally found. Now, Chinese scientists, working with data from large radio facilities and reported by the National Astronomical Observatories of the Chinese Academy of Sciences, have finally detected radio pulses from this object, confirming it as a true pulsar and not just an X‑ray oddity. Space.com highlights that this is the first time astronomers can study its radio waves, X‑rays, and magnetic field structure together, turning the Blue Eye into a kind of laboratory for testing how extreme magnetic fields distort radiation and how pulsars can switch between different emission states.
What makes this discovery so compelling is the timing and the transformation. For decades, the Blu

Today's topics:
Blue Eye Pulsar radio comeback - Astronomers have finally detected radio signals from the rare 'Blue Eye Pulsar' after decades of silence, opening a new window on neutron star behavior and extreme magnetic fields. Keywords: Blue Eye Pulsar, radio signals, neutron stars, Chinese astronomers, Space.com.
Featherweight super-puff exoplanets - A team has confirmed two giant, 'cotton-candy' super-puff planets with densities lighter than candy, challenging current models of how gas giants form and hold on to their atmospheres. Keywords: super-puff planets, exoplanets, low density, TOI-791, TESS.
Starlink launch with chip labs - SpaceX launched another batch of Starlink satellites from Florida, sharing the ride with experimental semiconductor manufacturing pods that briefly experienced microgravity before returning to Earth. Keywords: Starlink 10-50, Falcon 9, Besxar Space Industries, semiconductor test bed, space manufacturing.
China expands commercial constellations - China used Long March rockets to add new satellites to its commercial low-Earth orbit constellations, strengthening its role in global broadband and remote sensing markets. Keywords: Long March-6, Long March-8A, Spacesail Constellation, Chinese commercial satellites.
Hubble’s Fourth of July star cluster - NASA’s Hubble Space Telescope released a patriotic 'red, white, and blue' image of one of the Milky Way’s oldest star clusters, offering clues to how early stellar explosions seeded the galaxy with elements for planets and life. Keywords: Hubble, NGC 6426, globular cluster, Milky Way halo, chemical evolution.
