    Nature Astronomy editorial: "With threats to #astronomy from all directions, we must consider the true value of astronomy. Astronomy educates the public; astronomy trains a data- and technology-centred workforce; astronomy supports other sciences, providing a laboratory to physicists and a chance to investigate other worlds to biologists and geologists; astronomy inspires curiosity and art and interest in science; astronomy involves big projects; astronomy gets people out into nature; astronomy is an international field, with global collegiality; astronomy adds to the repository of human knowledge. These are the aspects of astronomy that we should be regularly reminding our elected representatives about."

    On the front page of spaceweather.com today: "Last month, astronomer Gerald Rhemann attempted to photograph Comet Wierzchoś (C/2024 E1) during its closest approach to Earth. The comet was outnumbered 10:1 by #satellites.

    "It's about to worsen. Right now, Earth is surrounded by almost 10,000 Starlinks with future plans calling for 42,000. Amazon’s Project Kuiper has begun launching its own planned 3,200-satellite broadband fleet, while China is building two more megaconstellations: Guowang (13,000 satellites) and "Qianfan" ("Thousand Sails", 15,000-plus). Together, they could eventually rival Starlink or even surpass it."
