What happened

Space telescopes are now overwhelmed by satellite trails Lisa Lock Scientific Editor Andrew Zinin Lead Editor Unfortunately, there's more bad news to report on the clear skies front.

Why it matters

A new paper, available on the arXiv preprint server from researchers at NASA's Ames Research Center, reports that 73.3% of images the agency's new SPHEREx space telescope collected between May and September of last year were contaminated by at least one…

Common ground

Unfortunately, this doesn't come as a surprise.

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Fear: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
