About halley
Science, fresh every day. Independent, sourced, and written to be understood.
halley is an independent science publication. Every day we gather what actually matters in science, space and technology, check it against primary sources, and explain it so anyone can follow. No hype, no clickbait, no invented numbers.
The name comes from Halley's comet, the one that always returns. That is the promise of this site. Science returns every day, and so do we.
Every article cites official sources such as NASA, ESA, IGN and peer reviewed research. When we get something wrong, we correct it and say so.
