![Simulated light curve for a periodic laser beacon at fpulse = 413 Hz at d = 15 pc observed with a Dtel = 1 m telescope at a cadence of 10 µs. The upper panels show a short segment of the noiseless pulse signal (left) and the corresponding signal including the estimated noise contributions (right). The bottom panel shows the integrated folded pulse profile after combining 108 pulses, resulting in an expected SNR of approximately 5.99. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/The-Interstellar-Laser.png?resize=1200%2C716&ssl=1)

The Interstellar Laser Beacons Hypothesis and the Cosmic Lighthouses Project
[astro-ph.IM] In this paper, we argue that in a realistic, resource-limited scenario senders whose intent is to maximize successful communication at the lowest cost will utilize very long-lived, pulsed beacons.

CETI / SETI: The Phonology Of Sperm Whale Coda Vowels
Sperm whales (Physeter macrocephalus) communicate using series of clicks known as codas. In previous research, sperm whale codas have been shown to resemble human vowels acoustically.
