- 11883 amateur photo of Orion Nebula remembered●# PPOD : Just three years after Henry Draper captured the first photograph of the Orion Nebula, British amateur astronom
On February 26, 1883, British amateur astronomer Andrew Ainslie Common exposed a photographic plate for 60 minutes, capturing the Orion Nebula just three years after Henry Draper took the first photograph of it. Common's long exposure revealed far more detail than the human eye could see, marking a turning point in astrophotography. The SETI Institute highlighted the anniversary, drawing attention to how an amateur pushed the boundaries of what photography could reveal about the night sky.

A new study proposes searching the Moon's regolith for microscopic technosignatures that could have crossed interstellar space, raising the possibility that fragments of ancient extraterrestrial technology might be preserved in lunar dust. SETI Institute's Dr. Franck Marchis discussed the idea with lead author Dr. Lewis Pinault in a special live conversation, drawing interest from space enthusiasts.

The SETI Institute has announced its largest-ever observing campaign using the Allen Telescope Array, a technosignature survey targeting the anti-solar point, the region of sky directly opposite the Sun. Observing that zone is a strategic choice, as any light or signals reflected from objects there, including potential probes, would be illuminated by the Sun. The project represents a major expansion of the institute's search for evidence of extraterrestrial technology.

A new study co-authored by SETI Institute affiliate Mohit Melwani Daswani addresses a long-standing puzzle about Mars: the planet shows signs of a wet past, yet its carbonate rock record is sparse. The research suggests groundwater may have carried much of that carbonate material underground, meaning future missions could find evidence of Mars' wetter history beneath the surface rather than in exposed rocks.
