What the search for aliens can learn from life on Earth
When searching for extraterrestrial life, we have to base our hunt on what we know about life on our own planet. This may seem limiting, but there's a lot we can learn from the astonishingly diverse lifeforms we have here on Earth.
Weaving together a picture of the Cosmos
When we combine data sources, collaborate with each other, and invite artistic perspectives, we can better understand the Universe we live in.

Doing SETI Better by Understanding Ourselves
One of the reasons SETI is hard is that we don’t know exactly what we are looking for, and part of that difficulty is that we still aren’t sure of who we are. An astronomer and an anthropologist team up to explore how cultural myopia shape what we can find in the cosmos.
Let’s be careful about this “SETI” signal
Several readers have contacted me recently about reports that a group of international astronomers have detected a strong signal coming from a distant star that could be a sign of a high-technology civilization. Here’s my reaction: it’s interesting, but it’s definitely not the sign of an alien civilization—at least not yet.
Back on the Rails with OSETI
The Planetary Society sponsored all-sky optical SETI search at Harvard University went off the rails, telescope roof rails that is, but it is back on track and hunting the sky for ET.
