Comet C/2025 F2 (Swan): An Unpredictable Journey

This spring, skywatchers have been treated to the captivating and unpredictable display of a new comet, called C/2025 F2 (SWAN). Discovered in late March 2025 through data from the SWAN instrument aboard NASA and ESA’s Solar and Heliospheric Observatory, this long-period comet is making its journey to the inner solar system from the distant Oort Cloud. Amidst the excitement of a new celestial visitor, observers have taken note of its unpredictable behavior.

Intelligent Life: A Natural Outcome Of Planetary Evolution?

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by postdoctoral researcher and geobiologist Dr. Daniel Mills from the University of Munich challenges that idea, and the implications are game-changing for the search for extraterrestrial intelligence.

When we imagine the search for life on Mars, we often picture high-tech rovers scanning dusty landscapes or orbiters analyzing strange rock formations from above. But what if the key to discovering ancient life isn’t in the vast Martian deserts – what if it’s hidden inside crystals?

Biosignatures On K2-18 B?

Madhusudhan et al. just reported ~3 sigma detection of dimethyl sulfide (DMS) or dimethyl disulfide (DMDS) in the atmosphere of K2-18 b in the Astrophysical Journal Letters. The claim is intriguing, as these gases can be associated with biological activity. On the other hand, the signal is modest, ambiguous, and potentially explainable as the result of noise or systematic error. Moreover, abiotic sources for these compounds do exist, and even if they are low-yield and short-lived, they cannot y…

How Ancient Martian Rocks May Have Helped Water Flow On Its Surface

A new hypothesis from SETI Institute scientist Dr. Janice Bishop and Dr. Melissa Lane from Fibernetics in Pennsylvania could explain how early Mars may have had water on its surface, similar to Earth, even though today its atmosphere is too thin to support liquid water. Bishop and Lane suggest underground water could have formed clays and carbonates billions of years ago – either through subsurface reactions with rocks or precipitation from saturated pore waters. Later, salty, acidic water at t…

Ever Wonder Why Some Meteor Showers Are So Unpredictable?

April 16, 2025, Mountain View, CA -- Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? In a paper published online in the journal Icarus this week, two SETI Institute researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.

What If We Find Nothing In Our Search For Life Beyond Earth?

April 7, 2025, Mountain View, CA -- What if we spend decades building advanced telescopes to search for life on other planets and come up empty-handed? A recent study led by ETH Zurich researchers including corresponding author and SETI Institute affiliate, Dr. Daniel Angerhausen, tackled this question, exploring what we can learn about life in the universe—even if we don't detect signs of life or habitability. Using advanced statistical modeling, the research team sought to explore how many ex…
