The Cookbook Of Life

One of humanity’s most profound questions is whether life exists beyond Earth — and if so, what forms it might take. For decades, the search for life has often focused on finding conditions similar to early Earth, assuming life must follow a carbon-based blueprint.

Red Planet, Blue Past

What if billions of years ago, the Red Planet had rain, snow, and even rivers that carved out landscapes much like those we see on Earth?

Tiny Asteroids, Big Threats

When we think about asteroids that could threaten Earth, we often imagine massive, city-sized rocks hurtling through space. But what if the real danger comes from much smaller, barely detectable ones?

Cosmic Cataclysms

Stunning stellar explosions occur every second across the cosmos – some observable, most too distant to ever know, all of them fleeting, lasting from seconds to tens of thousands of years. In the age of the universe, these events are brief flashes in the passing of time; for stars it is them gasping for life or their explosive end; in galaxies, local regions can be altered as a consequence. From the perspective of humankind, these transient events contain many undiscovered truths of our univers…

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?

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…
