3+ day, 17+ hour ago   (132+ words) The James Webb Space Telescope (JWST) has opened up many wonders of the cosmos to scientists since it began its science operations a few years ago. But one thing that it hasn’t done is find an “exomoon”. These, as yet…...

5+ day, 12+ hour ago   (766+ words) Earth's surface water puts the planet into its own, privileged category among the Solar System's bodies. Nowhere else is it found, and this water allowed life to appear and fluorish. Nobody argues that, but what's still up for debate is…...

1+ week, 5+ day ago   (188+ words) Inorganic compounds, such as iron chloride or sulfur compounds have been the favorite of modelers of Venus’ atmosphere for decades. However, they face a major reality check in light of this new evidence. To meet the necessary absorption numbers, they…...

1+ week, 6+ day ago   (165+ words) But, if one of the Sun-like stars in the binary (and to be clear, they could both be Sun-like) has an exoplanet, that planet would cause a periodic shift in the relative separation. Which is exactly what SHERA is designed…...

2+ week, 3+ day ago   (953+ words) There's some misunderstanding among the public at large in regards to what a scientific theory is. They're statements about nature based on logic, evidence, and observation. But they're not papal pronouncements about reality that can never be challenged, lest the…...

3+ week, 3+ day ago   (563+ words) Over the last three decades, computer models of forming planetary systems have gone from being fairly crude replications to sophisticated simulations using thousands of different initial starting points. A paper presented at the recent Origins 2026 conference in Paris detailing recent…...

3+ week, 3+ day ago   (496+ words) Stars are a critical piece of the larger cosmos. They're engines of nucleosynthesis, forging the elements—and the planets—that make life possible. Their feedback regulates physics on a galactic scale, they can serve as standard candles that let us…...

4+ week, 2+ day ago   (331+ words) Some signs of an alien civilization are easier to spot than signs of life itself. On technosignatures, from CFCs and industrial gases to the pandemic dip in pollution, and why Earth's most detectable moment might be right now....

4+ week, 2+ day ago   (41+ words) A single pixel of light holds astonishing detail. How ocean glint, rotational mapping, and the vegetation red edge let us read a distant planet's oceans, continents, and even forests, all without ever resolving it as more than a point....

3+ week, 5+ day ago   (158+ words) For decades, scientists have theorized that young protostar jets are shaped and driven by complex, twisted magnetic fields. But they couldn't detect them. Now, thanks to ALMA, they've found them around a young binary protostar....
