The purported discovery of the chemical phosphine on the "hellscape" that is Venus was probably off the mark, astronomers report.

Clara Sousa-Silva, whose expertise in phosphine as a biosignature gas was key to a recent analysis that may have detected life in the clouds of Venus, has moved to the Center for Astrophysics | Harvard & Smithsonian for the final two years of her fellowship. She discusses the finding and the broader topic of the search for life on other planets.

The Arecibo radio telescope has collapsed but its amazing discoveries will live on.

Growing evidence suggests Venus was a lot like Earth long ago. Researchers say rocks from Venus that collided with the moon could help clear things up.

Some of the oldest terrain on Venus, known as tesserae, hint at past volcanic activity. Is that what made the planet the "hellish" place it is today?

The clouds of Venus may harbour alien life. But where else?
