Discovery connects astronomy and alchemy #

An intriguing figure from the Renaissance period is the link between astronomy and alchemy, as revealed in a recent discovery. Danish astronomer Tycho Brahe, known for his contributions to understanding the heavens, also conducted secretive alchemical work in the basement of his castle. Analysis of glass shards from his alchemy lab unveiled ingredients used in his mysterious concoctions, including tungsten. This finding sheds light on the intersection of astronomy and alchemy during that time.

Root cause of spacecraft issues identified #

NASA and Boeing are closing in on the “root cause” of the problems experienced by Boeing’s Starliner spacecraft during its mission. Issues such as helium leaks and thruster problems have been the focus of ground tests to replicate these anomalies. Meanwhile, SpaceX has gained approval to continue launches using its Falcon 9 rocket. Once the ongoing Starliner mission concludes, SpaceX will transport astronauts for NASA’s Crew-9 mission to the International Space Station.

Unusual oxygen discovery on seabed piques interest #

Marine scientists have made a remarkable discovery on the seabed: a type of oxygen produced without photosynthesis. This finding, more than 13,000 feet below the ocean’s surface, challenges previous knowledge about oxygen production in such environments. Researchers believe that this “dark” oxygen may be generated by metallic nodules resembling “geobatteries.” Further exploration and analysis of this phenomenon could provide valuable insights into the origins of life.

Boat strikes pose risks to endangered sharks #

Shocking footage captured by a camera attached to an endangered basking shark highlights the dangers posed by boat strikes. The video shows the moment a boat collides with the shark, leaving visible marks on its skin. The incident emphasizes the need for protection of endangered sea creatures like the basking shark. Additionally, cocaine has been detected in free-ranging sharks off the coast of Brazil, marking the first time this drug has been found in sharks in their natural habitat.

Clues of past life on Mars discovered #

The Perseverance rover has uncovered potential evidence that suggests Mars might have supported microbial life in the past. Analysis of a rock known as Cheyava Falls has revealed chemical signatures and structures that could have been formed by ancient life when water was present on the red planet. Similar features on Earth often indicate the existence of fossilized microbes in subsurface environments. This finding brings scientists closer to understanding the potential for past life on Mars.

Unusual phenomena: iron-tipped teeth, glowing images, and blushing chickens #

New research reveals that Komodo dragons possess iron-tipped teeth that aid in prey consumption. The iron stains the serrated edges of their teeth and assists in tearing apart food. In celebration of its 25th anniversary, the Chandra X-ray Observatory has unveiled 25 captivating images of the cosmos, which may be its last due to potential NASA budget cuts. Besides humans, domestic hens have been observed blushing—a pink-tinged response signifying fear or excitement.
