Here are some recent space-related stories of interest.

—SciTechDaily: “NASA Just Found New Signs of Life Inside Venus – Geologic Life, That Is“

Vast, circular features on the surface of Venus may be signs that the planet is still geologically active. That’s according to new research based on data collected over 30 years ago by NASA’s Magellan spacecraft. Unlike Earth, where giant plates of crust shift and recycle through a process called plate tectonics, Venus doesn’t have these moving plates. But its surface is still being reshaped—likely by molten rock rising from deep within the planet.

—USAToday: “NASA ‘Cleanrooms’ Found Crawling with 26 New Bacterial Species“

 A new study reports 26 new bacterial species were found growing inside cleanrooms associated with NASA space missions. Specifically, scientists looked in the cleanrooms used to prepare the Phoenix Mars lander for its launch in August 2007. In the study, scientists analyzed microorganisms growing in the NASA cleanrooms and discovered many of the new species had genes that made them resilient to decontamination and radiation.

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system. Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”)
