The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens.

This is a list of active, dormant, and extinct volcanoes located beyond planet Earth. They may be designated mons (mountain), patera (an irregular crater) or tholus (small mountain or hill) in accordance with the International Astronomical Union 's rules for planetary nomenclature .
The lava cactus is endemic to the Galápagos, where it is found on Fernandina, Genovesa, Isabela, Pinta, Santa Cruz, and Santiago, [12] as well as some smaller islands, [2] including Bartolomé. [1] It grows on barren lava flows, both pāhoehoe and ʻaʻā. [2] It is one of the first species to grow on new lava flows. [1]
Li said the new findings reveal over 1 billion years of volcanic eruptions on the lunar far side. One piece of volcanic rock dated back 4.2 billion years.
The Dawn space probe found possible evidence of past water flow on the asteroid Vesta, [93] leading to speculation of underground reservoirs of water-ice. [ 94 ] Astronomers speculate that Venus had liquid water and perhaps oceans in its very early history. [ 95 ]
When Mount Vesuvius erupted, plants in the village were preserved; now, they retell the village’s disastrous day, researchers say. Volcano eruptions buried this Italian village long before ...
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
