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.
Although starlings are a tropical family by origin, Tristram's starling is well adapted to living in a desert environment: it loses relatively little water to evaporation and produces less heat than expected for its base metabolic rate. Its dark plumage may help it survive in the desert winter, when temperatures are low but the Sun's radiation ...
Monoptilon bellioides is a short annual plant; in seasons with very little rainfall, the plant may only grow to 1–2 centimetres (1 ⁄ 2 – 3 ⁄ 4 in), if it ...
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.

The starlings are generally a highly social family. Most species associate in flocks of varying sizes throughout the year. Murmuration is the flocking of starlings, including the swarm behaviour of their large flight formations. [8] These flocks may include other species of starlings and sometimes species from other families.
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
Common starlings take advantage of agricultural fields, livestock facilities, and other human related sources of food and nest sites. Starlings often assault crops such as grapes, olives, and cherries by consuming excessive amounts of crops in large flock sizes and in new grain fields, starlings pull up young plants and eat the seeds.

The W51 nebula in Aquila - one of the largest star factories in the Milky Way (August 25, 2020). Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars. [1]
