Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
Moving Earth is a theoretical astroengineering concept that involves physically shifting Earth farther away from the Sun to protect the planet's biosphere from rising temperatures. These expected temperature increases derive from long-term impacts of the greenhouse effect combined with the Sun's nuclear fusion process and steadily increasing ...
The mean time for the Sun to collide with another star in the solar neighborhood is approximately 30 trillion (3 × 10 13) years, which is much longer than the estimated age of the Universe, at approximately 13.8 billion years. This can be taken as an indication of the low likelihood of such an event occurring during the lifetime of the Earth. [30]
The SpaceX and Tesla pioneer has warned that travel to other planets was necessary as Earth would be engulfed by the Sun. Elon Musk says humans must leave Earth "because sun will engulf our planet ...
The savannah hypothesis (or savanna hypothesis) is a hypothesis that human bipedalism evolved as a direct result of human ancestors' transition from an arboreal lifestyle to one on the savannas. According to the hypothesis, hominins left the woodlands that had previously been their natural habitat millions of years ago and adapted to their new ...
Ecophysiology (from Greek οἶκος, oikos, "house(hold)"; φύσις, physis, "nature, origin"; and -λογία, -logia), environmental physiology or physiological ecology is a biological discipline that studies the response of an organism's physiology to environmental conditions.
The Sun is said to be extremely noisy, but we can’t hear it since sound doesn’t travel through space. Scientists at the University of Sheffield decided to use vibrations within our star's ...
It can be compared to the tail of a comet (however, a comet's tail does not stretch behind it as it moves; it is always pointing away from the Sun). The tail is a region where the Sun's solar wind slows down and ultimately escapes the heliosphere, slowly evaporating because of charge exchange. [42]
