The authors proceed to argue that inside Sun-like stars objects that satisfy the above conditions can exist. They also suggest that an indication on the existence of such "nuclear life" could be observed deviations from predictions of models of stellar evolution, such as anomalies in luminosity.
Apelles discusses the transit of Venus but is wrong about the size of the planet relative to the Sun; it is so much smaller than Apelles suggests that it may not even be possible for observers to see it making its transit, meaning that the lack of a definite sighting of the transit does not necessarily prove anything.
The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26]
The faint young Sun paradox or faint young Sun problem describes the apparent contradiction between observations of liquid water early in Earth's history and the astrophysical expectation that the Sun's output would have been only 70 percent as intense during that epoch as it is during the modern epoch.

The sun is acting a little sus Footage of a “massive polar vortex” recorded by NASA’s Solar Dynamics Observatory on Feb. 2, went viral this week, and scientists aren’t exactly sure what ...
The main role of observations and experiments in science, he argued, is in attempts to criticize and refute existing theories. [30] According to Popper, the problem of induction as usually conceived is asking the wrong question: it is asking how to justify theories given they cannot be justified by induction.
A spotlight Sun would also appear at different angles in the sky with respect to a flat ground than it does with respect to a curved ground. Assuming light travels in straight lines, actual measurements of the Sun's angle in the sky from locations very distant from each other are only consistent with a geometry where the Sun is very far away ...
It is a popular misconception that the Sun is red, orange or yellow. In reality, the Sun is white as seen in this solar filter dimmed true-color image. Scientific misconceptions are commonly held beliefs about science that have no basis in actual scientific fact. Scientific misconceptions can also refer to preconceived notions based on ...
