Space Science Notes study notes for college and university students: the study of stars, planets, and other objects in space. Astronomers want to understand the universe and our planet’s.
Space company Orbital Assembly has presented a project for the Voyager station. It is expected that it will become the first orbital station with artificial gravity. What is Voyager? Voyager is a huge ring, 200 meters in diameter, that constantly rotates rapidly to create an artificial force of gravity comparable to that of the moon. … Read more
We’ve already discussed that, for example, it won’t be very good on Mars without a spacesuit. On “hospitable” Venus, too. Remember how Arnie looked when he found himself in a vacuum on the red planet for a couple of minutes in Total Recall? He definitely didn’t like it, and despite the fact that it’s a … Read more
The Universe for a physicist is not just a boundless space filled with galaxies and stars. It is a dynamic and constantly evolving entity that includes absolutely everything. Time, space, energy, matter, the laws of physics, and even the very possibility of existence. From the birth of the first stars and galaxies to the formation of … Read more
Even millions of light years away, stars shine in the night sky because they are incredibly hot. Planets, in turn, tend to be much colder than these other stellar objects. In between, there are brown dwarfs, which are often a major astronomical enigma. More massive than planets , but less than stars, these stars do not fit perfectly into … Read more
If the emergence of animal life is not a simple matter? What if the origin of multicellular organisms requires a highly improbable combination of geological and astronomical coincidences? These questions gave rise to the so-called rare earth hypothesis. Read extensively in the lines below. Are we alone in the universe or not? The Rare Earth hypothesis was proposed … Read more
The solar ecosphere is the space occupied by the solar system whose temperature is favorable for the development of carbon combinations and serves as the basis for life forms on the planets . The planets included within the ecosphere have temperatures no higher than 80 °C and no lower than –70 °C. Features The ecosphere ranges from a minimum distance of 90 million … Read more
