We can look for it by using these tecniqes.
•Seeing it in rocks (meteorites)
•Seeing it gravitationally
•Seeing it spectroscopically (remote sensing)
•Seeing morphological features of it (remote sensing)
•Seeing it (remote sensing)
By sending a probe to other planets we get amazing pictures how what they look like close up. Other sensors on the probe can find out about the magnetic field and the surface temperature, and chemicals in the atmosphere, and find out details of the moons and rings of the outer planets.
Look at some pictures of the four Galilean moons. There's a black one, a red one, a yellow one and a sort of white one.
Earth is dangerous. However there are many factors which need to be answered and lets look at our solar system first. For Humans the following factors need to be taken into account to survive without any protection Lack of Oxygen- all other planets and moons lack oxygen Lack of liquid Water- all other terrestrial planets lack liquid water (currently) however it may be present on some moons high or low temperatures (down to 3 degrees Kelvin and upwards to 700) high radiation and lack of a magnetic sphere poisonous or corrosive atmospheres Other solar systems which meet human habitation requirements might have toxic plants or biota.
Yes, space probes have studied the atmospheres of planets and moons in our solar system. For example, the Cassini mission observed the atmospheres of Saturn and its moons, while the Juno mission focused on studying Jupiter's atmosphere. These observations help scientists better understand the composition, structure, and dynamics of these planetary atmospheres.
the real question is, what DON'T they look at? they look at stars, asteroids, galaxies, potential planets that could hold life, moons planets, clouds of alcohol, black holes, and much more. they try to find missing matter, dark matter, etc.
Liquid water. All else is incidental.
yes look at mars there are many trenches from erosion
collect rocks or look at all the other planets and moons around Jupiter
I think when the telescope was invented, I think people use it to look at other planets. Even moons.
because they reflect sunlight
Scientists often look for the molecule water when investigating the possibility of life on other planets. Water is essential for all known forms of life and its presence can indicate the potential for habitability on other planets.
If you look at it in a planetary perspective they are called moons. But if you look at it in a solar system perspective they are called planets, dwarf planets and asteroids. If you look at it at a galaxy size they are called Suns and Stars.
Liquid water is an indicator that there is probably life present.
Well, dwarf planets are much much smaller than planets and some people may confuse some of Jupiter's largest moons as dwarf planets but because some people may look at the moons and confuse them with dwarf planets (i know someone who dose) !!
Scientists look for molecules such as water, methane, and organic compounds like amino acids or nucleotides when investigating the possibility of life on other planets. These molecules are considered essential for life as we know it.
