Are we alone ?

For thousands of years people have wondered if there is life beyond Earth. This question is yet to be solved. Most planets are inhabitable but Mars can still possibly hold life. Its got the right nutrients in the soil, has water ice, possibly unfrozen water,
and some carbon dioxide frozen into its surface. In 1996 a Martian meteorite was found in Antarctica. Scientist studied this space rock and discovered fossilized bacteria inside the rock. This proved that Mars used to have a watery surface with a good atmosphere to produce life. The meteorite was named Allen Hills  84001. But now Mars has a very low amount of water, and a thin poison filled atmosphere. Life might be somewhere on the surface or underground where there could be more liquid water. But Mars isn't the only place were life might exist. There are many moons that could have more water then Mars. Jupiter's moons Ganymede, and Europa both could have giant underground water oceans. In fact Europa might have more water then Earth. Saturn's moons Titan, Enceladus , and Dione could all support life. Titan has a thick atmosphere and has lakes of liquid methane. Enceladus has crystals of pure water, from erupting water volcanoes, and Dione has markings on it similar to are moon's surface but Dione's marks were probably caused by water flooding the surface and then freezing. These are all good places for life to exist but there could also be life outside are solar system its a big universe.

Jupiter Planet Or Young Star ?

Jupiter is known for its size and weather. Jupiter is the biggest of all the planets in the solar system. Scientists discovered that Jupiter is made  of  mostly hydrogen , and helium gasses. This puzzled scientists, because the sun is also made of these gases. There are few ideas of how this occurred . Some say that it had the right amount gases but it wasn't big enough to cause fusion. So the hydrogen didn't heat up to much. Others think that it didn't have enough hydrogen or helium to burn at all. I believe that when the sun was born the disk that surrounded the sun started getting crushed. This disk had a lot of hydrogen and helium but it wasn't to much so, it started forming a normal planet, but had a very high amount of these gases. So I think that Jupiter is just a normal planet made out of star-like gases. However you can considerate it a star because its a solar system of moons

Dwarf planets

Dwarf planets are objects that are not planets, but at the same time not asteroids, or comets. They are small planet like objects that orbit the sun. Most of them discovered so far. most are near the Kuiper belt. These object include, Pluto, Ceres, Haumea  , Makemake, and Eris. Pluto, discovered in 1930, is the 2nd most massive dwarf planet, and was classified as a planet for 76 years. But in 2006 Pluto was reclassified as a dwarf planet. Pluto has 5 known moons the biggest Charon,  is almost one third of the size of Pluto. Haumea is a very unusual dwarf planet. Haumea has a football type shape. Most likely caused by a impact that sent it flying. It has a 4 hour day. Scientist think that because of this Haumea's surface stretched to the shape that it is today. Makemake was discovered in 2005 and was nick named Easterbunny, because it was discovered right after Easter. Makemake is a reddish brown color, because of the suns radiation . and is covered with ethane ice. Ceres was known since 1801 people back then thought it was a missing planet but was classified as a dwarf planet in 2006. It has an orbit between mars and Jupiter,and is much smaller than are moon. Ceres is considered the biggest asteroid in the asteroid belt. Dwarf planets are found in and out of the solar system. In fact there might be lots that we haven't discovered yet.
