You know, like we all know, rivers come and go, lakes are formed by melting snow and they do eventually dry up. There are places on Mars where there is no liquid water. That’s true for inland lakes and oceanic basins. However, there are lakes that have disappeared, that were dried up years ago. This is not an understatement.
Why have the Lakes on Mars disappeared? Well, there has been much activity in the past, enough to cause drying. Perhaps the greatest event was the Thredosphere. It was like a greenhouse, and when it went, the Earth absorbed it, trapping solar heat, warming the air that rose above it. This warmed the surface of Mars resulting in the creation of the planet’s largest river; the Grand Canyon.
Space travel has always been on the minds of man. Since ancient times it has been speculated that going to space would solve many of mankind’s problems. By creating an independent space station or Colonies to live and study in would relieve the pressure on Earth caused by pollution, lack of oxygen, and lack of resources. Unfortunately as Space tourism interest grows so also do the questions surrounding the validity of these Space claims. Is this really the solution to mankind’s Space woes?
As Space tourism grows so also do the environmental concerns surrounding it. As more people start to explore the possibility of going into space we will undoubtedly find more environmental impacts. But what can we do to stop these environmental impacts from turning into a Space problem?
In a recent discovery, scientists have found 24 super habitable planets that may be even better for life than earth. The discovery of the new planets came from a NASA study called the Habitable worlds survey. The survey looked at all of the stars in the nearby universe to see if any of them had any atmospheres that could support life. It turned out that there are five planets that may even be more suitable than earth for supporting life. The research was led by astronomer Isabel Grosch from the University of Lisbon.
Why do astronomers think there are planets better suited for human life than the earth? The reason is they were not designed for it. For instance, many of these extrasolar planets are very close to their stars. They get tidbits of solar system material that can be caught by solar telescopes and translated into information about the planet’s atmosphere. This can tell astronomers a lot about the nature of the planet. If the planet has a solid interior, liquid oceans, and an atmosphere, then it can have water-life and therefore may be able to support complex life.
The discovery of a rare piece of space rock is exciting. The possibilities are endless when it comes to studying these small and hard space rocks. Although they may resemble diamonds, a rare piece of rare earth has the potential to hold secrets to life on Earth. One day they could hold secrets to finding water on Mars or clues to the construction of other planets. They can also hold clues to the formation of our solar system and perhaps even the future of our galaxy. Studying these rare pieces of rare earth could open up doors to discovering many more like them.
This discovery was made as a result of a rare event. A space rock, which was thought to be a rare grain, was discovered in front of a telescope. It contained oxygen-rich matter which indicated that it was a piece of a rare earth. The scientists used a different telescope to confirm this finding, and from there, were able to learn much about these unique meteorites.
Unlike some rare gemstones, rare pieces of the rare earth will not break the budget as far as cost goes. It’s also relatively common. There are over 10.5% of the earth that is made up of rare minerals. These minerals can be broken down and mixed with other elements to create new compounds.
