People from cultures around the world are watching Mars since ancient times. Because it went out red, it was always called red plans.
The English name for the planet comes from the Romans, who call it Their god of war Because its color reminds them of blood. In fact, the red color of Mars came from Iron oxide of rocks and dust Cover over it.
Your blood is also red Due to steel and oxygen mixture of a molecule called hemoglobin. So in a way, the old connection between planets Mars and blood is not perfectly wrong. Bet, which is a common form of iron oxide to be found on earth, often with red color.
In my current research over roundI see different types of signals from planets ahead of the ground. Many interesting physics go to how researchers see colors of planets and stars through different types of telescopes.
Observing Mars with Protes
If you look closely at the Mars photos taken by the rovers above, you’ll see that most of the planet is not red, but more colorful.
Probes sent from WORLD Took pictures showing rocks with colored color. A 1976 Picture from Viking LanderThe first spacecraft of the land of Mars, showed Gartian ground covered with a layer of rusty orange dust.
Not everyone within Mars has the same color. To the poles, it Ice Caps appear to be white. These ice caps contain water, such as ice we usually see in the world, but these ice caps are also covered with a layer of Frozen Carbon Dioxide – dry ice.
This layer of dry ice It can be prompted immediately when sunshine shines over it and grow again when it’s dark. This process causes white ice caps to grow and decrease size depending on martian times.
More than visible light
Mars also handed the lights on the colors you couldn’t see in your eyes but scientists can measure special cameras on the telescope.
The light itself can be considered not only as a wave but as well as a Stream to particles called photons. The amount of energy carried by each photon is related to its color. For example, blue and violet photons have more energy than orange and red photons.
Ultraviolet photon There are more energy than the photons you see in your eyes. These photons appear in direct sunlight, and because they have many energy, they can destroy your body cells. you can use sunscreen to protect yourself from them.
Infrared photons There’s less energy than the photons you see in your eyes, and you don’t need any special protection from them. This is how few kinds of goggles at night work: they can see the light of infrared spectrum as well as visible color. Scientists can take pictures of Mars at the infrared spectrum with special cameras working nearly like Goggors at night for telescope.
Infrared photo colors are never what infrared light looks like, because you can’t see the colors in your eyes. They are called “false colors,” and researchers can easily add a photo to see more easily.
If you compare the found picture of the color and the infrared picture, you can see some of the same parts – and the ice caps appear in the same sets of colors.
NASA’s Maven Spacecraftlaunched in 2013, still taken Pictures with ultraviolet lightthat scientists have been given different views of the Mars and around it.
Every new type of picture tells scientists about the Martian field. They hope to use these details to answer the questions about how Mars formed, how long it will last Active volcanoWHERE its atmosphere from and if it is liquid water above it.
Astronomers always looking for new ways to get pictures of the telescope outside of Regularly visible spectrum. They can still create images using use radio wavesMicrowaves, X-ray and gamma rays. Every part of the spectrum they can use to view something in space represents new information they can learn from.
Although people looked at Mars since ancient times, we learned more about the fascinating neighbor.
