Methane Discovery on Mars

Scientists have recently found methane in Mars' atmosphere, increasing the chance of life there.the origin of the methane might have come from past subsurface microorganisms, geological activity or comets attacking Mars as scientists assume. unfortunately, Scientists don't know exactly how long the substance has been there. Professors are getting ready to explore and examine deeper if life is available on Mars. Methane is the central ingredient for natural gas. It consists of four atoms of hydrogen bound to one carbon atom. A NASA team located 3 spectral features of methane named absorption lines with the help of spectrometers on telescopes. That discovery obviously proved the mars owned methane. NASA's latest Mars' assignment had received soil samples announcing that mars is capable of supporting human life. Other evidence including ice, also proved that life on mars is possible.

Elcertomagnetic Spectrum

Last week, our science class worked on the electromagnetic spectrum. The electromagnetic spectrum is the complete range of electromagnetic waves placed in order of increasing frequency. The spectrum is made up of radio waves, infrared rays, visible light ultraviolet rays, X-rays, and gamma rays classified in the correct order. We have studied all of the types of rays in our lab tables. Radio waves have the longest wavelengths and the lowest frequencies. Infrared rays, which I studied deeper into, have wavelengths shorter than radio waves. Visible light, which we also did a whole lab of, are the only electromagnetic waves you can see with the naked eye. Ultraviolet rays, have wavelengths just shorter that visible light. X- rays, often used from medical vision of human bones, has wavelengths just shorter than Ultraviolet waves. Finally, Gamma rays are the ones that have the shortest wavelengths and the highest frequencies. All the waves in the electromagnetic spectrum are used for many common purposes. To sum up, the electromagnetic spectrum has many aspects included in it, but can be a very interesting topic to study.

Barack Obama Inauguration

This past Tuesday, the first African American president, Barack Obama, was inaugurated. As 1.5 million people crowded around the National Mall Obama swore to oath. "Today I say to you that the challenges we face are real," Obama said in his inaugural address. "They are serious, and they are many. They will not be met easily or in a short span of time. But know this, America: They will be met." He also mentioned economic problems and how we will overcome them, the Muslim world issues and how we will leave Iraq in peace. In addition he also threatened terrorists. As quoted "You cannot outlast us, and we will defeat you." Leaders around the globe congratulated him in his victory such as French President Nicolas Sarkozy. Finally, change we can believe in. I believe, Barack Obama will truly change this nation and any issue we face now will be resolved. Yes we can.
