Astronomers Start Search For Life Beyond Earth - The New York Times - 0 views

  •  
    I'm learning more about extraterrestrial life right now, and in particular what I'm wondering about is: Is there life on Mars, or in space at all? I was researching this question online, and this news item caught my attention because It discusses the search, and research processes of extraterrestrial hunts. "The search for evidence of extraterrestrial intelligence, commonly known by the acronym SETI, began at 3 P.M. today with simultaneous commands to computers and radio receivers here at the world's largest radiotelescope and at another big telescope in the Mojave Desert in California." The quote I chose here is basically saying that the search for extraterrestrial life has began. I think this is surprising because I already know that scientists had already began the "extraterrestrial hunt" but I never or hardly ever hear anything about their progression. After all the hoaxes, the little information dished out about Area 51, I don't know what to believe. I think this issues paranoia and conspiracy among me and countless other people. It really makes me wonder... nothing. It reinforces my stance on trust in the government.

Extraterrestrial life - Wikipedia, the free encyclopedia - 1 views

  • Extraterrestrial life is defined as life which does not originate from planet Earth. The existence of such life is theoretical and all assertions about it remain disputed.

      This is the general definition of what aliens are. They are known as extraterrestrial life that do not live on Earth, but oter space. The last sentence is important because, scientists are still trying to prove the existence of aliens.
  • Suggested locations which might have once developed, or presently continue to host life similar to our own, include the planets Venus[1] and Mars, moons of Jupiter and Saturn (e.g. Europa,[2] Enceladus and Titan) and Gliese 581 c and d, recently discovered to be near Earth-mass extrasolar planets apparently located in their star's habitable zone, and with the potential to have liquid water.[3]
    • Reasat EWSIS
       
      There may be potnetial alien life in various planets, moons, and star (i.e. - Mars, Venus, Jupiter, Europa)
  • Alien life, such as bacteria, has been theorised by scientists such as Carl Sagan to exist in our solar system and quite possibly throughout the universe although no samples have been found.

      Where is the evidence that bacteria exist else where?

  • Scientists are directly searching for evidence of unicellular life within the solar system, carrying out studies on the surface of Mars and examining meteors which have fallen to Earth. A mission is also proposed to Europa, one of Jupiter's moons with a possible liquid water layer under its surface, which might contain life.[19]

  • Independently, in 1996, structures resembling nanobacteria were reportedly discovered in a meteorite, ALH84001, thought to be formed of rock ejected from Mars. This report is also controversial, and scientific debate continues.

      This is important because this is proof that extraterrestrial life existed in outer space, more specifically Mars.

      This isn't proof at all. It says possibly, and it says that there is a lack of evidence.
  • In February 2005, NASA scientists reported that they had found strong evidence of present life on Mars.[21] The two scientists, Carol Stoker and Larry Lemke of NASA's Ames Research Center, based their claims on methane signatures found in Mars' atmosphere resembling the methane production of some forms of primitive life on Earth, as well as on their own study of primitive life near the Rio Tinto river in Spain.
  • Within Islam, the statement of the Qur'an "All praise belongs to God, Lord of all the worlds" indicates multiple universal bodies, and maybe even multiple universes, which may indicate extraterrestrial and even extradimensional life. Surat Al-Jinn also mentioned a statement from a Jinn regarding the current status and ability of his group in the heavens.

      This is interesting because I am a Muslim my self. A lot of things can have different interpretations. I am going to try looking for it in the Qur'an.
  • Europa - Europa may contain liquid water beneath its thick ice layer. It is possible that vents on the bottom of the ocean warm the ice, so liquid could exist beneath the ice layer, perhaps capable of supporting microbes and simple plants, just like in Earth's hydrothermal vents.[2]
    • Reasat EWSIS
  • Mars - Life on Mars has been long speculated. Liquid water is widely thought to have existed on Mars in the past, and there may still be liquid water beneath the surface. Methane was found in the atmosphere of Mars. By July 2008, laboratory tests aboard NASA's Phoenix Mars Lander had identified water in a soil sample. The lander's robotic arm delivered the sample to an instrument which identifies vapors produced by the heating of samples. Recent photographs from the Mars Global Surveyor show evidence of recent (i.e. within 10 years) flows of a liquid on the Red Planet's frigid surface.[34]
  • The other large moons of our system which have been visited appear similarly lifeless, though the interesting geothermic forces observed (Io's volcanism, Europa's ocean, Titan's thick atmosphere) have underscored how broad the range of potentially habitable environments may be.

Vatican Looks to Heavens for Signs of Alien Life - NYTimes.com - 1 views

  • ''Both science and religion posit life as a special outcome of a vast and mostly inhospitable universe,'' he told a news conference Tuesday. ''There is a rich middle ground for dialogue between the practitioners of astrobiology and those who seek to understand the meaning of our existence in a biological universe.''

    I'm learning more about extraterrestrial life right now, and in particular I'm wondering about is: Is there life on Mars, or in space at all? I was researching this question online and this news item caught my attention because It discusses the Vatican's approach on researching Extraterrestrial life. The Vatican is a major congregation of the Catholic church in Rome. ''Both science and religion posit life as a special outcome of a vast and mostly inhospitable universe,'' he told a news conference Tuesday. ''There is a rich middle ground for dialogue between the practitioners of astrobiology and those who seek to understand the meaning of our existence in a biological universe.'' The quote I chose here is basically saying that a common stance is met between scientists that want to research Extraterrestrial-ism and rather more religious people that want to research it. I think this is shocking because... It makes me wonder why would the Vatican of all things want to seek information about Alien Life. I would assume that the Vatican, would oppose any beliefs that life exists outside of earth. The article also mentions that it was appropriate that the Vatican would host such a meeting, this honestly makes me a little paranoid.

Bacteria Could Survive in Martian Soil | Universe Today - 1 views

    I'm learning more about "Life on Mars" right now, and in particular what I'm wondering about is: Is there life on Mars? I was researching this question online, and this blog caught my attention because It said that there is a possibility that bacteria could live on Mars. I thought this discovery was ground breaking, and I thought that nothing could live on Mars. "The question of whether life in the form of bacteria (or something even more exotic!) exists on Mars is hotly debated, and still requires a resolute yes or no. Experiments done right here on Earth that simulate the conditions on Mars and their effects on terrestrial bacteria show that it is entirely possible for certain strains of bacteria to weather the harsh environment of Mars." The quote I chose here is basically saying certain bacteria may be able to survive on Mars, but this is only inferred after a series of experiments, conducted on Earth. I think this is interesting because it makes me wonder if Humans will ever be able to live on Mars, or if anything does exist there, or if anything exists even outside of earth. I first read this and thought, "wow!" this is really amazing. I continued reading and found out that it was not completely true. All of these experiments were conducted on earth, but the test(s) simulated to be like the terrain on Mars. I began wondering why don't they just attempt to place the bacteria, I am sure on less person wouldn't affect the population that badly. I know that is a bit harsh but I don't care.
