NASA finds new moon on Neptune

This diagram provided by NASA shows the orbits of several moons located close to the planet Neptune. NASA announced the discovery of Neptune’s 14th moon Monday, July 15, 2013.

WASHINGTON—A tiny new moon has been spotted circling Neptune— the 14th known to be orbiting the faraway planet, the US space agency said on Monday.

The moon is the smallest ever glimpsed around Neptune and measures just about 12 miles (19 kilometers) across, based on observations from the Hubble Space telescope, NASA said.

Neptune is the farthest planet from the Sun, and NASA said the moon, named S/2004 N1, is about 100 million times fainter than the dimmest star that can be seen with the naked eye.

Astronomers found the moon by tracking a white dot that appeared repeatedly in more than 150 photos taken by Hubble from 2004 to 2009.

Mark Showalter of the SETI Institute in Mountain View, California, found the moon July 1 while studying the faint arcs around Neptune, NASA said.

“The moons and arcs orbit very quickly, so we had to devise a way to follow their motion in order to bring out the details of the system,” he said.

“It’s the same reason a sports photographer tracks a running athlete—the athlete stays in focus, but the background blurs.”

The moon is believed to circle Neptune once every 23 hours.

    discoveries in science needs revision of textbooks. during my primary years, if a pupil could not answer that Pluto is the smallest planet in the Solar System, the poor kid is whipped and verbally abused and called bobo.
    today, Pluto, was rendered not a planet owing to changes in definition what a planet is.
    naawa ako sa classmate ko na nabugbog ng insulto ng teacher ko dahil hindi masabi ang nth planet kuno.

      Your teacher is psychotic! I sure hope he/she is no longer teaching or has learned better ways to teach.

      • batangpaslit

        Mux…..there are terror teachers in a literal sense. Rather than impart learning to their students, they scare off young minds to love schooling.
        I visited the old homeland during the midterm Election. I did meet my elementary teachers who were kind to their pupils. I did relate the story that you responded. Ms Anne, my kind teacher agrees with your point of view. She expressed it in different terms her disgust to the teacher I described in this post.
        You must be an educator, Mux? Gleaned from your one liner riposte, it is clear you know your beans.

      • Mux

        Actually, I did teach for one year but that was a long time ago. Also, one does not need to be an educator to know that scaring students is counter productive. It doesn’t work. I did have an Art teacher in grade school who would literally tear our drawings in front of us if she didn’t like it. That’s why upto know, my drawings are the worst because I never learned how to draw properly. I don’t know how I passed.

        indeed, teaching is a gift.
        talents are innate, skills can be acquired.
        my younger son, did not earn an academic degree in music. he did take formal lessons in piano. today, he composes music and plays various musical instruments. he has an innate talent in music.
        while my elder son was trained in furniture making. after couple of years, he was promoted and was sent offshore to train the subcontractors in Mexico, Indonesia, and in Lithonia. he acquired the skills in the course of his job.
        good teachers leave lasting memory to their students that they mentored.
        everytime I return home, as a gesture of appreciation, I always treat my former teachers I can find to posh restaurants and just reminisce the days how I was mentored by them.

      • Mux

        That’s very nice of you! Shows your appreciation and I would bet that your former teachers appreciate that too. :)

      • Mux

        You sound like my oldest daughter. If ever she gets lost, we know to
        find her in either National Bookstore or Powerbooks. My younger daughter
        is more difficult, she likes clothes and there are usually many
        clothing stores in malls. :)

      • batangpaslit

        so, you have two daughters that drives you, eh?
        the elder one drives you to open your Dictionary; while your younger one drives you an ATM machine?

      • Mux

        Right!! :)

  • Mux

    Duran Duran will like this. They found a New Moon on Monday. :)

    Though this is interesting news, why is it in the Business section?

    NASA finds new moon. But here in the Philippines we found crooks orbiting the legislative pork barrel.

    • Marx Louis Wang

      LOL! Bawa’t corrupt na senador maraming moon na aali-aligid.

    • batangpaslit

      sa sobrang galit, nadamay ang buwan ng Neptune

  • Ehemalige Schatzkanzler Iris

    Once every 23 hours is really fast! No wonder it took them so long to find it.

    • Marx Louis Wang

      kasing fast ng moon na naka-amoy ng pork barrel.
