    Of course they're different...the Martians are causing them to strobe out the message 'Keep your junk off our planet'.

    Too bad no one on Earth understands Martian Morse code...

  3. Don'l look like much by pegasustonans · · Score: 5, Interesting

    I've seen the Borealis here on Earth, and they're beautiful. I can't imagine what they must look like in a Martian night.

    Well, considering they're estimated to be about 1% as powerful, I'd have to venture a guess that they really don't look like much at all. At least not in visible light.

  4. Aurora Borealis? NO! Aurora Australis! by Bananatree3 · · Score: 4, Informative
    FTA:Auroras were detected from Terra Cimmeria in the southern hemisphere of Mars.

    southern hemispher auroras are called Aurora Australis. Nothern Hemisphere auroras are Aurora Borealis.

      The terms "Borealis" and "Australis" are somewhat meaningless on Mars. The correct term is simply "Aurora". It's the editors who made the goof.

      Borealis, Boreas - The great north wind; greek god of. aka Aquilo
      Australis, Auster - The great south wind; roman god of. aka Notus

      Aurora - latin / middle english - Dawn

      If you want to be anal about the subject, Aurora Aquilonis would be a bit more consistent with the Roman theme. But both words would apply on other planets just as well as they do on earth as it means the dawn north or south wind.

    Uranus and Neptune probably have them too, but are too far away to see them clearly from Earth-based telescopes.

    Even though the aurora was observed in the southern hemisphere of Mars, it doesn't mean it should automatically be called aurora australis. They're called borealis and australis on Earth because they're caused by the magnetic field lines going to the northern and southern poles, respectively.

    However, because Mars' magnetic field is too weak to create the phenomenon by similar means, the aurora is caused by a separate mechanism, namely the magnetic anomalies described in the article, which can occur anywhere on the planet. For this reason, it should not be called aurora borealis or aurora australis, but rather aurora [insert god of magnetic rocks here].
