این تصویر متعلق به کهکشانی بنام
Messier 82 یا M82
می باشد که دوازده میلیون سال نوری با ما فاصله دارد
در سال 2010، ستاره شناسان و محققان در اطراف این کهکشان جسمی را مشاهده کردند که با سرعتی حدود چهار برابر
سرعت نور حرکت می کرد و از خود امواج رادیویی پخش می کرد
منبع و دلیل چنین امواجی هنوز مشخص نشده است و برای خود رمز و رازی باقی مانده است
آیا واقعا موجودات دیگری در آن کهکشان دنیای بسیار پیشرفته تر و مدرنی تری دارند؟
پیش و پس از آن ، چنین پدیده ای هرگز در مشاهدات فضانوردان و ستاره شناسان رخ نداده بود و رخ نداد. هیچیک از فرضیه هایی که تاکنون برای توضیح این پدیده مطرح شده اند ، به دلایل مختلف به اثبات نرسیده اند.

Unknown Object[edit source | editbeta]
In April 2010, radio astronomers working at the Jodrell Bank Observatory of the University of Manchester reported an unknown object in M82. The object started sending out radio waves, and the emission did not look like anything seen anywhere in the universe before.[10] There have been several theories about the nature of this unknown object, but currently no theory entirely fits the observed data.[10] It has been suggested that the object could be an unusual "micro quasar", having very high radio luminosity yet low X-ray luminosity, and being fairly stable, it could be an analogue of the low X-ray luminosity Galactic microquasar SS 433.[11] However, all known microquasars produce large quantities of X-rays, whereas the object's X-ray flux is below the measurement threshold.[10] The object is located at several arcseconds from the center of M82 which makes it unlikely to be associated with a Supermassive black hole. It has an apparent superluminal motion of 4 times the speed of light relative to the galaxy center.[12][13] Apparent superluminal motion is consistent with relativistic jets in massive black holes, and does not indicate that the source itself is moving above lightspeed.

Thank you.
ReplyDeleteThe key phrase in the article is “Superluminal motion.” This discernible fact is caused by quasar emitting the high-velocity jets. The jets are traveling close to the speed of light and at a very small angle towards the observer, which in turn provides the illusion of faster-than-light travel. Notice that it says, “Apparent superluminal motion is consistent with relativistic jets in massive black holes, and does not indicate that the source itself is moving above light speed.”
