科學家偵測到來自三十億光年遠的矮星系的外星訊號

Not only have scientists traced back the mystery alien signal to its host galaxy, they say that the latest signal intercepted by them by was accompanied by a stream of ONGOING, persistent weaker radio emissions. Both signals are apparently located 100 light years apart.

科學家們不只反追蹤這些神秘的外星訊號,一直追溯到它發源的主星系,他們還表示,最近一次截獲到的訊號伴隨著一個持續不變的、較弱的無線電波。兩種訊號相距一百光年。

Scientists have pinpointed –for the fist time ever— mysterious alien signals which originate from a dwarf galaxy located around 3 BILLION light years away.

The enigmatic, rare, and brief bursts of cosmic radio waves have been an enigma for astronomers ever since their discovery ten years ago.
So far, researchers have detected fast radio bursts eighteen times, and have remained confused since no one actually knows where they come from, or what might trigger them.

科學家們首次如此精確地確定外星訊號的來源,他們偵測到這些外星訊號是來自約三十億光年遠的矮星系( dwarf galaxy )。這神秘、罕見、簡短的宇宙無線電電波脈衝在十年前被發現,對天文學家來說,這些電波從被發現開始就一直是個謎。到目前為止,研究人員偵測到快速無線電脈衝共 18 次,他們對於這些脈衝到底從哪來一直充滿疑惑,對於是什麼產生這些脈衝也毫無頭緒。

Scientists speculate that FRB’s (Fast Radio Bursts) could be caused by massive stars, jets of material shooting out of black holes and of course, ALIENS.
FRB’s are usually extremely short radio waves and usually last no more than a millisecond.
The first one of these enigmatic alien messages was intercepted by Australia’s Parkes telescope in 2007. Out of the eighteen signals, only one of them has been heard repeatedly, which caused even greater confusion among experts.
It is precisely that repeated FRB –which was studied for six months— which allowed astronomers to pinpoint its exact location in the universe.

科學家認為快速電波爆發( fast radio burst,FRB )可以由巨大質量的恆星、從黑洞噴射出的物質噴射流產生,當然,外星人也是一個產生快速電波爆發的可能原因。快速電波爆發通常是極端簡短的無線電電波,通常持續不超過一毫秒。這個神秘的外星訊息在 2007 年時由澳洲的派克斯望遠鏡( Parkes telescope )首度發現。在十八個訊號中,只有一個被收聽到在不斷重複,讓專家們感到更為困惑。經過六個月的研究後,那個重複的快速電波爆發的來源位置被精確的定位出來。

According to experts, it originated from a faint dwarf galaxy located around three billion light years from Earth.
Referred to as FRB 121102, it was detected using the Very Large Array, a multi-antenna radio telescope.
Casey Law, from the University of California at Berkeley, said: “For a long time, we came up empty, then got a string of bursts that gave us exactly what we needed. All these threads point to the idea that in this environment, something generates these magnetars.”
“We are the first to show that this is a cosmological phenomenon. It’s not something in our backyard. And we are the first to see where this thing is happening, in this little galaxy, which I think is a surprise. Now our objective is to figure out why that happens,” added Law.

專家們表示,這個訊號是來自一個離地球約三十億光年遠的黯淡矮星系,它被稱為「 快速電波爆發 121102 」( FRB 121102 )。它是由甚大天線陣( Very Large Array,VLA )偵測到的,甚大天線陣是一種多天線的無線電望遠鏡。加州大學柏克萊分校( University of California at Berkeley )的 Casey Law 說:「 有很長一段時間,我們一無所獲,但接著就得到一連串脈衝訊號,而這正是我們所需要的。所有的線索指向一件事,也就是在這些訊號的產地環境中,因某種緣故產生了許多的磁星( magnetars )。我們是第一個表示這是宇宙現象的發表者,而且這不是一個發生在我們附近的現象。我們同時也是這個事件的發生地的首位發現者,而這個發生地就在那小小的星系中,我認為這是很令人驚訝的一件事。現在我們的研究主題是為何那樣的現象會發生。」

Speaking about the enigmatic message, Dr. Shriharsh Tendulkar, a member of the team from McGill University in Montreal, Canada said:
“Before we knew the distance to any FRBs, several proposed explanations for their origins said they could be coming from within or near our own Milky Way galaxy. We now have ruled out those explanations, at least for this FRB.”
What caused even greater confusion among scientists is that the FRB seemed to be accompanied by a stream of ONGOING, persistent weaker radio emissions.
Experts looked with detail into the mystery and found that the two emission sources were most likely no more than 100 light years apart.
The findings have been detailed in the journals Nature and Astrophysical Journal Letters.

說到類似這樣的神秘訊息,就要提到加拿大蒙特利爾的麥吉爾大學的 Shriharsh Tendulkar 博士,他說:「 在我們知道任何快速電波爆發的距離之前,有些提案對訊號來源地的解釋是,它們可能是從我們銀河系中,或是從我們銀河系附近來的。現在我們已經排除了這些假設提案,至少是針對這個快速電波爆發的提案。」

但是,讓科學家更為疑惑的是,伴隨著這個快速電波爆發的是另一個持續不變的、較弱的無線電波。專家們對此進行詳細觀察,發現這兩種訊號相距不超過一百光年。這個發現被詳細記載在自然( Nature )雜誌和天文物理期刊通訊( The Astrophysical Journal Letters )中。

Co-author Dr. Shami Chatterjee, from Cornell University in the US, said: “Finding the host galaxy of this FRB, and its distance, is a big step forward, but we still have much more to do before we fully understand what these things are.”
“We think that the bursts and the continuous source are likely to be either the same object or that they are somehow physically associated with each other,” said Dr Benito Marcote, from the Joint Institute for VLBI (Very Long Baseline Interferometry) in Dwingeloo, the Netherlands.

美國康乃爾大學的 Shami Chatterjee 博士,同時也是共同作者,說:「 找到這個快速電波爆發的來源主星系,以及它的距離,是一個很大的進展,但是我們在完全理解這些事物前,還有很多路要走。」

Benito Marcote 博士,來自甚長基線干涉測量( Very-long-baseline interferometry,VLBI )的荷蘭溫格路聯合研究所,他說:「 我們認為這個快速電波爆發以及持續訊號的來源很可能是同一個物體,或是某些因未知原因而互相有物理連結的物體們。」
