Alien hunters detect 'strong signal' from star 95 light years away
The signal is from the direction of HD164595, a star that has at least one planet.
A "strong signal" detected by a radio telescope in Russia that is scanning the heavens for signs of extraterrestrial life has stirred interest among the scientific community.
"No one is claiming that this is the work of an extraterrestrial civilisation, but it is certainly worth further study," said Paul Gilster, author of the Centauri Dreams website which covers peer-reviewed research on deep space exploration.
The signal is from the direction of HD164595, a star about 95 light-years from Earth that is known to have at least one planet, and may have more.
The observation is being made public now, but was actually detected last year by the Ratan-600 radio telescope in Zelenchukskaya, Russia, he said.
Experts say it is far too early to know what the signal means or where, precisely, it came from.
"But the signal is provocative enough that the Ratan-600 researchers are calling for permanent monitoring of this target," wrote Mr Gilster.
The discovery is expected to feature in discussions at the 67th International Astronautical Congress in Guadalajara, Mexico, on September 27.
"Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilisation," Mr Gilster wrote, referring to a scale-system that indicates a civilisation far more advanced than our own.
"If it were a narrow beam signal focused on our Solar System, it would be of a power available to a Kardashev Type I civilisation," indicating one closer to Earth's capabilities.
Mr Gilster, who broke the story on August 27, said he had seen a presentation on the matter from Italian astronomer Claudio Maccone.
"Permanent monitoring of this target is needed," said the presentation.
Nick Suntzeff, a Texas A&M University astronomer, told the online magazine Ars Technica that the 11 gigahertz signal was observed in part of the radio spectrum used by the military.
"If this were a real astronomical source, it would be rather strange," Mr Suntzeff was quoted as saying.
"God knows who or what broadcasts at 11Ghz, and it would not be out of the question that some sort of bursting communication is done between ground stations and satellites," Mr Suntzeff said.
"I would follow it if I were the astronomers, but I would also not hype the fact that it may be at SETI signal given the significant chance it could be something military."

Malam Ahad lepas ada cahaya biru terang macam spotlight terbang2 melintasi rumah akak. Waktu tu jam 1 pagi. Punya akak teruja akak buka tabir nak lihat cahaya tu kot2 la boleh nampak UFO tapi dah terlambat, cahaya tu terbang cepat sangat. Bila akak buka tabir heshe cuma nampak sipi2. Tiba2 akak teringat kawan pernah nampak cahaya terang berwarna warni seperti disko ball terbang2 kat asrama sekolah weol. Dia pircaya itu hantu. Serta merta akak seram lalu pasang lampu untuk tido.  |

dlm bahasa mudah difahami,
1 tahun cahaya = berapa jauh a photon(cahaya) boleh travel dalam setahun
cahaya matahari ambil masa ~8 minit untuk sampai ke bumi, maka ia ambil sebanyak 8 minit cahaya mengikut perspektif kita
maka, untuk 1 tahun cahaya, cahaya akan sampai ke destinasinya selama satu tahun mengikut perspektif kita
oleh demikian,
signal tu boleh dikatakan 95 tahun yang lalu yang lampau yang baru dikesani dgn detector dr bumi kita..

antu penanggal
Penanggal biru ke chuol? Bukan bebola api merah2 gitew?
Harap cahaya biru tu buat penampakan lagi. Tapi sila muncul awal sikit, seblom jam 12 tengah malam ka. Walau takut aku berniat nak kejor. Ekceli masa nampak tu aku dah nak gi buka pintu rumah but then dah 1 pagi, takut ah tiba2 nampak langzuyar sengih2 kat pokok. |

mungkin di satu planet di sebuah galaksi dlm supercluster far far awaaaayy, makhluk2 extra terrestrial pernah dengar, bincangkan teori kewujudan kita dan cuba utk menghubungi kita serta makhluk2 ET yg lain. barangkali ada jugak set2 di sana yg gelakkan teori ittew -- mana ada makhluk lain yg wujud dlm alam semesta yg luas nih melainkan kita sajork? katanya... |
