SitiWanMahani - “objek pelik dan ganjil” mengejutkan dan tidak
pernah lagi dilihat dengan 6 ekor telah ditangkap oleh Teleskop Angkasa Hubble
NASA dalam lingkaran asteroid sistem suria kita yang di antara orbit Marikh dan
Musytari.
Ahli-ahli sains adalah “benar-benar terperanjat”
kerana mereka telah cuba untuk mencari penjelasan yang mencukupi untuk keluar
dari rupa DUNIA ini “objek pelik dan ganjil,” kata penyiasat utama dari Universiti
California di Los Angeles, David Jewitt, dalam akhbar NASA melepaskan.
Walaupun asteroid biasa muncul sebagai cahaya titik
kecil, yang ditetapkan P/2013 P5 mempunyai 6 ekor seperti komet debu terpancar daripadanya.
“Yang lebih menakjubkan, struktur ekornya berubah
secara dramatik dalam masa 13 hari kerana ia ‘belches’ keluar debu. Itu juga
kita terperangkap dengan kejutan. Adalah sukar untuk percaya bahawa kita sedang
melihat asteroid.”
Asteroid adalah sisa-sisa pembentukan planet
terganggu terletak di tali pinggang antara Marikh dan Musytari. Objek pepejal
yang boleh menjadi planet tetapi proses itu telah diganggu oleh tarikan graviti
Musytari. Asteroid berbeza dari komet kerana mereka didapati lebih dekat dengan
matahari dan tidak menghasilkan suasana yang sementara. Bagi komet, mereka
disifatkan sebagai yang agak kecil, pada masa-masa aktif, objek yang ais boleh
menguap dalam cahaya matahari yang membentuk suasana yang boleh dilihat di
seluruhnya ia dipanggil ‘koma’ atau ‘ekor’.
Pasukan penyelidikan itu percaya bahawa asteroid
berputar sehingga permukaannya terbang selain debu ejecting dalam letusan
episod yang membentuk ekor yang kelihatan dan membuat ia kelihatan seperti
sebuah komet.
“Jika kadar putaran asteroid ini menjadi cukup
pantas graviti lemah asteroid tidak lagi akan dapat untuk memegang ia
bersama-sama. Debu mungkin runtuhan ‘downslope’ ke arah khatulistiwa, dan
mungkin pecah dan jatuh, akhirnya hanyut ke dalam ruang untuk membuat ekor,” kata
Jewitt .
Is it a
comet? Is it asteroid? ‘Freakish’ six-tail space rock
discovered by NASA . . .
A startling and never yet seen “weird and freakish
object” with six tails has been captured by NASA's Hubble Space Telescope in
our solar system’s asteroid belt between the orbits of Mars and Jupiter.
Scientists were “literally dumbfounded” as they were
trying to find an adequate explanation for out of- this world appearance of
this “weird and freakish object,” said the lead investigator of the University
of California at Los Angeles, David Jewitt, in NASA’s press-release.
While normal asteroids appear as tiny points of
light, the designated P/2013 P5 has six comet-like tails of dust radiating from
it.
“Even more amazing, its tail structures changed
dramatically in just 13 days as it belches out dust. That also caught us by
surprise. It's hard to believe we're looking at an asteroid.”
Asteroids are remnants of disrupted planet formation
located in the belt between Mars and Jupiter. These solid objects that could
have become planets but the process was interrupted by the gravitational pull
of Jupiter. Asteroids differ from comets as they are found closer to the sun
and do not produce a temporary atmosphere. As for comets, they are
characterized as relatively small, at times active, objects whose ices can
vaporize in sunlight forming a visible atmosphere around it called a ‘coma’ or
a ‘tail.’
The research team believes that the asteroid is
rotating so much that its surface is flying apart ejecting dust in episodic
eruptions that form the visible tails and make it look like a comet.
“If the asteroid's spin rate became fast enough the
asteroid's weak gravity would no longer be able to hold it together. Dust might
avalanche downslope towards the equator, and maybe shatter and fall off,
eventually drifting into space to make a tail,” Jewitt said.

Dalam proses berputar objek dengan lingkungan 700
kaki telah hilang hanya sebahagian kecil daripada besar-besaran, yang dipanggil
100 hingga 1,000 tan debu, kata penyelidik.
“Orbit asteroid boleh membuat ahli keluarga asteroid
Flora. Ini bermakna bahawa ia adalah mungkin sebahagian daripada perlanggaran
asteroid yang berlaku kira-kira 200 juta tahun yang lalu” kata penyiasat utama.
Serpihan dari perlanggaran mengikuti orbit yang
sama, dipanaskan kepada sebanyak 815.5 Celsius. Ini menunjukkan bahawa asteroid
terdiri daripada batuan metamorf, yang tidak mampu memegang ais, menunjukkan
bahawa ia adalah satu asteroid dan bukan sebuah komet.
Asteroid mula terpancar debu 5 bulan lalu, berkata
kajian yang disiarkan dalam isu minggu ini ‘Astrophysical Journal Letters’.
Ia pertama kali ditemui oleh teleskop kaji selidik
Pan-STARRS di Hawaii sebagai objek luar biasa yang berpandangan kabur, manakala
beberapa ekor ditemui oleh Hubble pada 10 September. Imej yang diambil oleh
Teleskop kemudian pada 23 September menunjukkan objek yang berbeza secara
drastik mempesonakan penyelidik.
“Kami benar-benar mengetuk keluar,” kata Jewitt,
sambil menambah bahawa objek itu kelihatan seolah-olah keseluruhan struktur
telah mengayunkan sekitarnya selepas pemerhatian sebelumnya.
Penyelidik berkata perpecahan putaran mesti menjadi
fenomena biasa dalam lingkaran asteroid, menunjukkan bahawa ini mungkin cara
yang asteroid kecil mati.
“Dalam bidang astronomi, di mana anda mencari satu,
anda akhirnya menemui berbagai-bagai lagi” kata Jewitt. “Ini hanya satu objek
yang hebat untuk kita, dan hampir pasti yang pertama daripada banyak lagi yang
akan datang”.
In the process of spinning the object with a
700-foot radius has lost only a small fraction of its mass, supposedly 100 to
1,000 tons of dust, the researchers said.
“The orbit of the asteroid could make it a member of
the Flora asteroid family. This means that it is probably a piece from an asteroid
collision that occurred roughly 200 million years ago” said the lead
investigator.
The fragments from the collision are following
similar orbits, heated to as much as 815.5 Celsius. This indicates that the
asteroid is made up of metamorphic rocks, which are not capable of holding ice,
suggesting that it is an asteroid and not a comet.
The asteroid started radiating dust five months ago,
said the study published in this week’s issue of The Astrophysical Journal
Letters.
It was first spotted by Pan-STARRS survey telescope
in Hawaii as an unusually fuzzy-looking object, while the multiple tails were
discovered by Hubble on September 10. The images taken by Hubble later on
September 23 showed a drastically different object dazzling the researchers.
“We were completely knocked out,” Jewitt said,
adding that the object looked as if the entire structure had swung around after
the previous observation.
Researchers said rotational breakup must be a common
phenomenon in the asteroid belt, suggesting that this may be the way that small
asteroids die.
“In astronomy, where you find one, you eventually
find a whole bunch more,” Jewitt said. “This is just an amazing object to us,
and almost certainly the first of many more to come.”
