The radio source consists of three components: the supernova remnant Sagittarius A East, the spiral structure Sagittarius A West, and a very bright compact radio source at the center of the spiral, Sagittarius A* (read "A-star").
Sgr A terdiri dari tiga komponen, sisa-sisa supernova Sagittarius A Timur, struktur spiral Sagittarius A Barat, dan sumber radio yang sangat cerah di pusat spiral, Sagittarius A*.
These three overlap: Sagittarius A East is the largest, West appears off-center within East, and A* is at the center of West.
Ketiganya tumpang tindih: Sagittarius A Timur yang terbesar, Barat terletak sedikit di luar pusat Sgr A Timur, dan A* terletak di pusat Sgr A Barat.
Sgr A West has the appearance of a three-arm spiral, from the point of view of the Earth.
Sgr A Barat memiliki penampilan tiga-lengan spiral, yang mana terlihat dari sudut pandang Bumi.
This appearance and nickname are misleading, though: the three-dimensional structure of the Minispiral is not that of a spiral.
Penampilan dan sebutan ini adalah salah, karena: struktur tiga dimensi Spiral Mini bukanlah spiral.
The nature and kinematics of the Northern Arm cloud of Sgr A West suggest that it once was a clump in the CND, which fell due to some perturbation, perhaps the supernova explosion responsible for Sgr A East.
Sifat dan kinematika dari awan Lengan Utara Sgr A Barat menunjukkan bahwa dahulu merupakan awan CND, yang ambruk karena beberapa gangguan, diantaranya ledakan supernova Sgr A Timur.
Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy.
Para astronom memiliki bukti bahwa terdapat sebuah lubang hitam supermasif di wilayah pusat galaksi.
Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.
Sagittarius A* (disingkat Sgr A*) telah disetujui untuk menjadi kandidat yang paling masuk akal untuk lokasi lubang hitam supermasif ini.
The Very Large Telescope at Chile and Keck Telescope at Hawaii have detected stars orbiting Sgr A* at speeds greater than that of any other stars in the galaxy.
Very Large Telescope dan Teleskop Keck mendeteksi bintang yang mengorbit Sgr A* memiliki kecepatan yang lebih cepat daripada bintang-bintang lain di galaksi ini.
One star, designated S2, was calculated to orbit Sgr A* at speeds of over 5,000 kilometers per second at its closest approach.
Sebuah bintang, disebut S2, mengorbit Sgr A* dengan kecepatan 5.000 kilo per detik.
