هابل حلقه ای از ماده ی تاریک را آشکار کرد!

منجمان ناسا توسط تلسکوپ هابل توانسته اند حلقه ای از ماده ی تاریک را در آسمان نشانه روند. دیشب ( سه شنبه) محققان ناسا محکم ترین دلیل را برای وجود ماده ای مرموز که ربعی از جهان را در میان گرفته اعلام کردند. تا به حال با رصد مقدار کمی از ماده ی تاریک دانشمندان آن را منبع اضافی ای برای نیروی گرانش می دانستند.

Astronomers using NASA's Hubble Space Telescope have discovered a ghostly ring of dark matter that formed long ago during a titanic collision between two massive galaxy clusters. The ring's discovery is among the strongest evidence yet that dark matter exists. Astronomers have long suspected the existence of the invisible substance as the source of additional gravity that holds together galaxy clusters. Such clusters would fly apart if they relied only on the gravity from their visible stars. Although astronomers don't know what dark matter is made of, they hypothesize that it is a type of elementary particle that pervades the universe

US astronomers on Tuesday presented the most solid proof yet of the existence of dark matter, a mysterious substance believed to make up more than a quarter of the universe
Astronomers using NASA's Hubble Space Telescope have discovered a ghostly ring of dark matter that formed long ago during a titanic collision between two galaxy clusters. Dark matter makes up most of the universe's material. Ordinary matter, which makes up stars and planets, comprises only a small percent of the universe's matter. The ring's discovery is among the strongest evidence yet that dark matter exists.Astronomers have long suspected the existence of the invisible substance and theorized that it is the source of additional gravity that holds galaxy clusters together. Such clusters would fly apart if they relied only on the gravity from their visible stars. Although astronomers do not know what composes dark matter, they hypothesize that it is a type of elementary particle that pervades the universe
