ASA's Hubble Space Telescope has spotted a strange celestial "string of pearls" wrapped around the hearts of two merging elliptical galaxies.

The curly string is about 100,000 light-years long and sports blue "pearls" — actually huge young star clusters — every 3,000 light-years along the way, researchers said. You can zoom in on the beautiful structure, and learn more about it, in this new Hubble video.

"We were surprised to find this stunning morphology," study leader Grant Tremblay, of the European Southern Observatory in Garching, Germany, said in a statement. "We've long known that the 'beads on a string' phenomenon is seen in the arms of spiral galaxies and in tidal bridges between interacting galaxies. However, this particular supercluster arrangement has never been seen before in giant merging elliptical galaxies."

The two colliding galaxies, which lie within a cluster known as J1531+3414, are both about 330,000 light-years wide, researchers said. (For comparison, the disk of our own Milky Way spans about 100,000 light-years.)

Their merger has sparked an intense burst of star formation, resulting in the creation of the clusters of young, blue stars. The physics behind the string-of-pearls structure are similar to the processes that cause rain to fall in drops as opposed to steady streams, researchers said.

It's unclear where the cold gas that's fueling the star formation came from. It may have existed all along within the two merging galaxies, or it may have condensed from the bubble of superhot plasma surrounding the duo, perhaps cooling out of the shock wave created by the cosmic collision, researchers said.

"Whatever the origin for this star-forming gas is, the result is awesome," Tremblay said. "It's very exciting. You can't find a mundane explanation for t

عب عزيز
غايتو عناوينك بوستاتك دي لو ختيتها جنب بعض بتعملstring of pearls زي المذكورة في خبرك الجايبو دا!

يتحدث العلماء همسا،،ان الحياة بصورتها المثلي تكمن في ارض قريبة،،جبده بس،،مثاليه حتي انها عصية علي الادراك،،وانهم لغفلتهم ،كانو يقضون الطرف عن هذا الصعيد القريب،،حتي فوجئو به..
ما ابدع هذا الملكوت الرحماني،،وما اروع العلم،جاهدا لينتصر للحياة والخير.
يامصطفي ياخوي ات زول متفائل وزول علم،،،فخليك معانا الجماعة وصلو طب ،،ابشر.
