اللهم صل على محمد
وآل محمد وعجل فرجهم والعن أعدائهم
اللهم صل على فاطمة وأبيها وبعلها وبنيها والسر العظيم المستودع فيها عدد ما أحاط به علمك
اللهم صل على مُحمد وآل مُحمد وعجل فرجهم واهلك عدوهم من الجن والإنس من الأولين والآخرين
Latest News: New observations by Hubble reveal a new twist on the Ring Nebula. The images show a more complex structure than astronomers once thought.
"The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," said C. Robert O'Dell of Vanderbilt University in Nashville, Tenn. "With Hubble's detail, we see a completely different shape than what's been thought about historically for this classic nebula. The new Hubble observations show the nebula in much clearer detail, and we see things are not as simple as we previously thought."
