حل لغز إشارات كونية متكررة من نظام نجمي نادر

تمكن علماء الفلك من تفسير مصدر إشارات كونية متكررة حيّرت الباحثين لسنوات، بعد تتبعها باستخدام تلسكوب ASKAP الأسترالي. وتبيّن أن الإشارات تنشأ من نظام نجمي نادر يضم قزماً أبيض يسحب المادة من قزم أحمر مرافق، مولداً موجات راديوية وأشعة سينية كل 1.4 ساعة.

  • تمكن علماء الفلك من تفسير مصدر إشارات كونية متكررة حيّرت الباحثين لسنوات، بعد تتبعها باستخدام تلسكوب ASKAP الأسترالي. وتبيّن أن الإشارات تنشأ من نظام نجمي نادر يضم قزماً أبيض يسحب المادة من قزم أحمر مرافق، مولداً موجات راديوية وأشعة سينية كل 1.4 ساعة.
  • يساعد هذا الاكتشاف على تحسين فهم العلماء للأنظمة النجمية المتطرفة ومصادر الانبعاثات الراديوية الغامضة في الكون.
  • Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.

Why middle age is becoming a breaking point in the U.S.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.

Scientists mapped every neural connection in a fruit fly and found a surprise

A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
