Šaltinis – Astronomy.com – Resolving a galactic mystery
Ypač gili Chandra Rentgeno spindulių kosminės observatorijos artimos Galaktikos centrui srities nuotrauka atskleidė seną paslaptį apie Rentgeno spindulių foną ties galaktikos plokštuma. Fonas tirtame regione buvo sukeltas šimtų taškinių Rentgeno spindulių šaltinių.
Tyrimas truko 12 dienų. Plote, atitinkančiame 3% Mėnulio danguje užimamo ploto, buvo rasti 473 objektai, o iš [...]

Astronomers have just uncovered the true nature of what they thought was a regular supernova observed in January. At the time, it looked like a supernova emitting a 5-minute long burst of X-rays. But these X-rays were of a lower energy (known as “soft” X-rays) than expected leading some to believe this was a normal [...]

For the first time, a spacecraft has detected signals from both stars of a binary pulsar system in X-rays. XMM-Newton is watching both stars radiate pulsating X-rays, providing scientist with the perfect laboratory for high-energy physics and a never-ending source of intriguing physical problems. The binary pulsar PSR J0737-3039 was first spotted by astronomers in [...]
