Рентгеновские кольца вокруг гамма-всплеска X Ray Rings Around a Gamma Ray Burst

Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy.

Спиральная галактика с перемычкой NGC 1300 Barred Spiral Galaxy NGC 1300

Across the center of this spiral galaxy is a bar. And at the center of this bar is smaller spiral. And at the center of that spiralбis a supermassiveбblack hole.б This all happens...

Гамма-всплеск GRB 221009A GRB 221009A

Gamma-ray burst GRB 221009A likely signals the birth of a new black hole, formed at the core of a collapsing star long ago in the distant universe. The extremely powerful blast is depicted in this animated gif constructed using data from the Fermi Gamma Ray Space Telescope.

"Фалькон" и Охотничья Луна The Falcon and the Hunter s Moon

The Full Moon of October 9th was the second Full Moon after the northern hemisphere autumnal equinox, traditionally called the Hunter's Moon. According to lore, the name is a fitting one because this Full Moon lights the night during a time for hunting in preparation for the coming winter months.

Пылевые оболочки вокруг WR 140 от телескопа "Джеймс Вебб" Dust Shells around WR 140 from Webb

What are those strange rings? Rich in dust, the rings are likely 3D shells -- but how they were created remains a topic of research. Where they were created is well known: in a binary...

Ou4: туманность Гигантский Кальмар Ou4: The Giant Squid Nebula

A mysterious squid-like cosmic cloud, this nebula is very faint, but also very large in planet Earth's sky. In the image, composed with 30 hours of narrowband image data, it spans nearly three full moons toward the royal constellation Cepheus.

Звезды, пыль, столбы и струи в туманности Пеликан Stars, Dust, Pillars, and Jets in the Pelican Nebula

What dark structures arise within the Pelican Nebula? On the whole, the nebula appears like a bird (a pelican) and is seen toward the constellation of a different bird: Cygnus, a Swan. But inside, the Pelican Nebula is a place lit up by new stars and befouled by dark dust.

Двойная лунная аналемма над Турцией A Double Lunar Analemma over Turkey

An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day for one year. But the trick to imaging an analemma of the Moon is to wait bit longer.

Полярные сияния над северной Канадой Auroras over Northern Canada

Gusting solar winds and blasts of charged particles from the Sun resulted in several rewarding nights of auroras back in 2014 December, near the peak of the last 11-year solar cycle. The featured image captured dramatic auroras stretching across a sky near the town of Yellowknife in northern Canada.

Две кометы на южном небе Two Comets in Southern Skies

Heading for its closest approach to the Sun or perihelion on December 20, comet C/2017 K2 (PanSTARRS) remains a sight for telescopic observers as it sweeps through planet Earth's southern hemisphere skies. First...
