Остатки соленой воды на Церере Salt Water Remnants on Ceres
1.09.2020

Does Ceres have underground pockets of water? Ceres, the largest asteroid in the asteroid belt, was thought to be composed of rock and ice. At the same time, Ceres was known to have unusual bright spots on its surface. These bright spots were clearly imaged during Dawn's exciting approach in 2015.


SS 433: двойная звезда – микроквазар APOD: 2020 August 31 Б SS 433: Binary Star Micro Quasar
31.08.2020

SS 433 is one of the most exotic star systems known. Its unremarkable name stems from its inclusion in a catalog of Milky Way stars which emit radiation characteristic of atomic hydrogen. Its remarkable behavior stems from a compact object, a black hole or neutron star, which has produced an accretion disk with jets.


NGC 6357: собор для массивных звезд NGC 6357: Cathedral to Massive Stars
30.08.2020

How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it one of the most massive stars known.


Свет и тени на Марсе Martian Chiaroscuro
29.08.2020

Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24, 2014 by the HiRISE camera on board the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers.


В долине Ориона The Valley of Orion
28.08.2020

This exciting and unfamiliar view of the Orion Nebula is a visualization based on astronomical data and movie rendering techniques. Up close and personal with a famous stellar nursery normally seen from...


Галактики с оболочками в Рыбах Shell Galaxies in Pisces
27.08.2020

This intergalactic skyscape features a peculiar system of galaxies cataloged as Arp 227 some 100 million light-years distant. Swimming within the boundaries of the constellation Pisces, Arp 227 consists of the two galaxies prominent right of center, the curious shell galaxy NGC 474 and its blue, spiral-armed neighbor NGC 470.


Небесный пейзаж в Лебеде APOD: 2020 August 26 Б Cygnus Skyscape
26.08.2020

In brush strokes of interstellar dust and glowing hydrogen gas, this beautiful skyscape is painted across the plane of our Milky Way Galaxy near the northern end of the Great Rift and the constellation Cygnus the Swan.


Аккреционный диск черной дыры: визуализация APOD: 2020 August 25 Б Visualization: A Black Hole Accretion Disk
25.08.2020

What would it look like to circle a black hole? If the black hole was surrounded by a swirling disk of glowing and accreting gas, then the great gravity of the black hole would deflect light emitted by the disk to make it look very unusual. The featured animated video gives a visualization.


Лунный полумесяц APOD: 2020 August 24 Б Crescent Moon HDR
24.08.2020

How come the crescent Moon doesn't look like this? For one reason, because your eyes can't simultaneously discern bright and dark regions like this. Called earthshine or the da Vinci glow...


Туманность Улитка от телескопов "Бланко" и "Хаббл" The Helix Nebula from Blanco and Hubble
23.08.2020

How did a star create the Helix nebula? The shapes of planetary nebula like the Helix are important because they likely hold clues to how stars like the Sun end their lives. Observations...
