Слияние двух черных дыр: моделирование Simulation: Two Black Holes Merge

Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust.

Галактика, джет и знаменитая черная дыра The Galaxy, the Jet, and a Famous Black Hole

Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant...

Аккреционный диск черной дыры: визуализация APOD: 2024 May 8 Б Visualization: A Black Hole Accretion Disk

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.

Аккрецирующая черная дыра с джетом APOD: 2024 May 7 Б Black Hole Accreting with Jet

What happens when a black hole devours a star? Many details remain unknown, but observations are providing new clues. In 2014, a powerful explosion was recorded by the ground-based robotic telescopes of the All Sky Automated Survey for SuperNovae (Project ASAS-SN), with followed-up observations by instruments including NASA's Earth-orbiting Swift satellite.

Полное солнечное затмение от полоски до кольца APOD: 2024 May 6 Б A Total Solar Eclipse from Sliver to Ring

This is how the Sun disappeared from the daytime sky last month. The featured time-lapse video was created from stills taken from Mountain View, Arkansas, USA on 2024 April 8. First, a small sliver of a normally spotted Sun went strangely dark.

Черная дыра разрушает пролетающую звезду APOD: 2024 May 5 Б A Black Hole Disrupts a Passing Star

What happens to a star that goes near a black hole? If the star directly impacts a massive black hole, then the star falls in completely -- and everything vanishes. More likely, though, the star goes close enough to have the black hole's gravity pull away its outer layers, or disrupt, the star.

Три вспомогательных телескопа 3 ATs

Despite their resemblance to R2D2, these three are not the droids you're looking for. Instead, the enclosures house 1.8 meter Auxiliary Telescopes (ATs) at Paranal Observatory in the Atacama Desert region of Chile.

Температура на экзопланете WASP-43b Temperatures on Exoplanet WASP 43b

A mere 280 light-years from Earth, tidally locked, Jupiter-sized exoplanet WASP-43b orbits its parent star once every 0.8 Earth days. That puts it about 2 million kilometers (less than 1/25th the orbital distance of Mercury) from a small, cool sun.

M100: галактика с регулярным спиральным узором M100: A Grand Design Spiral Galaxy

Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. The large galaxy of over 100 billion stars has well-defined spiral arms, similar to our own Milky Way.

IC 1795: туманность Рыбья голова APOD: 2024 May 1 Б IC 1795: The Fishhead Nebula

To some, this nebula looks like the head of a fish. However, this colorful cosmic portrait really features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia.
