Astronomy Picture Of the Day (APOD)

Красное северное сияние над Польшей APOD: 2024 May 12 Б Red Aurora over Poland

Northern lights don't usually reach this far south. Magnetic chaos in the Sun's huge Active Region 3664, however, produced a surface explosion that sent a burst of electrons, protons, and more massive, charged nuclei into the Solar System.

10.05.2024

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow.


Слияние двух черных дыр: моделирование Simulation: Two Black Holes Merge
9.05.2024

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
8.05.2024

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
7.05.2024

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.

6.05.2024

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
5.05.2024

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
4.05.2024

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
3.05.2024

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
2.05.2024

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.
