Astronomy Picture Of the Day (APOD)

Карта наблюдаемой Вселенной APOD: 2023 July 5 Б A Map of the Observable Universe
4.07.2023

What if you could see out to the edge of the observable universe? You would see galaxies, galaxies, galaxies, and then, well, quasars, which are the bright centers of distant galaxies. To expand understanding...


Северное сияние над исландским водопадом APOD: 2023 July 4 Б Aurora over Icelandic Waterfall
3.07.2023

It seemed like the sky exploded. The original idea was to photograph an aurora over a waterfall. After waiting for hours under opaque clouds, though, hope was running out. Others left. Then, unexpectedly, the clouds moved away.


Венера в ультрафиолете от аппарата "Акацуки" APOD: 2023 July 3 Б Venus in Ultraviolet from Akatsuki
2.07.2023

Why is Venus so different from Earth? To help find out, Japan launched the robotic Akatsuki spacecraft which entered orbit around Venus late in 2015 after an unplanned five-year adventure around the inner Solar System.


Млечный Путь и полярное сияние над Антарктидой APOD: 2023 July 2 Б Milky Way and Aurora over Antarctica
1.07.2023

It was one of the better skies of this long night. In parts of Antarctica, not only is it winter, but the Sun can spend weeks below the horizon. At China's Zhongshan Station, people sometimes venture out into the cold to photograph a spectacular night sky.


Три галактики в Драконе Three Galaxies in Draco
30.06.2023

This tantalizing trio of galaxies sometimes called the Draco Group, is located in the northern constellation of (you guessed it) Draco, the Dragon. From left to right are face-on spiral NGC 5985, elliptical galaxy...


Орбиты потенциально опасных астероидов APOD: 2023 June 30 Б Orbits of Potentially Hazardous Asteroids
29.06.2023

Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Because some past mass extinction events have been linked to asteroid impacts, however, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth.


Послание от гравитационной Вселенной APOD: 2023 June 29 Б A Message from the Gravitational Universe
28.06.2023

Monitoring 68 pulsars with very large radio telescopes, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has uncovered evidence for the gravitational wave (GW) background by carefully measuring slight shifts in the arrival times of pulses. These shifts are correlated between different pulsars in a way that indicates that they are caused by GWs.


Мессье 24: звездное облако в Стрельце Messier 24: Sagittarius Star Cloud
27.06.2023

Unlike most entries in Charles Messier's famous catalog of deep sky objects, M24 is not a bright galaxy, star cluster, or nebula. It's a gap in nearby, obscuring interstellar dust clouds that allows a view of the distant stars in the Sagittarius spiral arm of our Milky Way galaxy.


Ультрафиолетовый Марс от аппарата MAVEN MAVEN s Ultraviolet Mars
26.06.2023

These two global views of Mars were captured at ultraviolet wavelengths, beyond the spectrum visible to human eyes. Recorded by the MAVEN spacecraft's Imaging Ultraviolet Spectrograph instrument in July 2022 (left) and January 2023, three otherwise invisible ultraviolet bands are mapped into red, green, and blue colors.


Пояс Венеры над горой Эверест APOD: 2023 June 26 Б The Belt of Venus over Mount Everest
25.06.2023

You've surely seen it, but you might not have noticed it. During a cloudless twilight, just before sunrise or after sunset, part of the atmosphere above the horizon appears slightly dark and off-color.
