Astronomy Picture Of the Day (APOD)

Сириус, Солнце, Луна и Южный Крест Sirius, Sun, Moon, and Southern Cross
7.07.2000

From left to right are the enclosures of Yepun (ye-poon; Sirius), Antu (an-too; Sun), Kueyen (qua-yen; Moon), and Melipal (me-li-pal; Southern Cross), pictured here as night falls at Paranal Observatory in northern Chile. These are the four 8.2 meter wide telescope units of the European Southern Observatory's Very Large Telescope (VLT).


Выброс из галактики М87 A Jet from Galaxy M87
6.07.2000

What's causing a huge jet to emanate from the center of galaxy M87? Although the unusual jet was first noticed early in the twentieth century, the exact cause is still debated. The above recently released picture taken by the Hubble Space Telescope shows clear details, however.


Центр Галактики в инфракрасных лучах The Galactic Center Across the Infrared
5.07.2000

The center of our Galaxy is obscured in visible light by dark dust that rotates with the stars in the Galactic Plane. In this century, however, sensors have been developed that can detect light more red that humans can see - light called infrared.


Приближение кометы LINEAR Comet LINEAR Approaches
4.07.2000

Just possibly, a new comet may become bright enough to see without binoculars later this month. Comet C/1999 S4 LINEAR is rapidly approaching both the Earth and the Sun from the outer Solar System, and should be at its brightest around 2000 July 25 in the early evening sky of northern observers.


Фронт ионизации в туманности Пеликан Pelican Nebula Ionization Front
3.07.2000

The Pelican Nebula is slowly being transformed. IC 5070, the official designation, is divided from the larger North America Nebula by a molecular cloud filled with dark dust. The Pelican, however, receives much study because it is a particularly active mix of star formation and evolving gas clouds.


Вспышки гамма-излучения Gamma Ray Burst: A Milestone Explosion
2.07.2000

Gamma-Ray Bursts (GRBs) were discovered by accident. Thirty three years ago today, satellites first recorded a GRB. The data plotted here show that the count rate of the satellite gamma-ray instrument abruptly jumped indicating a sudden flash of gamma-rays.


Вид Земли с Луны в ультрафиолетовом свете. Ultraviolet Earth from the Moon
1.07.2000

Here's a switch: the above picture is of the Earth taken from a lunar observatory! This false color picture shows how the Earth glows in ultraviolet (UV) light. UV light is so blue humans can't see it.


Звездный пейзаж в центре Галактики Galactic Centre Starscape
29.06.2000

Thirty thousand light-years distant, beyond the majestic dust clouds of the constellation Sagittarius, lies the centre of our Milky Way Galaxy. Hidden from optical view by the dust, the Galactic Centre region is a relatively unexplored starscape.


Карта гамма-всплесков на небе BATSE GRB Final Sky Map
28.06.2000

What causes the most powerful explosions in the universe? The BATSE modules that flew on the Compton Gamma Ray Observatory allowed more insight into enigmatic gamma-ray burst (GRB) explosions than ever before. From 1991-2000, BATSE detected 2704 GRBs, much more than ever previously recorded.


M63: Галактика Подсолнух M63: The Sunflower Galaxy
27.06.2000

One of the bright spiral galaxies visible in the north sky is M63, the Sunflower Galaxy. M63, also catalogued as NGC 5055, can be found with a small telescope in the constellation of Canes Venaciti.
