Astronomy Picture Of the Day (APOD)

Туманность Лагуна в трех цветах The Lagoon Nebula in Three Colors
6.10.2002

The bright Lagoon Nebula is home to a diverse array of astronomical objects. Particularly interesting sources include a bright open cluster of stars and several energetic star-forming regions. When viewed by eye, cluster light...


Лебедь-A  в рентгеновских лучах X Ray Cygnus A
5.10.2002

Amazingly detailed, this false-color x-ray image is centered on the galaxy Cygnus A. Recorded by the orbiting Chandra Observatory, Cygnus A is seen here as a spectacular high energy x-ray source. But it is actually more famous at the low energy end of the electromagnetic spectrum as one of the brightest celestial radio sources.


Смотря в лицо NGC 6946 Facing NGC 6946
4.10.2002

From our vantage point in the Milky Way Galaxy, we see NGC 6946 face on. The big beautiful spiral galaxy is located just 10 million light-years away, behind a veil of foreground stars in the high and far-off constellation of Cepheus.


V838 Mon: загадочная звезда V838 Mon: Mystery Star
3.10.2002

A leading candidate for the most mysterious star found in recent times is variable star V838 Monocerotis. At a distance of about 8,000 light-years, V838 Mon was discovered to be in outburst in January of this year.


Звездные облака в Южной Короне Star Clouds Toward the Southern Crown
2.10.2002

The flowing trails of dust toward Corona Australis, the constellation of the Southern Crown, are visible here because not because they glow, but because they absorb and reflect. The dust appears bluer when seen near bright stars because it preferentially reflects blue light.


Прямоугольные горные хребты на Марсе Rectangular Ridges on Mars
1.10.2002

What could cause rectangular ridges on Mars? As data flows in from the two spacecraft currently orbiting Mars, surface structures are seen that are not immediately understood. These structures pose puzzles that planetary geologists are eager to solve, as they might provide clues to past processes that have shaped Mars over billions of years.


Бактерия  D. rad: кандидат в астронавты D rad Bacteria: Candidate Astronauts
30.09.2002

These bacteria could survive on another planet. In an Earth lab, Deinococcus radiodurans (D. rad) survive extreme levels of radiation, extreme temperatures, dehydration, and exposure to genotoxic chemicals. Amazingly, they even have the ability to repair their own DNA, usually with 48 hours. Known as an extremophile, bacteria such as D.


Пролетая мимо Венеры Venus: Just Passing By
29.09.2002

Venus, the second closest planet to the Sun, is a popular way-point for spacecraft headed for the gas giant planets in the outer reaches of the solar system. Why visit Venus first? Using...


Рентгеновские радуги X Ray Rainbows
28.09.2002

A drop of water or prism of glass can spread out visible sunlight into a rainbow of colors. In order of increasing energy, the well known spectrum of colors in a rainbow runs red, orange, yellow, green, blue, indigo, violet.


Моделирование аккреционного диска Accretion Disk Simulation
27.09.2002

Don't be fooled by the familiar symmetry. The graceful spiral structure seen in this computer visualization does not portray winding spiral arms in a distant galaxy of stars. Instead, the graphic shows spiral...
