Луна над Андромедой Moon Over Andromeda

The Great Spiral Galaxy in Andromeda (aka M31), a mere 2.5 million light-years distant, is the closest large spiral to our own Milky Way. Andromeda is visible to the unaided eye as a small...

IC 5067: вид крупным планом на эмиссионную туманность IC 5067: Emission Nebula Close up

This amazing skyscape lies along a bright ridge of emission in IC 5067, also known as The Pelican Nebula. Appropriately, the Pelican Nebula itself is part of a much larger, complex star-forming region about 2,000 light-years away in the high flying constellation Cygnus, the Swan.

Противосияние The Gegenschein

If you look carefully enough, you can even see the glow of the Sun in the opposite direction. At night this glow is known as the gegenschein (German for "counter glow"), and can be seen as a faint glow in an extremely dark sky. The gegenschein is sunlight back-scattered off small interplanetary dust particles.

Модернизация Международной космической станции Upgrading the International Space Station

The International Space Station (ISS) will be the largest human-made object ever to orbit the Earth. The station is so large that it could not be launched all at once -- it is being built piecemeal with large sections added continually by flights of the Space Shuttle.

Слухи о странной Вселенной Rumors of a Strange Universe

Eight years ago results were first presented indicating that most of the energy in our universe is not in stars or galaxies but is tied to space itself. In the language of cosmologists, a large cosmological constant is directly implied by new distant supernovae observations.

Аналемма и храм Олимпийского Зевса The Analemma and the Temple of Olympian Zeus

An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day throughout planet Earth's year. Above, 47 separate exposures (plus one foreground...

Виды Солнца с аппарата "Стерео-А" The View from Stereo Ahead

On December 22nd, at 0022 Universal Time the Sun reached its southernmost point in Earth's sky marking the final season change for the year 2006. In celebration of the Solstice, consider these images of the Sun from an extreme ultraviolet telescope onboard the Stereo Ahead spacecraft.

Запуск "Минотавра" на рассвете Minotaur Dawn

Last Saturday, some colorful dawn skies along the US east coast featured the Moon and a Minotaur rocket climbing into low Earth orbit. The 7AM launch of the four stage Air Force Minotaur I rocket took place at NASA's Wallops Flight Facility on Virginia's eastern shore.

Область звездообразования NGC 6357 Star Forming Region NGC 6357

For reasons unknown, NGC 6357 is forming some of the most massive stars ever discovered. Near the more obvious Cat's Paw nebula, NGC 6357 houses the open star cluster Pismis 24, home to these tremendously bright and blue stars.

Массивные звезды в рассеянном скоплении Писмис 24 Massive Stars in Open Cluster Pismis 24

How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it a record holder.
