Молекулярная карта Млечного Пути Milky Way Molecule Map
30.04.1997

Where are the Milky Way's gas clouds and where are they going? Stars form in gas clouds, and the motion of gas clouds tell us about the size and rotation speed of our own Milky Way Galaxy.


Комета Хейла-Боппа и созвездие Ориона Hale-Bopp and Orion
29.04.1997

Comet Hale-Bopp is still brighter than most constellations. In fact, Comet Hale-Bopp may now hold the record for staying bright the longest. Last week the comet was photographed above in the same field...


Натриевое облако Ио Io's Sodium Cloud
28.04.1997

Io has its own cloud. Jupiter's most active moon is visible on the left of the above false-color photograph, with its left side illuminated by sunlight. But what is happening on Io's right side? Here a plume of gas from the active volcano Prometheus also reflects sunlight.


Спутник: путешествующий компаньон Sputnik: Traveling Companion
27.04.1997

Sputnik means "traveling companion". Despite the innocuous sounding name, the launch of the Earth's first "artificial moon", Sputnik 1, by the Soviets on October 4, 1957 shocked the free world, setting in motion events which resulted in the creation of NASA and the race to the Moon.


Скопление галактик в Персее The Perseus Cluster of Galaxies
26.04.1997

Here is one of the largest objects that anyone will ever see on the sky. Each of the fuzzy blobs in the above picture is a galaxy, together making up the Perseus Cluster, one of the closest clusters of galaxies.


Поляризованная комета Хейла-Боппа Hale-Bopp Polarized
25.04.1997

Light polarization is familiar to many outdoor enthusiasts who use polarizing sunglasses to cut the glare of reflected light. These two views of comet Hale-Bopp also demonstrate the effect of polarization. At left...


Пенистый Млечный Путь The Frothy Milky Way
24.04.1997

Astronomers have recently discovered that looking at dust along the plane of our Milky Way Galaxy is a bit like looking into a frothy glass of beer. The dust between stars in our galaxy...


Антлия: новый галактический сосед Antlia: A New Galactic Neighbor
23.04.1997

Meet Antlia, a newly discovered neighbor of our Milky Way Galaxy. Announced just last week, this faint member of our Local Group of Galaxies has only about one million stars. It is late in being noticed because it is so hard to see against a bright sky.


Угасание исторической оптической вспышки Historic Optical Flash Fades
22.04.1997

The largest telescopes in the world have scrambled to point toward this faint, fading object. Why? Because it may well be the first active optical counterpart ever found for a gamma-ray burst, and could hold the clue to the distance scale to this most enigmatic class of astronomical objects.


Комета Большого неба Big Sky Comet
21.04.1997

On April 17th, "Big Sky" country sure lived up to its name. The dark skies over the US states of Wyoming, Montana and the Dakotas were quite busy, as shown by this photograph featuring Comet Hale-Bopp. In the foreground is the Absaroka Mountain Range in Wyoming, lit by reflected moonlight.
