TT Lebedya: uglerodnaya zvezda TT Cygni: Carbon Star
4.03.2001

TT Cygni is a cool red giant star with a wind. This false-color picture of TT Cyg was made using a coordinated array of millimeter wavelength radio telescopes and shows radio emission from carbon monoxide (CO) molecules in the surrounding gas.


"Apollon-12" naveshaet "Syurveior-3" Apollo 12 Visits Surveyor 3
3.03.2001

Apollo 12 was the second mission to land humans on the Moon. The landing site was picked to be near the location of Surveyor 3, a robot spacecraft that had landed on the Moon three years earlier.


LkHa101: Dyrka v ponchike LkHa101: The Hole in the Doughnut
2.03.2001

You'd need a really big cup of coffee with this doughnut ... because the hole in the middle is about a billion kilometers across. Centered on the Sun, a circle that size would lie between the orbits of Mars and Jupiter.


Maksimum solnechnoi aktivnosti Maximum Sun
1.03.2001

Astronomers recently witnessed an astounding, large scale solar event as the Sun's north and south magnetic poles changed places! But, this complete solar magnetic field flip was actually anticipated. It occurs every 11 years during the maximum of the solar activity cycle.


Kosmicheskaya stanciya vstrechaet svoyu "Sud'bu" A Space Station Meets its Destiny
28.02.2001

The International Space Station (ISS) had a date with Destiny earlier this month. More specifically, the crew of the Space Shuttle Atlantis installed the science laboratory named Destiny on the ISS. Destiny, pictured here, will also serve as a control center for the Earth orbiting space station.


Tumannost' Ved'mina Golova The Witch Head Nebula
27.02.2001

Double, double toil and trouble; Fire burn, and cauldron bubble -- maybe Macbeth should have consulted the Witch Head Nebula. This suggestively shaped reflection nebula is associated with the bright star Rigel in the constellation Orion.


Dyuny na Marse Sand Dunes on Mars
26.02.2001

Sand dunes on Mars can appear exotic. The dark dunes above might be compared to shark's teeth or chocolate confections. In reality, they arise from the complex relationship between the sandy surface and high winds on Mars.


Neitrinnyi detektor v Sedberi The Sudbury Neutrino Detector
25.02.2001

Two thousand meters below the ground, a giant sphere has begun to detect nearly invisible particles. These particles, neutrinos, are extremely abundant in the universe but usually go right through just about everything. By stocking this 12-meter sphere with an unusual type of hea


Infrakrasnaya Konskaya golova Infrared Horsehead
24.02.2001

This famous cosmic dust cloud was imaged in infrared light by the European Space Agency's Infrared Space Observatory (ISO) satellite. The false-color picture shows the bright infrared emission from dust and molecular gas in part of the Orion star forming region surrounding the Horsehead Nebula.


M55: diagramma cvet-velichina M55 Color Magnitude Diagram
23.02.2001

This color "picture" of globular star cluster M55 may not look like any star cluster you've ever seen. Still, it shows a most fundamental view for students of stellar astronomy. In the picture...
