Спутник Gravity Probe B подтвердил наличие гравимагнетизма Gravity Probe B Confirms the Existence of Gravitomagnetism

Does gravity have a magnetic counterpart? Spin any electric charge and you get a magnetic field. Spin any mass and, according to Einstein, you should get a very slight effect that acts something like magnetism. This effect is expected to be so small that it is beyond practical experience and ground laboratory measurement.

Чудеса и загадки над Очень большими телескопами Wonder and Mystery above the Very Large Telescopes

What's that bright orange dot above the large telescope on the right? Even seasoned sky enthusiasts might ponder the origin of the orange orb seen by scrolling across this panoramic image, taken last December. Perhaps identifying known objects will help.

50 лет назад: полёт "Свободы-7" 50 Years Ago: Freedom 7 Flies

Fifty years ago, near the dawn of the space age, NASA controllers "lit the candle" and sent Mercury astronaut Alan Shepard arcing into space atop a Redstone rocket. His cramped space capsule was dubbed Freedom 7.

Следы небесных тел над Грецией Celestial Trails over Greece

If you watch the horizon at just the right place and at just the right time, you can witness some spectacular juxtapositions between Earth and sky. In the above video, stars, the Moon, and even a partially eclipsed Sun were recorded rising and setting over photogenic landmarks in Greece.

Шаровое скопление M15 с телескопа имени Хаббла Globular Cluster M15 from Hubble

Stars, like bees, swarm around the center of bright globular cluster M15. This ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way's center.
