Крабовидная Туманность и пульсар Геминга в гамма-лучах Gamma Ray Crab, Geminga

What if you could "see" in gamma-rays? If you could, these two spinning neutron stars or pulsars would be among the brightest objects in the sky. This computer processed image shows the Crab Nebula pulsar (below and right of center) and the Geminga pulsar (above and left of center) in the "light" of gamma-rays.

Карта неба в гамма-диапазоне Gamma Ray Sky Map

What if you could "see" gamma rays? This computer processed image represents a map of the entire sky at photon energies above 100 million electron Volts. These gamma-ray photons are more than 40 million times more energetic than visible light photons and are blocked from the Earth's surface by the atmosphere.

Земля с Аполлона 17 Earth from Apollo 17

In 1972 Astronauts on the United States's last lunar mission, Apollo 17, took this picture looking back at the Earth on their way to the moon. The continents of Antarctica and Africa are visible below the delicate wisps of white clouds. For more information see NASA NSSDC press release.

Последствие великого взрыва Сверхновой в 1987 году Supernova 1987a Aftermath

In 1987 a star in one of the Milky Way's satellite galaxies exploded. In 1994 the Hubble Space Telescope, in orbit around the earth, took a very detailed picture of the remnants of this explosion. This picture, above, showed unusual and unexpected rings, and astronomers are not sure how they formed.

Звездное скопление Плеяды Pleiades Star Cluster

The Pleiades star cluster, M45, is one of the brightest star clusters visible in the northern hemisphere. It consists of many bright, hot stars that were all formed at the same time within a large cloud of interstellar dust and gas.

Если Земля была бы нейтронной звездой Neutron Star Earth

If the Earth could somehow be transformed to the ultra-high density of a neutron star , it might appear as it does in the above computer generated figure. Due to the very strong gravitational field, the neutron star distorts light from the background sky greatly. If you look closely, two
