Кольцеобразная туманность Шепли-1 Shapley 1: An Annular Planetary Nebula

This strange structure is what can result when a normal star runs out of nuclear fuel in its core. At that time, the center condenses into a white dwarf while the outer atmospheric layers are expelled into space and appear as a planetary nebula.

Чудная планетарная туманность NGC 5189 NGC 5189: A Strange Planetary Nebula

After a Sun-like star can no longer support fusion in its core, the center condenses into a white dwarf while the outer atmospheric layers are expelled into space and appear as a planetary nebula. This particular planetary nebula has a quite strange and chaotic structure.

Астронавты "Аполлон"-14 устанавливает "Лунный экспериментальный комплекс" Apollo 14 Deploys ALSEP

After the lunar module of Apollo 14 set down on the Moon, Astronauts Alan Shepard and Edgar Mitchell deployed the Apollo Lunar Surface Experiments Package (ALSEP) and collected samples of lunar material. The ALSEP scientific experiments included a seismometer sensitive to slight lunar surface movements, and charged particle detectors which measured the solar wind.

"Аполлон"-14 на Луне Apollo 14 on the Moon

The jewel-like glare from a brilliant sun reflects off the lunar module of the Apollo 14 mission to the Moon as it rests on the lunar surface in February 1971. Astronauts Alan Shepard and Edgar Mitchell walked on the Moon's surface while astronaut Stuart Roosa piloted the orbiting command module.

Спуск на Юпитер Descent To Jupiter

Hours ago, at about 5:00 pm EST (2200 GMT) December 7, Galileo's descent probe slammed into Jupiter's atmosphere. Above is an artist's vision of the probe's planned descent from a dramatic perspective.

Юпитерианский зонд с "Галилео" Galileo's Jupiter Probe

Today, at about 5:00 pm EST, this 750 pound probe from NASA's robot spacecraft Galileo will plummet into Jupiter becoming the first probe to fly through the atmosphere of a gas giant planet.

24 часа до встречи с Юпитером 24 Hours from Jupiter

NASA's robot spacecraft Galileo began its long voyage to Jupiter more than six years and 2.3 billion miles ago. About 24 hours from now it will reach its destination. On arrival (December...

Круговорот в центре NGC 4261 The Swirling Center of NGC 4261

What evil lurks in the hearts of galaxies? The above picture by the Hubble Space Telescope of the center of the nearby galaxy NGC 4261 tells us one dramatic tale. Here gas and dust are seen swirling near this elliptical galaxy's center into what is almost certainly a massive black hole.

Является ли GL 229B слабым коричневым карликом? GL 229B: An Elusive Brown Dwarf?

What type of matter makes up most of the universe? This question is arguably the most perplexing astronomical mystery of our time. A leading candidate is a type of dim, low mass star called a "brown dwarf" star.

Рентгеновская горячая сверхновая в галактике M81 An X-ray Hot Supernova in M81

In 1993, a star in the galaxy M81 exploded. Above is a picture of the hot material ejected by this supernova explosion. The picture was taken in X-rays with the Advanced Satellite for Cosmology and Astrophysics (ASCA).
