Парад планетарных туманностей The Planetary Nebula Show

What do the Owl, the Cat's Eye, the Ghost of Jupiter, and Saturn have in common? They're all planetary nebulae of course(!), glowing gaseous shrouds shed by dying sun-like stars as they run out of nuclear fuel.

Астронавт, летящий над Землей A Flying Astronaut Over Earth

What would it be like to fly free over the seas and clouds of Earth? In 1994 astronaut Mark Lee found out when he tested the Simplified Aid for EVA Rescue (SAFER) system for NASA. SAFER is a backpack propulsion unit that incorporates small nitrogen thrusters controlled by hand and moderated by computer.

Глобальная пыльная буря на Марсе A Global Dust Storm on Mars

A dust storm on Mars can involve nearly the entire planet. As spring descended on the southern hemisphere of the red planet this June and July, a global dust storm raged. Pictured above is the storm on July 8 as it spread up from the south, oriented on the lower right.

IC 418: туманность Спирограф IC 418: The Spirograph Nebula

What is creating the strange texture of IC 418? Dubbed the Spirograph Nebula for its resemblance to drawings from a cyclical drawing tool, planetary nebula IC 418 shows patterns that are not well understood. Perhaps they are related to chaotic winds from the variable central star, which changes brightness unpredictably in just a few hours.

Железное Солнце The Iron Sun

The ultraviolet light emitted by eleven times ionized iron at temperatures over 2 million degrees Farenheit was used to record the above picture of the Sun on September 22, the date of the autumnal equinox.

NGC 6992: просвет в Вуали NGC 6992: A Glimpse of the Veil

After 5,000 years, the gorgeous Veil Nebula is still turning heads. Cataloged as NGC 6992, these glowing filaments of interstellar shocked gas are part of a larger spherical supernova remnant known as the Cygnus Loop or the Veil Nebula -- expanding debris from a star which exploded over 5,000 years ago.

Химические элементы в близкой спиральной галактике M33 Elements of Nearby Spiral M33

Spiral galaxy M33 is a mid-sized member of our Local Group of Galaxies. M33 is also called the Triangulum Galaxy for the constellation in which it resides. About four times smaller (in radius) than...

Ядро кометы Борелли Comet Borrelly's Nucleus

What does a comet nucleus look like? To answer this question, NASA controllers drove an aging probe through the hostile environs of a distant comet, expecting that even if comet fragments disabled the spacecraft, it would be worth the risk. The probe, Deep Space 1, survived.

Возвышенности и впадины Земли The Highs and Lows of Earth

What's up on planet Earth? A truly global answer has now been created by the Global Land One-km Base Elevation (GLOBE) Project. Pictured above is the best digital elevation map yet created...

Выбросы солнечных протуберанцев A Solar Prominence Erupts

Our Sun is still very active. Last year, our Sun went though Solar Maximum, the time in its 11-year cycle where the most sunspots and explosive activities occur. Sunspots, the Solar Cycle, and solar prominences are all caused by the Sun's changing magnetic field.
