GALEX: the Andromeda galaxy
A mere 2.5 million light years away, the Andromeda galaxy is as it were right next door. So close, and with a diameter of about 260,000 light years, which took 11 different fields of satellite images of the telescope Galaxy Evolution Explorer (GALEX) to create this magnificent view [...]

Cygnus X by the Herschel Observatory
This infrared image of Cygnus X, obtained by the Herschel Space Observatory, covering about 6 x 2 degrees of a region of massive star formation closer in the plane of our galaxy, the Milky Way. In fact, the rich stellar nursery containing the massive star cluster known as the association [...]

All the water on planet Earth
What part of the planet Earth is made of water? For a very small, really.
Although the oceans cover about water 70 percent of the land surface, oceans are shallow compared to the radius of the Earth. The illustration shows what would happen if all the water above it or [...]

Virtual flight over the asteroid Vesta
What would the asteroid Vesta fly?
Recently, the German Aerospace Center animators took the actual images and height data from NASA's Dawn mission, currently on a visit to Vesta, and created this virtual movie. The video starts with a sequence of Divalia Trench, an unusual pair of channels [...]

The spiral galaxy NGC 1672 from Hubble
Many spiral galaxies have bars across their centers. Even our galaxy, the Milky Way, appears to have a modest central bar.
The photograph, taken with a spectacular detail by the Hubble Space Telescope, shows the barred spiral galaxy NGC 1672. They are filamentous bands of dark dust, young clusters of stars [...]

The cluster of galaxies Hydra
Two stars in our galaxy, the Milky Way, set the foreground of this photograph cosmic. Beyond are the Hydra cluster galaxies.
Dominant galaxies near the center of this cluster, each of about 150,000 light years across, are three large galaxies: two yellow elliptical (NGC 3311 and NGC 3309) [...]

Sun vs. Moon Super
The superluna wins by little when you compare their apparent size to the Sun, as in this ingenious composition. To make it, photographed the full moon of May 6 with the same camera and telescope used to photograph the Sun (with a heavy sunscreen).
The next day. On May 6 the Moon was [...]

Flash green and superluna
While the so called superluna May 6, the biggest full Moon of 2012, stood on the pacific port, did not show any superhero. And while boats bobbed gently on the mooring next to the lighthouse La Perdrix, on the coast of Brittany (France), nor did any supervillain.
The output [...]

The shuttle Enterprise on New York
What's in the background?
In this photo taken last week stand two famous icons of New York. On the left stands the Statue of Liberty, a universal symbol, and right the Empire State Building, currently the second tallest building in the city. But [...]

The starlight
The time lapse video of the sky can be quite spectacular when they last long enough for stars, planets, auroras and clouds move in a few seconds. In these images, however, astrophotographer Daniel Lopez not only delights us with diverse and challenging time lapse sequences of the night sky but [...]
