Earth and Jupiter Captured In the Same Photograph Taken From Mars
This is a photo of the Earth and its moon and Jupiter and its moons. In the same frame. It’s taken from Mars, and it’s humbling and incredible.

Space junk break down
Doing the math, that is 93% pure junk and only 7% useful satellites circling the earth. More disturbing, 50,000 uncatalogued objects larger than 1 cm (the largest size which modern shielding can likely deflect) are estimated to be spinning through space at hypervelocities.

Seven Sisters Versus California
On the upper right, dressed in blue, is the Pleiades. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and most easily visible open clusters on the sky. The Pleiadescontains over 3,000 stars, is about 400 light years away, and only 13 light years across. Surrounding the stars is a spectacular blue reflection nebula made of fine dust. A common legend is that one of the brighter stars faded since the cluster was named. On the lower left, shining in red, is the California Nebula. Named for its shape, the California Nebula is much dimmer and hence harder to see than the Pleiades. Also known as NGC 1499, this mass of red glowing hydrogen gas is about 1,500 light years away. Although about 25 full moons could fit between them, the above wide angle, deep field image composite has captured them both.

Great Observatories Explore Galactic Center
Where can a telescope take you? Four hundred years ago, a telescope took Galileo to the Moon to discover craters, to Saturn to discover rings, to Jupiter to discover moons, to Venus to discover phases, and to the Sun to discover spots. Today, in celebration of Galileo’s telescopic achievements and as part of the International Year of Astronomy, NASA has used its entire fleet of Great Observatories, and the Internet, to bring the center of our Galaxy to you. Pictured above, in greater detail and in more colors than ever seen before, are the combined images of the Hubble Space Telescope in near-infrard light, the Spitzer Space Telescope in infrared light, and the Chandra X-ray Observatory in X-ray light. A menagerie of vast star fields is visible, along with dense star clusters, long filaments of gas and dust, expanding supernova remnants, and the energetic surroundings of what likely is our Galaxy’s central black hole. Many of these features are labeled on a complementary annotated image. Of course, atelescope’s magnification and light-gathering ability create only an image of what a human could see if visiting these places. To actually go requires rockets.

Sunspots
Sunspots are cooler and less luminous than the rest of the sun because complex magnetic feilds prevent hot material from entering the area. In this image from the U.S. National Solar Observatory, the area arounf the spot appears granulated. Gas inside the star heats up and rises in columns of hot gas. Each granule can be more than 1,000 km across and usually lasts between eight and twenty minutes.
