Who, or what, dropped that jelly donut on Mars?

[CLICK ON IMAGE FOR HIGH RESOLUTION, Mars Exploration Rover Mission, Cornell, JPL, NASA] What if a rock that looked like a jelly donut suddenly appeared on Mars? That’s just what happened in front of the robotic Opportunity rover currently exploring the red planet. The unexpectedly placed rock, pictured above, was imaged recently by Opportunity after […]

Followed by a moon shadow: 1989 Neptune images from Voyager 2 reviewed 20 years later

[CLICK ON IMAGE FOR HIGH RESOLUTION,  NASA, JPL – Processed Image Copyright: Ted Stryk] Despina is a tiny moon of Neptune … discovered in 1989, in images from the Voyager 2 spacecraft taken during its encounter with the solar system’s most distant gas giant planet. But looking through the Voyager 2 data 20 years later, […]

Nearby M7 star cluster stands out in a sea of … stars, farther away at our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Lorand Fenyes] M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of the Scorpion (Scorpius). M7 contains about 100 stars […]

Alnitak, Alnilam, Mintaka: The glorious belt of Orion

[CLICK ON IMAGE FOR HIGH RESOLUTION /  Rogelio Bernal Andreo] Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion’s well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have […]

A rare triple-eclipse on Jupiter

[CLICK ON IMAGE FOR HIGH RESOLUTION] / Copyright: Leo Aerts This webcam and telescope image of banded gas giant Jupiter shows the transit of three shadows cast by Jupiter’s moons in progress, captured in Belgian skies on Oct. 12 at 0528 UT. Such a three shadow transit is a relatively rare event, even for a […]

A view of Saturn that would have been impossible from Earth

A view of Saturn that would have been impossible from Earth

[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA/JPL/SSI; Composition: Gordan Ugarkovic] This image of Saturn could not have been taken from Earth. No Earth based picture could possibly view the night side of Saturn and the corresponding shadow cast across Saturn’s rings. Since Earth is much closer to the Sun than Saturn, only the day […]
