This video from the SOHO solar observatory spacecraft shows a a partial rotation of the Sun seen in ultraviolet light (the green color is from the specialized camera filter, corresponding to emissions at 1.5 million degrees Kelvin.) In the Sun’s northern hemisphere an energetic area of solar prominences can be seen, tens of thousands of…

Remembering Titan
This image was first released five years ago today, on January 15, 2005. It shows the murky surface of Saturn’s moon Titan as seen by the European Space Agency’s Huygens probe after it made its historic descent through the moon’s thick haze and clouds and landed in a frozen plain of methane mud and icy…
And still they comeā¦
Watching a video of SOHO images today, I noticed two more comets diving toward the Sun (located behind the white circle on the blue disc), on the 8th and the 9th. Both came from the same direction, from the lower left as seen in the still above. Watch the video here. With over 1500 comets…
The End of a Comet’s Tale
These two images, taken by the SOHO solar observatory spacecraft, show the last moments of a comet as it approaches the Sun in what turned out to be its final voyage…the Sun’s radiating energy sizzled the icy traveler shortly after. (See the video version on my earlier post.) The two images were taken with different…

The Outside Track
This quick animation was created from 6 raw images taken by Cassini on January 7. Focusing on Saturn’s rings from above, the little shepherd moon Daphnis can be seen emerging from the planet’s cast shadow. Traveling within the Keeler gap, 5-mile-wide Daphnis pushes the ring material in front of it into scalloped waves and kicks…
Final Flight
On January 3, the European Space Agency’s SOHO solar observatory spacecraft captured images of a comet flying towards the Sun….and then disappearing into it, evaporating in heat of the solar furnace. The video above, taken by the spacecraft’s Heliospheric Imager which monitors the activity of the Sun’s corona, clearly shows the comet’s final moments before…
Jet Setter
The icy Enceladus shows off its southern geysers, stately hovering in orbit around Saturn in this raw image from the Cassini spacecraft, taken on Christmas day. It is impressive to get such a clear view of the geysers with the low phase angle of the sunlight. Typically the geysers are only seen when the sun…
A Visit to Prometheus
This raw image, taken by the Cassini spacecraft on December 26, 2009 (on a certain space blogger’s birthday, by the way) shows an amazing view of Prometheus, one of Saturn’s many shepherd moons. This is the closest yet that Cassini has come to the 96-mile-long oblong moon. Details of its cratered surface are visible, as…
Reflecting on Titan
This soon-to-be historic image, released today, shows a glint of sunlight reflecting off the surface of a lake on Titan. Taken by the Cassini spacecraft’s Visual and Infrared Mapping Spectrometer (VIMS) in July 2009, the image has been extensively researched by scientists to make sure it was in fact a reflection off of a liquid…
Back in Action
“I know everything hasn’t been quite right with me. But I can assure you now, very confidently, that it’s going to be all right again.” This mesmerizing video montage showing beautiful high-resolution views of Martian landscapes opens with the fortunate foreshadowing of today’s news that the Mars Reconnaissance Orbiter has resumed full operations since being…
Off to Marquette
The rover Opportunity took this false-color photo of another possible stony meteorite dubbed “Marquette Island” on Monday December 7. These objects stand out on the barren sandy plain that Opportunity is currently traveling across on its way to Endeavour Crater and provide interesting targets for investigation. The rover has already used its Rock Abrasion Tool…
