Afternoon Delight

I spotted this on the SDO site late this afternoon…it shows an eruption of plasma from the Sun’s photosphere that stretches out many tens of thousands of miles…the Earth could easily fit many times over beneath the looping structure! This image is from about 5pm EDT (21:59 UT), and shows the eastern limb of the Sun,…

Craters Young and Old

  This image from NASA’s Lunar Reconnaissance Orbiter Camera (LROC) shows two similarly-sized craters in the Oceanus Procellarum (“Sea of Storms”) region of the Moon – a large mare on the Earth-facing side, on the northwestern edge. One crater is surrounded and covered by boulders and debris, denoting its young age compared to the smooth,…

There Goes The Sun

The Sun was briefly slashed in half diagonally when Earth’s atmosphere hid it from the view of NASA’s SDO spacecraft on April 1, 2011. (No foolin’!) SDO is currently in an orbit that puts the Earth between it and the Sun momentarily each day. When this happens, SDO’s view is blocked completely for several minutes…

The Colors of Mercury

Another new wide-angle image from MESSENGER in orbit, this is a color image of Mercury made from data taken in red, green and blue visible light wavelengths. Variations in surface textures and colorations can be seen, as well as long bright streaks running horizontally  – these are the ejecta rays extending from Hokusai Crater, off-frame…

Catchin’ Some Rays

One of the newest images from MESSENGER, now nice and comfy in orbit around Mercury, is of the bright Debussy crater and part of its extensive system of surrounding ejecta rays. The crater’s jagged central peak can be seen in this top-down view from the spacecraft’s narrow-angle camera (NAC). Also, here’s a new image of…

Is Mercury Hiding Water Ice?

  A new image from MESSENGER showing craters amidst smooth plains. Acquired March 29, 2011.   A new image from MESSENGER, released today March 30, 2011, shows relatively smooth plains near Mercury’s north pole dotted by some relatively large craters. Seen at an oblique angle, the low angle of sunlight emphasizes the relief of the…

First Image from Mercury Orbit!

It’s been over 11 days since MESSENGER established orbit around the planet Mercury, and we now have THE first image from orbit! The image above was obtained this morning, March 29 at 5:20am EDT as MESSENGER was above Mercury’s south pole – a portion of which has never previously been imaged by spacecraft. Click here…

Space Cell

I don’t usually post images from outside our solar system here on LITD, but this one was too good not to share! NASA’s Chandra X-ray observatory made this image of the Tycho supernova remnant, an object in our Milky Way galaxy about 13,000 light years from Earth, in the constellation Cassiopeia. In visible light it…

From the LITD Archives: But What About Venus?

Originally posted on April 7, 2009, only two months after Lights in the Dark launched: I haven’t posted anything yet about our other neighboring planet, Venus, mostly because the currently active mission exploring it, the European Space Agency’s Venus Express orbiter, hasn’t been updating much with new images since I’ve begun this site. Still, Venus…

Recycling the Empties

During a shuttle launch, the two white solid rocket boosters (SRB’s) attached to the main orange tank detach first* and fall back to Earth, landing in the Atlantic. These are retrieved by NASA ships and ferried back to be refurbished and refilled for the next mission…a process that requires the efforts of many experienced professionals,…

Success! Mercury has a new satellite named MESSENGER!

During a week of not-so-great news in the world (to understate things by quite a lot) it’s nice to report something good: the MESSENGER spacecraft has successfully established orbit around the planet Mercury, beginning its new 12-month mission of mapping and researching the innermost planet of our solar system! After traveling nearly 5 billion miles…

MESSENGER’s Day in the Sun

After 7 years and almost 5 billion of miles of traveling around the blistering inner solar system NASA’s MESSENGER spacecraft is finally ready for the moment it was created for: orbital insertion around Mercury, the innermost planet! At 9pm EDT tomorrow MESSENGER will attempt to establish orbit and if successful will become the first spacecraft…
