HiPOD: Bedrock Exposures in Nirgal Vallis

This observation covers two tributaries and the main channel of Nirgal Vallis. The channel is approximately 610 kilometers long and is named after Nergal, the Babylonian god of war and counterpart to the Roman god of war, Mars. Mars Orbiter Camera image show light-toned bedrock; our high resolution picture can gives us a better view of the channel form and bedrock stratigraphy. (Grayscale cutout is less than 5 km across; enhanced color is less than 1 km.)

Another oldie from my draft folder. I’d like to do a mass deletion of 99% of my unposted drafts.

Peering deep into the core of the Crab Nebula, this close-up image reveals the beating heart of one of the most historic and intensively studied remnants of a supernova, an exploding star. The inner region sends out clock-like pulses of radiation and tsunamis of charged particles embedded in magnetic fields.

The neutron star at the very center of the Crab Nebula has about the same mass as the sun but compressed into an incredibly dense sphere that is only a few miles across. Spinning 30 times a second, the neutron star shoots out detectable beams of energy that make it look like it’s pulsating.

The Hubble Space Telescope snapshot is centered on the region around the neutron star (the rightmost of the two bright stars near the center of this image) and the expanding, tattered, filamentary debris surrounding it. Hubble’s sharp view captures the intricate details of glowing gas, shown in red, that forms a swirling medley of cavities and filaments. Inside this shell is a ghostly blue glow that is radiation given off by electrons spiraling at nearly the speed of light in the powerful magnetic field around the crushed stellar core.
