This image shows Watson 021, a single H7 ordinary chondrite, weighing 135 g. The sample has a large crack, lined with alteration minerals, that runs down its middle and only one third of its fusion crust remains intact. This meteorite shows near complete oxidation of its reduced metal and sulfide phases making this a W4 chondrite. Watson 021 is extensively shocked, exhibiting globular silicate metal emulsions and shock veins that crosscut the sample. Tait et al found that microbial communities in samples of Nullarbor Plain soil are more diverse than those in Watson 021 and other meteorites, which are highly uniform in their species evenness and species richness.

Peering deep into the core of the Crab Nebula, this Hubble image reveals the beating heart of one of the most historic and intensively studied remnants of a supernova, an exploding star. The neutron star at the very center of the 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 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. This neutron star is a showcase for extreme physical processes and unimaginable cosmic violence. Bright wisps are moving outward from the neutron star at half the speed of light to form an expanding ring. It is thought that these wisps originate from a shock wave that turns the high-speed wind from the neutron star into extremely energetic particles. Image credit: NASA / ESA / J. Hester, ASU / M.
