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.

O_o  When we peer deep into space, we don’t expect to find something staring back at us…

This galactic ghoul, captured by our Hubble Space Telescope, is actually a titanic head-on collision between two galaxies. Each “eye” is the bright core of a galaxy, one of which slammed into another. The outline of the face is a ring of young blue stars. Other clumps of new stars form a nose and mouth.

Although galaxy collisions are common most of them are not head-on smashups like this Arp-Madore system. Get spooked & find out what lies inside this ghostly apparition, here.

USS Harry S. Truman Strike Group Flyover

The U.S. Navy Flight Demonstration Squadron, the Blue Angels, flew over Nimitz-class aircraft carrier, USS Harry S. Truman (CVN 75), on a return transit to Naval Air Station Pensacola following their annual flight over the U.S. Naval Academy commissioning ceremony May 20, 2020. The Harry S. Truman Carrier Strike Group (HSTCSG) remains at sea in the Atlantic as a certified carrier strike group force ready for tasking in order to protect the crew from the risks posed by COVID-19, following their successful deployment to the U.S. 5th and 6th Fleet areas of operation.

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.)
