Planet Theia Portions of the Moon-forming impactor Theia survived throughout Earth's history in the deep mantle Description: Terrestrial planet formation concludes with giant impacts between early Solar System planets. The formation of Earth's Moon is widely considered the prime example of such an impact, yet no direct evidence has been found. In this week's issue, Qian Yuan and his colleagues demonstrate that two massive seismically-observed basal mantle structures may represent remnants of planet Theia’s mantle rock. The combination of high-resolution giant impact simulations, mantle convection models, mineral physics calculations, and seismic imaging suggests that the lower half of Earth’s mantle remained mostly solid after this impact, and that parts of Theia’s mantle sank and accumulated atop Earth's core nearly 4.5 billion years ago, survived there throughout Earth’s history.

This image shows the “moonrise” of the satellite as it emerges from behind asteroid Dinkinesh as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI), one of the most detailed images returned by NASA’s Lucy spacecraft during its flyby of the asteroid binary. This image was taken at 12:55 p.m. EDT (1655 UTC) Nov. 1, 2023, within a minute of closest approach, from a range of approximately 270 miles (430 km). From this perspective, the satellite is behind the primary asteroid. The image has been sharpened and processed to enhance contrast.

This release features a composite image of a pulsar wind nebula, which strongly resembles a ghostly purple hand with sparkling fingertips. A pulsar is a highly magnetized collapsed star that rotates and creates jets of matter flowing away from its poles. These jets, along with intense winds of particles, form pulsar wind nebulae. Here, the pulsar wind nebula known as MSH 15-52 resembles a hazy purple cloud set against a black, starry backdrop. Both NASA's Chandra X-ray Observatory and the Imaging X-ray Polarimetry Explorer (IXPE) have observed MSH 15-52. Their observations revealed that the shape of this pulsar wind nebula strongly resembles a human hand, including five fingers, a palm and wrist. The bright white spot near the base of the palm is the pulsar itself. The three longest fingertips of the hand-shape point toward our upper right, or 1:00 on a clock face. There, a small, mottled, orange and yellow cloud appears to sparkle or glow like embers. This orange cloud is part of the remains of the supernova explosion that created the pulsar. The backdrop of stars was captured in infrared light.

NASA's James Webb Space Telescope has gazed at the Crab Nebula in the search for answers about the supernova remnant's origins. Webb's NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) have revealed new details in infrared light. Similar to the Hubble optical wavelength image released in 2005, with Webb the remnant appears comprised of a crisp, cage-like structure of fluffy red-orange filaments of gas that trace doubly ionized sulfur (sulfur III). Among the remnant's interior, yellow-white and green fluffy ridges form large-scale loop-like structures, which represent areas where dust particles reside.

SYDNEY, AUSTRALIA - MAY 26: A super blood moon is seen during a total lunar eclipse on May 26, 2021 in Sydney, Australia. It is the first total lunar eclipse in more than two years, which coincides with a supermoon. A super moon is a name given to a full (or new) moon that occurs when the moon is in perigee - or closest to the earth - and it is the moon's proximity to earth that results in its brighter and bigger appearance.
