JWST paints the Exposed Cranium Nebula in unprecedented detail

NASA's James Webb Space Telescope released two high‑resolution infrared images of the Exposed Cranium Nebula (PMR 1) using NIRCam and MIRI, revealing a brain‑like dark lane and distinct outer shell as a dying star sheds its layers; the two portraits—one from NIRCam and one from MIRI—show different internal details and illustrate Webb’s leap in resolution since the 2013 Spitzer image, while the star’s mass remains uncertain and its ultimate fate could be a supernova or a cooling white dwarf.

Ablaze in Auriga: Stunning Shot of the Flaming Star Nebula Around AE Aurigae

Astrophotographer Greg Meyer captured a dramatic long‑exposure view of the Flaming Star Nebula around the runaway star AE Aurigae in Auriga, about 1,500 light-years away. The flame-like glow comes from radiation emitted by AE Aurigae ionizing surrounding hydrogen; the image, captured with a Radian Raptor 61 mm telescope and nearly 21 hours of exposure, was processed in Adobe Lightroom and Photoshop with PixInsight to reveal a sprawling nebula scene that includes the Tadpole Nebula at the bottom.

Cosmic Planes: Why Our Solar System and Galaxy Are Flat

Cosmic Planes: Why Our Solar System and Galaxy Are Flat

The Sun and planets all orbit in a single, flat disk aligned to the ecliptic because the solar nebula collapsed with rotation; similarly, the Milky Way and Local Group lie in near-planes (galactic and supergalactic), though these planes tilt relative to one another. “Down” isn’t universal in space—it depends on the reference plane—demonstrating how initial angular momentum during formation shapes the cosmos’s familiar flat structure from the solar system outward.

Supernova Creates 'Hand of God' Nebula in Space

A supernova explosion has created a ghostly hand-shaped nebula in space, known as MSH 15-52, featuring a pulsar at its center. Using combined radio and X-ray data, astronomers have revealed intricate structures and interactions within the nebula, providing new insights into the aftermath of stellar explosions and the behavior of pulsars. Further research is needed to fully understand these cosmic phenomena.

"Stellar Merger Unveils Magnetic Monster: Solving Nebula Mysteries"

A bizarre binary star system, HD 148937, located 3,800 light-years away, contains two massive stars, one of which is the brightest and hottest known to have a magnetic field. Despite the conventional understanding that massive stars should not have magnetic fields, about 7% of them do. Recent observations suggest that the magnetic field in HD 148937's star was acquired through a violent merger with another star, leading to the creation of a bipolar nebula and shedding light on the origin of magnetic fields in massive stars.
