Possible Supernova Remnant Detected Near Milky Way’s Core

Astronomers using NASA’s Chandra and ESA’s XMM-Newton X-ray data, with radio and optical support from MeerKAT and Pan-STARRS, find a bright X-ray blob in the Sagittarius C region near the Galactic Center that could be a new supernova remnant. If confirmed, it would be one of the closest remnants to the Milky Way’s central black hole and is estimated to be about 1,700 years old, expanding at roughly two million miles per hour, though an alternative explanation involving a massive-star cluster remains possible and confirmation is pending.

Hubble Captures Crab Nebula’s Pulsar-Powered Expansion Over 25 Years

Hubble Space Telescope returns to the Crab Nebula after 25 years, documenting its rapid expansion (about 5.5 million km/h) and the evolving filaments driven by a central pulsar wind and synchrotron radiation, not just shock waves. The 2024 observations deepen our understanding of this supernova remnant, with findings published in The Astrophysical Journal.

Hubble captures 25-year evolution of the Crab Nebula

Astronomers compared two high-resolution Hubble images of the Crab Nebula taken in 1999/2000 and 2024, finding the iconic supernova remnant has expanded and changed shape over 25 years. The nebula’s filaments are moving outward at about 3.4 million mph, driven by energy from the central pulsar rather than a passing shock wave, and the new view reveals 3D structure and varying gas temperatures within the expanding shell.

Hubble Revisits Crab Nebula, Revealing Evolving Gas Clouds After 25 Years

NASA’s Hubble Space Telescope released new 2024 images of the Crab Nebula (Messier 1), taken 25 years after the initial look, showing moving gas clouds and changes in temperature, density, and chemistry as the remnant continues to expand (about 3.4 million mph) from its 1054 supernova, located roughly 6,500 light-years away in Taurus.

Hubble Traces a Quarter-Century of Crab Nebula Expansion

NASA's Hubble Space Telescope revisited the Crab Nebula, producing a 2024 image that, when paired with 1999 data, reveals the remnant's 25-year expansion and evolving filaments driven by the central pulsar wind. The study shows outward motion of filaments at about 3.4 million miles per hour and highlights how Hubble's longevity and upgraded instruments enable detailed 3D insights when combined with multiwavelength observations, including JWST, with findings published in The Astrophysical Journal.

Jellyfish Nebula in Gemini Resembles a Brain in Brilliant Space Photo

Space.com reports astrophotographer Ogetay Kayali captured IC 443—the Jellyfish Nebula—a 5,000‑light‑year‑old supernova remnant in Gemini near Propus. The image highlights the glowing hydrogen shell and intricate interstellar filaments, with a pulsar remaining from the explosion. Kayali notes the composition can resemble both a jellyfish and a brain, illustrating the remnant’s striking shell and its environment.

Astronomers Discover Mysterious Perfect Sphere in the Milky Way

Scientists have discovered a mysterious, perfectly spherical object named Teleios in the Milky Way that emits only radio signals and lacks visible or X-ray emissions, challenging existing theories about celestial structures and possibly representing a unique stellar remnant or cosmic bubble. Its precise nature remains uncertain, prompting further observations and research.
