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.
NASA’s IXPE telescope has produced a new polarized image of RCW 86, the remnant of the supernova seen around AD 185, using X-ray polarization to probe the remnant’s outer rim and magnetic environment while noting slowed expansion in a low-density cavity.
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.
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.
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.
NASA's Chandra X-ray Observatory has released a 25-year time-lapse video showing the expansion of Kepler’s Supernova Remnant, providing valuable insights into the aftermath of a Type Ia supernova and its interaction with the surrounding environment, highlighting the importance of supernovae in cosmic evolution.
NASA released a detailed video of Kepler's Supernova remnant, created from 25 years of Chandra X-ray data, showcasing the explosion's debris moving at different speeds and providing insights into the supernova's environment and its role in cosmic evolution.
Astronomers have discovered a nearly perfect spherical object in the Milky Way, named Teleios, which is likely a supernova remnant from a Type Ia supernova, but its exact distance and age remain uncertain, prompting further observations.
Kentucky astrophotographer David Joyce captured a detailed image of the Medulla Nebula (CTB 1), a supernova remnant from a star explosion 10,000 years ago, using an 8-inch telescope over seven nights, revealing its colorful and complex structure.
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.
Astronomers discovered a nearly perfect spherical supernova remnant named Teleios deep in the Milky Way, notable for its symmetry and unique radio emissions, likely formed by a supernova explosion in a sparse region of space, offering new insights into stellar death processes.
Astronomers discovered a nearly perfect spherical supernova remnant named Teleios deep in the Milky Way, notable for its symmetry and unique radio emissions, likely due to its location in a sparse region of space that allowed undisturbed expansion, though its exact origin remains uncertain.
Astronomers have discovered a perfectly circular radio object in the Milky Way, dubbed Teleios, which is likely a supernova remnant resulting from a Type Ia supernova. Its precise shape challenges existing theories and offers new insights into cosmic phenomena, with ongoing research needed to determine its exact distance, size, and age.
The Dark Energy Camera (DECam) has captured a 1.3-gigapixel image of the Vela Supernova Remnant, showcasing the remains of a massive star that exploded nearly 11,000 years ago. This colorful image, taken with state-of-the-art technology, reveals the intricate web-like filaments of the expanding nebula, which spans almost 100 light-years. The image also features the Vela Pulsar, the collapsed core of the star, now an ultra-condensed neutron star. DECam's capabilities allow for the creation of mesmerizing images of faint astronomical objects, offering a limitless starscape to explore.
Astronomers from Curtin University and other institutions have discovered a new supernova remnant (SNR) named G321.3-3.9, located 3,300 light years away. The elliptical SNR is estimated to be a few thousand years old and was confirmed using radio and X-ray data. The SNR's distance, diameter, and age were estimated, but uncertainties remain due to limited data. Further observations are planned to search for a pulsar association, which could provide more accurate measurements of the SNR's properties.
