Subaru telescope captures 'halo' of nebula M57

TOKYO, Japan - The National Astronomical Observatory of Japan (NAOJ) released Sept. 17 a picture showing a faint ''halo'' around nebula M57, or the Ring Nebula, some 1,600 light years away from Earth. The Subaru telescope at the summit of Mauna Kea in Hawaii is the first one to successfully capture the halo surrounding the nebula's clear, white outer ring, NAOJ said.

    NASA X-ray Telescopes Reveal the 'Bones' of a Ghostly Cosmic Hand

    NASA X-ray Telescopes Reveal the 'Bones' of a Ghostly Cosmic Hand

    Handout - New composite image showing pulsar wind nebula (referred to as MSH 15-52) resembling a human hand, combining Chandra telescope data (seen in orange (low-energy X-rays), green, and blue (higher-energy X-rays)), while the diffuse purple represents the IXPE X-ray telescope observations. Scientists say they have revealed the "bones" of a ghostly cosmic hand. Two of NASA’s X-ray space telescopes have combined their imaging powers to unveil the magnetic field “bones” of a remarkable hand-shaped structure in space. The space agency says that together these telescopes reveal the behaviour of a dead collapsed star that lives on through plumes of particles of energised matter and antimatter. In 2001, NASA’s Chandra X-ray Observatory first observed the pulsar PSR B1509-58 and revealed that its pulsar wind nebula (referred to as MSH 15-52) resembles a human hand. The pulsar is located at the base of the “palm” of the nebula, while MSH 15-52 is located 16,000 light-years from Earth. Now, NASA’s newest X-ray tele

        James Webb View Of The Ring Nebula

        The NASA/ESA/CSA James Webb Space Telescope has observed the well-known Ring Nebula with unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring Nebula is an archetypal planetary nebula. Also known as M57 and NGC 6720, it is both relatively close to Earth at roughly 2,500 light-years away. This new image provides unprecedented spatial resolution and spectral sensitivity. In particular, Webb’s MIRI (Mid-InfraRed Instrument) reveals particular details in the concentric features in the outer regions of the nebulae’s ring (right). There are some 20,000 dense globules in the nebula, which are rich in molecular hydrogen. In contrast, the inner region shows very hot gas. The main shell contains a thin ring of enhanced emission fromcarbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). Roughly ten concentric arcs located just beyond the outer edge of the main ring. The arcs are thought to originate from the interaction of the central star with a low-mass

Also known as M57 and NGC 6720, it is both relatively close to Earth at roughly 2,500 light-years away. This new image provides unprecedented spatial resolution and spectral sensitivity. For example, the intricate details of the filament structure of the inner ring are particularly visible in this dataset.
