Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.
Scientists have been receiving X-ray signals from the Helix Nebula for decades, but now they believe it may hide a horrifying ...
The Helix Nebula is a so-called planetary nebula, which is the late stage of a star that has ejected its outer layers of gas and left behind a dimmer and smaller ember of a star known as a white ...
A planetary nebula is a star in its late stage that has shed its outer layers, leaving behind a small dim star at its center known as a white dwarf, explains the Chandra X-ray Center (CXC ...
"We might have finally found the cause of a mystery that’s lasted over 40 years." Using NASA's Chandra observatory and Europe's XMM-Newton spacecraft, astronomers may have solved a 45-year-old ...
NGC 1514 (also known as Crystal Ball Nebula) is a large and complex elliptical planetary nebula at a distance of about 1,500 ...
A nice catch This week’s first large-scope object is planetary nebula NGC 2867 in Carina the Keel. Sir Patrick Moore included this object in his Caldwell catalog as number 90. You’ll find this ...
ABSTRACT Up to now, 10 planetary nebulae have been regarded as halo planetary nebulae (halo PNe). We obtained low‐ and moderate‐dispersion spectra of the spatially resolved halo planetary nebula H4‐1 ...
Skip to content viewer section. ABSTRACT An increasing amount of the literature reports the detection of magnetic fields in asymptotic giant branch (AGB) stars and in central stars of planetary ...
Using the James Webb Space Telescope (JWST), astronomers have observed enigmatic rings in the planetary nebula NGC 1514, visible in the mid-infrared band. Results of the new observations ...
