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 ...

An international team of astronomers led by Stefan Kimeswenger from the Department of Astro and Particle Physics, together ...

The new models show that after the ejection of the envelope, the stars heat up three times faster than found in older models. This makes it much easier for a low mass star, such as the sun, to form a ...

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 ...

The medium size planetary nebula is the final stage ... mass of our sun is lost by the central star of the Boomerang Nebula in an ejection process called bipolar outflow. The nebula received ...

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 ...

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 ...
