A Prime Suspect for Dark Matter Might Be Escaping From Neutron Stars

A Prime Suspect for Dark Matter Might Be Escaping From Neutron Stars

After axions were first theorized by physicists in the suburbs of Chicago 45 years ago, they quickly became a robust candidate for explaining dark matter. All this time, though, the ultra-small particles have remained hypothetical. Now, a team of astrophysicists have proposed that axions may be responsible for an excess of X-ray emissions seen coming from a group of neutron stars in our galaxy.

The stars dubbed the “Magnificent Seven” are neutron stars that emit low-frequency X-ray radiation from their surfaces. Neutron stars are the extremely dense afterlives of collapsed stars. They possess powerful magnetic fields, and, as their name would suggest, are constituted in large part by neutrons. The new research, published this week in the journal Physical Review Letters, focuses on a yet-unexplained bunch of high-frequency X-rays th ....

Hand or face: NASA wonders as it shares breathtaking photo of a neutron star

Highlights
NASA shares stunning photo of a spinning neutron star surrounded by a cloud of energetic particles on Instagram.
When it was shared in 2009 several people said they saw a hand-like shape in the X-ray emission, while some saw a face in WISE s infrared data.
The American space agency asked the netizens to help solve the dispute.
New Delhi: The National Aeronautics and Space Administration recently shared a stunning photo of a spinning neutron star surrounded by a cloud of energetic particles on its social media page.
The image is of the star named PSR B1509-58 which is about 17,000 light-years from Earth and was taken in 2009 by ....

Our Galaxy Has a Shocking Array of Really Weird Stars. Here's Your Ultimate Guide

2 JANUARY 2021
You know how stars do. They re out there, doing their thing, fusing a whole bunch of hydrogen into helium, shining up the joint.
But some stars are just a little bit different from the norm. Not content with simply lighting up the night sky like a giant disco, they zoom, shimmer, dim and even hang around seeming to be older than the actual Universe. These are our galaxy s oddballs, and we love each and every one.

Need for speed: PSR J0002+6216
(J. English/University of Manitoba/NRAO/F. Schinzel et al./DRAO/Canadian Galactic Plane Survey/NASA/IRAS)
We re not sure where the star named PSR J0002+6216 is headed, but we know it s heading there fast. It s travelling at the absolutely breakneck speed of 1,130 kilometres per second (700 miles per second). That could take it from Earth to the Moon in six minutes. ....
