These Dwarf Galaxies Seem to Be Devoid of Dark Matter, And It Doesn't Make Sense

These Dwarf Galaxies Seem to Be Devoid of Dark Matter, And It Doesn’t Make Sense

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious ‘stuff’ permeates the universe. In particular, it exists in halos surrounding most galaxies.   The mass of the halo exerts a strong gravitational influence on the galaxy itself, as well as on others in the neighborhood. That’s …

New Model Helps Unravel Complex Psychiatric Disorders Such As Autism and Schizophrenia

The research focuses on mapping cis-regulatory components in human neurons that may be connected to the heredity of psychiatric disorders. A Mount Sinai stem cell model may be able to shed light on the complex biology behind certain psychiatric disorders. In order to map disease risk variants in human neurons, researchers from the Icahn School of …

Improved model for the mass distribution of galaxy cluster SMACS J0723.3−7327 based on Webb telescope image

This JWST image shows the galaxy cluster SMACS J0723.3−7327 with a large number of lensed background galaxies. The white bar at the bottom corresponds to 50 arcsec, which is approximately the maximum size of Jupiter observed from Earth. Credit: NASA, ESA, CSA and STScI Using the first science image released by the James Webb Space …
