are diffused galaxies a blow to the theory of modified gravity?

Are two galaxies which seem to lack dark matter proof that dark matter must be a particle rather than a quirk of gravity at cosmic scales. Well, it's actually kind of complicated...

how we know the milky way is warped and twisted, and how it got that way

If you imagine galaxies as tranquil clouds of gas and dust, lit up by billions of pinpoints of light, a 3D map of the Milky Way and the details behind it will show you otherwise.

preparing for a very low stakes test of general relativity

A new mission to Mercury will test a quirk of general relativity. It won’t be decisive and will involve a lot of precision measurement and tedious number-crunching. And it’s exactly the kind of science we should be encouraging.

ten billion times stronger than steel: scraping under the surface of a neutron star

Nuclear pasta isn’t exactly an awe-inspiring name, but it may be the strongest substance in the universe and it’s found in only in the crust of neutron stars.
