The companion star in this system has a mass that is 1.174 solar masses (M ⊙), which is significantly lower than that of other known neutron stars with accurately measured masses.

"When I first spotted this system with a very high total mass on our galactic doorstep, I was immediately excited." ...

Galaxies may not be as simple as "young and blue" or "old and red." A new idea from astrophysicist Charles Steinhardt proposes a third type: red star-forming galaxies that break the mold. These galaxi ...

The universe doesn't come with an instruction manual—but if it did, University of Missouri Assistant Professor Charles ...

Barnard’s Star, discovered by American astronomer E.E. Barnard in 1916, is a low-mass red dwarf, one of the most common types of stars. Over the past decade, astronomers have found that many of ...

Scientists have discovered a sub-Neptune exoplanet, GI 410 b, using the radial velocity technique. It orbits a nearby star 39 light years from Earth and has a mass 8.5 times that of our planet. The ...
