One of the most extreme stars in the Milky Way has just gotten even weirder. Scientists have measured the mass of a neutron star named PSR J0952-0607, and found that it is the most massive neutron star ever discovered, registering 2.35 times the mass of the Sun. If true, this is very close to the theorized upper mass limit of about 2.3 solar masses for neutron stars, which is an excellent laboratory for studying these ultra-dense stars at what we think are on the verge of collapse, in hopes of better understanding. strange quantum states of the matter they are made of. “We know roughly how matter behaves at nuclear densities, such as in the nuclei of uranium atoms,” said astrophysicist Alex Filippenko of the University of California, Berkeley. “A neutron star is like one giant core, but when you have one and a half solar masses of this material, which is about 500,000 Earth masses of cores all stuck together, it’s not at all clear how they’re going to behave.” Neutron stars are the col

Have you heard of the LU Camelopardalis, QZ Serpentis, V1007 Herculis and BK Lyncis? No, they weren’t in the boy band in ancient Rome. They are Cataclysmic Variables, binary stars so close together that one star takes matter from its sibling. This causes the pairs to vary greatly in brightness. Could a planet exist in this chaotic environment? Can we see them? A new study says yes to both. Cataclysmic Variables (CVs) experienced a large increase in brightness. All stars vary in brightness to some degree, even our own sun. But the increase in CV brightness is much more pronounced than in stars like our Sun, and it happens on an irregular basis.

A pair of stars orbit each other closely, and one star is larger than the other. The mo
