In four years, NASA plans to return astronauts to the Moon as part of Project Artemis. To ensure the success of this endeavor, as well as the creation of a program of sustainable lunar exploration by the end of the decade, NASA has partnered with multiple entities in the commercial space sector. Recently, they announced that contracts will be awarded to 14 additional companies to develop a range of proposed technologies.
Neutron stars are the end-state of massive stars that have spent their fuel and exploded as supernovae. There’s an upper limit to their mass, because a massive enough star won’t become a neutron star; it’ll become a black hole. But finding that upper mass limit, or tipping point, between a star that becomes a black hole and one that becomes a neutron star, is something astronomers are still working on.
Now a new discovery from astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have found the most massive neutron star yet, putting some solid data in place about the so-called tipping point.
