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.

These proposals are part of NASA’s fifth competitive Tipping Point solicitation, one of many private-public partnership programs overseen by NASA’s Space Technology Mission Directorate (STMD). For this latest solicitation, Tipping Point is awarding contracts with a combined value of over $370 million for technology demonstrations that will facilitate future lunar missions and commercial space capabilities.

The Most Massive Neutron Star has been Found. It’s ALMOST the Most Massive Neutron Star That’s Even Possible

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.
