Radiation from the rapidly spinning pulsar PSR B1509-58 makes nearby gas emit X-rays (gold) and illuminates the rest of the nebula, here seen in infrared (blue and red). A neutron star is the collapsed core of a massive supergiant star.
8 Νοε 2024 · neutron star, any of a class of extremely dense, compact stars thought to be composed primarily of neutrons. Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun.
27 Δεκ 2023 · Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity.
24 Μαΐ 2023 · Neutron stars are the remains of the cores of massive stars that have reached the end of their lives. They are one of the two possible evolutionary endpoints of the most massive...
Neutron stars form when a medium-sized star reaches the end of its life and explodes as a supernova, leaving an incredibly dense core behind.
23 Σεπ 2021 · A neutron star is the densest object astronomers can observe directly, crushing half a million times Earth's mass into a sphere about 12 miles across, or similar in size to Manhattan Island, as shown in this illustration.
24 Οκτ 2019 · Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. After such an outburst, the cores of these former stars compact into an ultradense object with...
