China's gigantic telescope identifies over 740 pulsars

The Five-hundred-meter Aperture Spherical Radio Telescope, also known as FAST, is located in the Guizhou Province of China, near the city of Pingtang. It is situated in a natural depression surrounded by hills, which helps to minimize radio frequency interference and enhance its performance. FAST is the largest single dish radio telescope in the world.

China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, has identified over 740 pulsars since its launch, the research team has announced.

Pulsars, or fast-spinning neutron stars, originate from the imploded cores of massive dying stars through supernova explosions.

Pulsar observation is an important task for FAST, which can be used to confirm the existence of gravitational radiation and black holes, and help solve many other major questions in physics.

Jiang Peng, chief engineer of the telescope, said the annual observation duration of FAST has exceeded 5,300 hours since it was completed in September 2016, with 30 to 40 terabytes of data received every day. More than 740 pulsars have been discovered so far.

More pulsar discoveries by FAST could help scientists find evidence of gravitational waves, or establish autonomously controlled time reference systems, Jiang added.

Dubbed as the "China Sky Eye," the telescope is located in a naturally deep and round karst depression in the southwestern province of Guizhou. It has a reception area equal to 30 standard football fields.

For the First Time Hubble Directly Measures Mass of a Lone White Dwarf
Baltimore MD (SPX) Feb 03, 2023
Astronomers using NASA's Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf - the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of our Sun. This agrees with earlier theoretical predictions of the white dwarf's mass and corroborates current theories of how white dwarfs evolve as the end product of a typical star's evolution. The unique observation yields insights into theories of ... read more
