Neutron Star’s Magnetism Measured for the First Time

Image credit: ESA Using the space-based XMM-Newton X-Ray observatory astronomers with the European Space Agency have made the first direct measurement of a neutron star’s magnetic field. A neutron star is a very dense object with the mass of a large star packed into a radius of only 20-30 km, and they were predicted to …

Survey Finds 1000 Variable Stars in Nearby Galaxy

Image credit: ESO An international survey by the European Southern Observatory has uncovered more than 1000 luminous red variable stars in nearby galaxy Centaurus A (aka NGC 5128). This is the first survey that’s ever been performed on a galaxy outside our own Milky Way. These stars, known as Mira-variables, pulse in a very specific …

Astronomers Find a Supernova Factory

Image credit: NRAO Using the National Science Foundation’s Very Long Baseline Array (VLBA), astronomers have discovered a recently exploded supernova 140 million light years from Earth. The supernova is in a region where two galaxies are colliding together, and furiously forming new stars. The astronomers consider this super star cluster region a “supernova factory” because …
