Using the Hubble Space Telescope (HST), astronomers have investigated the stellar population of the globular cluster NGC 1835. They detected a remarkably extended horizontal branch in this system. The discovery, reported ...
An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their ...
This image from the NASA/ESA Hubble Space Telescope is teeming with color and activity. It features a relatively close star-forming region known as IRAS 16562-3959, which lies within the Milky Way about 5,900 light-years ...
