Astronomy news this week: Hubble images the most distant star, radio telescopes combine forces to probe black hole jet, and neutron star hotspots explained.
Our Galaxy's Center Might Hold Thousands of Black Holes
A new study has uncovered a dozen stellar-mass black holes within 3 light-years of the supermassive black hole at our galaxy’s core — and these might be just the tip of the iceberg.
James Webb Telescope Delayed Until 2020
NASA officials announced Wednesday that the James Webb Space Telescope launch would be delayed until approximately May 2020. But before the mission can launch, its managers may have to face Congress.
