A NASA observatory has zoomed-in on the Milky Way's galactic big 'sister' and spied 40 X-ray binaries, objects that are believed to be a key factor in the heating of interstellar gases and therefore major drivers of galaxy evolution.
A space telescope designed to look into the furthest-most reaches of space at some of the most energetic phenomena in the known universe has, once again, been turned to face our nearest star.
Astronomers have zoomed into an X-ray emission region immediately surrounding our galaxy's supermassive black hole and stumbled on a mysterious place where stars go to die.
NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
By tracing radioactive material in the remains of a nearby exploded star, scientists have a new understanding of what happened in the star’s final moments. Continue reading →
In a galaxy far, far away, two black holes have been spotted, trapped in a gravitational dance that can only end when they collide and merge as one. Continue reading →
There's small black holes and supermassive black holes, but where are all the medium-sized black holes?
A powerful NASA space telescope has found not one, but 10 monster black holes lurking in the hearts of distant galaxies.
