A powerful new space observatory called GLAST launched successfully today, and will provide a huge leap in our capabilities to study gamma rays, the highest-energy form of light. The Gamma Ray Large Area Space Telescope will enable scientists to answer persistent questions about a broad range of topics, including supermassive black-holes, pulsars, cosmic rays, and [...]

The supermassive black holes that lurk at the hearts of the most massive galaxies might be spinning faster than astronomers ever thought. In fact, they might be spinning at the very limits predicted by Einstein’s theory of relativity. Perhaps it’s this extreme rotational speed that generates the energetic jets that blast out of the most [...]
Super-neutron stars are possible (UT)

When a star like our Sun dies, it’ll end up as a white dwarf. And if a star contains 1.4 times the mass of the Sun, it’ll have enough gravity to turn into a neutron star. Much bigger stars turn into black holes. But now it turns out, neutron stars can be much more massive [...]
Supermassive black holes shape galaxies (UT)

Astronomers are now understanding the connection between supermassive black holes and the galaxies they inhabit better and better. In fact, it now looks like the powerful winds that blow out of these monsters can have a significant effect on the galaxies they inhabit, helping determine their growth.
In a recent study, published in the journal Nature, [...]
Stranger than black holes (UT)

Black holes are already plenty bizarre. Imagine all the mass of several suns compressed down into an object of potentially infinitely small size. But what if you could find an object that’s even stranger: a theoretical “naked singularity”; a black hole spinning so quickly that it lacks an event horizon. A point in space where [...]
