While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. "Intermediate-mass black holes contain...

Where do stars form when galaxies collide? To help find out, astronomers imaged the nearby galaxy merger NGC 2623 in high resolution with the Hubble Space Telescope in 2007. Analysis of this Hubble image and images of NGC 2623 in infrared light by the Spitzer Space Telescope, in X-ray light by XMM-Newton, and in ultraviolet [...]

But finding remains a challenge."The new study used the European Space Agency's orbiting XMM-Newton observatory to observe the candidate, called NGC 5408 X-1, in 2006 and then again in 2008. It found further proof that the signal is a medium-sized black hole.Black holes are objects that trap matter and even light with their gravity. Though astronomers can't see them directly, they detect...
