Images of M32, a dwarf elliptical galaxy near to our own, show that stars become clustered much more closely together near its centre, which is what should happen if the galaxy contains a black hole.
Looking at a black hole from the outside, it will bend light rays that pass near it, and in this way it will distort images of the sky.
Previously, astronomers have used x-ray telescopes to observe strong winds very near the massive black holes at galactic centers (artist's concept, inset) and infrared wavelengths to detect the vast outflows of cool gas (bluish haze in artist's concept, main image) from such galaxies as a whole, but they've never done so in the same galaxy.
Until recently, it was not clear what prevented the delicate filaments from being destroyed by competing gravitational forces, but Hubble Space Telescope images suggest they are supported by magnetic fields generated near the galaxy's central black hole.
The new images home in on a region around the black hole less than 4.2 light - years across — smaller than the distance between the sun and its nearest star, says Roopesh
An image from W. M. Keck Observatory near infrared data shows that G2 survived its closest approach to the black hole and continues happily on its orbit.
This ultra-powerful field becomes better organized and forms two outwardly directed funnels along the new black hole's rotational axis, which then creates the two bi-polar jets of particles moving near the speed of light that are detected as a short GRB (NASA news release; Seil Collins, New Scientist, April 13, 2011; and Rezzolla et al, 2011; and more discussion and images from Bruno Giacomazzo's presentation).
The position of the supermassive black hole at the center of our Milky Way galaxy, as well as the giant star S2, are shown (inset) in this near - infrared image from the European Southern Observatory's Very Large Telescope in Chile.
Archival Hubble images, taken by the Near Infrared Camera and Multi-Object Spectrometer (NICMOS), support the idea of twin black holes pushing stars away.
