Powerful Black-Hole Wind Ruffles Spiral Galaxy

A huge, windy swirl of gas — usually found in the largest, most active galaxies — commands the center of a spiral similar to the Milky Way and may disrupt the galaxy’s star formation process, new research shows.

The galaxy, spotted by the European Space Agency’s (ESA) XMM-Newton satellite telescope observatory, is, like the Milky Way, a spiral with a supermassive black hole at the center. But its center’s ability to produce new stars is compromised due to a fierce wind coming from that black hole as it swallows up its surroundings, ESA officials said in a statement. The gases and winds swirl around the black hole at about 10 percent of the speed of light, the statement said. Continue reading Powerful Black-Hole Wind Ruffles Spiral Galaxy

The last waltz

This curious galaxy — only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340 — has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged with another galaxy leaving a fine mist, made of millions of stars, spewing from it in long trails. Continue reading The last waltz

Lost in space. New Hubble image of galaxy NGC 6503

Although the Universe may seem spacious most galaxies are clumped together in groups or clusters and a neighbour is never far away. But this galaxy, known as NGC 6503, has found itself in a lonely position, shown here at the edge of a strangely empty patch of space called the Local Void. This new NASA/ESA Hubble Space Telescope image shows a very rich set of colours, adding to the detail seen in previous images. Continue reading Lost in space. New Hubble image of galaxy NGC 6503
