This is a colour composite image of the central region of our Milky Way galaxy, about 26 000 light years from Earth. Giant clouds of gas and dust are shown in blue, as detected by the LABOCA instrument on the Atacama Pathfinder Experiment (APEX) telescope at submillimetre wavelengths (870 micron). The image also contains near-infrared data from the 2MASS project at K-band (in red), H-band (in green), and J-band (in blue). The image shows a region approximately 100 light-years wide.
这是一张银河系中部的彩色复合图像，距地球大约26000光年。巨大的气体云和尘埃以蓝色显示，是用APEX亚毫米望远镜（870微米）的LABOCA 检测到的。图像还包含来自2MASS工程的近红外数据K波段（红色），H波段（绿色)和J波段（蓝色）。该图像显示的区域大约有100光年宽。
Flares from the disk of material surrounding the black hole Sagittarius A*

This series of three images shows an artist’s impression of a bright “blob” of gas in the disk of material surrounding the black hole in the centre of our Galaxy, Sagittarius A*. This blob of material is responsible for the flares detected by the researchers. As the blob orbits the black hole, it is stretched out, and this expansion over time causes the delay between flares being detected at near-infrared wavelengths (with the VLT) and at submillimetre wavelengths (with APEX).
