... 2002 August 1 . Sunspots and Solar Active Regions . ... Explanation: July was a good month for sunspots ... really big sunspots. ... While individual sunspots are not numbered or cataloged, groups of sunspots, designated solar active regions, are given consecutive numbers as they appear on the visible solar disk .

... To help choose between these competing hypotheses, the nearby Seyfert II galaxy NGC 4388 has been observed in X-ray light recently by many recent Earth-orbiting X-ray observatories, including CGRO , SIGMA , BeppoSAX , INTEGRAL , Chandra , and XMM-Newton . ... The constant flux and apparent absorption of very specific X-ray colors by cool iron together give evidence that the central black hole in NGC 4388 is seen through a thick torus composed of molecular gas and dust . ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... 2 April 1999 . The Nobeyama Radioheliograph data show that in the microwave range, besides large-scale trans-equatorial chains (see, e.g., the May 11-15, 1993 and November 1-4, 1993 events), there are also many examples displaying large and strongly evolving "longitudinal" or "internal" chains connecting remote active regions inside an active zone in one (northern or southern) hemisphere (the August 20-September 3, 1998 event). ...

... For us to see them from such great distances, quasars must be producing enormous energy -- they are about 1000 times brighter than an average galaxy! ... One of their choices for the energy source of quasars was a black hole. ... On the one hand, it may seem difficult to think that mere friction between bits of matter could account for the energy of a quasar, but, on the other hand, gravity is unimaginably strong near a black hole. ... How does matter actually rush towards the black hole? ...

. The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) is providing integral field spectroscopy on ~140 nearby active galaxies in the wavelength region 3300-7000 Angstroms at resolutions as high as 7000. In this talk, I present the first results of this survey. I show how, by combining data analysis with detailed photoionisation and shock modelling, we are gaining a new understanding of the physics of both Seyfert and LINER galaxies.
