... 2004 July 26 . A Large Active Region Crosses the Sun . ... Explanation: An unexpectedly large sunspot region is now crossing the Sun. The active region is home to rivers of hot plasma , explosive flares , strong magnetic fields , a powerful Coronal Mass Ejection (CME), and a sunspot group so large it can be seen by the protected eye without magnification. In fact, this region appears larger than Venus did when it crossed the Sun last month. ... About APOD | ...

... 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). ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...

Black holes . ... Black holes are objects for which the gravitational attraction is so strong that nothing, not even light, can escape from it. ... The material inside a black hole is concentrated into a singularity: a single point of infinitely high density where space and time are infinitely distorted. ... The existence of such black holes has been inferred in cases where the black hole pulls gas of a companion star that orbits around it. ... Gravity's Fatal Atraction: Black Holes in The Universe. ...

... Research . ... A rare hybrid morphology radio galaxy . ... In this project we will be able to investigate the environmental effect on star formation and galaxy evolution in individual galaxies falling into the cluster through radio observations of active galactic nuclei (AGN). Current models of galaxy evolution regulate the star formation rates within the simulated galaxies by invoking radio-mode feedback from AGN. ... Julie.Banfield@anu.edu.au . ...
