... 2001 November 8 . Under A Sunspot . Credit: MDI , SOHO Consortium , ESA , NASA . Explanation: At the Sun's surface, sunspots are known to be dark, planet-sized regions of intense magnetic fields. ... The MDI data indicate that immediately under the sunspot a strong inflowing current exists, shown above by the dark arrows. ... Such a configuration appears to divert the normal flow of plasma bubbling up from the solar interior, creating a self-sustaining sunspot . ... About APOD | ...

... Their large amounts of dust make them ideal objects to study how dust forms in the high-redshift interstellar medium (ISM), and to study the interplay between star formation activity, gas and dust. Up until recent interferometric observations with PdBI and ALMA, the full characterisation of SMGs had been hindered by the large beams of single-dish observations that made it challenging to identify their optical and infrared counterparts. ...
