... Meet G1.9+0.3, the youngest supernova in the Milky Way that has ever been found. б  This image б is a combination of a radio image from the NRAO?s VLA taken in 1985 and an x-ray image taken from NASA?s Chandra X-ray telescope taken in 2007. ... G1.9 +0.3 is approximately 25,000 light-years away from Earth. б At 140 years old, it should probably hold the title of youngest supernova in our galaxy for quite a long time. Just like all living things stars have a life cycle. ...

To locate it, look along the imaginary line between the two end stars on the leading edge of the PloughтАЩs blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. €а€аAs usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

We investigate the dust associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC) as observed with the Herschel Space Observatory. N49 is unusually bright because of an interaction with a molecular cloud along its eastern edge. We have used PACS and SPIRE to measure the far IR flux densities of the entire SNR and of a bright region on the eastern edge of the SNR where the SNR shock is encountering the molecular cloud. ...

... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky.

... Armagh Observatory, 24th March 2009: The International Space Station ( ISS ) has recently become the second brightest object in the night sky тАФ even brighter than the planet Venus, and second only to the Moon. Evenings will provide the chance of a spectacular view, if the sky is clear, as for the next few days the orbit of the ISS around the Earth repeatedly takes it over Ireland. ... At its best, it is now the second brightest object in the night sky. ...

The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...
