Space Telescopes Image Supernova in M82

by AstroAggregatorMarch 4, 2014

In January a new supernova was spotted in the M82 galaxy – dubbed SN2014J is one of the closest supernovae to occur in the last couple of decades while active observation has been in effect. It is though to be a type Ia Supernova, formed when one of a pair of stars collapses into a white dwarf star which then accumulates material from its partner until enough materials has passed to the dwarf star for it to collapse in on itself – SN2014J is the closest type Ia supernova to occur since SN1972E whose observation forms much of the basis of understanding of type Ia supernovae.

NASA’s Spitzer infrared spectrum telescope took the main image on this article, comparing previous observation from 2005 to recent observations in the early-to-middle part of last month – although SN2014J peaked in intensity around January 31st.

Hubble also managed to get this snapshot of the new supernova, imaging M82 and SN2014J in the visible spectrum proving why Spitzer is such a great instrument with the view of M82 obscured by large wide bands of interstellar dust. Unfortunately this dust reduces the brightness of SN2014J by up to a point of magnitude so further observations are unlikely to be too helpful in defining the behaviour of Type 1a novae – but archive images from Hubble are being searched to see exactly what kind of stars formed SN2014J.

X-ray observatories confirm black hole spinning at nearly the speed of light itself.

by AstroAggregatorFebruary 28, 2013

Yesterday a study was published showing that a black hole in the center of NGC1365 is spinning at near the speed limit of the universe –  but how did this black hole get to spin that fast in only one direction?

Dark Matter filament studied in 3d for the first time

Astronomers using the Hubble telescope have managed to study a giant, 60 million light-year dark matter filament in a distant galaxy cluster MACS J0717. If the mass measured is accurate, then it could account for where a lot of the “missing mass” of dark matter has gone.

New Study accounts for “missing” companion stars in type 1a Supernovae

by AstroAggregatorSeptember 23, 2012

A new theory out of the University of Tokyo has an explanation for why some type 1a supernovae appear to have no companion star – the companion star has, over time, become another white dwarf star that is engulfed by the supernova, leaving no trace of its prior existence.
