NASA has created the first ever map of radioactive material in a supernova remnant, revealing one of the biggest mysteries in the universe: How stars blow up in these explosions, sowing the universe with heavy elements like iron, titanium or gold.

And with "just" I mean 11.4 million years ago, even while Steve Fossey just detected this bright and rare Type Ia supernova using a ‘modest telescope in an unlikely spot: foggy north London.’ Scientists say that it will be visible in the sky soon, as it brightens up. Here you can see the supernova appearing in the sky, in a before an after image of M82, the Cigar Galaxy.

A team of scientists using the European Space Agency’s XMM-Newton space telescope have discovered a weird dead star , which hides one of the strongest magnetic fields in the Universe.

Witness now the death of a star in glorious 3D. It’s not quite as exciting as all that, but astronomers have managed to map the eruptions of the nova using footage from the Hubble telescope. Above are three images of T Pyxidis (that’s T Pyx to its friends), a double star system located some 15,600 light-years away — the white globular bit in the middle is the star. The researchers reported to their surprise that the ejected matter has largely stayed in the area of the star, creating a disk of debris, likely expanding but not leaving the orbit. The findings suggest that the companion in the star system helps dictate where that material goes. More info on the research can be found after the break.
If you’re going to engage in KIRF-ology, you could certainly do worse than HTC’s lovely 5-inch slab of unibody plastic, the Butterfly. But if you want to sell it for $222.00, certain niceties have to go out the window — like the signature 1080p screen, for instance. Star’s slipped a 720p unit in there instead, while also downgrading the RAM to 1GB and swapping out Qualcomm’s 1.5GHz quad-core CPU for a cheaper MediaTek model. The Chinese cloner’s at least kept the other specs real, matching the kosher model’s 8-megapixel rear and 3-megapixel front cameras, dual-sim option, SD card expansion slot and Android 4.2 software. Of course, nothing keeps costs down like not having to pay a designer — and knowing that most of that pesky marketing’s already been done for you.

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.
Most mornings, we wake up with little to no idea what happened the day before, let alone last week. Fortunately, they don’t let us run important scientific research projects. Or maybe they do, and we just forgot? This week (and most others as it goes) we definitely leave it to the pros, as we get some insightful glimpses at some important origins. Ball Lightning, the moon and even us humans are the benefactors of those tireless scientists, who work hard to explain where it all comes from. There’s also a planet with four stars that sees the first few paragraphs of its origin story excitedly written out. One thing we never forget, however, is that this is alt-week.

Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) observatory have observed something very surprising for the very first time: a weird tridimensional spiral structure inside of a dying star, one that is just like our very own Sun. More »
