New CubeSat will observe the remnants of massive supernovas

Scientists at CU Boulder are developing a satellite about the size of a toaster oven to explore one of the cosmos' most fundamental mysteries: How did radiation from stars punch its way out of the first galaxies to fundamentally ...

ALMA finds possible sign of neutron star in supernova 1987A

Two teams of astronomers have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A. Based on observations of the Atacama Large Millimeter/submillimeter Array (ALMA) and a theoretical follow-up study, ...

Shock waves from stellar explosions take preferential direction

In a paper published in the Astrophysical Journal, a team led by researchers at École Polytechnique have paved the way to unraveling the mystery as to why many supernova remnants that we observe from Earth are axisymmetric ...

The clumpy and lumpy death of a star

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond ...

The Cygnus Loop

The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the detritus of the explosive death of a massive star about ten to twenty thousand years ago. Detailed modeling of its spectacular filamentary shape ...

Exploding stars make key ingredient in sand, glass

We are all, quite literally, made of star dust. Many of the chemicals that compose our planet and our bodies were formed directly by stars. Now, a new study using observations by NASA's Spitzer Space Telescope reports for ...
