Pictured is the supernova of the type Ia star 1994D, in galaxy NGC 4526. The supernova is the bright spot in the lower left corner of the image. Credit: ESA/Hubble More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, […]

A new machine learning algorithm trained only with real data has classified over 2,300 supernovae with over 80% accuracy. Artificial intelligence is classifying real supernova explosions without the traditional use of spectra, thanks to a team of astronomers at the Center for Astrophysics | Harvard & Smithsonian. The complete data sets […]

Cassiopeia A is a supernova remnant in the constellation Cassiopeia. Credit: NASA/CXC/SAO Michigan State University researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as supernovae. This finding also challenges ideas behind how some of […]

Artist’s depiction of the SPRITE CubeSat orbiting Earth. Credit: LASP 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 alter […]

Pictured here is part of the captivating galaxy NGC 2525. Located nearly 70 million light-years from Earth, this galaxy is part of the constellation of Puppis in the southern hemisphere. Together with the Carina and the Vela constellations, it makes up an image of the Argo from ancient greek mythology. […]

The stellar explosion, SN 1987A, located in the Large Magellanic Cloud, was one of the brightest supernovae in more than 400 years. Credit: ESO Discovery of iron-60 and manganese-53 substantiates supernova 2.5 million years ago. When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers […]

ANIMATION A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments. Professor Anton Wallner, a nuclear physicist at ANU, led the study which shows the Earth has been traveling for the last 33,000 years through a cloud of faintly radioactive […]

A team of researchers led by professor Brian Fields hypothesizes that a supernova about 65 light-years away may have contributed to the ozone depletion and subsequent mass extinction of the late Devonian Period, 359 million years ago. Pictured is a simulation of a nearby supernova colliding with and compressing the […]
