From 1992–2017, the Australia Telescope Compact Array (ATCA) was used to captured radio imagery of Supernova 1987A. Graduate ...

On May 20, 1990, the Hubble Space Telescope sent its first image to Earth. This photo turned out to be 50% sharper than ...

An artist’s illustration depicts silicon, argon and sulfur releasing from a massive star. - Adam Makarenko/W. M. Keck Observatory Astronomers have observed what they are calling a new type of ...

An illustration of SN2021yfj enveloped in a layer of heavy elements during its supernova explosion W. M. Keck Observatory / Adam Makarenko In September 2021, Steve Schulze, an astrophysicist at ...

Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

When astronomers observe a supernova, they typically see strong indications of light elements like hydrogen and helium. Layers of elements including carbon, oxygen, neon, and magnesium are also ...

This powerful side-by-side comparison shows just how bright a star explosion is. Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images ...

A novel type of supernova, SN2021yfj, has been discovered, exhibiting an unusual spectral signature rich in silicon, sulfur, and argon, unlike typical supernovae which display lighter elements.

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

An international team of scientists, led by Northwestern University astrophysicists, has detected a never-before-seen type of exploding star, or supernova, that is rich with silicon, sulfur and argon.
