Hubble sets sights on an explosive galaxy

When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous—so ...

NICER's night moves trace the X-ray sky

In this image, numerous sweeping arcs seem to congregate at various bright regions. You may wonder: What is being shown? Air traffic routes? Information moving around the global internet? Magnetic fields looping across active ...

Subaru Telescope captures 1800 new supernovae

Astronomers using the Subaru Telescope identified about 1800 new supernovae in the distant universe, including 58 Type Ia supernovae over 8 billion light-years away. These findings will help elucidate the expansion of the ...

Explosions of universe's first stars spewed powerful jets

Several hundred million years after the Big Bang, the very first stars flared into the universe as massively bright accumulations of hydrogen and helium gas. Within the cores of these first stars, extreme, thermonuclear reactions ...

Could this rare supernova resolve a longstanding origin debate?

Detection of a supernova with an unusual chemical signature by a team of astronomers led by Carnegie's Juna Kollmeier—and including Carnegie's Nidia Morrell, Anthony Piro, Mark Phillips, and Josh Simon—may hold the key ...

Waiting for neutrinos

On Feb. 24, 1987, light from a supernova that exploded 168,000 years ago in the Large Magellanic Cloud, a neighbor of the Milky Way, reached Earth. Astronomers Ian Shelton and Oscar Duhalde at the Las Campanas Observatory ...

Modeling the origin story of the elements

More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright "guest star" in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times scattered ...
