For the first time in history, astronomers have been able to watch as a dying star was reborn as a black hole. It went out with a whimper instead of a bang.
Astronomers have watched as a massive, dying star was likely reborn as a black hole.
Combined observations from three spacecraft show that Jupiter's brightest auroral features recorded to date are powered by both the volcanic moon Io and interaction with the solar wind.
A team of astronomers including Carnegie's Eduardo Bañados and led by Roberto Decarli of the Max Planck Institute for Astronomy has discovered a new kind of galaxy which, although extremely old -- formed less than a billion years after the Big Bang -- creates stars more than a hundred times faster than our own Milky Way.
Online volunteers have helped astronomers at The Australian National University find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.
When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.
A University of Washington-led international team of astronomers has used data gathered by the Kepler Space Telescope to observe and confirm details of the outermost of seven exoplanets or-biting the star TRAPPIST-1.
Monash researchers have identified a new concept -- 'orphan memory' -- which changes the current thinking around gravitational waves.
The surfaces of Earth, Mars, and Titan, Saturn's largest moon, have all been scoured by rivers. Yet despite this similarity and the amazingly Earth-like landscapes of Titan complete with valleys, lakes, and mountains, researchers led by City College of New York geologist Benjamin Black report new evidence that the origins of the topography there and on Mars are different from on Earth.
ALMA has made the first complete millimeter-wavelength image of the ring of dusty debris surrounding the young star Fomalhaut. This remarkably well-defined band of rubble and gas is likely the result of exocomets smashing together near the outer edges of a planetary system 25 light-years from Earth.
