Astronomers struggle to explain mysterious short-lived explosions
An international team of astronomers has discovered 72 new transients – bright explosions that fade away far more quickly than a supernova.
Tidal forces kicked stars out of our Milky Way Galaxy
A new study of stars in the Milky Way suggests how our Galaxy’s formation and evolution might have been affected by the tidal pull of other passing galaxies.
Science team creates a cosmic cradle to see how stars are born
A Japanese-led international team of researchers has modelled a star’s birthplace and observed the chemical reactions taking place inside. Their work will shed light on how stars form.
Supermassive black holes control how new stars are born
Astronomers have found a relationship between how stars form in a galaxy and the mass of its central supermassive black hole.
Comet-like planet has an extraordinary orbit too
An international team of researchers led by scientists from the University of Geneva has discovered that an already odd exoplanet is following an extraordinary elliptical orbit.
Researchers find most distant known black hole in the early Universe
A research team from across the world has announced the discovery of the most distant black hole yet. It formed when the Universe was still in its infancy.
Weird supernova breaks all the rules with multiple blasts
A supernova that has exploded multiple times is puzzling astronomers with its drawn-out death throes, challenging accepted physics.
Rosetta’s comet is giving up secrets older than the Solar System
Rosetta’s comet mission is very definitely over, but the information gathered about 67P as it flew alongside is still producing new discoveries for astronomers.
Radio telescopes combine to map far side of our Milky Way Galaxy
Astronomers have used widely separated radio telescopes to measure the distance to a star-forming region on the opposite side of our Galaxy.
Scientists find a surprise final image from comet-chaser Rosetta
A year after it crash-landed onto the comet it had been studying, an unexpected, final, close-up image from Europe’s Rosetta space probe has been discovered by mission scientists.
