Best of both worlds: Asteroids and massive mergers

The race is on. Since the construction of technology able to detect the ripples in space and time triggered by collisions from massive objects in the universe, astronomers around the world have been searching for the bursts ...

Automated observing network inaugurated at SOAR telescope

Supernovae, neutron star mergers, black holes at the center of galaxies, erupting young stars—these are all examples of objects in the night sky that change their brightness over time. In the coming years, astronomers expect ...

Astronomers reveal true colors of evolving galactic beasts

Astronomers have identified a rare moment in the life of some of the universe's most energetic objects. Quasars were first observed 60 years ago, but their origins still remain a mystery. Now researchers at Durham University, ...

Image: Hubble traces a galaxy's outer reaches

Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way. But how could that be? 

An asteroid just buzzed past Earth, and we barely noticed in time

A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, Australian time. It was discovered by the Brazilian SONEAR survey just days ago, and its presence was announced mere hours before it zoomed past our planet. ...

Holes in the Universe sharpen cosmic measurements

Regions of the Universe containing very few or no galaxies—known as voids—can help measure cosmic expansion with much greater precision than before, according to new research.
