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 ...

Image: Hubble's portrait of star's gaseous glow

Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly not algae or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off ...

Conceptual design ready for PLATO telescope simulator

SRON Netherlands Institute for Space Research designs and builds a space simulator to test and calibrate eight out of twenty-six cameras for ESA's next exoplanet hunter telescope, PLATO. The conceptual design is now complete. ...

Total annihilation for supermassive stars

A renegade star exploding in a distant galaxy has forced astronomers to set aside decades of research and focus on a new breed of supernova that can utterly annihilate its parent star—leaving no remnant behind. The signature ...

How astronomers chase new worlds in TESS data

As pink liquid oozed around her shoes, astronomer Johanna Teske started to feel sick. She had been looking for new planets with the Planet Finder Spectrograph, an astronomical instrument resembling an industrial-sized refrigerator ...

Three new Beta Cephei stars detected

Using NASA's prolonged Kepler mission, known as K2, astronomers have identified three new Beta Cephei stars. The newly found trio is an important addition to the still short list of known stars of this type. The finding is ...

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 ...

How many Earth-like planets are around sun-like stars?

A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Knowing the rate that these potentially ...
