Physicists observe long-expected helium superfluid phase
Physicists have reported that they have finally observed helium 3 existing in a long-predicted type of superfluid, called the ß phase. This is an important discovery, if it’s borne out, for reasons that partly have to do with its isotope, helium 4. … Continue reading

Onto drafting the gravitational history of the universe
It’s finally happening. As the world turns, as our little lives wear on, gravitational wave detectors quietly eavesdrop on secrets whispered by colliding blackholes and neutron stars in distant reaches of the cosmos, no big deal. It’s going to be … Continue reading

Awk CZTI result from Crab pulsar
An instrument onboard the ISRO Astrosat space-telescope has studied how X-rays being emitted by the Crab pulsar are being polarised, and how such polarisation varies from one pulse to the next. This is very important information for understanding how pulsars … Continue reading

Neutron stars
When the hype for the announcement of the previous GW detection was ramping up, I had a feeling LIGO was about to announce the detection of a neutron-star collision. It wasn’t to be – but in my excitement, I’d written … Continue reading

The secrets of how planets form
Astronomers who were measuring the length of one day on an exoplanet for the first time were in for a surprise: it was shorter than any planet’s in the Solar System. Beta Pictoris b, orbiting the star Beta Pictoris, has … Continue reading
