KSC-05pd2615

KENNEDY SPACE CENTER, FLA. - At their consoles in the Atlas V Spaceflight Operations Center on Cape Canaveral Air Force Station, members of the New Horizons team take part in a dress rehearsal for the launch scheduled in mid-January. New Horizons carries seven scientific instruments that will characterize the global geology and geomorphology of Pluto and its moon Charon, m...

Ammonia Ice Clouds on Jupiter

The top cloud layer on Jupiter is thought to consist of ammonia ice, but most of that ammonia hides from spectrometers. It does not absorb light in the same way ammonia does.

The most powerful black hole merger ever caught on gravitational waves, and the remnant's event horizon area GREW just like Hawking's area theorem demands. Spacetime itself obeying thermodynamics in real time. 🤯🕳️

Triton Video

NASA Voyager 2 spacecraft flew by Triton, a moon of Neptune, on August 25, 1989. This frame from a video using Voyager data recreates that exciting encounter.

Stellar-mass and supermassive black holes flip on their jets at the EXACT same accretion threshold, ~2% of Eddington. Same physics scaling across 8 orders of magnitude in mass?! The universe really does recycle its tricks. 🤯🕳️

XRISM just clocked quasar H1821+643's black hole winds carrying 100x more energy than we thought 🌀 That's enough feedback power to reshape entire galaxies from the inside out. Mind. Blown.

'Discovery of Two Consecutive Profile Change Events on PSR J0437-4715'

I’m so excited to finally share my second PhD paper!

About a year ago, I discovered something interesting in the closest and brightest millisecond pulsar (MSP) to Earth, PSR J0437-4715.

It appeared there were not one, but two long-term profile change events occurring one after the other. These events are extremely rare in the MSP population. I reported on another one about a year ago.

We used to think these objects were stable over the long term and ran our precision timing experiments on them. However, these new findings are now challenging that idea. New studies are emerging showing that many MSPs have variable profiles.

The exciting thing is that we see only certain parts of the profile affected, along with the polarisations, confirming a magnetospheric origin. What is really fascinating is how similar both events are - it’s like the magnetosphere becomes disrupted but re-organises itself into its original configuration.

Here’s my feature article in #SpaceAustralia with these exciting findings!
