💥💥A 10 billion-year-old radio signal reaches Earth 💥💥

I’m so excited to share my latest article on new research led by Sydney University astronomers Dr Manisha Caleb and Dr Themiya Nanayakkara, who have announced the detection of an ancient Fast Radio Burst (FRB).

FRBs are incredibly powerful, short-duration blasts of radio waves that last just milliseconds. Nearly two decades after the first FRB was reported, astronomers have found thousands of bursts, yet their origin remains one of astronomy’s biggest mysteries.

These new results shed light on the young host galaxy in the early Universe, providing important clues about the environment where the FRB originated and what might be producing it.

Additionally, the signal encodes an imprint of the matter it encountered during its journey across approx. 80% of the Universe’s history, offering valuable information to help scientists map the structures and distribution of ionised plasma across time.

📡 Beyond citizen science: engineers building the SKA-Low radio telescope in Australia had to rework its antenna layout. The original sunflower-inspired Vogel spiral placed antennas a regular 2.4 m apart, causing destructive interference - a blind spot - at 125 MHz whenever the array looked toward the Milky Way. The fix: a "Perturbed Vogel" pattern.

Here's a rendered concept for the observatory site. The small dishes are replicas of the radio telescope currently connected to the network (build details: https://community.titanobservatory.org/t/demo-1-telescope-hardware-build/85). The larger 10m is the one we still need funding to purchase. Each telescope is powered by a solar array and battery, and connected to the utility shed via fiberoptic to prevent long runs of conductors and allow every telescope to be entirely self-sufficient.

📡 First confirmed radio signal from a single exoplanet! The MeerKAT array caught variable radio bursts from the gas giant Beta Pictoris b (63 light-years away) – an aurora much like Jupiter's. From it, astronomers derived a magnetic field thousands of times stronger than Earth's. Magnetospheres are key to finding habitable worlds.

*** EXCITING NEW ASTRONOMY ***

'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!

📡🌌 THE DESERT CAUGHT THE STARS — THE FIRST RADIO TELESCOPE
September 5
In 1937, Karl Jansky, an engineer at Bell Labs, pointed a homemade antenna at the night sky from the New Jersey countryside and heard it: a steady hiss of static coming not from the stars, but from the very heart of the Milky Way. It was the first time humanity had "heard" the cosmos — the birth of radio astronomy, a new window on the universe that would later reveal pulsars, quasars, and the afterglow of the Big Bang itself.

Years ago I started a project I never finished: making my own radio telescope.

The antenna is done, and I have the steppers and SDR ready, but I wanted to have something more precise, so I am thinking about making my own interferometer.

I have two properties 3km apart, so it could work. I know I have to get a pair of GPSDOs and time observations to the picosecond, but I am a bit lost.

Anyone here with experience in radioastronomy that can help me build this?

Thanks in advance 🙏

Backyard radio astronomy: writing in IEEE Spectrum, David Schneider shows how an RTL-SDR dongle, an LNA and a home-built horn antenna were enough to measure the Doppler shift of the 1420 MHz hydrogen line and plot the Milky Way's rotation curve — the key evidence for dark matter. His results match professional measurements.
