Did SA MeerKAT telescope just discover an alien planet?

South Africa’s MeerKAT telescope in the Northern Cape has traced the first-ever radio signal directly to a planet beyond our solar system.

The target was Beta Pictoris, a young gas giant roughly 10-times the mass of Jupiter. It orbits about 63 light-years from Earth.

Using 64 interlinked antennas at MeerKAT, researchers from Harvard-Smithsonian’s Center for Astrophysics observed the Beta Pictoris system.

This has occurred on four separate occasions this year, picking up rapid, circular radio bursts at frequencies between 0.85 and 3.5 GHz.

WORLD-FIRST MEERKAT DISCOVERY

This qualifies as a genuinely important moment. MeerKAT sits in the Northern Cape Karoo, operated by the South African Radio Astronomy Observatory under the Department of Science, Technology and Innovation.

Better still, this is homegrown South African infrastructure hosting frontier astrophysics most countries can only dream of …

Moreover, it’s part of something bigger, namely, the Square Kilometre Array. A next-generation telescope project that will eventually dwarf MeerKAT and its current capabilities.

In finding Beta Pictoris, the team of scientists used distant quasars as fixed reference points, allowing them to pin exact emission’s positions and confirm their origin.

WHAT DOES THIS MEAN?

The signal’s signature points to an auroral process called ‘electron cyclotron maser instability.’ That auroral emission lets researchers directly measure an exoplanet’s magnetic field.

Beta Pictoris’s field clocks in at 1.25 kilogauss, or roughly 2 500-times stronger than Earth’s own surface magnetic field. This means it is a planet that spins on its axis once every eight to nine hours.

The findings have yet to be peer-reviewed. But the detection itself is already being treated as an entirely new field of exoplanetary magnetospheric science.

Tracing a radio signal from a plant 63 light-years away and using it to measure that planet’s magnetic field has never been done before in human history.

And it was all possible from MeerKAT, some dishes pointing to the sky in the Northern Karoo scrubland.

An unlikely and seriously proud moment for South Africa …
