The MeerKAT radio telescope in South Africa has accomplished an extraordinary first. It took some amazing pictures of an extremely distant galaxy jet in the constellation Pisces. This galaxy is roughly 9 billion light-years away from Earth. Cutting-edge radio astronomy is helping us learn about cosmic phenomena hidden from our naked eye right here on Earth! For this, scientists have leveraged MeerKAT’s unique power in combination with a global network of telescopes. As a result, they have taken some of the most detailed images of the universe we have ever seen.
MeerKAT has 64 antennae, or satellite dishes. Each dish is 13.5 meters in diameter and they are spread out in a very large area—up to 8 kilometers—in the Karoo desert region. As Africa’s largest and most powerful radio telescope, MeerKAT is a scientific marvel. Its instantaneous sensitivity outdoes that of a single dish antenna of 100m diameter. This extraordinary instrument is capable of sensing incredibly faint signals from the most distant corners of our universe. As such, it turns into an indispensable resource for astronomers.
Collaborative Efforts in Observing Cosmic Phenomena
The observations done by MeerKAT were only a tiny piece of the puzzle and involved a major collaborative effort between many radio telescopes around the globe. These telescopes from China, Germany, Italy, Latvia, the Netherlands, Poland, South Korea, Spain, Sweden and the United Kingdom worked together with MeerKAT. Combined, they are broadening our cosmic horizons in spectacular ways! For this international collaboration, scientists used the remarkable 25-meter telescope at the Onsala Space Observatory in Sweden. It took advantage of the United Kingdom’s e-Merlin network.
This unparalleled synchronized approach allowed scientists to conduct observations covering features on the scale of thousands of kilometers. Through stitching together the data collected from these different telescopes, scientists were able to produce images with unparalleled detail and clarity. Through this collaborative work, the partners are enriching access to high quality astronomical observations while building global partnerships in ground-breaking scientific research.
Understanding Structure and Dynamics
By collaborating with international observatories, MeerKAT allows scientists to discover more about the detailed structure and dynamics of cosmic jets from galaxies. This unique partnership fuels frontier research in astrophysics. Clear images yield the highest quality scientific results, allowing researchers to better understand the structure of these beautiful jets. These weirdly oriented jets are key to understanding the formation and fate of galaxies.
The knowledge gained through these observations and experiments feed into a greater understanding of how our universe was formed and is constantly evolving. Through observing far-away galaxy jets, researchers can unlock knowledge about the basic, underlying mechanisms that dictate how the universe’s structures form. The data they’ve collected will be invaluable for years to come in supporting continued research and future explorations of the field of astrophysics.
The Path Towards Advanced Astronomy
Though we’re certainly enthused about MeerKAT’s recent triumph, this spectacular observatory has offered far more importance. It is a key partner in the international collaboration effort to construct the Square Kilometre Array (SKA) Observatory. This exciting and ambitious endeavor would design, build, and operate cutting-edge radio telescopes across Australia and South Africa. It will take the field of radio astronomy to new extremes.
The SKA Observatory will be a transformative instrument that will vastly increase what is possible with astronomical research. Enabling scientists to venture into the new frontiers and shadows of our universe. As MeerKAT moves forward, linking its powerful eyes with other telescopes, it will surmountibly stay at the cutting edge of astronomical innovation.
