![]() It works with caffeine in a synergistic way to calm the body without reducing caffeine alertness.ģ. L-theanine, an amino acid found only in tea, reduces stress and promotes relaxation. There is significantly less caffeine in the average cup of tea - especially when including green and white teas brewed at shorter times and cooler temperatures.Ģ. While the caffeine in tea and coffee are, technically, identical, the experience is different due to three key factors:ġ. It was later shown that the "theine" of tea was identical with the caffeine of coffee, and the term "theine" was then dropped. The International Center for Radio Astronomy Research (ICRAR) is a joint venture between Curtin University and The University of Western Australia.Originally called "theine", caffeine was first discovered in tea in 1827. The MWA celebrates a significant milestone this year as it completes a decade of operations and international scientific discovery. The MWA is a precursor to the world's largest radio astronomy observatory, the Square Kilometer Array, which is under construction in Australia and South Africa. They also hope to discover more of these enigmatic objects in the future, to determine whether they are indeed ultra-long period magnetars, or something even more phenomenal. The research team plans to conduct further observations of the magnetar to learn more about its properties and behavior. Credit: Pawsey Supercomputing Research Centre.

The object has emitted a five-minute pulse of radio wavelength energy for at least the last 33 years. It also raises new questions about the formation and evolution of magnetars and could shed light on the origin of mysterious phenomena such as fast radio bursts.Īn artist’s impression of the ultra-long period magnetar. The discovery has important implications for our understanding of the physics of neutron stars and the behavior of magnetic fields in extreme environments. "Whatever mechanism is behind this is extraordinary." Every 22 minutes, it emits a five-minute pulse of radio wavelength energy, and it's been doing that for at least 33 years. And we're not just talking about a little blip of radio emission. "Assuming it's a magnetar, it shouldn't be possible for this object to produce radio waves. "The object we've discovered is spinning way too slowly to produce radio waves-it's below the death line," Dr. ![]() ![]() Other telescopes followed up to confirm the discovery and learn more about the object's unique characteristics.Īn artist’s impression of the Murchison Widefield Array radio telescope observing the ultra-long period magnetar, 15,000 light-years away from Earth in the Scutum Constellation. It emits bursts of energy that last up to five minutes-five times longer than the first object. They soon found what they were looking for in GPM J1839−10. "So we started searching for similar objects to find out if it was an isolated event or just the tip of the iceberg."īetween July and September 2022, the team scanned the skies using the MWA telescope. Hurley-Walker-O'Doherty's honors supervisor-said the first object took us by surprise. They published a paper in Nature in January 2022 describing an enigmatic transient object that would intermittently appear and disappear, emitting powerful beams of energy three times per hour.ĭr. Initially, scientists could not explain what they had found. The stellar object is only the second of its kind ever detected after the first was discovered by Curtin University undergraduate research student Tyrone O'Doherty.
