James Clerk Maxwell Telescope discovers flare 10 billion times more powerful than those on the sun

The Hawaii-based James Clerk Maxwell Telescope (JCMT) has discovered a stellar flare 10 billion times more powerful than the Sun's solar flares, a history-making discovery that could unlock decades-old questions about the origin of our own Sun and planets, giving insight into how these celestial bodies were born.

"A discovery of this magnitude could have only happened in Hawaii," said Dr. Steve Mairs, astronomer and lead investigator of the team that discovered the stellar flare. "Using the JCMT, we study the birth of nearby stars as a means of understanding the history of our very own solar system. Observing flares around the youngest stars is new territory and it is giving us key insights into the physical conditions of these systems. This is one of the ways we are working toward answering people's most enduring questions about space, time, and the universe that surrounds us."

The JCMT Transient Survey team recorded the 1,500-year-old flare using the telescope's state-of the art high-frequency radio technology and sophisticated image analysis techniques. Identified by astronomer Dr. Steve Mairs, the original data was obtained using the JCMT's supercooled camera known as "SCUBA-2," which is kept at a frigid -459.5 degrees Fahrenheit.

    Kelvins are Kelvins, not degrees Kelvin.

      "Degrees Kelvin" (K) is a former name for the SI unit of temperature on the thermodynamic (absolute) temperature scale. Since 1967 it has been known simply as the kelvin, with symbol K (without a degree symbol).[1] Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but sometimes the degree Rankine as well.

      Seems like a nitpicky point to make, I can't figure out any reason why saying "degrees kelvin" would make any difference to anyone.

        Oh it totally is nitpicky. Sometimes I can't help myself though.

        Sorry AC.

            If, up until 1967, "2 degrees metre" was proper, and now we just say "2 metres"... then yeah, it would make sense.

            But lets put it another way: saying 'x degrees kelvin' makes as much sense as saying 'y kilomiles'. It's not the fact that it's wrong (it most definitely is), it's that wrong or not, everyone understands the point being conveyed, but the way it's presented strikes the reader as so odd that any discussion becomes about the presentation, not the data.

    is also 0° Kelvin.

    This is totally incorrect. The "degree" is attached to the unit not the value:

    45 to 65 °F not 45° to 65° F
