- Said Erik Blaufuss (right) of the finding, It's a pretty event--let's send it out there. This was then 8:09 PM their time at the University of Maryland. This was a public notice over one of astronomy's heads-up networks about this particle, now called Ice Cube-170922A. The hope was that some astronomer would see this info and look at the same area of the sky from where came the neutrino. Maybe they'll find the galaxy or whatever responsible for this neutrino.
- Mind you, not only are there these neutrinos, but since 2015, other sensitive instruments which can detect rolling waves of gravity were also built. Finding both neutrinos and gravity waves at the same time is a very recent development called multimessage astronomy.
- Keep in mind that astronomers heretofore have only looked at light, which is an electromagnetic wave, terrible, because it can get reflected, absorbed and misdirected, obscuring source information. Now, with neutrinos and gravitational waves they have two different kinds of pure messages coming at the speed of light. Nothing stops them or gets in the way. And they specifically come from colliding black holes or collapsing supernovae or neutron stars that previously were largely invisible.
- So, four days after Blaufuss sent out the IceCube notice,
- Two days later, on September 28, at 6:10 AM:
- Sarah Buson of the Fermi team from NASA's Goddard Space Flight Center said it was very exciting:
- That same day, scientists on a survey called ASAS-SN (yes, pronounced assassin), operating at optical wavelengths (which we can see with our own eyes), announced that this spot had been brightening over the past 50 days and the brightest it had seen in several years.
- On September 29, the next day, at 9 AM, another optical telescope found that spot to be a blazar, a supermassive black hole at the center of a galaxy, where matter falling into it results in jets of ionized matter aimed straight at us.
- On October 17, the Very Large Array in New Mexico, operating at radio wavelengths confirmed the light was coming from a blazar's jet.
- This spot, now known as the Texas source, was the first where a high-energy neutrino coincided in space and time with a high-energy gamma ray photon.
- Francis Halzen (right), principle investigator for IceCube made the observation that over the whole sky, the number of high-energy neutrinos and the number of gamma-ray photos are roughly the same, so the obvious thing is that they are coming from the same sources.
- As an aside, the first non-light messenger, in February of 1987, came from Supernova 1987A, a dying star whose core collapsed and exploded, for 25 neutrinos in Japan, the U.S. and Russia were detected. Three hours later, optical light came from that shock wave. By November x- and gamma- rays arrived from new heavy elements created in the explosion. The Texas source, thirty years later, was only the second such event.
For some, if not many, what a waste of tax dollars. No food is being placed on their table.

Tiger Woods' blasted a drive here in 2002 that went 498 yards. But back to my 17th, I should add that the wind helped, and, so too, perhaps, the concrete cart path. That white spec next to my golf cart is my ball just short of the 100 yard marker. At tee-off, my golf watch read 356 yards.
