billion-year-old universe. and this era is known as the dark ages. this is when eventually the first galaxies form, the first storms form. you have to have enough light-collecting capacity, which means a really large mirror, and you have to be looking in the right wavelength regime. unlike hubbell, this is infrared. as space is expanding, it gets stretched out by the same amount that spacex panned while the light was traveling through it. so that means light that left the source as visible light, by the time that reaches us, it s a longer wavelength. infrared. that is so cool. it is going to be so cool. it will be a lot of work for the team on this. i believe i read it is 12-hour shifts, which is going to be around the clock. we will be watching closely to see what happens and what we learn from this.
