SPHEREx blink
What is here
Over time
One SPHEREx image per visit, shown in turn: stars stay still, something that moves jumps.
SPHEREx sees infrared light the eye cannot. Each button shows the same spot in another infrared colour; some objects only show in one of them.
What changed between two visits
The last visit minus the first. Still stars cancel out; something that moved leaves a blue spot (where it was) and a red spot (where it is now).
Verdict
What the images say about this spot, and how fast something would have to move for us to notice it.
Measurement
Our number, measured from these images alone, next to what the star catalogue says about the same object.
Spectrum
How bright this spot is in each infrared colour. Every exposure sees it in a different colour, so the exposures together draw the curve.
Brightness over time
Did this spot get brighter or fainter between the visits? Each measurement is divided by this spot's own average brightness at that colour, so a steady source stays near 1.
Small print
For those who want to check: the image on screen, quality flags, the technical numbers, the data release and the sources.
