## This is a Webb image

**NGC 2392 (Lion Nebula)**

Formerly known as: Eskimo Nebula

Webb sees infrared, which is heat rather than light your eye can detect, so there was no colour here to photograph. Each colour in this picture stands for one of the wavelengths Webb recorded, which is how invisible light is made visible.

What each colour stands for

A micrometre (µm) is a thousandth of a millimetre. Your eye stops seeing at about 0.7, so every wavelength below is beyond it.

- Blue: 1.15 µm (NIRCam)
- Cyan: 1.87 µm (NIRCam)
- Yellow: 2.12 µm (NIRCam)
- Orange: 3.35 µm (NIRCam)
- Red: 10 µm (MIRI)

Released: 2026-08-10

## This is a plan, not a live feed

No public source reports where Webb is actually pointing right now. What you see below is the schedule STScI published in advance. Some of it will not happen: targets of opportunity, such as a sudden supernova, can push planned observations aside at short notice.

STScI states, on the schedule page itself:

> Since the schedules do not take into account unforeseen events, including some target of opportunity observations, it is possible that the actual executed observations will differ from those planned.

All times are UTC, the single clock observatories share worldwide. They are planned start times and typically shift by up to an hour.

## Data and updates

The page loads this week's observing schedule as STScI published it, with the source file of every fact. The schedule changes every week, so this markdown version lists none of its entries.
