HH 46/47
An embedded protostellar pair driving a clumpy bipolar flow across roughly ten light-years.
Also known as HH46/47, HH 46, HH 47, Herbig-Haro 46/47.
Catalog
Position basis, the same label the app shows on the selection card.
Every aspect, with its origin
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Hubble proper motions
The bright jet emerges 37.5° from the sky plane at an average 300 km/s; shock ages range from decades to about 1,300 years.

UncertaintyJet inclination ±2.5°; individual working-surface clumps differ by roughly ±40 km/s.
LimitThe source changes direction by about 15° over time; this renderer preserves one measured mean axis rather than predicting that history.
Webb near-infrared protostellar pair and lobes
Webb resolves the embedded stars, orange ejections, blue filaments, and wide outflow cavities in near-infrared light.

Disk rendering
The close-up wraps the JWST NIRCam image (1.15–4.44 μm near-infrared composite) on a disk tilted to the published inclination and position angle, with 13,000 particles sampled from its ring profile.
LimitVertical structure and the far side of the disk are not resolved by the image; scale height is a display choice.

What is not measured
- Appearance: a reconstruction from measurements, not a direct observation. Disk rendering. Vertical structure and the far side of the disk are not resolved by the image; scale height is a display choice.
Not yet documented
- Physical data: no record. Space Time does not claim a source for this aspect.
