SPACETRC / DATA WORKBENCH
Beyond the image.
Into the measurement.
Compare sky surveys, read the timestamps of solar products and investigate published gravitational-wave parameters. Each tool keeps its source and scope beside the result.
This page makes no external data connections on opening. Starting a tool connects to its provider. Archives, observations and calculated views are identified separately; missing values are not filled with zero.
CDS / ALADIN LITE
One sky.
Different wavelengths.
Switch between three surveys to inspect the same region in different bands of light. This atlas combines observations from specific survey epochs; it is not a live camera feed.
The atlas engine and survey images load when you start.
Choose a survey and open the scientific sky atlas.
Survey colours map different bands into a visual display. Resolution, coverage and observing epochs differ. Check each survey’s source information before comparing objects or colours.

The face of the Sun.
Geomagnetic change.
The image and Kp are different measurements. The image shows the Sun; Kp is an index representing geomagnetic activity at Earth. This workspace explores source products and does not generate forecasts.

Kp data table and units
Kp is a dimensionless index. NOAA supplies this as an estimated planetary Kp product; it is not a future forecast. The time tag marks the start of a three-hour interval, not an instantaneous sensor reading. Missing intervals are not filled in the chart.
| UTC | Kp | Stations |

SUVI 171 Å is a colour-mapped extreme-ultraviolet product. HMI continuum shows structure in the Sun’s visible surface. The colours of these products do not measure the same physical quantity. Image intervals are read from the source filename; no per-pixel acquisition time is supplied.
LIGO / VIRGO / KAGRA · GWOSC
Choose an event.
Inspect published estimates.
Event parameters belong to a particular analysis version. Read masses, distances and uncertainties beside the source record. This tool is not a live detector stream or a strain waveform analyser.
Events and parameter estimates are requested from GWOSC when you start.

M☉ denotes solar mass; Mpc denotes megaparsec. “Source” masses are in the source frame. Upper and lower error values are retained as published; this page calculates no new uncertainty. GPS seconds and UTC are different time representations.
A RESEARCH ROUTE TO THE SOURCE
Define your question.
Follow the original data.
How does a star’s brightness change with time?
Search by object for light curves, spectra and telescope images. Inspect mission, instrument, observation time and access status in the record.
Open official research interface ↗Source and usage information ↗Which instrument measured a planetary surface?
Follow mission archives for the Moon, Mars and other targets. Read an image, its data product and accompanying documentation together.
Open official research interface ↗Source and usage information ↗Which measurements let me compare two planets?
Follow a planet name and its source publication. Mass, radius and period values may originate in different publications.
Open official research interface ↗Source and usage information ↗Where was a Solar System body at a chosen time?
Choose target, observer and time system in the official calculation interface. A computed position is not a live camera image.
Open official research interface ↗Source and usage information ↗How do you record a research result?
- Write your question and chosen target.
- Record mission, instrument, product identifier, observation date and data version.
- Add the source link, unit, access conditions and uncertainties.
- Distinguish your conclusion from the quantity directly measured by the source.
These cards open the institutions’ original research interfaces. This page does not mirror their full archives or provide unlimited telescope access. Each source’s access conditions apply to its records.
