They saw some features, but follow-up observations with different equipment showed nothing.

Before the end of the month, several observatories obtained follow-up observations.

"But we still need follow-up observations to conclusively prove it."

This was done in order for follow-up observations to be performed by Kepler team members.

These various possibilities are extremely exciting, but a great deal of follow-up observation and modelling needs to be done.

It is also used for follow-up observations of solar system discovered with the Oschin telescope.

After follow-up observations using radial velocity, the planet was confirmed.

Follow-up observations are planned to characterize the nature of the landslide debris.

Interpretation of follow-up observations led to the planet's confirmation.

Follow-up observations from ground-based telescopes also are needed to confirm the discoveries.
