1.   Beta and gamma emissions can be detected by scintillation counters.

2.   Because it can detect thermal emissions, Terra can also see volcanoes warming up before they erupt.

3.   In addition, radio astronomers are experimenting with a method to help them detect cosmic emissions even if other services are transmitting in the same band.

4.   Such telescopes could be equipped with instruments sensitive enough to detect infrared emissions characteristic of planets with conditions like those on Earth.

5.   The agent found an expert on thermal imaging who used a device that could detect heat emissions from distant objects that would otherwise be invisible.

6.   The observations, conducted last June, detected ultraviolet emissions from Europa bearing the fingerprint of molecular oxygen, Hall said.

7.   The ultraviolet emissions were detected by another NASA spacecraft, the Transition Region and Coronal Explorer, or Trace.

8.   When the data are fully analyzed, it should be precise enough to detect emissions from a specific urban area, though not from a specific powerplant or factory.

9.   It was the first time such emissions have been detected high in the stratosphere.

10.   The Johns Hopkins telescope could detect ultraviolet emissions from the sulfur and other materials apparently spewing from an erupting volcano on Io.
