-
A.
Chandra X-ray Observatory
chosen
The Chandra X-ray Observatory is a space-based telescope that observes high-energy X-ray emissions from hot regions of the universe, such as exploded stars, galaxy clusters, and matter around black holes.
-
B.
Chandra High Resolution Mirror Assembly
The Chandra High Resolution Mirror Assembly is the precision X-ray telescope optics system on NASA’s Chandra X-ray Observatory, designed to focus high-energy X-rays with exceptionally fine angular resolution for astrophysical observations.
-
C.
Einstein Observatory
The Einstein Observatory was NASA’s first fully imaging X-ray telescope in space, pioneering high-resolution X-ray astronomy of cosmic sources.
-
D.
X-ray Timing Instrument
The X-ray Timing Instrument is a high-precision detector system on NASA’s NICER mission designed to measure rapid X-ray brightness variations from neutron stars and other compact objects.
-
E.
Hard X-ray Detector
The Hard X-ray Detector is a space-based instrument designed to observe high-energy X-ray emissions from cosmic sources, enabling studies of phenomena such as black holes, neutron stars, and supernova remnants.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
