Questions in this category have been asked by PJ,MT
- What do you know about WMAP?
- What spacecraft have gone up recently?
- What's the latest, coolest instrumentation?
- what do you know about HST?
- why do we build large telescopes on the ground, if HST has a much better
resolution with just 2.3m?
- If we observed a neutron star in LMC from a X-ray telescope, are we able to use a optical telescope to find out if it has a optical companion?
- How many stars in LMC?
- What's the angular resolution for a X-ray telescope (some early X-ray telescope before Chandra)?
- What's the angular resolution for a typical optical telescope?
- In the field we observed the neutron star, how many stars we would observed in optical?
- What's the typical spectral resolution for a optical telescope?
- What distances can we get to using parallax measurements?
