Final answer:
OPTION A AND B.
Hannah can use star maps and apps on her smartphone or tablet to find and identify constellations, or a planisphere for physical charts. Virtual reality headsets for immersive sky simulation and weather forecasting apps for stargazing planning might also be helpful.
Step-by-step explanation:
Hannah can utilize various technological applications to find and identify constellations. Star maps and apps for smartphones and tablets are excellent tools for this purpose. Many astronomy apps are available that provide interactive star charts and allow users to point their phones at the sky to identify celestial objects. These apps often come at a low cost or even free. Additionally, planispheres are physical sky charts that can help Hannah to locate constellations based on her latitude and date. For those who prefer the do-it-yourself route, there are online templates available to construct a planisphere.
For a more immersive experience, virtual reality headsets can offer simulated views of the night sky, including constellations. Although not directly related to star-gazing, some weather forecasting apps might help to predict clear skies, which is useful for planning a stargazing session. While social media platforms may not have direct functionality in star identification, they can be sources of community advice and shared experiences from other astronomy enthusiasts.
