The event horizon of a non-spinning, uncharged black hole can be thought of as a sphere with a radius equal to the Schwarzschild radius, $r_{S}=2 G M / c^{2}$ where $M$ is the mass of the black hole and $c$ is the speed of light. If the black hole at the centre of the Milky Way has a mass of $4.15 \times 10^{6} M_{\odot}$, what is the approximate average density within the event horizon? A: $\sim 1 \mathrm{~kg} \mathrm{~m}^{-3}$ B: $\sim 10^{3} \mathrm{~kg} \mathrm{~m}^{-3}$ C: $\sim 10^{6} \mathrm{~kg} \mathrm{~m}^{-3}$ D: $\sim 10^{9} \mathrm{~kg} \mathrm{~m}^{-3}$

You are participating in an international Astronomy competition and need to solve the following question. This is a multiple choice question (only one correct answer). problem: The event horizon of a non-spinning, uncharged black hole can be thought of as a sphere with a radius equal to the Schwarzschild radius, $r_{S}=2 G M / c^{2}$ where $M$ is the mass of the black hole and $c$ is the speed of light. If the black hole at the centre of the Milky Way has a mass of $4.15 \times 10^{6} M_{\odot}$, what is the approximate average density within the event horizon? A: $\sim 1 \mathrm{~kg} \mathr …

The very first image released by the James Webb Space Telescope (JWST) was of a galaxy cluster called SMACS 0723. The image is considered to be Webb's first deep field, since a long exposure time of 12.5 hours was used to allow the light from very faint and distant galaxies to be seen. The spectrum of one such galaxy is shown in Figure 2. [figure1] Figure 2: Highly redshifted emission lines in the spectrum of a galaxy that is 13.1 billion years old, captured using the JWST's near-infrared spectrometer (NIRSpec).
