Can a mid-infra red view reveal the universe's secrets? In this month's Naked Astronomy, we meet MIRI, the Mid Infra Red Instrument set to launch on the James Webb Space Telescope. It should give us a glimpse of the very first galaxies and examine the clouds of hydrogen gas spread throughout the universe. We'll also find out how distorted galaxies can shed light on the distribution of dark matter, discover El Gordo - a newly discovered galaxy cluster.
