[Title:]
Typical exoplanet system
[Central diagram showing a star with various planets and objects orbiting around it, with trajectories connected by dotted lines and labels and descriptions by solid lines:]
[Label pointing to a large planet with strips and a dot near the center close to the center:]
Giant planet orbiting so close that it's actually rolling on the star's surface
[Label pointing to a small object with several large bulged spots near the star:]
Hot Jupiter
[Label pointing to a small object with strips on side:]
Mini Neptune
[Label pointing to a featureless round planet in the middle distance:]
Planet that could be habitable, if there's a form of life that hates water but loves acid and being on fire
[Label pointing to another object with strips and a dot close to the center:]
Cold Jupiter
[Label inside a bounded curvy area:]
Potentially habitable void
[Label pointing to another planet with dots:]
Hot Mars
[Label pointing to a featureless round planet:]
Planet that may actually be in the habitable zone, according to a very optimistic modeling paper by some desperate postdocs
[Label pointing to a medium-sized object with two sets of spreading out rays coming out. There is also an outline that is slightly dotted:]
There's a pulsar here but it's probably fine
[Label pointing to another small featureless round planet:]
A waterworld paradise with beautiful oceans and warm - wait, no, we just got new measurements, it's a hellish steam oven
[Label pointing to a tiny planet:]
Mini Pluto
[Label pointing to another object:]
Lukewarm Jupiter
[Label pointing to a planet with a line in the middle:]
Planet whose atmosphere is confirmed to contain atoms
[Label pointing to another object which is partly round but some parts are taken off and the parts are shaped like rectangles:]
Earthlike data artifact
[Label pointing to another planet with rings and stripes, but has some small dots near the bottom of the planet and the rings:]
Wet Saturn
[Label pointing to another featureless round object:]
Either a gas giant or a fist-sized rock, depending which calibration method you use
[Label pointing to a bounded area with dots inside:]
Faint dust cloud that will cause several papers to be retracted
[Label pointing to the a dotted line, which is outside:]
Somehow this whole system is smaller than the orbit of Mercury?!
[Label pointing to another object:]
Planet whose surface may host conditions suitable for rocks

Title text:Sure, this exoplanet we discovered may seem hostile to life, but our calculations suggest it's actually in the accretion disc's habitable zone.
