Fireworks, in space.

Or:
a peek behind the scenes of big camera with flash photographs that could be in space. But are really on earth (sorry to destroy the illusion that I don’t actually have a space ship with time travel!) This is wandering through a nature reserve that was once a farm.

The rare metal #terbium has been found in an #exoplanet’s #atmosphere for the first time. The researchers at Lund University in Sweden have also developed a new method for analyzing #exoplanets, making it possible to study them in more detail.

The TRAPPIST-1 system, with its ultra-cool red dwarf star and 7 exoplanets is relatively small in extent, as illustrated by this graphic of the orbits of the exoplanets compared to that of planet Mercury.

Here is a graph from the paper that shows how the measured temp. of 503K implies a lack of atmosphere for exoplanet TRAPPIST-1b.
Top green curve: flux for 508K temp predicted for zero heat redistribution.
Blue curve: flux for measured 503K dayside temp.
Orange curve: the predicted flux with heat redistribution by an atmosphere.
Last 2 curves: spectra from CO2 and O2+CO2 atmospheres.
The MIRI 15 µm filter measurement lies on the blue curve.

An artist's concept of a view from the watery surface of exoplanet TRAPPIST-1f.
Measurements by Hubble of UV radiation in the TRAPPIST-1 system suggest that the outer planets of the system might still harbor substantial amounts of water.

#Congratulations to my student, David Specht, now Dr David Specht, following his #PhDViva today. David's #thesis included the development of the most accurate and best tested model of #gravitational #microlensing in our #Galaxy, as well as modelling of the first #discovery from #space of an #exoplanet detected by the microlensing effect. I'm one proud #supervisor.
