Description
Data from the newly commissioned Transiting Exoplanet Survey Satellite
has revealed a “hot Earth” around LHS 3844, an M dwarf
located 15 pc away. The planet has a radius of 1.303+/- 0.022 R
⊕ and orbits the star every 11 hr. Although the
existence of an atmosphere around such a strongly irradiated planet is
questionable, the star is bright enough (I = 11.9, K = 9.1) for this
possibility to be investigated with transit and occultation
spectroscopy. The star’s brightness and the planet’s short
period will also facilitate the measurement of the planet’s mass
through Doppler spectroscopy.

Exoplanets and Astrobiology
The search for life in the universe has been driven by recent discoveries of planets around other stars (known as exoplanets), becoming one of the most active fields in modern astrophysics. The growing number of new exoplanets discovered in recent years and the recent advance on the study of their atmospheres are not only providing new valuable
