Nasa’s James Webb Space Telescope is a million miles from Earth and has two new targets in sight 🔭🌍 In its first year of operation, Nasa’s billion-dollar telescope will study two hot ‘super-Earths’ for their size and rocky composition.
Rocky, roughly Earth-sized planets that are extremely hot and close to their stars are not uncommon in the Milky Way galaxy. The James Webb Space Telescope is on a mission to study these planets.
‘If it has an atmosphere, [Webb] has the sensitivity and wavelength range to detect it and determine what it is made of,’ Hu added. Brandeker’s team plans to test this hypothesis using NIRCam to measure the heat emitted from the lit side of 55 Cancri e during four different orbits. ‘It turns out that different types of rock have different spectra,’ explained Laura Kreidberg at the Max Planck Institute for Astronomy.
