Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesA nearby alien planet is the first of its kind, new observations by the James Webb Space Telescope suggest.

As Raul points out, this planet is unlikely to support life, at least as we understand it, but it could help astronomers study other small exoplanets between the size of Earth and Transmission spectroscopy is based on the fact that elements and the chemicals they make up absorb and emit light at characteristic. When light from a star shines through the atmosphere of a planet, the elements in that atmosphere absorb certain wavelengths, leaving"gaps" in the light spectrum. These gaps are the"fingerprints" of specific elements and molecules in that atmosphere.

"GJ 9827 d is the first planet where we detect an atmosphere rich in heavy molecules like the terrestrial planets of the solar system," Piaulet-Ghorayeb said in the statement."This is a huge step.", Ralf Crawford )in 2017. The exoplanet is located just 5.2 million miles from its host star, GJ 9827, which is around 6% of the distance between Earth and. That proximity means GJ 9827 d completes an orbit in just over six Earth days.
