The Mystery Of Homochirality On Earth
Homochirality is an obvious feature of life on Earth. On the other hand, extraterrestrial samples contain largely racemic compounds. The same is true for any common organic synthesis.

The Mystery Of The Fullerenes In Space Explained
Fullerenes are carbon molecules which are very big, complex, and highly resistant, Their atoms are organized in three dimensional spherical structures, with a pattern of alternating hexagons and pentagons, shaped […]
![Integrated intensity maps of a selected transition for each O-bearing COM. The upper right panel in each figure shows the spectra toward the center and the filled regions indicate the integration ranges for the zero-order moment maps, which is 3.5 − 10.7 km s−1 , except for CH3OH with 3.5 − 12.0 km s−1 , for the zero-order moment maps. The blue contours in the top-left panel represent the ALMA 1.3 mm continuum emission (Tobin et al. 2018) with levels of [3, 5, 7, 10, 30, 70]-𝜎. The horizontal grey line in the top left panel shows the PV cut used in Figure 7. The blue pixel at the top right panel indicate the pixel that is used to extract the spectra in this work. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/03/PRODIGEEnvelope-To-Disk.png?resize=1200%2C718&ssl=1)
