Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observations of NGC 6334I
We use both chirped-pulse Fourier transform and frequency modulated absorption spectroscopy to study the rotational spectrum of 2-methoxyethanol in several frequency regions ranging from 8.7-500 GHz.

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)

H2CO And CS In Diffuse Clouds: Excitation And Abundance
To provide constraints on the chemical processes responsible for the observed columns of organic species, we used NOEMA to observe the sight line toward NRAO150 in the 2mm spectral window.

Photocleavage Of Aliphatic C–C Bonds In The Interstellar Medium
Ultraviolet (UV) processing in the insterstellar medium (ISM) induces the dehydrogenation of hydrocarbons. Aliphatics, including alkanes, are present in different interstellar environments, being prevalently formed in evolved stars; thus, the […]

Free-Floating Planets, Survivor Planets, Captured Planets and Binary Planets from Stellar Flybys
In star clusters, close stellar encounters can strongly impact the architecture of a planetary system or even destroy it.
