![Overview of the L1544 (LEFT panel) and IRAS 16293–2422 (RIGHT panel) regions as traced by the Herschel3 continuum maps at 350 𝜇m. The white contours correspond to [5,7,9,12,14]𝜎, where 𝜎 is 12 MJy sr−1 in L1544, and 1.1 MJy sr−1 in IRAS 16293–2422, respectively. The FoVs of the GBT observations are shown as blue circles – solid line for Ku-band and dashed line for X-band observations (see Sect. 3). Green diamonds identify the continuum (∼1.3 mm) peak position in L1544 (Ward-Thompson et al. 1999) and the position of the A/B, and E objects in IRAS 16293–2422 (Kahle et al. 2023). The size of the Herschel beam (25′′) is shown in the bottom left corner, while the scale bar is shown in the bottom right. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Carbon-chain-diversity.png?resize=1200%2C716&ssl=1)
Astrochemical observations have revealed a surprisingly high level of chemical complexity, including long carbon chains, in the earliest stages of Sun-like star formation.

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.

Chemistry Of Complex Organic Molecules In The V883 Ori Disk Revealed By ALMA Band 3 Observations
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary disks remains […]
