Before our Sun was formed, other stars created the heavy elements that make up our planet and are important for the chemistry of life. The investigators will study how this process varies in different parts of our galaxy in order to better understand our cosmic origin. They will use data from a survey of star forming regions in our galaxy obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope. This survey, called ALMAGAL, gives us a better view of how stars are born across our Galaxy. The investigator will expand the reach of this scientific investigation by developing an educational tour entitled Zooming in on Star Formation across the Galaxy and by using the web-based World Wide Telescope (WWT). Incorporating these new data into WWT ensures broad, long-lasting access to the community, and educators can easily incorporate these items into lesson plans. Most stars in the Universe formed in a clustered environment. However, lack of spatial resolution has limited our ability to observe the individual star-forming cores within young star clusters. Understanding the process by which dense proto-clusters fragment into star-forming cores and the role that Galactic environment and evolutionary stages plays is of utmost importance, The investigators seek to develop a predictive theory of star formation that can be applied throughout the cosmos. The ALMAGAL survey will reveal cloud fragmentation on core scales (0.01 pc) across the Galaxy. The ALMAGAL survey, which combines the high angular resolution (1000 AU or better) and large sample size (more than 1000 dense clumps) required to understand proto-cluster fragmentation across Galactic environment and evolutionary stage. The investigator will use this unprecedented sample to measure whether the star formation process varies as a function of Galactic environment or evolutionary stage.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在我们的太阳形成之前，其他恒星创造了构成我们星球的重元素，这些元素对生命的化学成分很重要。研究人员将研究这一过程在银河系不同部分的变化，以便更好地了解我们的宇宙起源。他们将使用阿塔卡马大型毫米/亚毫米阵列（阿尔马）望远镜对银河系中星星形成区域进行调查的数据。 这项名为ALMAGAL的调查让我们更好地了解恒星是如何在银河系中诞生的。调查员将扩大这项科学调查的范围，开发一个题为“放大整个银河系的星星形成”的教育旅游，并使用基于网络的万维网望远镜。 将这些新数据存储到WWT中可以确保社区能够广泛、持久地访问这些数据，教育工作者可以轻松地将这些数据纳入课程计划。宇宙中的大多数恒星都是在集群环境中形成的。然而，缺乏空间分辨率限制了我们观察年轻星星团中单个恒星形成核心的能力。了解致密的原星团分裂成恒星形成核心的过程以及银河系环境和演化阶段所起的作用至关重要，研究人员试图发展一种可应用于整个宇宙的星星形成的预测理论。ALMAGAL调查将揭示整个银河系核心尺度（0.01 pc）的云碎片。ALMAGAL巡天结合了高角分辨率（1000 Au或更高）和大样本量（超过1000个致密团块），这是了解银河系环境和演化阶段中原星系团碎片化所必需的。研究人员将使用这一前所未有的样本来衡量星星的形成过程是否会随着银河系环境或进化阶段的变化而变化。这一奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
