利用高空气球改进天气数据

ByNASA中文 2022年4月29日2022年4月29日

Researchers at Arizona State University in Tempe are evaluating a small, lightweight, efficient 3D imaging sensor designed for weather forecasting on consecutive balloon flights made possible by NASA’s Flight Opportunities program. Called CubeSounder, the innovation could benefit future balloon flights and CubeSats by enabling state-of-the-art atmospheric sounding capabilities – a process in which sensors probe the sky vertically for details on temperature, moisture, and water vapor, revealing subtle changes in the Earth’s atmosphere. The first of two NASA-supported flight tests for the technology took place in April in Tucson on a Stratollite high-altitude balloon from Tucson-based World View Enterprises. In this image, World View’s Stratollite high-altitude balloon is inflated on the launch pad in Tucson, Arizona on April 9, 2022. Image Credit: World View Enterprises…

太空中的天使之翼

ByNASA中文 2022年4月27日2022年4月27日

This Hubble Space Telescope image features two merging galaxies in the VV-689 system, nicknamed the Angel Wing. Unlike chance alignments of galaxies, which only appear to overlap when viewed from our vantage point on Earth, the two galaxies in VV-689 are in the midst of a collision. The galactic interaction has left the VV-689 system almost completely symmetrical, giving the impression of a vast set of galactic wings. “Zoo Gems,” interesting galaxies from the Galaxy Zoo citizen science project is a crowdsourced program and relies on hundreds of thousands of volunteers to classify galaxies and help astronomers wade through a deluge of data from robotic telescopes. In the process, volunteers discovered a gallery of weird and wonderful galaxy types, some not previously studied. A similar,…

祝哈勃32岁生日快乐！

ByNASA中文 2022年4月22日2022年4月22日

We’re celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called The Hickson Compact Group 40. This eclectic galaxy grouping includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler.
