On one of the largest panoramic views of star birth, astronomers using the ultraviolet vision of NASAs Hubble telescope have assembled an image that features approximately 15,000 galaxies, about 12,000 of which are forming stars.

This image is a portion of the GOODS-North field, which is located in the northern constellation Ursa Major, NASA said in a statement Thursday.

The image straddles the gap between the very distant galaxies, which can only be viewed in infrared light, and closer galaxies, which can be seen across a broad spectrum.

The light from distant star-forming regions in remote galaxies started out as ultraviolet, but the expansion of the universe shifted the light into infrared wavelengths.

By comparing images of star formation in the distant and nearby universe, astronomers glean a better understanding of how nearby galaxies grew from small clumps of hot, young stars long ago, NASA said.

Because Earth’s atmosphere filters most ultraviolet light, Hubble can provide some of the most sensitive space-based ultraviolet observations possible. (IANS)

NASA chiefs going back 30 years have come together to mark the space agency’s 60th anniversary.

Five former NASA administrators joined current boss Jim Bridenstine in Orlando on Monday. It was the largest gathering ever of NASA heads and included every administrator since 1989. The conference was arranged by the American Institute of Aeronautics and Astronautics.

The longest-serving administrator, Daniel Goldin of the 1990s, told Bridenstine there’s more to the company than human spaceflight and that the science and technology programs can help draw more public support.

Richard Truly of the post-Challenger shuttle era agreed, but noted humans need to explore.
