Thousands of distant primordial galaxies of various shapes and sizes glow in infrared light in a newly released image from the Hubble Space Telescope.
the biggest galaxies It’s about 13 billion years old and dates a few hundred million years later the big explosion. By viewing these galaxies in ultraviolet light, scientists can see the chemicals contained within these galaxies — information essential to understanding how galaxies form and evolve. However, there is a problem with this method: this original ultraviolet light is absorbed before it reaches us.
But scientists can look at many, many galaxies that are a little smaller and are 11 billion years old. That’s what astronomers did Hubble Space Telescopewhich helps create this image of a very old and very distant galaxy harvest.

The image is part of a recent survey called UVCANDELS. Over the course of about 10 days from the time of the observation, Hubble photographed about 140,000 galaxies. Some of them can be seen in the newly released image – many types of galaxies viewed from different angles.
UVCANDELS offers “unique insights into ongoing star formation in galaxies both near and far,” said Shen Wang, an astronomer at Caltech, who presented the results June 14 at the American Astronomical Society conference in California.
UVCANDELS is a complement to another scan, CANDELS, which scans infrared and red visible light. Using visible ultraviolet and violet light, Hubble recreated the parts of the sky that Kandels studied, including those in the newly released image known as the Extended Groth Strip. By combining slices from both studies, the scientists created this new image.
These investigations allow scientists a glimpse into the early era of the universe known as reionization. During this era, which ushered in the formation of the first galaxies, the first sources of light began to break through the cosmic veil and ended The Dark Ages of the Universe.„
