Four retired telescopes are helping new astronomers learn about the behavior of dust in galaxies.

Astronomers say that a new exploration of gas and dust around the four galaxies near our Milky Way will provide new insights into the formation of stars.

“These improved images show us that the ‘living things’ in these galaxies are mighty,” said Christopher Clark. In a statement, he leads a team of photographers and astronomers at the Space Science Telescope Institute in Baltimore. Tab) Thursday (June 16).

The observation was guided by data collected from the Herschel Space Observatory of the European Space Agency (ESA), which operated from 2009 to 2013 and obtained a dust signature for long infrared light.

Scientists also incorporated data from ESA’s Planck missions, which ceased functioning in 2013, and NASA’s Infrared Astronomical Satellite and Cosmic Background Explorer, which were in operation in the 1980s and ’90s.

Although all space telescopes eventually stop working due to partial failure or fuel shortages, their data can continue indefinitely, as long as the information is appropriately stored in the archive. Astronomers also revisit those old data to calculate long-term changes in galaxies, black holes, exoplanets, and other curious objects and apply new analytical techniques.

Recent photographs focus on stardust and gas to learn more about how the density of dust clouds can vary between galaxies and within a single universe. Dust builds up as dying stars emit layers of gas, and their path can be altered by pressure waves from exploding stars, continuous gusts from active stars, and the effects of gravity on other objects.

All that dust has a profound effect on the work of astronomers, as it absorbs light from what scientists want to study – about half the starry heavens, according to the statement.

But dust is not always a barrier. Because it contains the heaviest elements, such as those that make up the planets, studying dust can help scientists understand the universe’s origin.
