The Chandra Space Telescope is a very important instrument, as it can also make observations that other instruments cannot. The visual data he collected is now audible by scientists.

Space is essentially a quiet medium, but not in the recordings NASA shared that day: the agency’s staff turned thousands of data, including images, from different parts of the universe into musical material. The The majority of the recordings were provided by the Chandra Space Telescope, the third member of a constellation called the United States’ Great Observatories.

The collected data was converted into musical material through what is called a sonication procedure. This is a common method and aims to produce a sound from a data set. During this method, brighter spots are accompanied by higher hues, while darker spots are accompanied by deeper and quieter spots. This technology has also been used by NASA for a long time, most recently in the Milky Way, for example. to the map.

The current “concert” differs from its predecessor in that a black hole in the middle of a galaxy called Messier 87 (M87) can also be heard. Messier 87 is a giant elliptical galaxy, the largest and brightest member of the Virgo cluster. Data from the New Mexico Radio Astronomy Observatory has also been used for the sounds produced here.

Another work presents an extremely dense cluster called Westerlund 2, which is a system of very young stars: only one or two million years old, and otherwise about 20,000 light-years away.

The third musical material can be linked to one of the most fascinating astronomical phenomena: this is the supernova Tycho Brahe, discovered in 1572. The supernova is close to us, so when it exploded in 1572, it was the second brightest phenomenon in the night sky for a few months.

Scientists have calculated the maximum length of a Mars mission


Scientists at the University of California say there are a few things to consider before sending a person to Mars to keep the mission as minimal as possible.
