The new information comes from the Sloan Digital Sky Survey V, known as SDSS-V. It is part of Data Release 20, or DR20, the latest major collection of information from the project.<\/p>\n\n\n\n

A spectrum is a way of studying light from an object in space. By breaking light into different parts, scientists can learn about an object’s temperature, movement and chemical makeup.<\/p>\n\n\n\n

One of the biggest changes in the new release is that it includes optical observations from the Southern Hemisphere for the first time.<\/p>\n\n\n\n

These observations were made with a telescope at Las Campanas Observatory in Chile.<\/p>\n\n\n\n

They have been combined with observations from the Sloan Foundation Telescope at Apache Point Observatory in New Mexico. <\/p>\n\n\n\n

Together, the two locations allow scientists to study objects in the sky from both the northern and southern parts of Earth.<\/p>\n\n\n\n

The new data include information on about 1.5 million stars. They also contain about 1.1 million spectra from the Black Hole Mapper programme, covering around 500,000 different objects.<\/p>\n\n\n\n

Scientists hope the information will help them better understand supermassive black holes and how they change over time. <\/p>\n\n\n\n

Some of the objects have been observed more than once, allowing researchers to compare their changes.<\/p>\n\n\n\n

The release also combines optical observations with X-ray information from the eROSITA space telescope. <\/p>\n\n\n\n

This gives scientists information about hundreds of thousands of objects that produce X-rays, including active galaxies, galaxy clusters and active stars.<\/p>\n\n\n\n

Another important part of the release focuses on the Milky Way and nearby galaxies. Scientists have mapped areas containing glowing gas, young stars and planetary nebulae.<\/p>\n\n\n\n

The maps include well-known regions such as the Orion and Rosette nebulae.<\/p>\n\n\n\n

The new release also includes 18 scientific catalogues and online tools that make it easier to explore the huge amount of information.<\/p>\n\n\n\n

The data are publicly available, meaning scientists, students, teachers and astronomy enthusiasts around the world can use them. <\/p>\n\n\n\n

Researchers hope the information will lead to new discoveries about how stars and galaxies form and change.<\/p>\n\n\n\n

With DR20, SDSS-V is moving closer to creating a detailed map of the sky across both hemispheres. <\/p>\n\n\n\n

The project is giving scientists a powerful new way to study the Universe and understand its many mysteries.<\/p>\n\n\n\n
