The Hubble Space Telescope has a picture of two galaxies that are home to a lot of star formation. The pair, known together as IC 563 on the bottom right and IC 564 on the top left, are located in the farthest part of the universe. The constellation Sextans is named after the astronomer who used an instrument to measure the position of stars.

The image was captured by two Hubble instruments. The two observations were combined to show the data from both the visible and theIR part of the spectrum.

This new image from NASA’s Hubble Space Telescope looks at two spiral galaxies, collectively known as Arp 303.
This new image from NASA’s Hubble Space Telescope looks at two spiral galaxies, collectively known as Arp 303. The pair, individually called IC 563 (bottom right) and IC 564 (top left), are 275 million light-years away in the direction of the constellation Sextans. The colors red, orange, and green represent infrared wavelengths taken with WFC3, and the color blue represents ACS visible light data. NASA, ESA, K. Larson (STScI), and J.

Hubble scientists wrote that the first used Hubble's Wide Field Camera 3 to study the pair. Galaxies like IC 563 and IC 564 are very bright and host many bright star-forming regions.

The second used Hubble's Advanced Camera for Surveys (ACS) to take quick looks at bright, interesting galaxies across the sky. The observations filled gaps in Hubble's archive and looked for promising candidates that could be studied further.

Clouds of dust and gas form stars in the cold space between stars. The cold temperatures cause the clouds to become clumpy, with a small amount of dust and gas coming together to create knots. The denser part of the cloud collapses when the particles rub against each other, as more and more material is drawn to these knots due to gravity. This is the core of a star.

The gas falls into it and creates more heat. When the temperature reaches thousands of degrees, the protostar starts to glow. It becomes a young T Tauri star, with a disk of matter around it falling into the star over time, while the star also gives off jets. The star becomes a main-sequence star after this stage of expelling material.
