Can you spot the differences between the Webb and Hubble images of the same galaxies?

IC 1623 is the red and blue cloud in both images.

This summer, the Webb Space Telescope captured a pair of merged galaxies called IC 1623 A and B (together, only IC 1623). Now, the veteran Hubble Space Telescope has captured a new image of the same pair after taking it for the first time. in 2008. The differences in the two views reflect the different strengths of these telescopes, as one sees the universe primarily in the visible and ultraviolet, while the other sees in the infrared.

The merger of galaxies was first discovered in 1897, and the Hubble and Webb telescopes provide spectacular views of the cosmic dance. The galaxies are located 270 million light years from Earth in the constellation Cetus. Stars in galaxies form about 20 times faster than stars in the Milky Way.

Webb sees mainly infrared and near-infrared wavelengths, which are redder than the reddest visible light. This allows the telescope to see some of the oldest (redshifted) light in the universe, several hundred million years after the Big Bang.

Webb's image of that galaxy was more colorful in red and blue light.

The $10 billion Webb Telescope Launched from French Guiana in December 2021; the precision of the telescope’s launch means the mission’s lifetime could last up to 20 years, a big jump from the original five-year mission plan.

Webb is the latest and greatest, but its predecessor is still working. Hubble was launched in 1990 and has since become one of mankind’s most useful tools for space exploration. The stuttered the antiquated telescope in recent years, but it continues to deliver images primarily in visible and ultraviolet wavelengths, not Webb. That’s why Considered by NASA staff Webb will succeed Hubble rather than replacing it.

As seen by Hubble, dust covers the center of the galaxy.

Images of the galaxy pair from the two telescopes show their respective features. The The system glows in the infrared, making it a target for Webb. Intense merger star formation produces infrared light, but a thick dust lane has obscured many parts of the galaxy from view for years.

Webb could pierce the dust clouds and see more than Hubble could. Its cluster of galaxies—bright red and blue stars—cuts through the dim dust in the Hubble image. The background galaxies are also more pronounced in Webb’s performance.

As Webb’s space exploration continues, he is sure to capture more scenes like the one Hubble first saw in his recent photo. Pillars of creation. Remember that wherever Webb looked, Hubble helped pave the way.
