M74 shines at its brightest in this combined optical/mid-infrared image, featuring data from both the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope. The dust threaded through the arms of the galaxy is coloured red, and the young stars throughout the arms and the nuclear core are picked out in blue, by the James Webb Space Telescope’s Mid-InfraRed Instrument – MIRI. Meanwhile, the Hubble Space Telescope’s Advanced Camera for Surveys adds depth: the glow of the heavier, older stars towards the galaxy’s centre are primarily yellow, combined with the blue in this image to make a spooky green glow. The red bubbles of star formation are also visible in Hubble’s optical wavelengths. Scientists combine data from telescopes operating across the electromagnetic spectrum to truly understand astronomical objects. In this way, data from Hubble and Webb compliment each other to provide a comprehensive view of the spectacular M74 galaxy. Links Image A Image C
(CNN) — Stunning new images produced by the Hubble Telescope and the James Webb Telescope showcase the Phantom Galaxy, a spiral of solar systems 32 million light-years away from Earth.
The galaxy is located in the constellation Pisces, according to the European Space Agency, which collaborates with NASA on both the Hubble Telescope and the James Webb Telescope.
The Phantom Galaxy, formally known as M74, is a kind of spiral galaxy known as a “grand design spiral.” This means that it has well-defined spiral arms, visibly winding out from the center in the newly released images.
The images were created using data from both the Hubble Telescope and the Webb Telescope. Webb detected “delicate filaments of gas and dust” in the galaxy’s spiral arms, according to ESA. The images also provide a clear look at the nuclear star cluster at the galaxy’s center, unclouded by gas.
The Webb telescope also used its Mid-InfraRed Instrument (MIRI) to examine the Phantom Galaxy as part of a project to understand the earliest phases of star formation, ESA noted.
While Webb is best at observing infrared wavelengths of light, Hubble has particularly sharp vision at ultraviolet and visible wavelengths, according to the agency. This allowed it to reveal particularly bright areas of star formation, known as HII regions, in the Phantom Galaxy images.
The combination of data from both telescopes allowed scientists to gain an even deeper understanding of the Phantom Galaxy — and to create spectacular images of the cosmos.
NASA released Webb’s first high-resolution images just weeks ago in July. Bigger than Hubble, the telescope is capable of observing extremely distant galaxies, allowing scientists to learn about early star formation. Hubble orbits Earth, but Webb orbits the sun, around 1 million miles away from Earth.
