The NASA/ESA Hubble Space Telescope and NASA/ESA/CSA James Webb Space Telescope have teamed up to capture complementary views of a star-forming region known as the Cat’s Head Nebula 🐱
It is seen here from the perspective of Webb’s #MIRI (first), Hubble’s WFC3 (second), and Webb’s #NIRCam (third).

🛎️ It's poll time! In the early history of our Solar System, a Mars-sized object struck the Earth, blasting vapourised rock into space. Recently, the NASA/ESA/CSA James Webb Space Telescope examined the aftermaths of similar upheavals (‘extreme debris discs’) around other stars.
But what was that Mars-sized object that struck Earth called?

#Webb and #Hubble and the little lion 🦁🤏
Arp 107, an interaction between an elliptical galaxy and a larger spiral galaxy, is located 465 million light-years from Earth in the constellation Leo Minor. The view in the first image is a composite, combining data from the #MIRI and #NIRCam on the NASA/ESA/CSA James Webb Space Telescope. The near-infrared data, shown in white, show older stars, which shine brightly in both galaxies, as well as the tenuous gas bridge that runs between them, while the mid-infrared data show the young stars and star-forming regions in vibrant orange and red.
The second image features the NASA/ESA Hubble Space Telescope’s view of the spiral galaxy NGC 3021, which is 100 million light-years away, also in Leo Minor. This galaxy contains Cepheid variable stars and a Type Ia supernova, both of which are useful for making astronomical measurements! 📏

This eerie star-forming scene features the Cat’s Head Nebula! It is seen from the perspective of the NASA/ESA Hubble Space Telescope (first), the NASA/ESA/CSA James Webb Space Telescope’s #MIRI (second), and its #NIRCam (third).
Hubble’s visible-light view shows the cat as a shadowy pillar of dust, while Webb’s infrared-light imagery reveals many stars ✨ and other hidden details.

🆕 Just in time for Halloween, a ghostly nebula lurks within sight of the NASA/ESA Hubble Space Telescope and NASA/ESA/CSA James Webb Space Telescope!
🔴 This is the Cat’s Head Nebula 🐱 a star-forming region located approximately 7,500 light-years from Earth. It is named for its resemblance to a cat sitting with its back towards Earth, its ‘head’ turned to the side.
🔴 Hubble’s visible-light view shows the cat as a dark, elongated pillar of dust, with a glowing red eye 👁️ that may be a young star still partially embedded in the dust.
🔴 Webb’s near-infrared view, from its #NIRCam instrument, reveals a dense scattering of stars that appear blue and yellow. Even in infrared light, some stars are still enshrouded in dust to various degrees!
🔴 In its mid-infrared view from #MIRI however, emission from warm dust and carbon-based molecules outlines intricate structures within the nebula. The blues and greens highlight emission that includes PAHs, carbon-based molecules excited by starlight.

161,000 light-years away, in one of the satellite galaxies orbiting the Milky Way, is the star-forming region N159. This region stretches across 420 light-years, of which about 230 light-years are captured in this image.
N159 is filled with ionised hydrogen gas ☁️ which is being lit up and sculpted by hot young stars. The brilliant emission and sculptural shapes of its clouds of hydrogen gas are captured in this image from the #NIRCam mounted on the NASA/ESA/CSA James Webb Space Telescope.

🛎️ It's poll time! This glittering image features the nearby star-forming region IC 348, which is located just 1000 light-years from Earth.
In which constellation is it found?

Star death and new beginnings in Cassiopeia!
Image 1: This is the famous supernova remnant Cassiopeia A (Cas A) 💥 captured by the #MIRI on board the NASA/ESA/CSA James Webb Space Telescope. On the remnant’s exterior are curtains of material (appearing orange and red), that are due to emission from warm dust. Interior to this outer shell, meanwhile, are filaments of bright pink studded with clumps and knots. This is material from the star itself, likely shining due to a mix of heavy elements and dust emission.
Image 2: This NASA/ESA Hubble Space Telescope image features a class of star-forming nursery ⭐👶 Free-floating Evaporating Gaseous Globules, or frEGGs for short. When a massive new star starts shining from within the cool molecular cloud from which it formed, its radiation can blow a bubble of ionised gas around it. Within this bubble are the frEGGs: compact globules of dust and gas, some of which are also giving birth to low-mass stars!

These stars are stirring up a cosmic cauldron 🧙♀️ in the Large Magellanic Cloud (LMC)!
The star-forming region N159 is found in the LMC. Ultraviolet radiation from its hot young stars is sculpting and lighting up the surrounding gas, creating the fantastical cloudscapes captured here by the #NIRCam on board the NASA/ESA/CSA James Webb Space Telescope.

🆕 Our ESA/Webb Picture of the Month sees stars brewing in a cosmic cauldron ⭐🔮
🔴 This is the star-forming region LHA 120-N 159 (N159), which is located in the Large Magellanic Cloud (LMC). It is what astronomers call a H II region: an area of space filled with ionised hydrogen gas.
🔴 Here, hot young stars are carving into the gas around them with fierce ultraviolet winds 🌬️ the resulting ridges and cavities are captured in marvellous detail in this image from the #NIRCam on the NASA/ESA/CSA James Webb Space Telescope.
🔴 At less than three million years old, N159 is one of the youngest star-forming regions of the LMC 👶✨ containing thousands of stars at their earliest stages of formation!
