Utterly mind-blowing: This is what 100 Million Stars look like! Take a journey through the most detailed view of the Andromeda Galaxy ever captured as we zoom out from its core. (Credit: NASA, ESA, J. Dalcanton, B. F. Williams, L. C. Johnson, the PHAT team, R. Gendler / Video by Universal-Sci)

A collision on a cosmic scale. The Bullet Cluster consists of two galaxy clusters passing through one another, revealing important clues about dark matter (Video by Universal-Sci - Credit: CTIO/NOIRLab/DOE/NSF/AURA - T.A. Rector & M. Zamani - Music: La Repeticion/Pond5)

What happens after a star explodes? In the Vela supernova remnant, shock waves sculpt surrounding gas into intricate threads. Heated by the explosion’s energy, those threads shine. (Video by Universal-Sci - Credit: ESO/VPHAS+ team. Acknowledgement: Cambridge Astronomical Survey Unit)

Once a spiral galaxy, NGC 524 has lost its gas and settled into a lenticular form about 90 million light-years distant, with a disc dominated by aging red stars and scarce dust. (Credit: ESA/Hubble & NASA - Acknowledgement: Judy Schmidt)

Barnard 86: A dramatic contrast in the Milky Way! The sparkling star cluster NGC 6520 sits beside the strangely shaped dark cloud Barnard 86, surrounded by one of the richest star fields in our galaxy. (Video by WorldAndScience - Credit: ESO - Music credit: La Repeticion/Pond5)

Fascinating: Webb’s view of the Lion Nebula reveals a turbulent landscape of glowing gas and dust, sculpted by a dying star at its heart. Credit: NASA, ESA, CSA, STScI. Image Processing: A. Pagan (STScI)

Can you spot the wings? Sharpless 2-296 gives the Seagull Nebula its birdlike shape, with glowing clouds threaded by dark dust lanes. Video by Universal-Sci - Credit: ESO/VPHAS+ team/N.J. Wright (Keele University)

What happens after a star explodes? Cassiopeia A offers a spectacular glimpse Video by WorldAndScience - Credit: NASA, ESA, CSA, STScI, Danny Milisavljevic (Purdue University), Ilse De Looze (UGhent), Tea Temim (Princeton University)

A view of the Cat’s Eye Nebula, an extraordinary planetary nebula found about 4,400 light-years away in Draco. (Credit: ESA/Hubble & NASA, ESA Euclid/Euclid Consortium/NASA/Q1-2025, J.-C. Cuillandre & E. Bertin (CEA Paris-Saclay), Z. Tsvetanov)

A collision written in starlight Billions of years after colliding with another galaxy, Centaurus A still carries the evidence. Credit: NASA, ESA, CSA, STScI. Image Processing: A. Pagan (STScI), J. Depasquale (STScI), M. Garcia Marin (ESA Office at STScI)

This spectacular view takes us deep into the crowded heart of the Milky Way Near Sagittarius A*, astronomers found evidence that dust and water can form and survive despite the intense radiation surrounding our galaxy’s supermassive black hole (Credit: ESA/Webb, NASA & CSA, F. Peißker, J. Lu)

What looks like a treasure chest is actually a stellar nursery The JWST has captured this extraordinary structure in the Carina Nebula. Known as the Treasure Chest, it contains a compact cluster of roughly 70 young stars (Credit: ESA/Webb, NASA & CSA, M. Reiter - Acknowledgement: M. H. Özsaraç)

Some stars know how to make an entrance. In this nebula, known as Gum 80, the blue-white star HD 165319 lights up the surrounding gas in vivid red. But a nearby bow shock suggests this dazzling visitor is just passing through. (Video by Universal-Sci - Credit: ESO/VPHAS+ team)

Messier 54 is more than just a beautiful concentration of stars. It is a visitor from another galaxy. Rather than belonging to the Milky Way, it is part of the Sagittarius Dwarf Galaxy. (Video by Universal-Sci - Credit: ESO - Music credit: La Repeticion/Pond5)

A spectacular view of the Pillars of Creation (Messier 16)! Video by Universal-Sci - Credit: NASA, ESA, CSA, STScI; Image Processing: Joseph DePasquale, Anton Koekemoer, Alyssa Pagan

Before stars shine, they hide. The Trifid Nebula shelters developing stars deep inside clouds of gas and dust. (Video bij Universal-Sci - Credit: NSF–DOE Vera C. Rubin Observatory/NOIRLab/SLAC/AURA)

A stunning look into the heart of our galaxy. This colour-composite infrared image reveals newly identified massive stars and complex structures in the hot ionised gas Video by Universal-Sci - Credit: NASA, ESA and Q.D. Wang (University of Massachusetts, Amherst)

It looks ominous, but this cloud is full of beginnings. Around 620 light-years away, Chamaeleon I is home to hundreds of new stars Video by Universal-Sci - Credit: CTIO/NOIRLab/DOE/NSF/AURA - Image Processing: T.A. Rector (University of Alaska Anchorage/NSF NOIRLab), M. Zamani & D. de Martin

The speed of light is blindingly fast but also surprisingly slow. It is the fastest thing in the universe, yet space is so vast that even light seems to crawl from certain perspectives… (Credit Dr. James O'Donoghue)

Spectacular: Within the Carina Nebula, vast pillars of hydrogen and dust take shape under the relentless influence of radiation and stellar winds (Credit: NASA, ESA, and the Hubble Heritage Project (STScI/AURA); Acknowledgment: M. Livio (STScI) and N. Smith/University of California, Berkeley)

A stellar nursery meets a chandelier of stars. This DECam image brings together the glowing Corona Australis Molecular Cloud and NGC 6723, a dazzling globular cluster far beyond it. (Credit: Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA - T.A. Rector, R. Colombari & M. Zamani)

A cosmic steering wheel, 33 million light-years away. NGC 1269’s central bar and wheel-like disks may preserve traces of an ancient galactic merger, captured here by DECam. Credit: Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA Image processing: R. Colombari & M. Zamani (NSF NOIRLab)

NGC 4303 (also referred to as Messier 61) is a spectacular example of a starburst galaxy. In there new stars are being created at a much faster rate than usual, offering astronomers a glimpse into the dynamics of star creation... (Credit: ESO/PHANGS)

Look to the night sky just before dawn or after dusk at certain times of year, and you may spot a faint column of light rising from the horizon. This eerie glow is called zodiacal light, created when sunlight reflects off countless tiny dust particles in space. (Credit: NASA/JPL-Caltech)

Powerful winds. Exploding stars. New beginnings. This Hubble view of nebula N44 reveals how stars reshape their surroundings, sweeping gas into a glowing shell where more stars are taking shape. (Credit: ESA/Hubble & NASA, D. Gouliermis)
