A young Sun-like star has been caught blowing a giant cosmic bubble.

For the first time, NASA’s Chandra Observatory observed an “astrosphere” forming around a young star. Powerful stellar winds streaming from the star push outward, inflating a vast bubble of hot gas that expands into the colder gas and dust of the surrounding galaxy.

Our own Sun creates a similar protective bubble known as the heliosphere. This enormous region, carved out by the solar wind, stretches far beyond the planets of our Solar System and helps shield Earth from cosmic radiation.

Studying astrospheres around other stars helps scientists understand how the Sun’s heliosphere formed, what shape it might have, and how it has evolved over billions of years as the Sun travels through the Milky Way.

In the image: the star appears in infrared and X-ray light, surrounded by a hazy purple bubble extending above and below it, with dusty wings that resemble a moth.

A Small Galaxy With a Big Stellar Boom

Welcome to the dwarf galaxy UGC 5340 — a compact cosmic system bursting with star formation. While small compared to giants like the Milky Way, dwarf galaxies like this one are among the most active and dynamic environments in the universe.

In the lower right corner of the image, astronomers spotted a particularly intense pocket of star birth. This stellar nursery was likely triggered by a gravitational interaction with a nearby companion galaxy just outside the frame. Such encounters can compress gas clouds, igniting waves of star formation.

The Hawk That Hunts Failed Stars

Spanning the sky like a hawk with outstretched wings, the RCW 36 nebula glows above a cluster of massive newborn stars. Located about 2,300 light-years away in the constellation Vela, this dramatic region is a bustling stellar nursery wrapped in gas and dust.

While the brightest, most massive young stars immediately catch the eye, astronomers turned their focus to something far more elusive: brown dwarfs. These faint, “failed stars” are unable to sustain hydrogen fusion in their cores, making them difficult to detect in visible light. Using the HAWK-I instrument on the Very Large Telescope, researchers observed the region in infrared wavelengths, where these cooler objects shine more clearly. Equipped with adaptive optics to correct for atmospheric turbulence, HAWK-I delivers remarkably sharp images—allowing scientists to probe the hidden population of dim stellar objects within this striking nebula.

A Giant Galaxy Stretched by Gravity

NGC 6872 is no ordinary spiral galaxy. Captured in part by NASA’s Chandra X-ray Observatory, this colossal system lies about 300 million light-years away in the constellation Pavo (the Peacock) and spans an astonishing 522,000 light-years—more than five times the width of our Milky Way.

If massive galaxies, gravitational encounters, and cosmic evolution fascinate you, join the SpaceInfo Club free newsletter for space opportunities and engaging discussions about the frontiers of space.

Dominating the scene, NGC 6872 unfurls two enormous spiral arms that stretch outward and curve back around a bright central core. Its vivid purple hues fade into dusty blue along the outer arms, while stars shimmer throughout the structure. Near the center-left, a much smaller galaxy glows brightly—this companion passed through NGC 6872 over 100 million years ago. That dramatic encounter likely distorted the giant spiral, helping shape its unusual elongated form. Scattered points of distant stars and galaxies dot the black background, framing one of the largest known spiral galaxies in breathtaking detail.

A Cosmic “Brain” and a Star’s Uncertain Fate

At first glance, it looks like a glowing brain in space—complete with what seem to be left and right hemispheres. In reality, this striking structure is a dying star expelling a vast shell of gas, surrounded by a complex cloud of energized material. The dark lane dividing the two lobes may be linked to an outflow streaming from the central star, shaping the nebula’s dramatic symmetry.

If stellar life cycles and the fate of dying suns capture your imagination, join the SpaceInfo Club free newsletter for space opportunities and engaging discussions about the frontiers of space.

What happens next depends entirely on the star’s mass, which astronomers have yet to determine. If it’s a high-mass star, its future could end in a powerful supernova explosion. If it’s more like our Sun, it will continue shedding its outer layers more gently, eventually leaving behind a dense white dwarf—the exposed core of what was once a luminous star. Either path represents a profound transformation, returning material to the cosmos and influencing future generations of stars.

A Galaxy in Constant Ebb and Flow

NGC 5134 sits about 65 million light-years away in the constellation Virgo—practically a neighbor in cosmic terms. The light captured by the NASA/ESA/CSA James Webb Space Telescope to create this image began its journey toward us not long after Tyrannosaurus rex roamed the Earth. What we see today is ancient history arriving in stunning detail.

If tracing the life cycle of galaxies across deep time excites you, join the SpaceInfo Club free newsletter for space opportunities and engaging discussions about the frontiers of space.

By combining data from two of its powerful instruments, Webb paints a richly layered portrait of NGC 5134. MIRI detects the mid-infrared glow from dust scattered throughout the galaxy’s interstellar clouds, while NIRCam captures near-infrared light primarily from stars and star clusters lining its spiral arms. Together, these observations reveal a galaxy in motion—gas clouds collapsing to form new stars, young stars gradually consuming the available fuel, and dying stars returning enriched material back into the galactic environment. It’s a continuous cosmic recycling process, shaping the future of this spiral system.
