Milky Way relic uncovered & Fermi finds sibling supernovas - Space News (Jun 20, 2026)

Imagine finding out that a familiar "star cluster" near the heart of our galaxy is not a simple cluster at all, but the fossil core of a long-vanished system that helped build the Milky Way more than 12 billion years ago.[12] Welcome to The Automated Daily, space news edition. The podcast created by generative AI. Today is June 20th, 2026, and I’m TrendTeller, here to walk you through the most interesting space stories from roughly the last twenty-four hours.[7][12] We’ll start with that surprising Milky Way fossil, touch on new high-energy insights from NASA’s Fermi mission, check in on a fresh SpaceX launch from California, and then look up at what you can see in the sky this weekend.[15][2][9] We’ll close with a couple of human stories, from a NASA trailblazer being honored to an asteroid named after a beloved musician.[5][17] Let’s get into it.

Milky Way relic uncovered

First up, that remarkable update from the center of our own galaxy. Astronomers using NASA’s James Webb and Hubble space telescopes have shown that Terzan 5, a dense, crowded group of stars in the Milky Way’s central bulge, is not a normal globular cluster as once thought.[12] For years, Terzan 5 was puzzling because its stars did not all share the same age and chemical makeup, which is what you typically see in classic globular clusters that formed in a single burst early in the universe.[12] By combining Webb’s infrared capabilities with Hubble’s long record of optical observations, researchers have now teased apart the different stellar populations inside Terzan 5 with much greater precision.[12] What they find is a complex history written in starlight. The new analysis confirms not just two, but up to four distinct generations of stars inside Terzan 5, forming roughly 12.5, 4.7, 3.8, and 2.5 billion years ago.[12] That spread in ages and the way the stars’ chemical elements are distributed suggest that Terzan 5 is a self-contained, self-enriching stellar system that managed to hold onto gas and form new stars multiple times, something small globular clusters cannot usually do.[12] The most likely explanation is that we are looking at the surviving core of a much more massive building block that once helped form the Milky Way’s central bulge, before most of its outer stars were stripped away over cosmic time.[12] In other words, this object is a fossil remnant of the chaotic era when our galaxy was assembling its inner regions. This matters because direct evidence of those early building blocks is rare; most of them were torn apart and mixed into the Milky Way long ago.[12] Terzan 5 gives astronomers a unique nearby laboratory to study how stars formed, evolved, and chemically enriched their surroundings in the first billion years after the Big Bang.[12] It also shows the power of combining Hubble’s long baseline of data with Webb’s sharp infrared vision, which can peer through dust toward the galactic center. As more such relics are identified and studied, we should get a much clearer picture of how spiral galaxies like ours grew from smaller pieces into the grand structures we see today.[12]

Fermi finds sibling supernovas

Staying in the realm of distant, energetic events, NASA has also highlighted new work from its Fermi Gamma-ray Space Telescope. In its latest science roundup, NASA points to a discovery of “possible sibling” supernova remnants that share remarkably similar high-energy signatures.[7] Supernova remnants are the expanding shells of gas and dust left behind when massive stars explode, and they glow in gamma rays when shock waves accelerate particles to near light speed.[7] By comparing the gamma-ray emission from different remnants, scientists can look for patterns that hint at common origins, such as stars born in the same region or exploding under similar conditions. In this case, the Fermi data suggest that at least two remnants may be more closely related than most. NASA’s description of them as “possible sibling supernova remnants” reflects the idea that they may have formed from similar types of massive stars, or even from stars that lived and died in the same stellar family, although more work is needed to pin that down.[7] The significance lies in what this can tell us about how massive stars end their lives and how efficiently these explosions pump high-energy particles into the galaxy.[7] Better understanding those processes feeds directly into models of cosmic rays, the chemical evolution of galaxies, and even the environments that later generations of stars and planets are born into. It is a reminder that our own solar system formed in a galaxy constantly reshaped by such powerful, short-lived giants.

SpaceX launches NROL-179

From deep space, let’s come closer to home and talk launches. In the early hours of June 19th local time, SpaceX successfully launched the NROL-179 mission from Space Launch Complex 4 East at Vandenberg Space Force Base in California.[15] Liftoff came at about 1:50 a.m. Pacific time, right on schedule, sending a Falcon 9 rocket carrying a classified payload for the U.S. National Reconnaissance Office into orbit.[15] Shortly after launch, the mission team confirmed successful stage separation, indicating that the rocket performed as planned through the early phases of flight.[15] Because this is a national security mission, details about the exact orbit and the satellite’s purpose are not being shared publicly. Even with that secrecy, the launch is still notable for a couple of reasons. First, it continues a steady cadence of Falcon 9 flights from both U.S. coasts, reflecting how routine orbital launches have become for SpaceX.[10][15] Second, the booster flying this mission had a relatively short turnaround time between flights, underscoring the company’s emphasis on reusability to keep costs down and availability high.[15] For the National Reconnaissance Office, tapping into this commercial launch capability helps ensure reliable, flexible access to space-based assets that support everything from reconnaissance to secure communications. For the broader launch industry, each successful mission like this reinforces the trend toward frequent, reusable flights as the new normal.

Saturn moon dance and planets

Now, if you are the kind of person who likes to simply step outside and look up, there has been plenty to enjoy in the sky over the last day or so. Early on June 19th before dawn, observers along the U.S. West Coast had a chance to watch Saturn’s small moon Dione pass due north of the ringed planet.[2] A couple of hours before sunrise, Dione appeared just northeast of Saturn, gradually drawing closer as the night wore on.[2] By shortly before 4:30 a.m. Pacific time, the moon’s apparent path took it directly north of the planet, creating a delicate pairing in the eyepiece for those equipped with a telescope and clear skies.[2] While other, fainter moons like Enceladus may have been harder to spot, this close approach of Dione was a nice reminder of how dynamic the Saturn system looks even from Earth. If you missed that, there is still plenty happening in the evening sky. Astronomy guides this week highlight a striking scene in the western sky after sunset, where a line of bright objects stretches upward from the horizon.[9] Near the top of that line, the Moon passes near the bright star Regulus in Leo, while brilliant Venus sits in the constellation Cancer, not far from the Beehive Cluster, also known as M44.[9] Slightly lower, you can spot Jupiter, and lower still, closer to the horizon, is Mercury, which is faint but visible if you have a clear, unobstructed view west.[9] When the sky is dark enough, binoculars can reveal the sparkling stars of the Beehive Cluster next to Venus, making for a picturesque combination of planet and star cluster in one field of view.[9] NASA’s own June skywatching guide has been pointing to this broader stretch of planetary activity throughout the month, including the earlier conjunction of Venus and Jupiter and the arrival of the June solstice, which marks the start of astronomical summer in the Northern Hemisphere.[8] As the evenings grow warmer, the familiar Summer Triangle of bright stars Vega, Altair, and Deneb climbs higher, bringing with it deep-sky targets like the Ring Nebula and the Dumbbell Nebula for those with telescopes or cameras.[8] It is a good time of year to reconnect with the night sky, whether you are tracking planetary alignments or simply enjoying the Milky Way rising later at night.

Honoring Annie Easley at NASA

Space news is not just about rockets and distant galaxies; it is also about the people who made it possible. One of the human stories highlighted in the last day is a renewed look at Annie Easley, featured as a NASA-related photo of the day and described as a hero of the agency.[5] Easley was a computer scientist, mathematician, and rocket engineer who worked at NASA and its predecessor agency starting in the mid-twentieth century, contributing to software that supported early rocket and energy technologies.[5] She helped develop and analyze code for the Centaur rocket stage, which eventually became a key part of launching many scientific and commercial missions, even though her name was not widely known outside aerospace circles for many years.[5] Her career unfolded in the context of segregation and limited opportunities for Black women in technical fields, making her achievements all the more significant. This recognition comes right as the United States observes Juneteenth, the June 19th holiday that marks the enforcement of the Emancipation Proclamation in Texas in 1865 and the broader end of slavery in the country.[3][6] Juneteenth was established as a federal holiday in 2021, and many communities use it as a moment to reflect on both progress and remaining gaps in equality, including in science and engineering.[3][6] Linking Annie Easley’s story to this period highlights how crucial diverse voices have been, and continue to be, in space exploration. As NASA and other institutions push toward ambitious goals like lunar missions and Mars exploration, they are building on foundations laid in part by people like Easley, whose work quietly shaped the tools and techniques used today.[5]

Asteroid named for Elliott Smith

We will wrap up with a small but charming item that sits at the crossroads of space and culture. An update making the rounds notes that an asteroid has been officially named after the late singer-songwriter Elliott Smith, known for his introspective, influential music.[17] The post credits Orlando Campopiano, an independent filmmaker based in Edinburgh, with helping to bring about the naming, which follows the established process of submitting naming proposals for numbered minor planets to the International Astronomical Union.[17] Once approved, such names give these otherwise anonymous chunks of rock a bit more personality, connecting the world of planetary science with the broader arts community. This is not unusual in astronomy: many asteroids honor scientists, artists, writers, and other cultural figures, turning the asteroid belt into a kind of celestial hall of fame. In Elliott Smith’s case, it offers fans a poetic image of their favorite musician now being literally written into the sky, orbiting the Sun among countless other named and unnamed bodies.[17] For astronomers, the scientific work on the asteroid—tracking its orbit, measuring its properties—continues as usual. But for the public, this kind of story is a reminder that space is not just a technical frontier; it is also a place where our culture, our history, and our imagination all find new ways to leave a mark.

That’s it for today’s run through the latest in space, from a fossil relic at the heart of the Milky Way to a quiet asteroid now carrying the name of a beloved musician.[12][17] If any of these stories caught your interest, I encourage you to dig a little deeper into the images, data, and history behind them; there is always more to discover than we can fit into a few minutes.[7][5] You’ve been listening to The Automated Daily, space news edition, with TrendTeller. Thanks for spending part of your day staying curious about the universe, and I’ll talk to you next time.
