Hubble Learns Galactic History From Stars

A star cluster seen up close, filling the view with thousands of stars. They are clearly divided between blue ones, which are scattered around the outskirts of the image but more towards the center and are the majority in the bright core of the cluster, and yellow stars, which are present in the core but make up most of the cluster outside of that. A few orange stars are closer to us and appear noticeably larger.
This NASA/ESA Hubble Space Telescope image features the globular star cluster called Messier 30 (M30), also called NGC 7099.

This NASA/ESA Hubble Space Telescope image provides a lesson in galactic history. The sparkling collection of stars is named Messier 30 (M30) after the French astronomer, Charles Messier, who cataloged M30 and other diffuse objects that might be mistaken for comets in the early telescopes of Messier’s time. M30 lies about 27,500 light-years away in the constellation Capricornus.

M30 is a globular cluster: a roughly spherical grouping of stars containing anywhere from tens of thousands to millions of stars. These clusters generally reside on the outskirts of galaxies, orbiting within a vast, diffuse region called the halo like a swarm of moths around a lightbulb. Our Milky Way galaxy has at least 150 globular clusters, the nearest of which is about 6,000 light-years away. These clusters are impressively ancient: astronomers estimate their ages are between 11.5 to 13.5 billion years, making certain globular clusters nearly as old as the universe itself.

Globular clusters have long played an important role in helping us learn about our galaxy. More than a century ago, astronomer Harlow Shapley used observations of a particular type of variable star to measure the locations of and distances to dozens of globular clusters within our galaxy. His work showed that the Sun is not in the center of our galaxy, and that the galactic center lies toward the constellation Sagittarius. (His distance measurements were incorrect, however, and he concluded that our galaxy is about twice as large as it really is.)

Today, astronomers continue to learn about our galaxy by observing globular clusters. Because globular clusters are so ancient, they can give us clues about how our galaxy developed long ago. Globular clusters that formed within our galaxy can act as time capsules, preserving the original chemistry of our young galaxy.

However, it’s possible that not all globular clusters that orbit within our galaxy today formed there. Researchers have discovered that M30 and many other globular clusters orbit in the direction opposite from the way our galaxy spins. This may mean that these clusters did not form within our galaxy at all. Instead, our Milky Way galaxy may have captured them in the distant past!

Hubble has observed M30 multiple times. A previously released image of M30 featured data from Hubble’s Advanced Camera for Surveys (ACS) and was part of an observing program (#10775; PI: Sarajedini) that surveyed dozens of Milky Way globular clusters in red and near-infrared light, revealing stars down to just 20% of the mass of the Sun. A more recent program (#13297; PI: Piotto) returned to M30 and other globular clusters in our galaxy, this time observing the clusters with Hubble’s Wide Field Camera 3 and using three filters that captured bluer light. This program collected data that was critical for studying exotic objects like “blue straggler” stars as well as for investigating the multiple populations of stars that can inhabit a single globular cluster.

More recently, Hubble’s ACS viewed many of these globular clusters again. Those observations were part of a program (#16298, PI: Libralato) that looked at how different populations of stars in globular clusters moved over the 15 years since Hubble first observed them — a feat made possible by Hubble’s longevity and ability to discern fantastically small details in distant objects.

The image above was created with data from all three observing programs and includes the wide range of wavelengths Hubble can see — ultraviolet, visible, and near-infrared light. Each wavelength helps us better understand how these groups of stars formed and evolved.

APOD: 2026 November 5 – Enceladus in Silhouette

2026-11-05 05:05

APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Saturn moon Enceladus in silhouette

Enceladus in Silhouette

Explanation: One of our Solar System’s most tantalizing worlds, Enceladus is backlit by the Sun in this Cassini spacecraft image from November 1, 2009. The dramatic illumination reveals the plumes that continuously spew into space from the south pole of Saturn’s 500 kilometer diameter moon. Discovered by Cassini in 2005, the icy plumes are likely connected to an ocean beneath the ice shell of Enceladus. They supply material directly to Saturn’s outer, tenuous E ring and make the surface of Enceladus as reflective as snow. Across the scene, Saturn’s icy rings scatter sunlight toward Cassini’s cameras. Beyond the rings (lower right), the night side of 80 kilometer diameter moon Pandora is faintly lit by Saturnlight.

Cyprus: Island of Snakes, Cats, and Ophiolites

2026-11-05 05:01

The bright salt flats of Akrotiri Salt Lake stand out in a satellite image of the Akrotiri peninsula. Gray urban areas around Limassol spread across the landscape north of the lake, and the blue waters of the Mediterranean Sea surround the peninsula to the south.
Seasonal rains had started to fill Akrotiri Salt Lake when the OLI (Operational Land Imager) on Landsat 8 captured this image of Cyprus’s Akrotiri Peninsula on October 10, 2026.

The island of Cyprus began to form some 90 million years ago during the Late Cretaceous, with molten rock pouring from the seafloor, solidifying, and building new oceanic crust. Over time, portions of this oceanic rock were wrenched upward by tectonic forces, eventually emerging as a rugged island made of ophiolite, a type of rock with a mottled green appearance said to look like the skin of a snake. Remnants of that ancient island are still visible in the dark rocks of the Troodos Mountains.

During the Miocene, considerably younger layers of chalk, limestone, marl, and other marine sedimentary rocks accumulated around the island, providing material that developed into a second, smaller island to the south during a later period of geologic uplift. Over time, sediment poured from rivers into the channel separating the two islands and combined with marine sediments to create deltas and eventually two land bridges, or tombolos. The joined landmass comprises the Akrotiri Peninsula, now the southernmost tip of Cyprus.

The sandy edges of the peninsula were visible when Landsat 8 captured these images on October 10, 2026. Akrotiri Salt Lake, a coastal lagoon that was once an arm of the Mediterranean Sea, lies between the two tombolos. The more westerly feature, the Kouris River tombolo, formed first, developing about 50,000 years ago from river-deposited gravels and sands. The eastern tombolo extended southward from Cyprus, cutting off the Mediterranean Sea only within the past 2,000 years, according to geologists.

The lake’s water levels now vary markedly with the seasons, typically filling in the late autumn and winter and drying out in the summer. The influx of winter water has historically attracted sizable overwintering flamingo populations, averaging about 4,000 birds. However, the wintering flamingo population has declined in recent years, plummeting to 30 birds in 2025, according to news reports. Flamingos have long flocked to the lake to feed on fairy shrimp, which are rich in colorful substances called carotenoids that give the birds their famously pink hue.

Snakes are another of the island’s more notorious animal inhabitants. In antiquity, Cyprus was known as Ophiousa, or “land of snakes,” likely due to its robust population of blunt-nosed vipers. According to legend, the island’s snake communities grew to be so problematic during a drought in the fourth century that the Roman Empress Helena, mother of Constantine the Great, called for shiploads of cats to be sent from Egypt to control the venomous reptiles.

The first feline imports were released in a particularly snake-infested area on the southeastern part of the Akrotiri Peninsula, an area that came to be known as Cape Gata (Cape Cat in Greek). The cape today is still home to the Holy Monastery of St. Nicholas of the Cats, a place where legend says that monks encouraged newly arrived Egyptian cats to hunt snakes. Today, Cyprus has as many cats as people, with more than one million of the feline predators stalking the island. The handful of nuns who now live in the monastery still care for hundreds of cats, according to the St. Nicholas Center. 

The Troodos Mountains’ vegetation and dark underlying rocks make a swath of land in the southwestern part of the island appear darker green than the rest of the island.
