This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname “Lost Galaxy.”

Light from the half a million satellites that humanity is planning to launch into Earth’s orbit in the coming years could contaminate almost all the images taken by space telescopes, NASA astronomers warned Wednesday.

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient progenitors of galaxies like ours were small galaxies similar to modern-day dwarf galaxies like the Large and Small Magellanic Clouds. Research shows that both dwarf galaxies and ancient galaxies are less massive, have lower metallicity, […]
Surprisingly, some of the universe’s brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational astrophysicists has developed the most comprehensive simulations ever made of how black holes create these dazzling light shows.

Since the 1950s, humanity has been searching for extraterrestrial life with increasingly sophisticated tools. But after decades of space probes, meteorite analysis, radio telescopes, and UFO investigations, what have we actually found? A new piece of analysis by a team led by Seyed Sina Seyedpour Layalestani from the Islamic Azad University in Iran has looked […]
One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported here by asteroids or other celestial bodies. While these molecules have been found in meteorite samples that have crash-landed […]
A strong geomagnetic storm in spring 2024 brought the northern lights unusually far south, as the auroral oval expanded well beyond its typical position. “I am surprised at how sparse the measurement network is, even though we know that the impacts of space weather can vary greatly from one area to another,” says Doctoral Researcher […]
A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction between dark matter and dark energy significantly influences the rotation and shape alignment of dark matter halos in the universe.

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR solar telescope in Tenerife, researchers recorded the explosive activity of the sun’s most energetic sunspot group of 2025, revealing twisted magnetic structures and the early stages of flare […]
Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide insight into how stars form within giant molecular clouds, making them important indicators of star formation and cluster evolution.
