Hubble nets menagerie of young stellar objects

A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula.

Phages and bacteria accumulate distinctive mutations aboard the International Space Station

In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth. Phil Huss of the University of Wisconsin-Madison and colleagues present the findings in the open-access journal PLOS Biology. […]

Massive impact could be the cause of our lopsided moon

Our nearest neighbor, the moon, is still something of a mystery to us. For decades, scientists have wondered why it appears so lopsided, with dark volcanic plains on the near side (the side we see) and rugged, cratered mountains and a thicker crust on the far side. Now we might be closer to knowing why. […]

A quarter-century in orbit: Science shaping life on Earth and beyond

For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration. From growing food and sequencing DNA to studying disease and simulating Mars missions, every experiment aboard the orbiting laboratory expands our understanding of how humans […]

Solar physicists discover long-hidden source of gamma rays unleashed by flares

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth’s nearest star produces its most violent eruptions.

Plasma rings around M dwarf stars offer new clues to planetary habitability

How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie’s Luke Bouma is exploring a new way to probe this critical question—using naturally occurring space weather stations that orbit at least 10% of M dwarf stars during their early lives. He is presenting […]

Lunar spacecraft exhaust could obscure clues to origins of life

Over half of the exhaust methane from lunar spacecraft could end up contaminating areas of the moon that might otherwise yield clues about the origins of Earthly life, according to a recent study. The pollution could unfold rapidly regardless of a spacecraft’s touchdown site; even for a landing at the South Pole, methane molecules may […]

Vera C. Rubin Observatory spots record-breaking asteroid in pre-survey observations

Astronomers analyzing data from Vera C. Rubin Observatory have discovered the fastest-ever spinning asteroid with a diameter over half a kilometer—a feat uniquely enabled by Rubin. The study provides crucial information about asteroid composition and evolution, and demonstrates how Rubin is pushing the boundaries of what we can discover within our own solar system.

Sandblasting on Mars: Camera reveals how prevailing winds shape elongated landforms in volcanic zone

Martian winds can have quite an impact. ESA’s Mars Express has spotted them whipping up sand grains and acting as a cosmic sandblaster, carving out intriguing grooves near Mars’s equator.

Stars that die off the beaten path

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, opening a new window into how exploding stars shape the cosmos. Focusing on M33, a spiral galaxy about 2.7 million light‑years away, this research combined new maps of cold atomic hydrogen gas from the U.S. National […]

Four baby planets show how super-Earths and sub-Neptunes form

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That’s been a source of frustration for planetary scientists, who can’t study them in as much detail as they’d like, leaving one big question: […]

A red moon, a blue moon, a supermoon and more: Your guide to the southern sky in 2026

What will we see in the southern sky in 2026? A total eclipse of the moon (at a convenient time), a blue moon and a supermoon, the two brightest planets close together, and Jupiter disappearing behind the moon in the daytime.

New census of sun’s neighbors reveals best potential real estate for life

A new study led by a Georgia State University astronomy graduate student is a major step forward in the search for stars that could host Earth-like planets that may prove to be good havens for life to develop. Sebastián Carrazco-Gaxiola shared the results at the January 2026 meeting of the American Astronomical Society in Phoenix, […]
