Stellar flares may expand habitable zones around small stars
The search for life beyond Earth has traditionally focused on exoplanets orbiting sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target for astrobiology, primarily due to their much longer lifetimes. This also means the habitable zone (HZ), which is the distance from a star where liquid water could exist, is much smaller than our solar system's HZ, and is referred to as the liquid water habitable zone (LW-HZ). In contrast, another type of HZ that involves a star's ultraviolet (UV) radiation potentially enabling life-harboring conditions is known as UV-HZ.
Astronomers find an exo-Jupiter, and it seems to have clouds
A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant Jupiter-like exoplanet called Epsilon Indi Ab.
Are aliens real? Scientists have been hunting for extraterrestrial life since the time of Aristotle
Do aliens exist? Could Earth really be the only planet hosting intelligent life?
Ocean Wave Mechanics Across the Solar System and Beyond
Los Angeles CA (SPX) Apr 16, 2026 -
On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn's largest moon Titan, a similar mild wind would kick up 10-foot-tall waves. That otherworldly behavior
Alien life may hide in plain sight: Statistical patterns across exoplanets move beyond traditional biosignatures
A research team has developed a new approach to detecting life beyond Earth that does not rely on identifying specific biological markers. Instead, the study suggests that life may be detectable through patterns emerging across groups of planets, offering a new framework for astrobiology in situations where traditional biosignatures are ambiguous or unreliable.
Astronomers crack a decades-old mystery, catching gas morphing into planet-building disks around newborn stars
An international team led by Dr. Indrani Das of Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) has shown, for the first time, how infalling gas from star-forming cores gradually transitions into planet-forming disks. Their findings, combining numerical simulations with Atacama Large Millimeter/submillimeter Array (ALMA) observations, are published today in The Astrophysical Journal.
Astronomers reveal always-changing multi-planet system
Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-Earth (TOI-201 d), a warm Jupiter (TOI-201 b), and a brown dwarf (TOI-201 c).
Planets need more water to support life than scientists previously thought
Unfortunately for science fiction fans, desert worlds outside our solar system are unlikely to host life, according to new research from the University of Washington. Scientists show that an Earth-sized planet needs at least 20 to 50% of the water in Earth's oceans to maintain a critical natural cycle that keeps water on the surface.
The Caves That Could Help Us Find, or Become, Aliens
From lava tubes on Mars to ice pockets on Europa, subterranean environments may offer the best chance of finding life—and living safely—beyond our planet.
Europa’s hidden ocean: the NASA mission trying to discover life beneath Jupiter’s ice
NASA’s space mission is traveling to Jupiter to explore the hidden ocean of the moon Europa and discover whether this icy world could harbor life.
