Scientists Find Evidence Suggesting Atmosphere On Habitable "Super-Earth"
Astronomers have discovered more than 6,200 exoplanets since the first ones were found in the 1990s.
Giant waves are sweeping Mars’ atmosphere into space
The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge. Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space. The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable planet.
Amendment 68: New Opportunity: D.8 Habitable Worlds Observatory Precursor Science Investigations
The Habitable Worlds Observatory (HWO) is a large-aperture ultraviolet/visible/near-infrared observatory concept recommended by the National Academies of

Finding widens selection of rocky planets that may once have been habitable
'It's absolutely exciting!': Astronomers discover an atmosphere around an Earth-like planet in the habitable zone for first time ever
Astronomers have detected helium escaping from the super-Earth LHS 1140 b, providing the strongest evidence yet that a rocky planet in another star's habitable zone has retained an atmosphere for billions of years.
Astronomers Find an Atmosphere on a Nearby Earthlike Planet
It’s the first potentially habitable world known to host an atmosphere, making it a lead contender in the search for life beyond our solar system.
Earth-like exoplanet could have life-supporting water on its surface
Scientists discover the first confirmed atmosphere in habitable zone outside our solar system on LHS 1140b
First atmosphere detected on a habitable-zone rocky world
In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star.
Scientists identify nearby 'super-Earth' as promising candidate in search for alien life
NASA plans to launch the Habitable Worlds Observatory in the 2040s, a mission whose goal is “to image Earth-like planets around other sun-like stars,” according to NASA’s website.
Student research in Yellowstone could help scientists understand life on other planets
Arizona State University doctoral candidates Tanner Barnes and Vince Debes both enjoy a good hike. But when they set out on trails in places like Yellowstone National Park, they are not just taking in the sights — they are collecting samples that could answer some of science’s biggest questions: how life survives in extreme environments, how planets become habitable and what signs of life scientists should look for beyond Earth.
A Critical UV Legacy: A Hubble Roadmap for HWO Science Readiness
The Habitable Worlds Observatory (HWO) will provide the first opportunity to directly image and spectrally characterize terrestrial exoplanets
Biosphere 2 poised to become a launchpad for landscape terraformation science
"From Early Earth to Mars" explores how life can transform planets in an effort to make Mars habitable while keeping Earth livable. At Biosphere 2, the LEO Survey's massive hillslopes allow researchers to monitor how bare rock gradually evolves into biologically active terrain in real time and virtually via a digital twin model.
There Are 45 Earth-Like Worlds Where Aliens May Exist, Scientists Say
Scientists identify 45 potentially habitable exoplanets, using exact data and quotes to guide future telescopes in the search for extraterrestrial life.
Scientists Discover a Major Flaw in How We Search for Life on Other Planets
Planets can't remain habitable for long without a massive hidden supply of water.
Planets need more water for life than scientists thought
A new study explores how much surface water a planet needs to support life.
What would happen to Earth if the sun suddenly vanished?
Earth is habitable due to warmth from the sun. So what would happen if the sun disappeared?
Optical Vortex Phase Masks for the Detection of Habitable Worlds
A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of starlight suppression needed for future space observatories to pick out very faint habitable exoplanets from the far brighter glare of their stellar hosts.
Israel deliberately targeting medical facilities in south Lebanon, say health workers
Medics and officials say there is systematic use of double-tap strikes in campaign to make the south uninhabitable
Alien Life Could Look Nothing Like What We Expect. Here's How Microbes Beyond Earth Might Live Without Liquid Water
Like the lead character of “Project Hail Mary,” some scientists are proposing ways that life might exist beyond a star’s “habitable zone,” often considered the gold standard of potential livability
Earth’s continental plates were moving 3.48 billion years ago
Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its start back by 140 million years.
The best places to look for alien life: Scientists identify 45 Earth-like worlds to explore for a 'Project Hail Mary'
If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look for it. They have identified just under 50 rocky worlds most likely to be habitable out of the ...
Scientists discover hidden water beneath Mars that could have supported life
New research suggests Mars may have remained habitable much longer than scientists once thought. Ancient sand dunes in Gale Crater appear to have been soaked by underground water billions of years ago, leaving behind minerals that can preserve signs of life. Even after surface water disappeared, subsurface flows may have created protected environments for microbes. These hidden habitats could be key targets in the ongoing search for past life on Mars.
ASU-led SPARCS mission achieves 'first light,' marking the start of its science operations in orbit
The Star-Planet Activity Research CubeSat, or SPARCS, has captured its first images of stars from space. This milestone marks the start of its science operations in orbit.Arizona State University leads the SPARCS mission, which is funded by NASA. It is the first CubeSat mission dedicated to long-term ultraviolet monitoring of nearby low-mass stars. These stars are the most common in our galaxy and often have Earth-sized, possibly habitable planets.
