Radio telescopes help scientists map molecules in space and uncover where and how stars form
You may have heard the phrase "we are made of star-stuff." This statement by the astronomer Carl Sagan refers to the fact that elements heavier than hydrogen and helium were forged in the centers of the first stars. But how ...

What a dry meteorite tells us about water on Mars
Detecting water where none remains today: Neutron and X-ray tomography make it possible. In an international study conducted with the participation of the Paul Scherrer Institute PSI, researchers have brought to light macroscopic ...

The ESCAPE mission will study the evolution of exoplanet atmospheres
The habitable zone concept is useful for understanding which worlds might, possibly, maybe, be habitable. It highlights exoplanets at the right distances from their stars for liquid water to potentially exist on their surfaces. ...

Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
Venus's polygonal plains could point to a watery past
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Zodiacal dust in exoplanetary systems could hinder our search for life on other worlds
If you've ever been under a dark sky in the early morning before dawn, you may have seen a faint glow, almost like a column of light rising from the east. It's sometimes known as the false dawn because it appears before true ...

Laying odds on the potential for Martian water near future landing zones
We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary ...

ELT's spectrograph could 'sniff out' biosignatures on other worlds
Before any major telescope commissioning, there are dozens of papers that attempt to define what we can expect from it. We're starting to see some come through for the Extremely Large Telescope (ELT), which hopefully will ...

Scientists advance space agriculture for future moon and Mars missions
Space isn't known for rich soil or ideal agricultural conditions anywhere in the solar system. Yet amid extreme temperatures and vast distances, multidisciplinary teams at USF's Aerospace: Science, Technology, Research and ...

Could quantum physics help us find Earth 2.0?
When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually ...

How NASA plans to build the Habitable Worlds Observatory
We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should ...

Why Europa's hidden ocean may be more difficult to reach than scientists thought
Europa, one of Jupiter's icy moons, has long fascinated scientists because of what may lie beneath its frozen shell: a global ocean of liquid water. That hidden ocean has made Europa one of the most compelling places in the ...

Finding Venus zone planets with PLATO will show us how habitable planets evolve
Dreams of finding a sort of Earth 2.0 motivate much of the thinking around the search for exoplanets. But there is more to exoplanet science than searching for potentially habitable worlds. Scientists need a deeper understanding ...

Researchers advance tech that could help scientists detect habitable worlds beyond our solar system
Are we alone in the universe? For scientists working on NASA's proposed Habitable Worlds Observatory, that question is no longer purely philosophical. It is increasingly becoming an engineering problem.
