Astronomers use Webb to probe a 'steam world' in the constellation Pisces

A Canadian-led international study has revealed new insights into the atmosphere of GJ 9827 d—an exoplanet orbiting the star GJ 9827 in the constellation Pisces, about 98 light-years from Earth—using the James Webb Space ...

Investigating the statistical likelihood of triple star systems hosting exoplanets

Why is it important to search for exoplanets in triple star systems and how many can we find there? This is what a recent study accepted by Astrophysics & Space Science hopes to address after a pair of researchers from the ...

Study suggests moon may have been captured from space rather than formed from collision particles

Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on ...

Study shows Mars' early thick atmosphere could be locked up in the planet's clay surface

Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have been a thick atmosphere ...

Exoplanets could be hiding their atmospheres

Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red ...

Life might thrive on the surface of Earth for an extra billion years

The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to ...

Formation of super-Earths proven limited near metal-poor stars

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars.

Uncovering the role of oxygen concentration in the formation of early Earth magma ocean

It is widely accepted that the early Earth largely consisted of molten magma, forming a global ocean of magma. This extreme state of Earth was likely caused by the intense heat generated from accretionary impacts, meaning ...

Comparing two proposed NASA missions to Jupiter's moon Io

Thanks to NASA's Juno mission to the Jupiter system, we're getting our best looks ever at the gas giant's volcanic moon Io. Even as Juno provides our best views of the moon, it also deepens our existing questions. Only a ...

Earth-like exoplanets might be in short supply for the Habitable Worlds Observatory

How common are Earth-like exoplanets—also called exo-Earths—and which exoplanetary systems should we target to find them?
