Astronomers have unlocked a new way to explore alien worlds by mapping the 3D structure of an exoplanet’s atmosphere for the ...

Scientists have long overlooked white dwarfs as hosts for habitable exoplanets, assuming their lack of fusion would make life impossible. But new climate models challenge that idea, showing that ...

The threat from space rock 2024 YR4 has surpassed that of Apophis, an asteroid feared by scientists 20 years ago. The danger remains low, but experts are estimating the damage that could be done.

Astronomers have achieved a breakthrough in planetary science, revealing the complex weather of a distant gas giant with ...

More pocked with craters than any other object in our solar system, Jupiter's outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA's ...

Last year, astronomers discovered an unusual Earth-size exoplanet they believe has a hemisphere of molten lava, with its ...

Their discovery showed that even tucked away in our innards – in the walls of our stomachs, subjected to vinegar-like pH ...

Astronomers have peered through the atmosphere of a planet beyond the Solar System, mapping its 3D structure for the first time. By combining all four telescope units of the European Southern ...

An international team of astronomers have been able to probe the atmosphere of an exoplanet like never before. Exoplanet ...

Purple Earth Hypothesis suggests Earth was once a purple planet. Early microbes used retinal, not chlorophyll, for ...

Throughout February, these six planets may be seen across the sky at night, as they were in January. But, later in the month, you have the chance to see the planets joined by Mercury, creating an ...

A massive 500,000-mile-wide (800,000-kilometer) coronal hole in the sun's atmosphere is unleashing a stream of fast-moving solar wind toward Earth, potentially supercharging auroras on Jan. 31 and ...
