Studying exoplanets has given astronomers insights into the characteristics that could help them find life beyond Earth. For years, astronomers thought an exoplanet’s location in a star’s habitable zone was enough to make it an Earth-like world. But some stars are more active than our sun, exposing planets in their habitable zones to far more radiation than Earth receives. Astronomers have increasingly recognized that a planet’s magnetic field, which shields Earth from harmful radiation, could be a key characteristic in identifying Earth-like worlds.

Now, an international team of scientists is shedding light on how to study exoplanet magnetic fields in a chapter published in Advancing Astrophysics with the SKA II, a 2026 science book sponsored by the Square Kilometer Array Observat...

The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy

The Roman Space Telescope has been under development for about a decade under NASA’s leadership and is scheduled to launch on Aug. 30, 2026, at 7:26 a.m. EDT. The telescope is named after Nancy Grace Roman, who was considered the architect of NASA’s modern science program and, among other efforts, dedicated herself to the success of the Hubble Space Telescope project.

Roman’s destination is the L2 Lagrange point, a specific location 1...

-Advancing the search for weird life on weird planets

Scientists have identified a promising new way to detect life on faraway planets, hinging on worlds that look nothing like Earth and gases rarely considered in the search for extraterrestrials.

In a new Astrophysical Journal Letters paper, researchers from the University of California, Riverside, describe these gases, which could be detected in the atmospheres of exoplanets – planets outside our solar system – with the James Webb Space Telescope, or JWST.

Called methyl halides, the gases comprise a methyl group, which bears a carbon and three hydrogen atoms, attached to a halogen atom such as chlo...

The search for exoplanets—planets that orbit stars located beyond the borders of our solar system—is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are physically similar to the gas giant planet Jupiter from our own neighborhood.

Unlike “our” Jupiter, hot Jupiters orbit very close to their stars, complete a full orbit in just a few days or even hours, and—as their name suggests—have extremely high surface temperatures. They hold great fascination for the astrophysics community...
