Watching the watchers with Nancy Grace Roman

Astronomers are getting better at gathering data about exoplanets. We have discovered thousands of them, measuring their mass, size, and orbital parameters, and we are starting to measure other aspects such as their temperature ...

Bizarre exoplanet breaks all the orbital rules

In our solar system, the planetary orbits all have a similar orientation. Their orbital planes vary by a few degrees, but roughly the planets all orbit in the same direction. This invariable plane as it's known also has an ...

Mercury's black disk helps sharpen Solar Orbiter's view

This year started with a nice imaging opportunity for Solar Orbiter, and a chance to further improve the quality of its data. On January 3, 2023, inner planet Mercury crossed the spacecraft's field of view, resulting in a ...

Astronomers detect a second planet orbiting two stars

Planets orbiting binary stars are in a tough situation: They have to contend with the gravitational pull of two separate stars. Planetary formation around a single star like our sun is relatively straightforward compared ...

Discovering exoplanets using artificial intelligence

By implementing artificial intelligence techniques similar to those used in autonomous cars, a team from the UNIGE and the UniBE, in partnership with the company Disaitek, has discovered a new method for detecting exoplanets.

TESS discovers new worlds in a river of young stars

Using observations from NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a trio of hot worlds larger than Earth orbiting a much younger version of our Sun called TOI ...
