Astronomers have uncovered a planetary system that challenges conventional theories of planet formation. The system likely includes a rocky planet that formed beyond the orbits of its gaseous ...

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver ...

According to these calculations, Earth's total lifespan will be about 9.5 billion years.

Astronomers have reported one of the longest stellar dimming events ever recorded, with a Sun-like star fading by 97 percent for nearly 200 days. Astronomers believe one of the longest stellar dimming ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers ...

Four planets observed orbiting a red dwarf star; rocky outermost planet challenges formation theory, says scientists.

The system, observed using the European Space Agency's Cheops space telescope, consists of four planets — two rocky and two ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

The James Webb Space Telescope has detected the first-ever spectral signature of hydrogen sulfide around a massive gas giant planet.

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

As next-generation telescopes map this outer frontier, astronomers are bracing for discoveries that could reveal hidden planets, strange structures, and clues to the solar system’s chaotic youth.
