This is potentially enough to build planetary systems larger than our own solar system,” announced Dr. Katie Hesterly of the SKA Observatory, when she revealed the first direct observation of ...

A key method of forming planets finally has observational evidence, thanks to a network of radio telescopes in the U.K. that ...

This giant planet orbits its star so closely that it completes a full orbit in just 30.5 hours. Its dayside reaches a scorching 3000°C, while the eternal nightside cools down to 1500°C. You would ...

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of ...

TOI-6894 b, the largest exoplanet relative to its host star yet seen, doesn’t fit the most widely accepted formation model ...

A recent astronomical discovery has shaken long-held beliefs about how planets form. For decades, scientists thought that stars much smaller than our Sun couldn't form giant planets.

Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how planets form.

The planet (TOI-6894b) is a low-density gas giant with a radius a little larger than Saturn's but with only ~50% of Saturn's mass.

Jupiter is our solar system's biggest planet by far. It used to be twice as large: Study A recent study found that Jupiter was once twice the size that it is now, making it big enough to swallow ...

The team looked a four gas giants in the star system HR 8799 using the James Webb Space Telescope’s infrared imaging tools and found evidence the planets’ atmospheres are rich in carbon dioxide, ...

The gas giants outside our solar system are not capable of hosting extraterrestrial life, but do offer clues in a lingering mystery about how distant planets form, researchers said.
