Exoplanets are the celestial bodies orbiting stars other than our Sun. Their small size makes them difficult to detect from Earth, particularly as they appear much dimmer than their parent stars ...

Observations with the James Webb Space Telescope (JWST) have provided new clues about how the exoplanet WASP-121b has formed and where it might have originated in the disc of gas and dust around ...

More than 5,900 of these exoplanets have been identified so far: What was once the exclusive province of science fiction has now become science fact. The title of Keith Cooper’s “Amazing ...

The transforming exoplanet that was observed by the WIYN 3.5-meter telescope at the U.S. National Science Foundation Kitt Peak National Observatory has a strangely elongated orbit. Credit ...

Efforts to spot a new planet come at a time when exoplanet research is booming. Some astronomers studying distant worlds have already observed unusual atmospheres and molecules. In 2020, scientists ...

Possible signs of life on a distant planet? Not so fast. New research shows the signal might just be ordinary molecules, not alien biology. Credit: SciTechDaily.com Scientists recently spotted a ...

NASA's James Webb Space Telescope, they said, had detected signs of a liquid water ocean — and possibly life — on the exoplanet K2-18b, a temperate sub-Neptune world located about 124 light ...

Astronomers observe distant exoplanets like K2-18b by tracking their passage across their host stars, which allows them to analyze how molecules in the planet’s atmosphere absorb specific ...

The new discovery centers on a star called HD 181327, located about 155 light-years away, in the constellation Telescopium. At just 23 million years old, HD 181327 is a cosmic infant compared with ...

So many unexplored secrets still lie at the outskirts of our solar system, where a potential candidate for a new dwarf planet lies. Although space beyond Neptune was thought to be mostly devoid of ...

In April, astronomers said they had detected a possible signature of life on the exoplanet K2-18b. Now, three independent analyses discount the evidence. An artist’s concept of the exoplanet K2 ...

Exoplanets Giant planet discovered around tiny star challenges our best theories Pluto James Webb telescope discovers 'a new kind of climate' on Pluto, unlike anything else in our solar system ...
