Not much is known about exoplanets that are smaller than Jupiter, because of how far they are and their relatively small sizes. However, a study published Friday describes the presence of water and a ...

A 'primitive atmosphere' has been discovered surrounding a distant exoplanet by Nasa scientists. The exoplanet, which sits 430 million light years from Earth, has an atmosphere composed almost ...

A new study led by NASA with contributions from the University of Maryland reveals that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium. Located ...

A study combining observations from NASA’s Hubble and Spitzer space telescopes reveals that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium.

Scientists say HAT-P-26b's atmosphere is relatively clear of clouds and has a strong water signature. Photo: Bloomberg Washington: Scientists using Nasa telescopes have detected “a strong water ...

May 11 (UPI) --Astronomers have discovered a primitive atmosphere surrounding a "Warm Neptune" exoplanet, a Neptune-like world orbiting closer to its host star. The discovery, detailed in the journal ...

A pioneering new study uncovering the 'primitive atmosphere' surrounding a distant world could provide a pivotal breakthrough in the search to how planets form and develop in far-flung galaxies. A ...

THE atmosphere on primitive Earth was much richer in hydrogen than previously thought and could have been the source of the molecules that led to early life, a new analysis shows. The study lends ...
