The chances of finding extraterrestrial life have improved slightly after NASA announced that its Hubble Space Telescope has confirmed the size of an Earth-sized exoplanet only 22 light-years from Earth.
A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system.
Astronomers have detected silica in exoplanet atmospheres before. But this is the first time they’ve found particles of what appears to be pure quartz.
Researchers were caught by surprise when they observed what they believe to be the aftermath of two giant planets colliding.
in the Trapezium cluster, scientists have found dozens of planet-like objects roughly the mass of Jupiter untethered to any star, drifting through the galaxy in gravitationally-bound pairs.
A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide.
A newly discovered exoplanet has characteristics so peculiar that astronomers think it must have experienced a giant collision some time in its past.
TOI-4860b happens to orbit a tiny star, completing each lap in just 1.52 days. It joins a small number of worlds that pose a fascinating puzzle - there are currently no known formation pathways for such chonkin' planets around such small stars.
By using the Very Large Telescope and the Atacama Large Millimeter/submillimeter Array, astronomers have identified clumps in the thick material around a star named V960 Mon that could gravitationally collapse to form the seeds of planets like Jupiter.
Exoplanet WASP-193b, is nearly 50 % bigger than Jupiter but it's so light and fluffy that its overall density is comparable to that of cotton candy. It's just a hair over 1% of the density of Earth.
The system in which the discovery was made is already famous: PDS-70. It was here that we saw, for the first time, direct images of not just one but two exoplanets in the process of forming, baby gas giants named PDS-70b and PDS-70c
A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System.
A gas giant exoplanet 634 light-years away has a quirk in its atmosphere that suggests it may have swallowed a smaller world.
An object orbiting a star 1,400 light-years away is seriously confronting our notions of what's possible in the Universe.
The belt was discovered around a brown dwarf known as LSR J1835+3259 and is 10 million times more intense than Jupiter's.
