Using the Wide Field Camera 3 (WFC3) instrument onboard the NASA/ESA Hubble Space Telescope, astronomers have detected water vapor in the transmission...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have spotted an Earth-sized planet transiting the young Sun-like star HD 63433.
HD...
Astronomers using the NASA/ESA Hubble Space Telescope have detected massive cyclones and other dynamic weather activity swirling on WASP-121b, an ultrahot-Jupiter...
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
There are more than 200 moons in our Solar System, but their relatively small sizes make similarly sized extrasolar moons (exomoons) very hard to detect...
Astronomers from NASA and the University of Washington have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets...
Current theories predict that low-mass stars should rarely host planets with masses exceeding that of Neptune (17 Earth masses).
An artist’s impression...
The bright nearby star HD 110067 hosts six transiting sub-Neptunes that follow a chain of resonant orbits, according to new research led by University...
Astronomers have long puzzled over why all of the planets in our Solar System have slightly slanted orbits around the Sun. But Yale University planetary...
The NASA/ESA/CSA James Webb Space Telescope has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets....
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have captured a high-resolution image of HL Tauri, a young star in the constellation...
LTT 1445Ac, a terrestrial planet in the triple star system LTT 1445, is only 1.07 times the size of Earth, according to a paper to be published in the...
In a paper published in the Proceedings of the Royal Society A: Mathematical Physical and Engineering Sciences, researchers at the University of Cambridge...
A new analysis of data from NASA’s retired Kepler space telescope has revealed a system of seven giant planets around Kepler-385.
An artist’s concept...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
Two new papers in the Astronomical Journal show that in some multiplanet systems, giant planets tend to kick their smaller neighbors out of orbit and wreak...
Astronomers from Trinity College Dublin, the Breakthrough Listen project and Onsala Space Observatory have demonstrated the effectiveness of using multisite...
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a ‘drift...
Young moving stellar groups are the best targets for direct imaging of exoplanets and four massive Jupiter-like planets have been already discovered in...
