The water molecule is a key ingredient in the formation of planetary systems. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA)...
Using the Wide Field Camera 3 (WFC3) instrument onboard the NASA/ESA Hubble Space Telescope, astronomers have detected water vapor in the transmission...
Terrestrial and sub-Neptune exoplanets are expected to form in the inner regions of protoplanetary disks around their parent stars. Water plays a key role...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
The new observations from the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope show that the main-belt comet 238P/Read...
Gliese 1214b is a so-called mini-Neptune, a smaller, denser version of Neptune that consists of a rocky core surrounded by a thick blanket of gas.
This...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
Using a new probe that detects tiny amounts of moisture on sand grains, a team of researchers from Cornell University, the Ecole Polytechnique de l’Université...
Atmospheric lakes are long-lived pools of water vapor that occur over the western Indian Ocean and bring water to dry lowlands along East Africa’s coastline.
Long-lived...
Observations by the NASA/ESA Hubble Space Telescope in far-ultraviolet light of Jupiter’s icy moons were used in the past to detect molecular oxygen...
Insulating materials can in principle be made metallic by applying pressure. In the case of pure water, this is estimated to require a pressure of 48 Mbars...
Jupiter’s icy satellite Ganymede is the largest moon in the Solar System. Water ice on its surface is frozen solid in frigid temperatures as low as minus...
In a study published recently in the Astrophysical Journal Letters, a team of astronomers analyzed spectroscopic atmospheric data from 19 exoplanets, ranging...
Astronomers have for the first time managed to detect water vapor above the surface of Jupiter’s icy moon Europa.
Artist’s concept of ocean on Jupiter’s...
