Astronomers using the Hubble Space Telescope have detected water molecules in the atmosphere of a small, blazing-hot exoplanet 97 light-years from Earth. The planet, named GJ 9827d, is about twice ...

Where is it? Otago region, New Zealand [-45.39649095, 170.20379599] What's in the photo? An elongated lenticular cloud known as the "Taieri Pet" Which satellite took the photo? Landsat 8 When was ...

The conditions in the water vapor cloud around HL Tauri are thought to resemble those during Earth's formation 4.5 billion years ago, providing insights into how habitable planets might develop.

Water also exists mostly as ice in the dense clouds that form stars,” said Watson. “Now we’ve seen that water, falling as ice from a young star system’s envelope to its disk, actually ...

Scientists had assumed that the ice in space was purely amorphous, but new experiments show it can have a partly crystalline structure similar to ice on Earth.

At Rothera, the mesopause temperature was minus 120 degrees Celsius, which is too warm for polar mesospheric clouds to form under typical water vapor concentrations.

A recent satellite image captured the reemergence of a unique, UFO-like cloud, known as the "Taieri Pet," which appears above New Zealand's South Island when conditions are just right.
