Hubble watches star clusters on a collision course

(Phys.org) -- Astronomers using data from NASA's Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic ...

Too soon to say if climate is changing cloud heights

A new analysis of 15 years of NASA satellite cloud measurements finds that clouds worldwide show no definitive trend during this period toward decreasing or increasing in height. The new study updates an earlier analysis ...

Star formation may be halted by cold ionized hydrogen

For the first time ionized hydrogen has been detected at the lowest frequency ever towards the center of our Galaxy. The findings originate from a cloud that is both very cold (around -230 degrees Celsius) and also ionized, ...

NASA sees twin typhoons headed for double China landfall

NASA's Terra satellite captured two tropical cyclones on visible imagery today, August 1 as they head for landfall. Typhoon Saola is approaching Taiwan and Typhoon Damrey approaching southern Japan, are both headed for landfall ...

Pollution yields longer-lasting storm clouds

(Phys.org) —A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. Appearing in the Proceedings of the National Academy of Sciences November 26, the results solve a ...

Using artificial intelligence to better predict severe weather

When forecasting weather, meteorologists use a number of models and data sources to track shapes and movements of clouds that could indicate severe storms. However, with increasingly expanding weather data sets and looming ...
