Extreme power of black hole revealed

Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in the hot gas surrounding it and prevented trillions of stars from forming.

Get used to heat waves: Extreme El Nino events to double

Extreme weather events fuelled by unusually strong El Ninos, such as the 1983 heatwave that led to the Ash Wednesday bushfires in Australia, are likely to double in number as our planet warms.

Ultraviolet light to the extreme

When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet.

Global warming blamed for extreme summer heat

A recent statistical analysis conducted by NASA concludes that Earth's land areas have become much more likely to experience an extreme summer heat wave than they were in the middle of the 20th century.

Prepare for more extreme weather, say scientists

Climate change is set to trigger more extreme weather events around the world, an international team of scientists claims.

Extreme weather linked to global warming

Climate scientists have in the past been cautious about suggesting that extreme weather can be linked to climate change. But a new report from the Potsdam Institute for Climate Impact Research (PIK) argues just that.
