On the left, an optical image from the Digitized Sky Survey shows Cygnus X-1, outlined in a red box.  Cygnus X-1 is located near large active regions of star formation in the Milky Way, as seen in this image that spans some 700 light years across. An artist's illustration on the right depicts what astronomers think is happening within the Cygnus X-1 system.  Cygnus X-1 is a so-called stellar-mass black hole, a class of black holes that comes from the collapse of a massive star.  New studies with data from Chandra and several other telescopes have determined the black hole's spin, mass, and distance with unprecedented accuracy.

Black holes and other star remnants

Imagine a dog owner with a reflective vest and a black dog without one. In the dark we can see how the dog owner moves, but not the dog. That’s how black holes work, too.

Finding life — and farming minerals — deep under the sea

Japanese researchers have access to the largest scientific vessel ever constructed, one that has a 120 metre tall derrick capable of drilling to 7500 metres below the seafloor. They’re using it to hunt for life deep under the seafloor and explore for mineral deposits at the bottom of the ocean — topics that are of great interest to Norwegian researchers.

Cooled patients are treated differently

What is the best form of first aid for a cold, injured body? Mountain medicine researchers are now co-operating to find the answer. At present there is actually no “best practice” for treating this type of patients.

Inside the ice caves on Svalbard

Svalbard’s cold climate means that its glaciers are solid and frozen to the ground. This allows for winter travel into unique ice caves that contain plants and material that froze into the glacial ice as it formed.

Making Arctic travel safer

Help is not just a phone call away if you have an accident in the Arctic. That’s why the far northern Norwegian archipelago of Svalbard is establishing an educational and research centre for Arctic safety.

A force more deadly than polar bears

You might think that polar bears— and the potential for attack— are the biggest danger on the Norwegian island archipelago of Svalbard. But avalanches kill far more people on Svalbard than polar bears ever have.

One-night stand regrets

Women regret saying yes to casual sex much more often than men do. Men – almost exclusively – regret saying no. Why?

The magical reindeer nose

Every schoolchild knows about Rudolph the Reindeer and his magic red nose. But Rudolph’s real-life counterparts really do have a magic nose. The colder it is, the better it is in keeping the animals warm and hydrated.

Researching the dark side of microplastics

Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.

Charting riches in the ocean depths

The deep sea contains mineral riches that offers a new frontier for research and exploration — and a new way to employ Norway’s deep sea expertise.

NTNU builds bridges to Japan

Starting today, Hiroshito Matsumoto will work from a base in Toyko on behalf of NTNU and the University of Bergen to build new research partnerships between Japan and Norway.

Kon-Tiki2 expedition in Heyerdahl’s wake

The Kon-Tiki2 expedition aims to both reinforce and challenge Heyerdahl’s theories – and NTNU will gather unique research material from the major oceans that the expedition crosses

Timing is everything for renewable energy use

There’s no time to waste in shifting to renewable energy sources if we are to avoid dangerous climate change. That’s especially true when it comes to bioenergy, which causes a temporary increase in CO2 levels that is later removed as replacement biostocks grow.
