Innovative sensing technique could improve greenhouse gas analysis

An international team of researchers has used an unconventional imaging technique known as ghost imaging to make spectroscopic measurements of a gas molecule. The new approach by scientists at Tampere University of Technology ...

Unraveling the stellar content of young clusters

About twenty-five percent of young stars in our galaxy form in clustered environments, and stars in a cluster are often close enough to each other to affect the way they accrete gas and grow. Astronomers trying to understand ...

Image: From the Earth, moon and beyond

The purpose of NASA's OSIRIS-REx spacecraft—Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer—is to map and return samples from asteroid Bennu, a carbon-rich hunk of rock that ...

Wireless handheld spectrometer transmits data to smartphone

Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can't be seen by the naked eye. A new smartphone-compatible ...

VTT creates the world's first hyperspectral iPhone camera

VTT Technical Research Centre of Finland has created the world's first hyperspectral mobile device by converting an iPhone camera into a new kind of optical sensor. This will bring the new possibilities of low-cost spectral ...
