New infrared technique aims to remotely detect dangerous materials
For most people, infrared technology calls to mind soldiers with night-vision goggles or energy audits that identify where heat escapes from homes during the winter season.
Image: Hubble sees a star set to explode
(Phys.org) —Floating at the center of this new Hubble image is a lidless purple eye, staring back at us through space. This ethereal object, known officially as [SBW2007] 1 but sometimes nicknamed SBW1, ...
Detecting diamonds with X-ray technology
X-rays penetrate objects and reveal information about its contents. Using two X-ray spectra, you can identify different materials. And now, a new algorithm is making it possible to find diamonds in the rock.

Hubble revisits the Monkey Head Nebula for 24th birthday snap
(Phys.org) —To celebrate its 24th year in orbit, the NASA/ESA Hubble Space Telescope has released a beautiful new image of part of NGC 2174, also known as the Monkey Head Nebula. This colourful region is ...
NASA historic Earth images still hold research value
(Phys.org) —NASA's Seasat satellite became history long ago, but it left a legacy of images of Earth's ocean, volcanoes, forests and other features that were made by the first synthetic aperture radar ever ...
Is an earthquake behind carbon dating of Shroud of Turin image?
(Phys.org) —An earthquake in Old Jerusalem might be behind the famous image of the Shroud of Turin, says a group of researchers led by Alberto Carpinteri of the Politecnico di Torino in Italy in an article published in ...
Arctic lakes show climate on thin ice
(Phys.org) —Ice in northern Alaska's lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments.
A small step toward discovering habitable Earths
University of Arizona researchers snapped images of a planet outside our solar system with an Earth-based telescope using essentially the same type of imaging sensor found in digital cameras instead of an ...
NASA Mars orbiter examines dramatic new crater
(Phys.org) —Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.
Neutrons help visualising materials
New imaging methods will offer new possibilities to physicists, material scientists, engineers, palaeontologists, archaeologists, and others, so that they can obtain better information on their objects of study.
Southern Ocean iron cycle gives new insight into climate change
An international team of researchers analyzed the available data taken from all previous studies of the Southern Ocean, together with satellite images taken of the area, to quantify the amount of iron supplied ...
Messier 7: Diamonds in the tail of the scorpion
(Phys.org) —A new image from ESO's La Silla Observatory in Chile shows the bright star cluster Messier 7. Easily spotted with the naked eye close to the tail of the constellation of Scorpius, it is one ...
A complete medical check-up on a chip
(Phys.org) —About the size of a stapler, this new handheld device developed at EFPL is able to test a large number of proteins in our body all at once-a subtle combination of optical science and engineering.
