New research may improve the accuracy of "cosmic yardsticks"

Astronomers have discovered evidence that could help solve a long standing dispute over the origin of Type Ia supernovae, by observing the youngest example of the titanic explosions located to date. The light from the rare breed of supernovae is used by scientists as a cosmic yard stick to chart the expansion of our universe.Read More

Solar activity sparks powerful X-ray aurorae on Jupiter

Solar activity can prompt a massive increase in the intensity of Jupiter's polar aurorae, according to a new study drawing on data collected by NASA's Chandra X-ray Observatory. Charged particles from a powerful solar storm were observed creating an impressive light show as they struck the Jovian planet in October 2011.Read More

X-rays and nanoparticles combine to kill cancer deep in the body

Cancer may be terrifying, but cancerous cells aren't actually that difficult to kill. The tricky bit is doing so without killing the host or making them dreadfully ill in the process. The key is treatments that only target the cancer cells while leaving the surrounding healthy tissue alone. By combining X-rays with nanoparticles, a team of researchers from the Centre for Nanoscale BioPhotonics (CNBP) in Australia has found a way of combating cancer deep inside the body in this way using a simple chemical.Read More

Laser X-rays to nab nuclear smugglers

With over 100 million cargo containers in transit each year, screening them for illicit nuclear material is a major problem. To keep commerce flowing while maintaining an eye on nuclear terrorism and smuggling, a team of scientists at the University of Nebraska-Lincoln (UNL) is developing a laser-based X-ray machine that can image a uranium disk the size of a stack of three US nickels hidden between three-inch (7.6 cm) steel panels.Read More

Kinect measures body thickness to lessen radiation exposure from X-rays

The depth-sensing capabilities of the Microsoft's Kinect has seen it put to use in a number of unexpected applications, such as helping Parkinson's sufferers to walk and the visually impaired to practice yoga. Scientists now claim to have expanded the applications for the gaming technology to include a more precise approach to X-ray imaging, which they say can limit exposure to radiation by measuring the thickness of a subject's body parts.Read More

Study suggests an even distribution of elements throughout the universe

A new study carried out by the Japan Aerospace Exploration Agency (JAXA) suggests that when the universe was between two to four billion years old, the elements used to create everything from the largest star to the human race were evenly spread across a vast area of the cosmos. The study focused on an enormous structure of galaxies known as the Virgo Galaxy Cluster, which sits roughly 54 million light years from Earth and harbors over 2,000 galaxies.Read More

Orbital telescopes detect increased activity from the supermassive black hole at the heart of the Milky Way

Three space-based observatories appear to have picked up an unusual increase in activity from the supermassive black hole located at the center of our galaxy. According to the data, the black hole known as Sagittarius A* (Sgr A*), which has a mass of roughly 4 million times our Sun, is throwing out ten times the usual amount of bright X-ray flares.Read More
