Astronomy & Space news

	New dwarf galaxies discovered in orbit around the Milky Way A team of astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. The findings, from newly-released imaging data taken from the Dark Energy Survey, may help unravel the mysteries behind dark matter, the invisible substance holding galaxies together.
	Mysterious phenomena in a gigantic galaxy-cluster collision Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.
	Detection of gamma rays from a newly discovered dwarf galaxy may point to dark matter A newly discovered dwarf galaxy orbiting our own Milky Way has offered up a surprise—it appears to be radiating gamma rays, according to an analysis by physicists at Carnegie Mellon, Brown, and Cambridge universities. The exact source of this high-energy light is uncertain at this point, but it just might be a signal of dark matter lurking at the galaxy's center.
	Intergalactic GPS will guide you through the stars Lost in the Universe? Need some precise navigation through the bulk of stars in the night sky? Don't worry, there will be an instrument for that - the Multi-Object Optical and Near-infrared Spectrograph (MOONS) at the European Southern Observatory's (ESO) Very Large Telescope (VLT) in northern Chile. The spectrograph, dubbed the intergalactic GPS, will help us navigate through the billions of stars in our galaxy and create a comprehensive map of its structure. "One of the first science cases is to help build up maps of the central region of our galaxy," William Taylor of the UK Astronomy Technology Centre (UK ATC) in Edinburgh, UK, told astrowatch.net. "With infrared light we have the power to see through the dust that obscures many of the objects in the central region of our galaxy, and so we can map the speeds and types of stars in the central bulge of the Milky Way."
	Galileo satellites ready for fuelling as launcher takes shape All the elements for this month's Galileo launch are coming together at Europe's Spaceport in French Guiana. As the two satellites undergo final testing and preparations, the first part of their Soyuz launcher has also been integrated.
	Orion's launch abort system motor exceeds expectations Three seconds. That's all it took for the attitude control motor of NASA's Orion Launch Abort System (LAS) to prove that its material can survive not only the intense temperatures, pressures, noise and vibrations experienced during a launch emergency but also 40 percent beyond. The LAS is being designed to bring a crew to safety should there be a problem in the launch pad or during ascent.
	Scientists prepare for Large Synoptic Survey Telescope When the Large Synoptic Survey Telescope begins in 2022 to image the entire southern sky from a mountaintop in Chile, it will produce the widest, deepest and fastest views of the night sky ever observed – and a flood of 6 million gigabytes of data per year that are expected to provide new insights into dark matter, dark energy and other cosmic mysteries.
	Image: Taking a closer look at Orion after successful flight test Engineers across the country have been busy taking a closer look at NASA's Orion spacecraft and the data it produced during its successful flight test in December 2014. Inside the Launch Abort System Facility at NASA's Kennedy Space Center in Florida, Orion was lifted using a special crane for removal of its heat shield on Feb. 13, 2015.
	Testing astronauts' lungs in Space Station airlock Air was pumped out of the International Space Station's air lock for the first time in the name of science last week. Inside the cylindrical Quest airlock, ESA astronaut Samantha Cristoforetti and NASA's Terry Virts monitored their breathing for researchers back on Earth.
	Cosmologists spends month searching for meteorites in Anarctica Every austral summer, a group of volunteers heads off to a remote region of Antarctica to set up a field camp on the ice. For the next month, they search the ice and nearby debris piles left by glaciers for dark rocks that might be extraterrestrial in origin. The program is called the Antarctic Search for Meteorites (ANSMET).
	How long does it take to get to Pluto? It's a long way out to the dwarf planet Pluto. So, just how fast could we get there?
	Scientists find rare dwarf satellite galaxy candidates in Dark Energy Survey data Scientists on two continents have independently discovered a set of celestial objects that seem to belong to the rare category of dwarf satellite galaxies orbiting our home galaxy, the Milky Way.
	Cosmic dust discs withstand hellfire A team of scientists led by astronomers at the University of Bonn discovered an unusual phenomenon in the centre of the Milky Way: They detected about 20 rotating dust and gas discs in each cluster hosting exceptionally large and hot stars. The existence of these discs in the presence of the destructive UV radiation field of their massive neighbours came as a surprise. The science team is pondering how these rotating discs are able to withstand evaporation under these extreme conditions. The results are published in the most recent edition of the journal Astronomy & Astrophysics.

	Researchers devise a way to alter feelings attached to memories in mice while they sleep (Medical Xpress)—A team of researchers in France has found a way to alter how a mouse "feels" about something it has remembered. In their paper published in the journal Nature Neuroscience, the team describes how they recorded brain activity while mice visited new areas of their cage, then stimulated their brains while they slept in a way that made them favor the place they had visited and remembered.
	Cellular scissors chop up HIV virus Imagine a single drug that could prevent human immunodeficiency virus (HIV) infection, treat patients who have already contracted HIV, and even remove all the dormant copies of the virus from those with the more advanced disease. It sounds like science fiction, but Salk scientists have gotten one step closer to creating such a drug by customizing a powerful defense system used by many bacteria and training this scissor-like machinery to recognize the HIV virus.

The situation is frustrating to both patients and their physicians.
Regular colonoscopy can prevent bowel cancer Bowel cancer is one of the most common types of cancer. The prognosis depends greatly on the stage at which the tumour is discovered. Colonoscopy is regarded as the best method for identifying pre-cancerous changes. If these changes are treated promptly, the disease can be stopped in its tracks. To mark "International Bowel Cancer Month" in March 2015, experts at the MedUni Vienna are strongly recommending that all men should have a colonoscopy from the age of 45 and women from the age of 50.

Canada has one of the highest rates in the world of IBD and while immigrants to Canada have lower rates of IBD compared to Canadian-born residents, that risk goes up in immigrants who are younger at arrival to Canada. In addition, Canadian-born children of immigrants from some regions have a higher risk of developing IBD.

But birth rates vary from region to region, in some cases dramatically. Sociologist Barbara Fulda explains the influence of regional cultural norms.
