The Bad Astronomer writes "As much as 90% of previously hidden galaxies in the distant Universe have been found by astronomers using the Very Large Telescope in Chile. Previous surveys had looked for distant (10 billion light years away) galaxies by searching in a wavelength of ultraviolet light emitted by hydrogen atoms — distant young galaxies should be blasting out this light, but very few were detected. The problem is that the ultraviolet light never gets out of the galaxies, so we never see them. In this new study, astronomers searched a different wavelength emitted by hydrogen, and voila, ten times as many galaxies could be seen, meaning 90% of them had been missed before."

krou writes "With a budget of £500, Robert Harrison used cheap parts, a weather balloon, some duct tape, a digital camera, and a GPS device to capture some great photos of the earth from space that resulted in NASA calling him to find out how he had done it. 'A guy phoned up who worked for NASA who was interested in how we took the pictures,' said Mr Harrison. 'He wanted to know how the hell we did it. He thought we used a rocket. They said it would have cost them millions of dollars.' The details of his balloon are as follows: he used 'an ordinary Canon camera mounted on a weather balloon,' 'free software' that 'reprogrammed the camera to wake up every five minutes and take eight photographs and a video before switching off for a rest.' He also ensured the camera was 'wrapped in loft insulation' to make sure it could operate at the cold temperatures. The GPS device allowed him to pinpoint the balloon's location, and retrieve the camera when it fell down to earth attached to a small parachute."

alphadogg writes to tell us that one freshman class has a little more than usual to be excited about. When students at Abilene Christian University showed up for their first days of class they were greeted with the choice of either a new iPhone 3g or an iPod Touch plus a package of custom web apps to use on them. "The hardware is part of the Texas university's pilot mobile learning project, which has been gestating for over a year. About 650 first-year students chose the iPhone, and about 300 the iPod Touch, which is a very similar device but without the 3G radio (both devices incorporate an 802.11g Wi-Fi adapter). ACU pays for the hardware, student (or their parents) select and pay for their monthly AT&T service plan."
