Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.
World-leading scientists will push the boundaries of studies on how to deflect asteroids and manipulate space debris, as the University of Strathclyde gets set to transform international space research.
The algorithm uses a variety of image processing steps to segment the image, first into coarser (foreground) and finer (background) grains. The image is then further segmented until most grains are outlined. The code processes a single image within 1 to 5 minutes.
Researchers assessed the details of halogen variability and an unusual process that may influence it. The group investigated the potential for an existing halogen cycle on Mars, which would alter the current paradigm of halogens distributed mostly by water-related processes.
The Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way. This glittering cluster contains over 100 000 stars, and could also hide a rare type of black hole at its center.
A new, detailed radio image showed that what astronomers thought was one galaxy actually is two, superimposed on the sky. The alignment allows using the farther one as an unexpected tool for studying the foreground galaxy.
The Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.
Researchers from Bern have developed a method to simplify the search for Earth-like planets: By using new theoretical models they rule out the possibility of Earth-like conditions, and therefore life, on certain planets outside our solar system - and limit their search by doing so.
Astronomers at ESO have captured the best image so far of the clouds around the star cluster NGC 3572. This image shows how these clouds of gas and dust have been sculpted into bubbles, arcs and the odd features known as elephant trunks by the stellar winds flowing from this gathering of hot stars. The brightest of these cluster stars are much heavier than the Sun and will end their short lives as supernova explosions.
Brown researchers have helped to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. That means a sample-return mission planned by the Russian space agency could sample two celestial bodies for the price of one.
