Face recognition for galaxies: Artificial intelligence brings new tools to astronomy

Mon, 23 Apr 18 00:08:20 -0700

A machine learning method called 'deep learning,' which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. In a new study, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.

'Rip Van Winkle' plants hide underground for up to 20 years

Thu, 19 Apr 18 00:10:10 -0700

Scores of plant species are capable of living dormant under the soil for up to 20 years, enabling them to survive through difficult times, a new study has found.

Hubble celebrates 28th anniversary with a trip through the Lagoon Nebula

Thu, 19 Apr 18 00:09:50 -0700

This colorful cloud of glowing interstellar gas is just a tiny part of the Lagoon Nebula, a vast stellar nursery. This nebula is a region full of intense activity, with fierce winds from hot stars, swirling chimneys of gas, and energetic star formation all embedded within a hazy labyrinth of gas and dust. Hubble used both its optical and infrared instruments to study the nebula, which was observed to celebrate Hubble's 28th anniversary.

Two Hubble views of the same stellar nursery

Thu, 19 Apr 18 00:09:40 -0700

These NASA Hubble Space Telescope images compare two diverse views of the roiling heart of a vast stellar nursery, known as the Lagoon Nebula. The images, one taken in visible and the other in infrared light, celebrate Hubble's 28th anniversary in space.

Wed, 18 Apr 18 00:10:20 -0700

Nationally, urban/community tree cover declined from 42.9 percent to 42.2 percent between 2009-2014. This translates to losing an estimated 36 million trees or approximately 175,000 acres of tree cover annually.

New research seeks to optimize space travel efficiency

Wed, 18 Apr 18 00:13:40 -0700

Sending a human into space and doing it efficiently presents a galaxy of challenges. Koki Ho, University of Illinois assistant professor in the Department of Aerospace Engineering, and his graduate students, Hao Chen and Bindu Jagannatha, explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, published today in the Journal of Spacecraft and Rockets, to create a framework to optimize fuel and other resources.

Alpine grassland productivity not sensitive to climate warming on third pole

Tue, 17 Apr 18 00:13:40 -0700

HE Jinsheng's research team at the Northwest Institute of Plateau Biology, collaborating with scientists from Peking University, established a warming-by-precipitation manipulative experiment at the Haibei National Field Research Station of Alpine Grassland Ecosystem. By combining the field manipulative experiment, 32 years of field monitoring and a meta-analysis from nine sites across the plateau, the impact of climate change on species composition and net primary productivity in Tibetan alpine grasslands was investigated.

Freeing electrons to better trap them

Mon, 16 Apr 18 00:10:00 -0700

Half a century ago, Walter Henneberger wondered if it was possible to free an electron from its atom, but still make it stay around the nucleus. Scientists considered it was impossible. For the first time, physicists from UNIGE and MBI managed to control the shape of the laser pulse to keep an electron both free and bound to its nucleus, and were at the same time able to regulate the electronic structure of this atom.

The names were proposed by the New Horizons team and approved by IAU Working Group for Planetary System Nomenclature.

UNH researchers find combination for small data storage and tinier computers

Thu, 12 Apr 18 00:12:00 -0700

It may sound like a futuristic device out of a spy novel, a computer the size of a pinhead, but according to new research from the University of New Hampshire, it might be a reality sooner than once thought. Researchers have discovered that using an easily made combination of materials might be the way to offer a more stable environment for smaller and safer data storage, ultimately leading to miniature computers.

Thu, 12 Apr 18 00:10:40 -0700

Planets orbiting 'short-period' binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars' evolution, according to new research from the University of Washington.

Outback radio telescope listens in on interstellar visitor

Tue, 10 Apr 18 00:16:10 -0700

A telescope in outback Australia has been used to listen to a mysterious cigar-shaped object that entered our Solar System late last year. When 'Oumuamua was first discovered, astronomers thought it was a comet or an asteroid from within the Solar System. But after studying its orbit and discovering its long, cylindrical shape, they realised 'Oumuamua was neither and had come from interstellar space.

New cellular insights in bone development

Fri, 06 Apr 18 00:07:10 -0700

Most of us don't think about our teeth and bones until one aches or breaks. A team of engineers at Washington University in St. Louis looked deep within collagen fibers to see how the body forms new bone and teeth, seeking insights into faster bone healing and new biomaterials.

MIPT physicists design a model of Martian winter

Thu, 05 Apr 18 00:09:30 -0700

A team of researchers from MIPT and their German and Japanese colleagues have designed a numerical model of the annual water cycle in the Martian atmosphere. In this study, the MIPT team expanded the analysis to include smaller particles that are more elusive. As a result, the calculations turned out to be more accurate and consistent with the data obtained from Mars orbiters.

Giant solar tornadoes put researchers in a spin

Thu, 05 Apr 18 00:02:40 -0700

Despite their appearance solar tornadoes are not rotating after all, according to a European team of scientists. A new analysis of these gigantic structures, each one several times the size of the Earth, indicates that they may have been misnamed because scientists have so far only been able to observe them using 2-dimensional images.

Tue, 03 Apr 18 00:01:50 -0700

An international team of researchers has imaged newly forming jets of plasma from a massive black hole with unprecedented accuracy. Radio images made with a combination of telescopes in space and on the ground resolve the jet structure merely a couple of hundred black hole radii or 12 light days from its launching site.

Dispatch from the field II: Students describe an elusive spider while stationed in Borneo

Tue, 03 Apr 18 00:05:20 -0700

Students taking part in a recent ecology field course in Borneo described the first male of an elusive species of orb-weaving spider known for its striking red and blue colors. Despite being stationed in the field, they managed to compile their manuscript and submit it to the technologically advanced open-access Biodiversity Data Journal. A few days post-submission, their article was published along with all underlying biodiversity data ready to access and reuse.

Astro-ecology: Saving endangered animals with software for the stars

Tue, 03 Apr 18 00:09:20 -0700

A collaboration between astrophysicists and ecologists at Liverpool John Moores University (LJMU) is helping to monitor rare and endangered species and stop poaching. Astrophysical software and techniques are applied to thermal infrared imagery captured by drones to automatically detect and identify animals -- even at night, when most poaching activity occurs. The project will be presented by Claire Burke at the European Week of Astronomy and Space Science (EWASS).
