Complex organic molecules discovered in infant star system

This is an artist impression of the protoplanetary disk surrounding the young star MWC 480. ALMA has detected the complex organic molecule methyl cyanide in the outer reaches of the disk in the region where comets are believed to form. This is another indication that complex organic chemistry, and potentially the conditions necessary for life, is universal.For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery, made with...

Sexing Stegosaurus

Some <i>Stegosaurus</i> had wide plates, some had tall, with the wide plates being up to 45 percent larger overall than the tall plates.  According to a new study by University of Bristol, UK student, Evan Saitta, the tall-plated <i>Stegosaurus</i> and the wide-plated <i>Stegosaurus</i> were not two distinct species, nor were they individuals of different age: they were actually males and females.  This is the first convincing evidence for sexual differences in a species of dinosaur.Stegosaurus, a large, herbivorous dinosaur with two staggered rows of bony plates along its back and two pairs of spikes at the end of its tail, lived roughly 150 million...

Hubble finds phantom objects near dead quasars

These Hubble Space Telescope images reveal a set of bizarre, greenish looping, spiral, and braided shapes around eight active galaxies. The galaxies host a bright quasar that may have illuminated the structures.NASA's Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded.

Scientists see deeper Yellowstone magma

A new University of Utah study in the journal <i>Science</i> provides the first complete view of the plumbing system that supplies hot and partly molten rock from the Yellowstone hotspot to the Yellowstone supervolcano. The study revealed a gigantic magma reservoir beneath the previously known magma chamber. This cross-section illustration cutting southwest-northeast under Yelowstone depicts the view revealed by seismic imaging. Seismologists say new techniques have provided a better view of Yellowstone's plumbing system, and that it hasn't grown larger or closer to erupting. They estimate the annual chance of a Yellowstone supervolcano eruption is 1 in 700,000.University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger...

Dark Energy Survey creates detailed guide to spotting dark matter

This is the first Dark Energy Survey map to trace the detailed distribution of dark matter across a large area of sky. The color scale represents projected mass density: red and yellow represent regions with more dense matter. The dark matter maps reflect the current picture of mass distribution in the universe where large filaments of matter align with galaxies and clusters of galaxies. Clusters of galaxies are represented by gray dots on the map -- bigger dots represent larger clusters. This map covers three percent of the area of sky that DES will eventually document over its five-year mission.Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful...
