Title: The evolutionary status of the UX Orionis star RZ Piscium Authors: V. P. Grinin, I. S. Potravnov, F. A. Musaev The star RZ Psc is one of the most enigmatic members of the UX Ori star family. It shows all properties that are typical for these stars (the light variability, high linear polarization...

A close look at the protoplanetary disk around a young star by two teams of astronomers using the Subaru telescope on Mauna Kea has led to the unexpected discovery of two banana-shaped arcs facing each other. The disk, which surrounds the star HD142527, also shows a gap that could be the tumul...

The colourful, intricate shapes in these NASA Hubble Space Telescope images reveal how the glowing gas ejected by dying Sun-like stars evolves dramatically over time. These gaseous clouds, called planetary nebulae, are created when stars in the last stages of life cast off their outer layers of m...

Fossils of huge 'wolf-sized' otter unearthed in China Scientists have unearthed fossils of an intriguingly large otter as big as a wolf that frolicked in rivers and lakes in a lush, warm and humid wetlands region in south-western China about 6.2 million years ago. Researchers say the outsized otte...

Small stretches of seemingly useless DNA harbour a big secret, say researchers at the Stanford University School of Medicine. There's one problem: We don't know what it is. Although individual laboratory animals appear to live happily when these genetic ciphers are deleted, these snippets have...

Mountain Baekdu, a dormant volcano on the border between North Korea and China, is showing signs of a possible eruption in the near future, experts warned Tuesday. According to historical records, Baekdu was an active volcano. Major activity in the 1960s created a caldera on its peak, whose circum...

NuSTAR Finds New Clues to 'Chameleon Supernova' One supernova in particular is challenging astronomers' models of how exploding stars distribute their elements. The supernova SN 2014C dramatically changed in appearance over the course of a year, apparently because it had thrown off a lot of mat...
