[ Watch the Video: Light Echoes Around RS Puppis ] redOrbit Staff & Wire Reports - Your Universe Online Observations from the NASA/ESA Hubble Space Telescope, collected over the span of five weeks, show the variable star RS Puppis growing alternately brighter and dimmer – a phenomenon known as a light echo. Hubble monitored RS Puppis, which is ten times more massive and roughly 15,000 times more luminous than the sun, and captured it at different stages throughout its...

Solar Winds Examined By XMM-Newton

Lee Rannals for redOrbit.com — Your Universe Online While solar wind is a common occurrence in our Solar System, a study of a new, more fierce wind has been completed using the European Space Agency's XMM-Newton space observatory. These massive stellar winds derive from rare, giant stars which burn their nuclear fuel more rapidly than stars like the Sun, and that live for millions of years before exploding into a supernova. Massive stars lose a significant fraction of their...

WISE Images Supernova's Rose

About 3,700 years ago, people on Earth would have seen a brand-new bright star in the sky. It slowly dimmed out of sight and was eventually forgotten, until modern astronomers later found its remains, called Puppis A. In this new image from NASA's Wide-field Infrared Survey Explorer (WISE), Puppis A looks less like the remains of a supernova explosion and more like a red rose. Puppis A (pronounced PUP-pis) was formed when a massive star ended its life in a supernova, the most brilliant and...

XMM-Newton has discovered an exploding star in the Milky Way. Usually that would be important in itself, but this time there is a special twist. Calculations show that the explosion must have been clearly visible to the unaided eye but was missed by the legions of star watchers around the planet. On October 9, 2007, ESA's orbiting X-ray observatory XMM-Newton was turning from one target to another. As it did so, it passed across a bright source of X-rays that no one was expecting. The source...

Astronomers calibrate the distance scale of the Universe Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance "Our measurements with ESO's New Technology Telescope at La Silla allow us to obtain the most accurate distance to a Cepheid," says Pierre Kervella, lead-author of the paper reporting...

One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed. Astronomers used Chandra to observe a neutron star, known as RX J0822-4300, over a period of about five years. During that span, three Chandra observations clearly show the neutron star moving away from the center of the Puppis A supernova remnant. This remnant is the stellar debris field created during the same...

JPL -- NASA's Spitzer Space Telescope has spotted what may be the dusty spray of asteroids banging together in a belt that orbits a star like our Sun. The discovery offers astronomers a rare glimpse at a distant star system that resembles our home, and may represent a significant step toward learning if and where other Earths form. "Asteroids are the leftover building blocks of rocky planets like Earth," said Dr. Charles Beichman of the California Institute of Technology, Pasadena, Calif....

Puppis Constellation -- Containing the brightest star visible on earth, the constellation of Canis Major is one of the few constellations in the heavens which resembles what it is supposed to be: a large dog. Its neighbor, Puppis, on the other hand, boasts no bright stars, and is difficult at best for even seasoned observers to identify. Stellar beacons notwithstanding, both of these constellations are rich in open clusters, as they lie along the winter Milky Way. Several...
