zombie star after supernova
2014-08-07 07:21:49

Felicia Chou, NASA Headquarters and Donna Weaver / Ray Villard, Space Telescope Science Institute Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint supernova may have left behind a surviving portion of the dwarf star -- a sort of zombie...

Cosmic microwave background
2014-08-06 03:00:27

Hillary Sanctuary/Mediacom, Ecole Polytechnique Fédérale de Lausanne The Planck Telescope allowed physicists to draw the most detailed map of the first light emitted after the Big Bang. Some of its features do not entirely fit the standard cosmological theory, but scientists have discovered that these anomalies could be explained by how the data was processed. Last year, the Planck Telescope revealed the most detailed picture of the cosmic microwave background, the relic radiation...

Messier 33
2014-08-06 11:14:16

ESO Messier 33, otherwise known as NGC 598, is located about three million light-years away in the small northern constellation of Triangulum (The Triangle). Often known as the Triangulum Galaxy it was observed by the French comet hunter Charles Messier in August 1764, who listed it as number 33 in his famous list of prominent nebulae and star clusters. However, he was not the first to record the spiral galaxy; it was probably first documented by the Sicilian astronomer Giovanni Battista...

extreme temperature evolution for WISE J0304-2705

redOrbit Staff & Wire Reports - Your Universe Online An object that is currently cool as a planet might have spent much of its youth as hot as a star, according to a new research paper appearing in the latest edition of the journal Monthly Notices of the Royal Astronomical Society. The object currently fluctuates between 200 and 300 degrees Fahrenheit (100 to 150 degrees Celsius), which is in between the temperatures of Earth and Venus, lead investigator David Pinfield of the...

Southwest Research Institute Scientists on Sunday highlighted an impressive list of achievements in researching the outer heliosphere at the 40th International Committee on Space Research (COSPAR) Scientific Assembly in Moscow. “Between NASA’s Voyager and IBEX missions, it’s an incredible time for outer heliospheric science,” says Dr. Dave McComas, IBEX principal investigator and assistant vice president of the Space Science and Engineering Division at Southwest Research...

Karen C. Fox, NASA's Goddard Space Flight Center Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares – a constant peppering of impulsive bursts of heating, none of which can be individually detected -- provide the mysterious extra heat. [ Watch:...

April Flowers for redOrbit.com - Your Universe Online University of Bristol’s professor of Aerospace Engineering Ashley Dale cautions that “solar super-storms” are going to cause “catastrophic” and “long-lasting” impacts if we continue to ignore the threat of such storms. Dale is a member of the international task force SolarMAX, which was designed to identify the risks of a solar storm and how humanity could minimize the risks. He believes that a particularly violent...

Stellar Astrophysics

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

Tropic of Capricorn
2013-02-21 13:31:57

The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
