Meet the loneliest galaxies in the universe as they were flung from their home clusters due to gravitational turbulence.
The George Observatory re-opens the famous 36-inch Gueymard Research Telescope to the public after a lengthy restoration of its primary mirror. Houston, TX (PRWEB)
WASHINGTON, April 23, 2015 /PRNewswire-USNewswire/ -- The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in the 25th anniversary NASA Hubble Space
Experts hunting for extraterrestrial life on extrasolar planets and elsewhere in the solar system are joining forces in what NASA is calling “an unprecedented initiative dedicated to the search for life on planets outside our solar system,” the US space agency announced Monday.
While the overwhelming majority of NASA’s recent R&D efforts are focused on getting humans to Mars, they aren’t ignoring other planets, as evidenced by an ongoing project that would send a piloted, helium-filled airship to explore the atmosphere of Venus.
Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common Hunt), and are published yesterday in the journal Astronomy and Astrophysics.
Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies’ supermassive black holes will form a “binary,” or two black holes in such close orbit they
Later this week, stargazers will be able to view the annual Lyrid meteor shower at its peak, as experts are predicting that the oldest-known meteor shower in the universe will offer viewers 10 to 20 meteors per hour on Wednesday and/or Thursday mornings.
You mean to tell us there are no Wookies, Klingons, or Sontarans out there?
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...
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...
