In Star Wars, the Death Star is a massive spaceship capable of destroying a planet with just one shot of its laser, but a recently-discovered white dwarf star may have ripped apart a planet at its core by coming too close to it, making it a real-life Death Star.

By observing colliding galaxies with the ESO’s Very Large Telescope (VLT) and the Hubble Space Telescope, astronomers have found evidence suggesting for the first time that dark matter may interact with other dark matter in a way other than through gravity.

Thanks to NASA’s Spitzer Space Telescope and a technique known as microlensing, a team of astronomers has located one of the most distant exoplanets ever discovered – a remote gas planet located approximately 13,000 light-years from Earth.

Chuck Bednar for redOrbit.com - @BednarChuck After two years worth of work by some 300 researchers, the Dark Energy Survey (DES) project have unveiled the first in a series of dark matter maps showing the distribution of the mysterious substance experts believe makes up roughly 27 percent of the universe. According to BBC News, the maps show how conglomerations of dark matter change over time and was created using a 570-megapixel camera attached to the Victor Blanco telescope in Chile....

NASA has released the first color map of Ceres, and while the data is still said to have come from early observational stages, it nonetheless indicates that the dwarf planet was shaped by a series of diverse processes since its formation some 4.5 billion years ago.

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

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...
