BENTON HARBOR, Mich., Feb.
The Coma Cluster, a massive grouping of galaxies located 300 million light-years from Earth, is home to a group of 47 galaxies that are rich in dark matter and may be so-called ‘failed’ galaxies, researchers from Yale University report in a new study.
Astronomers have used NASA's Hubble Space Telescope to take the most detailed edge on picture to date of a large disk of gas and dust encircling the 20 million-year-old star Beta Pictoris.
NASA's voyage to Europa might be our last chance to find alien life on the Jovial moon.
The heliosphere actually looks like a giant cooked shrimp.
Dark matter, the hypothetical matter that is cannot be observed using telescopes but is believed to be responsible for huge gravitational effects in the universe, could be indirectly responsible for wiping out the dinosaurs, according to one New York University professor.
The magnetic field of the sun plays a crucial role in shaping the heliosphere—the domain of the sun—by accelerating the solar wind into a pair of jets College
LA JOLLA, Calif., Feb. 19, 2015 /PRNewswire/ -- Regulus Therapeutics Inc.
Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy.
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...
