It was one month ago Monday that NASA’s Dawn spacecraft entered orbit around the dwarf planet Ceres, and the US space agency issued an update this week assuring that the probe was still in good health and performing “flawlessly” as it continued its research.
SUNNYVALE, Calif., April 7, 2015 /PRNewswire/ -- Cepheid (Nasdaq: CPHD) today announced that it has appointed Mr.
Our Sun goes through a few activity cycles and a new study has identified one such cycle that is almost seasonal in nature. According to the report, published in the journal Nature Communications, the nearly two-year cycle appears to be caused by shifts in the bands of powerful magnetic fields in each solar hemisphere. These bands also aid in shaping and approximately 11-year solar cycle that is part of a lengthier cycle that lasts approximately 22 years.
WASHINGTON, April 6, 2015 /PRNewswire-USNewswire/ -- The public has until Friday, April 24 to help name new features on Pluto and its orbiting satellites as they are discovered by NASA's New

Unlike most types of stars, which are just as likely as not to have companions and be part of a binary system, an ancient type of variable stars known as RR Lyrae stars seemed to always live out their lives on their own – something that has long puzzles astronomers.
NASA studied the 'crime scene' left behind from an explosion of an Ia supernova and discovered that a single white dwarf star is to blame.
These phantom quasars are brighter than they should be, what's going on? Hint: it's not aliens.
Gas giants surviving their death spiral formation has had scientists puzzled for many moons, but new research suggests it's heat that aids their survival.
For years, physicists have claimed that information sent through a black hole is lost forever, but new research published recently in the journal Physical Review Letters suggests otherwise.
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.

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...
