This telescope takes the night shift and constantly scans the night sky for planets so that we can get some shut-eye.
A newly discovered pulsar has the widest orbit ever discovered around a neutron star and is part of a rare double neutron star system, and could help astronomers gain new insight as to how such systems form and evolve, the National Radio Astronomy Observatory (NRAO) has announced.
Astronomers from the Australian National University analyzing a small red dwarf star located some 500 light years from Earth have made a startling discovery: the presence of a massive gas giant orbiting far closer to its tiny parent star than should be possible.
You could name a planet after your mom or your cat, or even your favorite TV character.
Researchers have for the first time captured detailed images of heat rising from the horseshoe-shaped lava lake on Io, the innermost moon of Jupiter. Cool!
This new exoplanet appears to be just too big for its star and it’s got the astronomers frantically scratching their heads.
NASA sounding rocket was launched towards a supernova remnant, with the goal of examining the X-rays emitted by the object to determine the composition of this 20,000-year-old explosion’s debris.
These black holes are always hungry and are huge! Constantly gorging yourself on gas 'donuts' can do that to you.
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...
